Article 22 Cooperation with third parties 22.1. In order to enhance the ACP States' capacity to build up their technical skills and to improve the know-how of their consultants, cooperation partnership arrangements shall be encouraged between consultancy firms, consulting engineers, experts and institutions of the EEC and those of the ACP States. To this end, the Commission and the ACP States shall make every effort to: (a) encourage by means of temporary associations, sub-contracting or the use of experts who are nationals of the ACP States in teams employed by consultancy firms, consulting engineers or institutions in the EEC; (b) inform tenderers in the tender dossier of the selection criteria and preferences provided for in these general regulations, particularly those relating to the encouragement of the use of ACP human resources. 22.2. The contracting authority may, in the invitation to tender or during the negotiation of a contract, propose to prospective tenderers the assistance of other firms, national experts or consultants to be selected by mutual agreement. This cooperation may take the form either of a joint venture, or of a subcontract or of on-the-job training of trainees. 22.3.

The parties involved shall undertake to cooperate mutually and shall agree on the procedure for such cooperation and in particular the responsibilities arising from it. Article 23 Independence of tenderers 23.1. If a tenderer in the case of service contracts has entered into a legal relationship with natural or legal persons who might participate in the carrying out of works, or the provision of supplies, which the services are intended to define or prepare, or if he otherwise maintains with them special relations likely to compromise his independence, he shall inform the contracting authority thereof in his tender, or at the time of negotiation of the contract, or whenever such circumstances arise before the award of the contract. 23.2. If, notwithstanding such information, a contract is concluded with the said tenderer, the contracting authority shall reserve that right to exclude the natural or legal persons concerned from participating in carrying out such works or providing such supplies. Article 24 Pricing of tenders 24.1.

Prices should not be of such a nature as to distort the comparison of tenders or to result in interim payments which are disproportionate to the value of the work done. 24.4. Tenders shall be expressed in the national currency of the State of the contracting authority. The tenderer may in addition express the equivalent value of his tender in either ecus or in the currency of the country in which he has his registered place of business. The conversion rate shall be that in force 30 days prior to the latest date fixed for the submission of tenders. 24.5. A tenderer may request in his tender that a justified part, expressed as a percentage of the tender price, be paid directly to him in foreign currency. The justification required shall be assessed in the light of the verifiable facts as regards the real origin of the works, supplies or sevice to be performed and the expenditure to which they give rise. 24.6. The price offered by the tenderer shall take into account the tax arrangements applicable as set out in the Convention. Article 25 Period of validity 25.1. Tenderers shall remain bound by their tenders for the period prescribed by the contracting authority, pursuant to Article 13. Any tender valid for a shorter period may be rejected by the contracting authority. The period fixed by the contracting authority shall be sufficient to permit evaluation and comparison of tenders, for obtaining all necessary clearances and approvals, and for the notification of the award of contract. The validity period should normally not exceed 120 days from the final date fixed for the submission of tenders but it may vary depending on the nature and complexity of the contract. 25.2. In exceptional circumstances, prior to the expiry of the original tender validity period, the contracting authority may request the tenderer for a specified extension in the period of validity. Tenderers agreeing to the request will neither be required nor permitted to modify their tenders, but will be required to extend the validity of their tender guarantees correspondingly. The provisions of Article 26 regarding discharge and forfeiture of the tender guarantee shall continue to apply during the extended period of tender validity. 25.3.

Unless otherwise provided in the instructions to tenderers, tenderers for works and supplies contracts shall, as an earnest of their tenders, provide a guarantee. The tender dossier shall specify the amount of this guarantee which shall not be less than 1 % of the amount of the tender, but shall in no case exceed 2 %. 26.2. The tender guarantee shall be provided in the form of a bank guarantee, a banker's draft, a certified cheque, a bond provided by an insurance or bonding company, an irrevocable letter of credit or a cash deposit made with the contracting authority. If the tender guarantee is to be established in the form of a bank guarantee, a banker's draft, a certified cheque or a bond, it shall be issued by a bank, insurance or bonding company, approved by the contracting authority and established in an ACP or a Member State. The bank guarantee or the bond shall be in strict conformity with the tender guarantee form included in the tender dossier or, in the case of direct agreement contract, in the special conditions. Whatever form it takes, the guarantee shall be independent and payable on first demand and valid for at least 60 days beyond the tender validity period. 26.3. Any tender not accompanied by an acceptable tender guarantee may be rejected by the contracting authority. 26.4. The tender guarantees of tenderers who have not been selected will be released not later than 60 days after the expiration of the tender validity period, as extended where appropriate in accordance with Article 25 (2), or upon the award of the contract, whichever is earlier. 26.5. The tender guarantee of the successful tenderer shall be discharged when the tenderer has signed the contract and furnished the required performance guarantee, to the satisfaction of the contracting authority. 26.6. The tender guarantee may be called up without notice: (a) if a tenderer withdraws his tender during the period of tender validity of his tender; (b) in the case of the successful tenderer, if he fails within the specified time limit to sign the contract or furnish the required performance guarantee. Article 27 Variant solutions 27.1. Unless otherwise stated in the instructions to tenderers, tenderers may submit a tender based on a variant solution. The instructions to tenderers must specify any limitations, design criteria and other requirements applicable to a variant solution. Unless stated otherwise in the instructions to tenderers, the submission of a tender based on a variant solution is conditional upon the submission of a tender based on the conforming solution. 27.2. Variant solutions may not derogate from the requirements of these general regulations. Tenders based on the tender dossier and those for variant solutions shall be evaluated simultaneously. 27.3. The instructions to tenderers must state whether the tenderer submitting a variant solution is to be responsible for the design of the variant solution, and if this is the case, must specify procedures, in particular for checking, revision and approval. 27.4. The submission of any variant solution shall comprise: (a) an individual tender for the variant solution; (b) a demonstration of the benefit of the variant solution over the conforming solution, including quantifiable justification of any economic advantage; (c) a draft of the amendments to the technical provisions of the special conditions necessitated by the variant solution; (d) the drawings and specifications provided for in the conforming solution, but not affected by the variant solution; (e) the drawings and specifications affected by the variant solution; (f) a technical note on the conception of the variant solution and where appropriate, drawings and the calculations; (g) for lump sum contracts, an itemized breakdown of the overall price as modified by the variant solution; (h) for unit-price contracts, a bill of quantities and/or a price schedule as modified by the variant solution. Article 28 Pre-tender visit 28.1. The tenderer is advised to visit and inspect the place where the contract is to be executed and its surroundings and obtain for himself, on his own responsibility, all information that may be necessary for preparing the tender and entering into a contract. The costs of visiting the place where the contract is to be executed shall be borne by the tenderer. 28.2. The tenderer and any of his personnel or agents will, so far as is practicable, be granted permission by the contracting authority to enter the place where the contract is to be executed for the purpose of such inspection, provided that the tenderer, his personnel or agents will release and indemnify the contracting authority and its personnel and agents from and against all liability in respect thereof. Accordingly, the tenderer will be responsible for any personal injury, whether fatal or otherwise, loss or damage which, but for acting on such permission, would not have arisen. 28.3. Without prejudice to the laws and regulations on immigration of the State of the contracting authority, the ACP State concerned shall grant an entry permit to any person who substantiates his eligibility in terms of Article 4 as a participant in an invitation to tender, or any agent of such person, for the purpose of carrying out visits enabling him to prepare his tender.

Tenders must be received by the contracting authority at the address and not later than the date and time specified in accordance with Article 13. In determining this date, the contracting authority must ensure that adequate time is allowed, taking into account the nature, size, complexity, and location of the intended project and other relevant factors. Such period shall not, however, be less than 90 days for an open invitation to tender. 30.2. The contracting authority may, at its discretion, extend the deadline referred to in Article 30 (1) for the submission of tenders by amending the tender dossier in accordance with Article 18, in which case all previous rights and obligations of the contracting authority and tenderers, subject to the previous deadline, will thereafter be subject to the deadline as extended. Should a tenderer exercise his right of withdrawal after receiving notice of the extention, his tender shall be returned to him and his tender guarantee shall be released after the tender opening session. 30.3. Any tenders received by the contracting authority after the deadline for receipt of tenders prescribed by the contracting authority, in accordance with Articles 13 (4) (g) and 18 shall be rejected and returned to the tenderer after the tender opening session.

The instructions to tenderers shall specify in each case whether the documents relating to the price proposal shall be placed together with the technical proposal in one envelope or in separate envelopes. In the latter case, the price proposal shall be placed in a separate identifiable envelope, bearing the words 'tender price`, which shall be sealed and placed together with the technical proposal in the envelope referred to in Article 31 (1). Article 32 Withdrawals and amendments 32.1. Any tenderer may modify or withdraw his tender before the deadline referred to in Article 30 (3), provided that written notice of such modification or withdrawal is received by the contracting authority prior to that deadline. 32.2. The tenderer's modification or withdrawal notice shall be prepared, sealed, marked and dispatched in accordance with the provisions of Article 31. A withdrawal notice may also be sent by personal delivery or by telex, cable, or facsimile transmission but followed by a signed confirmation copy, post marked not later than the deadline for submission of tenders. Withdrawals will be unconditional and will end further participation in the tendering procedure. 32.3. N° tender may be modified subsequent to the deadline referred to in Article 30 (3), except in accordance with Article 34 (1). 32.4. N° tender may be withdrawn in the interval between the deadline referred to in Article 30 (3) and the expiration of the period of tender validity.

On receipt of the tenders, the envelopes shall be entered in a special register in the order in which they arrive. The registration number and the date and time of arrival shall be recorded on the envelope. Envelopes remain sealed and be kept in a safe place until they are opened under the conditions set out in Articles 33 (2) and 33 (3). 33.2. At a public tender opening, the tenderers' names, the tender prices, written notifications of tender modifications and withdrawals, the presence of the requisite tender guarantee, and such other details as the contracting authority may consider appropriate shall, if any, be announced. In the case of a 'two-envelope` system as mentioned in Article 31 (2) the announcement shall include the fact that no price envelope has been opened. 33.3. Opening and examination of tenders shall comply with the rules of the ACP States concerned and with the Convention, and shall be for the purpose of checking whether the tenders are complete, whether the requisite tender guarantee has been furnished, whether the documents have been properly signed and whether the tenders are generally in order. 33.4. The envelopes which bear the words 'tender price` in accordance with Article 31 shall not be opened until the work of evaluating the tenders, other than the prices, has been completed. 33.5. Only the tenders contained in those envelopes which have been received not later than the deadline referred to in Article 30 (3) shall be taken into consideration in the evaluation. 33.6. The contracting authority shall prepare, for its own records, minutes of the tender opening, including the information disclosed to those present in accordance with Article 33 (2). 33.7. After the public opening of tenders, information relating to the examination, clarification, evaluation and comparison of tenders and recommendations concerning the award of the contract shall not be disclosed to tenderers or other persons not officially concerned with such process. 33.8. Any attempt by a tenderer to influence the contracting authority in the process of examination, clarification, evaluation and comparison of tenders, and in decisions concerning the award of the contract, shall result in the rejection of his tender. 33.9. The delegate shall be present at the opening of tenders, and shall receive a copy of each tender. Article 34 Evaluation of tenders 34.1. To facilitate the examination, evaluation and comparison of tenders, the contracting authority may ask each tenderer individually for clarification of his tender, including breakdowns of unit prices. The request for clarification and the response shall be in writing and communicated by any of the means referred to in Article 12, but no change in the price or substance of the tender shall be sought, offered or permitted except as required to confirm the correction of arithmetic errors discovered by the contracting authority during the evaluation of the tenders pursuant to Article 34 (7). 34.2. Prior to the detailed evaluation of tenders, the contracting authority shall determine whether each tender is substantially responsive to the requirements of the tender dossier. 34.3. For the purpose of Article 34, a responsive tender is one which conforms to all the terms, conditions and specifications of the tender dossier without material deviation or reservation. A material deviation or reservation is one which affects the scope, quality or performance of the contract, or which, in any substantial way, is inconsistent with the tender dossier or limits the contracting authority's rights or the tenderer's obligations under the contract, and affects unfairly the competitive position of tenderers presenting responsive tenders. 34.4. If a tender is not responsive to the tender dossier, it shall be rejected by the contracting authority, and may not subsequently be made responsive by correction or withdrawal of the deviation or reservation. 34.5. Tenders determined to be responsive shall be evaluated technically for conformity with the invitation to tender dossier and the provisions of Article 36, and then ranked on the basis of their technical qualities. The special conditions shall, where appropriate, specify the detailed criteria for technical evaluation. 34.6. Following the completion of the technical evaluation, tenders which, on the basis of Article 34 (5), are technically responsive shall be evaluated financially. Tenders shall be compared in the national currency. 34.7. Tenders determined to be responsive shall be checked by the contracting authority for any arithmetic errors in computation and summation. Errors shall be corrected by the contracting authority as follows: (a) where there is a discrepancy between amounts in figures and also in words, the amount in words shall prevail; and (b) except for lump-sum contracts, where there is a discrepancy between the unit price and the total amount derived from the multiplication of the unit price and quantity, the unit price as quoted shall prevail, unless in the opinion of the contracting authority there is an obvious error in the unit price, in which event the total amount as quoted shall prevail and the unit price shall be corrected by the contracting authority. 34.8. The amount stated in the tender, corrected if necessary by the contracting authority, in accordance with Article 34 (7), shall be considered as binding upon the tenderer. If the tenderer does not accept the corrected amount of the tender, his tender shall be rejected. 34.9. After tenders have been evaluated fully in accordance with the provisions of Article 34, responsive tenders shall be grouped into tenders offered by those tenderers eligible for preference under Article 9 and tenders offered by other tenderers. For the purposes of further evaluation and comparison of tenders only, the tender prices, corrected where necessary, of the tenderers not eligible for preference shall be increased by the percentage margin of preference. Further details of the procedures to be used in giving effect to the margin of preference provisions of Article 9 shall be as laid down by the contracting authority in the tender dossier. 34.10. The evaluation proceedings shall be recorded in properly signed minutes which shall not be made public or communicated to any tenderer. A copy of these minutes will be sent to the delegate. Article 35 Annulment of the tender procedure 35.1. The contracting authority may, prior to awarding the contract, without thereby incurring any liability to the tenderers, and notwithstanding the stage reached in the procedures leading to the conclusion of the contract: (a) either decide to annul the tender procedure in accordance with Article 35 (2), or order that the procedure be recommenced, if necessary, using another method; or (b) where the project is divided into lots, award only certain of the lots and possibly decide that the others are to be the subject of another tender or other tenders, if necessary, using another method. 35.2. The annulment by the contracting authority of a tender procedure may take place in the following cases: (a) if no tender is responsive to the tender dossier; (b) if no tender satisfies the criteria for the award of the contract as set out in Article 36; (c) if the economic or technical data of the project have been altered; (d) if exceptional circumstances render normal performance of the contract impossible; (e) if every tender received exceeds the financial resources earmarked for the contract; (f) if the tenders received contain serious irregularities resulting in interference with the normal play of market forces; or (g) if there has been no competition. 35.3. In the event of annulment of any tender procedure, tenderers who are still bound by their tenders shall be notified thereof by the contracting authority. Such tenderers shall not be entitled to compensation; they shall be entitled to the immediate release of the tender guarantee. 35.4. When the annulment of the tender procedure is caused by circumstances which do not necessitate the opening of tenders, the unopened and sealed envelopes containing the price proposals, where appropriate, and, in any event, the other elements of the tender shall be returned to the tenderers at the tenderers' cost. AWARD OF CONTRACT Article 36 Selection 36.1. The contracting authority shall award the contract to the tenderer: (a) whose tender is found to be responsive to the tender dossier; and (b) for works and supply contracts, who has offered the most advantageous tender as assessed, inter alia, on the basis of: ii(i) the price, the operating and maintenance costs; i(ii) the qualifications of, and the guarantees offered by the tenderers, as well as the technical qualities of the tender, including the offer of an after-sales service in the ACP State; (iii) the nature of, the conditions and the time limits for performing the contract, and the adaptation to local conditions; (c) for service contracts, who offers the most advantageous tender taking into account, inter alia, the price, the technical value of the tender, the organization and the methodology proposed for the provision of the services, as well as the competence, independence and availability of the personnel proposed. 36.2.

The contractor shall draw up, and submit for the approval of the supervisor, a programme of performance of the contract, in accordance with the special conditions. The programme shall contain at least the following: (a) the order in which the contractor proposes to carry out the works; (b) the time limits within which submission and approval of the drawings are required; (c) a general description of the methods which the contractor proposes to adopt for carrying out the works; and (d) such further details and information as the supervisor may reasonably require. 17.2. The approval of the programme by the supervisor shall not relieve the contractor from any of his obligations under the contract. 17.3. N° material alteration to the programme shall be made without the approval of the supervisor. If, however, the progress of the works does not conform to the programme, the supervisor may instruct the contractor to revise the programme and submit the revised programme to him for approval. Article 18 Detailed breakdown of prices 18.1. Where appropriate and within a period of not more than 20 days following the supervisor's reasoned request, the contractor shall provide a detailed breakdown of his rates and prices, where such breakdown is required for any purpose under the contract. 18.2. After the notification of award, the contractor shall, within the time limit stated in the special conditions, provide to the supervisor for his information only, a detailed cash flow estimate, in quarterly periods, of all payments which may be due to the contractor under the contract. The contractor shall subsequently supply revised cash flow estimates at quarterly intervals, if so required by the supervisor. The communication shall not impose any liability whatsoever on the contracting authority or the supervisor. Article 19 Contractor's drawings 19.1. The contractor shall submit to the supervisor for approval: (a) such drawings, documents, samples and/or models as may be specified in the contract within the time limits laid down therein or in the programme of performance; (b) such drawings as the supervisor may reasonably require for the performance of the contract. 19.2. If the supervisor fails to notify his decision of approval referred to in Article 19 (1) within the time limits referred to in the contract or the approved programme of performance, such drawings, documents, samples or models shall be deemed to be approved at the end of the time limits specified. If no time limit is specified, they shall be deemed to be approved 30 days after receipt. 19.3. Approved drawings, documents, samples and models shall be signed or otherwise identified by the supervisor and shall not be departed from except as otherwise instructed by the supervisor. Any contractor's drawings, documents, samples or models which the supervisor fails to approve, shall be forthwith modified to meet the requirements of the supervisor and resubmitted by the contractor for approval. 19.4. The contractor shall supply additional copies of approved drawings in the form and number stated in the contract or in subsequent administrative orders. 19.5. The approval of the drawings, documents, samples or models by the supervisor shall not relieve the contractor from any of his obligations under the contract. 19.6. The supervisor shall have the right at all reasonable times to inspect all contract drawings, documents, samples or models at the contractor's premises. 19.7. Before provisional acceptance of the works, the contractor shall supply operation and maintenance manuals together with drawings, which shall be in such detail as will enable the contracting authority to operate, maintain, adjust and repair all parts of the works. Unless otherwise stated in the special conditions, the manuals and drawings shall be in the language of the contract and in such forms and numbers as stated in the contract. The works shall not be considered to be completed for the purpose of provisional acceptance until such manuals and drawings have been supplied to the contracting authority. Article 20 Sufficiency of tender prices 20.1. The contractor shall be deemed to have inspected and examined the site and its surroundings and to have satisfied himself before submitting his tender, as to the nature of the ground and sub-soil, and to have taken into account the form and nature of the site, the extent and nature of the work and materials necessary for the completion of the works, the means of communication with and access to the site, the accommodation he may require and in general to have obtained for himself all necessary information as to risks, contingencies and all other circumstances influencing or affecting his tender. 20.2. The contractor shall be deemed to have satisfied himself before submitting his tender as to the correctness and sufficiency of the tender and of the rates and prices stated in the bill of quantities or price schedule which shall, except in so far as it is otherwise provided in the contract, cover all his obligations under the contract. 20.3. Since the contractor is deemed to have determined his prices on the basis of his own calculations, operations and estimates, he shall carry out without additional charge any work which is the subject of any item whatsoever in his tender for which he neither indicates a unit price nor a firm sum. Article 21 Exceptional risks 21.1. If during the execution of the works the contractor encounters artificial obstructions or physical conditions which could not reasonably have been foreseen by an experienced contractor, and if the contractor is of the opinion that additional costs will be incurred and/or an extension of the period of performance of the contract will be necessary as a result of this, he shall give notice to the supervisor in accordance with Articles 35 and/or 55. The contractor shall specify in such notice the artifical obstrucions and/or physical conditions, giving details of the anticipated effects thereof, the measures he is taking or intends to take and the extent of the anticipated delay in or interference with the execution of the works. 21.2. Following receipt of the notice, the supervisor may inter alia: (a) require the contractor to provide an estimate of the cost of the measures he is taking or intends to take; (b) approve measures referred to in Article 21.2 (a) with or without modification; (c) give written instructions as to how the artificial obstructions or physical conditions are to be dealt with; Article 46 Advances 46.1. If the special conditions so provide, advances shall be granted to the contractor, at his request, for operations connected with the execution of the works, in the cases listed hereinafter: (a) as a lump-sum advance enabling him to meet expenditure resulting from the commencement of the contract; (b) if he affords proof of the conclusion of a contract for the purchase or order of materials, plant, equipment, machines and tools, necessary for the execution of the contract, and of any other substantial prior expenses such as the acquisition of patents or study costs. 46.2. The special conditions shall state the amount of the advances which shall not exceed 10 % of the original contract price in respect of the lump-sum advance in Article 46 (1) (a) and 20 % of such prices for all other advances in Article 46 (1) (b). 46.3. N° advance shall be granted until: (a) the conclusion of the contract; (b) provision to the contracting authority by the procedure of the performance guarantee in accordance with Article 15; and by (c) provision to the contracting authority by the contractor of a separate directly liable guarantee for the full amount of the advance by the institutions referred to in Article 15 (3), which shall remain effective until the advance has been completely repaid by the contractor out of interim payments under the contract. 46.4. The contractor shall use the advance exclusively for operations connected with the execution of the works. Should the contractor misuse any portion of the advance, it shall become due and repayable immediately and no further advance payments will be made to him. 46.5. Should the advance guarantee cease to be valid and the contractor fail to re-validate it, either a deduction equal to the amount of the advance may be made by the contracting authority from future payments due to the contractor under the contract, or the contracting authority may apply the provisions of Article 15 (6). 46.6. If the contract is terminated for any reason whatsoever, the guarantees securing the advances may be invoked forthwith in order to repay the balance of the advances still owed by the contractor, and the guarantor shall not delay payment or raise objection for any reason whatever. 46.7. The advance guarantee provided for in Article 46 shall be released as and when advances are repaid. 46.8. Further conditions and procedures for granting and repaying advances shall be as laid down in the special conditions. Article 47 Retention sum 47.1. The sum which shall be retained from interim payments by way of guarantee to meet the contractor's obligations during the maintenance period, and the detailed rules governing that guarantee, shall be stipulatd in the special conditions, provided that it shall, in no case, exceed 10 % of the contract price. 47.2. Subject to the approval of the contracting authority, the contractor may, if he so wishes, substitute, not later than the date fixed for the commencement of the works, these retention sums by a retention guarantee issued in accordance with Article 15 (3). 47.3. The sum retained or the retention guarantee shall be released within 90 days of the date of final acceptance of the works. Article 48 Revision of prices 48.1. Unless otherwise stipulated in the special conditions, and except as provided in Article 48 (4) the contract shall be at fixed prices which shall not be revised. 48.2. Where prices may be revised under the contract, such revision shall take into account variations in the prices of significant local or external elements which serve as a basis for the calculation of the tender price, such as manpower, services, materials and supplies, as well as charges laid down by law or regulation. The detailed rules for the revision shall be as laid down in the special conditions. 48.3. Prices contained in the contractor's tender shall be deemed: (a) to have been arrived at on the basis of the conditions in force 30 days prior to the latest date fixed for submission of tenders; or in the case of direct agreement contracts, on the date of the contract; (b) to have taken account of the legislation and the relevant tax arrangements applicable at the reference date fixed in Article 48 (3) (a). 48.4. In the event of changes to, or introduction of, any national or State statute, ordinance, decree or other law, or any regulation or by-law of any local or other public authority, after the date stated in Article 48 (3) which causes a change in the contractual relationship between the parties to the contract, the contracting authority and the contractor shall consult on how best to proceed further under the contract, and may as a result of such consultation decide: (a) to modify the contract; or (b) on payment of compensation for the resulting imbalance by one party to the other; or (c) to terminate the contract by mutual agreement. 48.5. In the event of a delay in the execution of the works for which the contractor is responsible, or at the end of the period of performance revised as necessary in accordance with the contract, there shall be no further revision of prices within the 30 days before provisional acceptance, except for the application of new price indexation, if this is to the benefit of the contracting authority. Article 49 Measurement 49.1. The following methods shall apply to the valuation of works contracts: (a) For lump-sum contracts, the amount due under the contract shall be determined on the basis of the breakdown of the overall contract price, or on the basis of a breakdown expressed as a percentage of the contract price corresponding to completed stages of the works. Where items are accompanied by quantities, these shall be firm quantities for which the contractor has submitted his all-in price, and shall be paid for irrespective of the quantities of work actually carried out. (b) For unit price contracts: ii(i) the amount due under the contract shall be calculated by applying the unit rates to the quantities actually executed for the respective items, in accordance with the contract; i(ii) the quantities set out in the bill of quantities shall be the estimated quantities of the works, which shall not be taken as the actual and correct quantities of the works to be executed by the contractor in fulfilment of his obligations under the contract; (iii) the supervisor shall determine by measurement the actual quantities of the works executed by the contractor, and these shall be paid for in accordance with Article 50. Unless otherwise provided in the special conditions no additions shall be made to the items in the bill of quantities except as a result of a variation in accordance with Article 37 or other provision of the contract entitling the contractor to additional payment; (iv) the supervisor shall, when he requires any parts of the works to be measured, give reasonable notice to the contractor to attend, or to send a qualified agent to represent him. The contractor or his agent shall assist the supervisor in making such measurements and shall furnish all particulars required by the supervisor. Should the contractor not attend, or omit to send such agent, the measurement made by the supervisor or approved by him shall be binding on the contractor; i(v) the works shall be measured net, notwithstanding any general or local custom, except where otherwise provided for in the contract. (c) For cost-plus contracts, the amount due under the contract shall be determined on the basis of actual costs with an agreed addition for overheads and profit. The special conditions shall stipulate the information which the contractor is required to submit to the supervisor for the purpose of Article 49 (1) (c) and the manner in which it should be submitted. 49.2. Where an item in the contract is indicated as 'provisional` the provisional sum set aside for it shall not be taken into account in calculating the percentages referred to in Article 37. Article 50 Interim payments 50.1. Unless otherwise specified in the special conditions, the contractor shall submit an application for interim payment to the supervisor at the end of each period referred to in Article 50 (7) in a form approved by the supervisor. The application shall include the following items, as applicable: (a) the estimated contract value of the permanent works executed up to the end of the period in question; (b) an amount reflecting any revision of prices pursuant to Article 48; (c) an amount to be withheld as retention sum under Article 47; (d) any credit and/or debit for the period in question in respect of plant and materials on site intended for, but not yet incorporated in, the permanent works in the amount and under the conditions set out in Article 50 (2); (e) an amount to be deducted on account of the advance repayment under the provisions of Article 46; and (f) any other sum to which the contractor may be entitled under the contract. 50.2. The contractor shall be entitled to such sums as the supervisor may consider proper in respect of plant and materials intended for, but not yet incorporated in, the permanent works provided that: (a) the plant and materials conform with the specifications for the permanent works and are set out in batches in a way that they may be recognised by the supervisor; (b) such plant and materials have been delivered to the site, and are properly stored and protected against loss or damage or deterioration to the satisfaction of the supervisor; (c) the contractor's record of requirements, orders, receipts and use of plant and materials under the contract are kept in a form approved by the supervisor and such records are available for inspection by the supervisor; (d) the contractor submits with his statement, the estimated value of the plant and materials on site together with such documents as may be required by the supervisor for the purpose of valuation of the plant and materials and providing evidence of ownership and payment therefor; and (e) where the special conditions so provide, ownership of the plant and materials referred to in Article 43 shall be deemed to be vested in the contracting authority. 50.3. Approval by the supervisor of any interim payment certified by him in respect of plant and materials pursuant to Article 50 shall be without prejudice to the exercise of any power of the supervisor under the contract to reject any plant or materials which are not in accordance with the provisions of the contract. 50.4. The contractor shall be responsible for any loss or damage to, and for the cost of storing and handling of, such plant and materials on site and shall effect such additional insurance as may be necessary to cover the risk of such loss or damage from any cause. 50.5. Within 30 days of receipt of the said application for interim payment, it shall be approved or amended in such manner that, in the supervisor's opinion, the application reflects the amount due to the contractor in accordance with the contract. In cases where there is a difference of opinion as to the value of an item, the supervisor's view shall prevail. On determination of the amount due to the contractor, the supervisor shall issue to the contracting authority and the contractor an interim payment certificate for the amount due to the contractor and shall inform the contractor of the works for which payment is being made. 50.6. The supervisor may, by an interim payment certificate, make any corrections or modifications to any previous certificate issued by him and shall have power to modify the valuation in or withhold the issue of, any interim payment certificate if the works or any part thereof are not being carried out to his satisfaction. 50.7. Unless the special conditions provide otherwise, the frequency shall be one interim payment per month. Article 51 Final statement of account 51.1. Not later than 90 days after the issue of the final acceptance certificate referred to in Article 62, the contractor shall submit to the supervisor a draft final statement of account with supporting documents showing in detail the value of the work done in accordance with the contract, together with all further sums which the contractor considers to be due to him under the contract in order to enable the supervisor to prepare the final statement of account. The special conditions may, however, in accordance with Article 51 (6) state that the draft final statement of account and further proceedings related thereto, be dealt with before the issue of the provisional acceptance certificate. 51.2. Within 90 days after receipt of the draft final statement of account and of all information reasonably required for its verification, the supervisor shall prepare the final statement of account, which determines: (a) the amount which in his opinion is finally due under the contract; and (b) after establishing the amounts previously paid by the contracting authority and all sums to which the contracting authority is entitled under the contract, the balance, if any, due from the contracting authority to the contractor, or from the contractor to the contracting authority, as the case may be. 51.3. The supervisor shall issue to the contracting authority or to its duly authorized representative, and to the contractor, the final statement of account showing the final amount to which the contractor is entitled under the contract. The contracting authority or its duly authorized representative and the contractor shall sign the final statement of account as an acknowledgement of the full and final value of the work performed under the contract and shall promptly submit a signed copy to the supervisor. However, the final statement of account shall not include amounts in dispute which are the subject of negotiations, conciliation, arbitration or litigation. 51.4. The final statement of account signed by the contractor shall constitute a written discharge of the contracting authority confirming that the total in the final statement of account represents full and final settlement of all monies due to the contractor under the contract, other than those amounts which are the subject of amicable settlement, arbitration or litigation. However, such discharge shall become effective only after any payment due in accordance with the final statement of account has been made and the performance guarantee referred to in Article 15 has been returned to the contractor. 51.5. The contracting authority shall not be liable to the contractor for any matter or thing whatsoever arising out of, or in accordance with, the contract or execution of the works, unless the contractor shall have included a claim in respect thereof in his draft final statement of account. 51.6. The provisions of Article 51 may be varied by the special conditions having regard to the practices in the State of the contracting authority. Article 52 Direct payments to sub-contractors 52.1. When the supervisor receives a claim from a sub-contractor duly approved under Article 7 to the effect that the contractor has not met his financial obligations so far as the sub-contractor is concerned, the supervisor shall give notice to the contractor either to pay the sub-contractor or to inform him of the reasons why payment should not be made. Should such payment not be made, or reasons not be given within the period of notice, the supervisor may, after satisfying himself that the work has been carried out, certify, and the contracting authority shall meet the debt claimed by the sub-contractor out of the sums remaining due to the contractor. The contractor shall remain entirely responsible for the work in respect of which direct payment has been made. 52.2. If the contractor gives adequate reasons for refusing to meet all or part of the debt claimed by the sub-contractor, the contracting authority shall only pay to the sub-contractor such sums as are not in dispute. Sums claimed by the sub-contractor in respect of which the contractor has given adequate reasons for his refusal to pay shall be paid by the contracting authority only after the parties have come to an amicable settlement, or after the decision of an arbitrating authority or after a judgment of a court has been duly notified to the supervisor. 52.3. Direct payments to sub-contractors shall not exceed the value at contract prices of the services performed by the sub-contractors for which they request payment; the value at contract prices shall be calculated or assessed on the basis of the bill of quantities, the price schedule or the breakdown of the lump sum price. 52.4. Direct payments to sub-contractors shall be made entirely in the national currency of the country in which the contract is performed, or partly in such national currency and partly in foreign currency, in accordance with the contract. 52.5. Where direct payments to sub-contractors are made in foreign currency, they shall be calculated in accordance with Article 56. They shall not result in any increase in the total amount payable in foreign currency, as stipulated in the contract. 52.6. The provisions of Article 52 shall apply subject to the requirements of the law applicable by virtue of Article 54 concerning the right to payment of creditors who are beneficiaries of an assignment of credit or of a collateral security. Article 53 Delayed payments 53.1. Payment to the contractor of the amounts due under each of the interim payment certificates and the final statement of account issued by the supervisor shall be made by the contracting authority within 90 days of such certificate or statement being delivered to the contracting authority. If the period laid down for payment has been exceeded, the contractor shall qualify for interest calculated pro rata on the basis of the number of days delay at the rate specified in the special conditions, subject to a maximum period, also specified therein. The contractor shall be entitled to such payment without prejudice to any other right or remedy under the contract. In the case of the final statement of account, the interest for the delayed payment shall be calculated on a daily basis at the rate specified in the special conditions. 53.2. Any default in payment of more than 120 days from the expiry of the period laid down in Article 53 (1) shall entitle the contractor either not to perform the contract or to terminate it. Article 54 Payments to third parties 54.1. All orders for payments to third parties may be carried out only after an assignment made in accordance with Article 6. The assignment shall be notified to the contracting authority. 54.2. Notification of beneficaries of the assignment shall be the sole responsibility of the contractor. 54.3. In the event of a legally binding attachment of the property of the contractor affecting payments due to him under the contract, without prejudice to the time limit laid down in Article 53, the contracting authority shall have 30 days, starting from the day when it receives notification of the definitive lifting of the obstacle to payment, to resume payments to the contractor. Article 55 Claims for additional payment 55.1. If under the contract there are circumstances which the contractor considers entitle him to additional payment, the contractor shall: (a) if he intends to make any claim for additional payment, give to the supervisor notice of his intention or make such claim within 15 days after the said circumstances become known to the contractor, stating the reason for his claim; and (b) as soon as is reasonably practicable after the date of such notice but not later than 60 days after such notice, unless otherwise agreed by the supervisor, submit to the supervisor full and detailed particulars of his claim. In any event, such particulars shall be submitted no later than the date of submission of the draft final statement of account. The contractor shall thereafter promptly submit such further particulars as the supervisor may reasonably require to assess the validity of the claim. 55.2. When the supervisor has received the full and detailed particulars of the contractor's claim that he requires, he shall, without prejudice to Article 21 (4), after due consultation with the contracting authority and, where appropriate, the contractor, determine whether the contractor is entitled to additional payment and notify the parties accordingly. 55.3. The supervisor may reject any claim for additional payment which does not comply with the requirements of Article 55. Article 56 Payments in foreign currency Where under the contract the contractor is entitled to payments in foreign currency, the rates of exchange for calculating the payments shall be those prevailing, as determined by the Central Bank of the State of the contracting authority, 30 days prior to the latest date fixed for the submission of tenders for the contract. Such rates of exchange shall not be varied. ACCEPTANCE AND MAINTENANCE Article 57 General clauses 57.1. Verification of the works by the supervisor with a view to provisional or final acceptance shall take place in the presence of the contractor. The absence of the contractor shall not be a bar to verification on condition that the contractor has been summoned in due form at least 30 days prior to the date of verification. 57.2. Should exceptional circumstances make it impossible to ascertain the state of the works or otherwise proceed with their acceptance during the period fixed for provisional or final acceptance, a statement certifying such impossibility shall be drawn up by the supervisor after consultation, where possible, with the contractor. The verification shall take place and a statement of acceptance or rejection shall be drawn up by the supervisor within 30 days following the date on which such impossibility ceases to exist. The contractor shall not invoke these circumstances in order to avoid his obligation to present the works in a state suitable for acceptance. Article 58 Tests on completion 58.1. The works shall not be accepted until the prescribed verifications and tests have been carried out at the expense of the contractor. The contractor shall notify the supervisor of the date on which such verification and tests may commence. 58.2. Works which do not satisfy the terms and conditions of the contract, or in the absence of such terms and conditions, which are not carried out in accordance with trade practices in the State where the works are located, shall, if required, be demolished and rebuilt by the contractor or repaired to the satisfaction of the supervisor, otherwise this shall be done as of right after due notice at the expense of the contractor, by order of the supervisor. The supervisor may also require the demolition and reconstruction by the contractor, or repair to the satisfaction of the supervisor, under the same conditions of work, in which unacceptable materials have been used, or carried out in the periods of suspension provided for in Article 38. Article 59 Partial acceptance 59.1. The contracting authority may make use of the various structures, parts of structures or sections of the works forming part of the contract as and when they are completed. Any taking over of the structures, parts of structures or sections of the works by the contracting authority shall be preceded by their partial provisional acceptance. However, works may in cases of urgency be taken over prior to acceptance provided an inventory of outstanding work is drawn up by the supervisor and agreed to by the contractor and the supervisor beforehand. Once the contracting authority has taken possession of a structure, a part thereof or section of the works, the contractor shall no longer be required to make good any damage resulting otherwise than from faulty construction or workmanship. 59.2. The supervisor may, at the request of the contractor and if the nature of the works so permits, proceed with partial provisional acceptance, provided that the structures, parts of structures or sections of the works are completed and suited to the use as described in the contract. 59.3. In the cases of partial provisional acceptance referred to in Article 59 (1) and 59 (2) the maintenance period provided for in Article 62 shall, unless the special conditions provide otherwise, run as from the date of such partial provisional acceptance. Article 60 Provisional acceptance 60.1. The works shall be taken over by the contracting authority when they have satisfactorily passed the tests on completion and a certificate of provisional acceptance has been issued or is deemed to have been issued. 60.2. The contractor may apply, by notice to the supervisor, for a certificate of provisional acceptance not earlier than 15 days before the works, in the contractor's opinion, are complete and ready for provisional acceptance. The supervisor shall within 30 days after the receipt of the contractor's application either: (a) issue the certificate of provisional acceptance to the contractor with a copy to the contracting authority stating, where appropriate, his reservations, and, inter alia, the date on which, in his opinion, the works were completed in accordance with the contract and ready for provisional acceptance; or (b) reject the application giving his reasons and specifying the action which, in his opinion, is required of the contractor for the certificate to be issued. 60.3. If the supervisor fails either to issue the certificate of provisional acceptance or to reject the contractor's application within the period of 30 days, he shall be deemed to have issued the certificate on the last day of that period. The certificate of provisional acceptance shall not be deemed to be an admission that the works have been completed in every respect. If the works are divided by the contract into sections, the contractor shall be entitled to apply for separate certificates for each of the sections. 60.4. Upon provisional acceptance of the works, the contractor shall dismantle and remove temporary structures as well as materials no longer required for use in connection with the performance of the contract. He shall also remove any litter or obstruction and redress any change in the condition of the site as required by the contract. 60.5. Immediately after provisional acceptance, the contracting authority may make use of all the works as completed. Article 61 Maintenance obligations 61.1. The contractor shall be responsible for making good any defect in, or damage to, any part of the works which may appear or occur during the maintenance period or within 30 days after its expiration and which arises either from: (a) the use of defective plant or materials or faulty workmanship or design of the contractor; and/or (b) any act or omission of the contractor during the maintenance period. 61.2. The contractor shall at his own cost make good the defect or damage as soon as practicable. The maintenance period for all items replaced or renewed shall recommence from the date when the replacement or renewal was made to the satisfaction of the supervisor. If the contract provides for partial acceptance, the maintenance period shall be extended only for the part of the works affected by the replacement or renewal. 61.3. If any such defect appears or such damage occurs, during the period referred to in Article 61 (1), the contracting authority or the supervisor shall notify the contractor. If the contractor fails to remedy a defect or damage within the time limit stipulated in the notification, the contracting authority may: (a) carry out the works himself, or employ someone else to carry out the works, at the contractor's risk and cost, in which case the costs incurred by the contracting authority shall be deducted from monies due to or from guarantees held against, the contractor, or from both; or (b) terminate the contract. 61.4. If the defect or damage is such that the contracting authority has been deprived substantially of the whole or a part of the benefit of the works, the contracting authority shall, without prejudice to any other remedy, be entitled to recover all sums paid in respect of the parts of the works concerned together with the cost of dismantling such parts and clearing the site. 61.5. In case of emergency, where the contractor cannot be reached immediately or, having been reached, is unable to take the measures required, the contracting authority or the supervisor may have the work carried out at the expense of the contractor. The contracting authority or the supervisor shall as soon as practicable inform the contractor of the action taken. 61.6. Where the special conditions stipulate that the maintenance work, necessitated by normal wear and tear, shall be carried out by the contractor, such work shall be paid for from a provisional sum. Deterioration resulting from the circumstances provided for in Article 21 or from abnormal use shall be excluded from this obligation unless it reveals a fault or defect justifying the request for repair or replacement under Article 61. 61.7. The maintenance obligations shall be stipulated in the special conditions and technical specifications. If the duration of the maintenance period is not specified, it shall be 365 days. The maintenance period shall commence on the date of provisional acceptance. 61.8. After provisional acceptance and without prejudice to the maintenance obligations referred to in Article 61, the contractor shall no longer be responsible for risks which may affect the works and which result from causes not attributable to him. However, the contractor shall be responsible as from the date of provisional acceptance for the soundness of the construction, as laid down in the special conditions or in the law of the State of the contracting authority. Article 62 Final acceptance 62.1. Upon the expiration of the maintenance period, or where there is more than one such period, upon the expiration of the latest period, and when all defects or damage have been rectified, the supervisor shall issue to the contractor a final acceptance certificate and a copy thereof to the contracting authority stating the date on which the contractor completed his obligations under the contract to the supervisor's satisfaction. The final acceptance certificate shall be given by the supervisor within 30 days after the expiration of the above stated period, or as soon thereafter as any works as instructed, pursuant to Article 61, have been completed to the satisfaction of the supervisor. 62.2. The works shall not be considered as completed until a final acceptance certificate shall have been signed by the supervisor and delivered to the contracting authority, with a copy to the contractor. 62.3. Notwithstanding the issue of the final acceptance certificate, the contractor and the contracting authority shall remain liable for the fulfilment of any obligation incurred under the contract prior to the issue of the final acceptance certificate, which remains unperformed at the time such final acceptance certificate is issued. The nature and extent of any such obligation shall be determined by reference to the provisions of the contract. BREACH OF CONTRACT AND TERMINATION Article 63 Breach of contract 63.1. Either party commits a breach of contract where he fails to discharge any of his obligations under the contract. 63.2. Where a breach of contract occurs, the party injured by the breach shall be entitled to the following remedies: (a) damages; and/or (b) termination of the contract. 63.3. Damages may be either: (a) general damages; or (b) liquidated damages. 63.4. In any case where the contracting authority is entitled to damages, he may deduct such damages from any sums due to the contractor or from the appropriate guarantee. Article 64 Termination by the contracting authority 64.1. The contracting authority may, at any time and with immediate effect, terminate the contract, except as provided for under Article 64 (2). 64.2. Except as otherwise provided in these general conditions, the contracting authority may, after giving seven days notice to the contractor, terminate the contract and expel the contractor from the site in any of the cases where: (a) the contractor fails to carry out the works substantially in accordance with the provisions of the contract; (b) the contractor fails to comply within a reasonable time with a notice given by the supervisor requiring him to make good any neglect or failure to perform his obligations under the contract which seriously affects the proper and timely performance of the works; (c) the contractor refuses or neglects to carry out administrative orders given by the supervisor; (d) the contractor assigns the contract or sub-contracts without the authorization of the contracting authority; (e) the contractor becomes bankrupt or insolvent, or has a receiving order made against him, or compounds with his creditors, or carries on business under a receiver, trustee or manager for the benefit of his creditors, or goes into liquidation; (f) any adverse final judgment is made in respect of an offence relating to the professional conduct of the contractor; (g) any other legal disability hindering performance of the contract occurs; (h) any organizational modification occurs involving a change in the legal personality, nature or control of the contractor, unless such modification is recorded in an endorsement to the contract; (i) the contractor fails to provide the required guarantee or insurance, or if the person providing the earlier guarantee or insurance is not able to abide by his commitments. 64.3. Termination shall be without prejudice to any other rights or powers under the contract of the contracting authority and the contractor. The contracting authority may, thereafter, complete the works himself or conclude any other contract with a third party for the account of the contractor. The contractor's liability for delay in completion shall immediately cease when the contracting authority expels him from the site without prejudice to any liability thereunder that may have already ocurred. 64.4. The supervisor shall, upon the issue of the notice of termination of the contract, instruct the contractor to take immediate steps to bring the works to a close in a prompt and orderly manner and to reduce expenditure to a minimum. 64.5. The supervisor shall, as soon as is possible after termination, certify the value of the works and all sums due to the contractor as at the date of termination. 64.6. In the event of termination: (a) a report of work performed by the contractor shall be drawn up by the supervisor as soon as possible after inspection of the works, and inventory taken of temporary structures, materials, plant and equipment. The contractor shall be summoned to be present during the inspection and the taking of the inventory. The supervisor shall also draw up statements of emoluments still owed by the contractor to workers employed by him in relation to the contract and of sums owed by the contractor to the contracting authority; (b) the contracting authority shall have the option of acquiring in whole or in part temporary structures which have been approved by the supervisor, plant and materials specifically supplied or manufactured in connection with the execution of work under the contract; (c) the purchase price of the temporary structures, equipment, plant and materials referred to above shall not exceed the unpaid portion of the expenditure incurred by the contractor, such expenditure being limited to that required for the performance of the contract under normal conditions; (d) the contracting authority may purchase, at market prices, the materials and items supplied or ordered by the contractor and not already paid for by the contracting authority on such conditions as the supervisor considers appropriate. 64.7. The contracting authority shall not be obliged to make any further payments to the contractor until the works are completed, whereupon the contracting authority shall be entitled to recover from the contractor the extra costs, if any, of completing the works, or pay any balance due to the contractor prior to the termination of the contract. 64.8. If the contracting authority terminates the contract, it shall be entitled to recover from the contractor any loss it has suffered up to the maximum amount stated in the contract. If no maximum amount is stated, the contracting authority shall not be entitled to recover more than the part of the contract price corresponding to the value of that part of the works which cannot, by reason of the contractor's failure, be put to the intended use. 64.9. Where the termination is not due to an act or omission of the contractor, the latter shall be entitled to claim in addition to sums owing to him for work already performed, an indemnity for loss suffered. Article 65 Termination by the contractor 65.1. The contractor may, after giving 14 days notice to the contracting authority, terminate the contract if the contracting authority: (a) fails to pay the contractor the amounts due under any certificate issued by the supervisor after the expiry of the time limit stated in Article 53 (2); or (b) consistently fails to meet his obligations after repeated reminders; or (c) suspends the progress of the works or any part thereof for more than 180 days, for reasons not specified in the contract, or not due to the contractor's default. 65.2. Such termination shall be without prejudice to any other rights of the contracting authority or the contractor under the contract. Upon such termination, the contractor shall, subject to the law of the State of the contracting authority, be entitled to immediately remove his equipment from the site. 65.3. In the event of such termination, the contracting authority shall pay the contractor for any loss or damage the contractor may have suffered. Such additional payment shall not exceed a limit which has to be specified in the contract. Article 66 Force majeure 66.1. Neither party shall be considered to be in default or in breach of his obligations under the contract if the performance of such obligations is prevented by any circumstances of force majeure which arises after the date of notification of award or the date when the contract becomes effective, whichever is the earlier. 66.2. The term force majeure, as used herein shall mean acts of God, strikes, lock-outs or other industrial disturbances, acts of the public enemy, wars whether declared or not, blockades, insurrection, riots, epidemics, landslides, earthquakes, storms, lightning, floods, washouts, civil disturbances, explosions, and any other similar unforeseeable events, not within the control of either party and which by the exercise of due diligence neither party is able to overcome. 66.3. Notwithstanding the provisions of Articles 36 and 64, the contractor shall not be liable to forfeiture of his performance guarantee, liquidated damages or termination for default if, and to the extent that, his delay in performance or other failure to perform his obligations under the contract is the result of an event of force majeure. The contracting authority shall similarly not be liable, notwithstanding the provisions of Articles 53 and 65, to payment of interest on delayed payments, for non-performance or for termination by the contractor for default, if, and to the extent that, the contracting authority's delay or other failure to perform its obligations is the result of force majeure. 66.4. If either party considers that any circumstances of force majeure have occurred which may affect performance of his obligations, he shall promptly notify the other party and the supervisor, giving details of the nature, the probable duration and the likely effect of the circumstances. Unless otherwise directed by the supervisor in writing, the contractor shall continue to perform his obligations under the contract as far as is reasonably practicable, and shall seek all reasonable alternative means for performance of his obligations which are not prevented by the force majeure event. The contractor shall not put into effect such alternative means unless directed so to do by the supervisor. 66.5. If the contractor incurs additional costs in complying with the supervisor's directions or using alternative means under Article 66 (4), the amount thereof shall be certified by the supervisor. 66.6. If circumstances of force majeure have occurred and continue for a period of 180 days then, notwithstanding any extension of time for completion of the works that the contractor may be reason thereof have been granted, either party shall be entitled to serve upon the other 30 days' notice to terminate the contract. If, at the expiry of the period of 30 days, force majeure still continues, the contract shall terminate and, in consequence thereof under the law governing the contract, the parties shall be released from further performance of the contract. Article 67 Decease 67.1. Where the contractor is a natural person, the contract shall be automatically terminated if that person dies. However, the contracting authority shall examine any proposal made by the heirs or beneficiaries if they have notified their wish to continue the contract. The decision of the contracting authority shall be notified to those concerned within 30 days of receipt of such proposal. 67.2. Where the contractor consists of natural persons and one or more of them die, a report shall be agreed between the parties on the progress of the works and the contracting authority shall decide whether to terminate or continue the contract in accordance with the undertaking given by the survivors and by the heirs or beneficiaries, as the case may be. 67.3. In the cases provided for in Article 67 (1) and 67 (2), persons offering to continue to perform the contract shall notify the contracting authority thereof within 15 days of the date of decease. 67.4. Such persons shall be jointly and severally liable, or as otherwise stated in the special conditions, for the proper performance of the contract to the same extent as the deceased contractor. Continuation of the contract shall be subject to the rules relating to establishment of the guarantee provided for in Article 15. SETTLEMENT OF DISPUTES Article 68 Settlement of disputes 68.1. The contracting authority and the contractor shall make every effort to amicably settle disputes relating to the contract which may arise between them, or between the supervisor and the contractor. 68.2. The special conditions shall prescribe: (a) the procedure for the amicable settlement of disputes; (b) the time limits within which the amicable settlement procedure may be invoked after notification of the dispute to the other party and the maximum time limit within which such settlement may be reached, which may not exceed 120 days from the commencement of the adopted procedure; (c) the time limits for responding in writing to a request for amicable settlement or to other requests permitted during the course of that procedure and the consequence of failure to comply with those time limits. 68.3. The parties may agree to the settlement of the dispute by conciliation within a specific time limit by a third party after the amicable settlement procedure adopted has failed. 68.4. The amicable settlement or conciliation procedure adopted shall in all cases involve a procedure in which complaints and responses are notified to the other party. 68.5. In the absence of an amicable settlement or settlement by conciliation within the maximum time limits specified, the dispute shall: (a) in the case of a national contract, be settled in accordance with the national legislation of the State of the contracting authority; and (b) in the case of a transnational contract, be settled, either: i(i) if the parties to the contract so agree, in accordance with the national legislation of the State of the contracting authority or its established international practices; or (ii) by arbitration in accordance with the procedural rules adopted in accordance with the Convention.

Any supplier's drawings, documents, samples or models which the supervisor fails to approve, shall be forthwith modified to meet the requirements of the supervisor and resubmitted by the supplier for approval. 15.4. The supplier shall supply additional copies of approved drawings in the form and numbers stated in the contract or in subsequent administrative orders. 15.5. The approval of the drawings, documents, samples or models shall not relieve the supplier from any of his obligations under the contract. 15.6. The supervisor shall have the right at all reasonable times to inspect all contract drawings, documents, samples or models at the supplier's premises. 15.7. Before provisional acceptance of the supplies, the supplier shall supply operation and maintenance manuals together with drawings, which shall be in such detail as will enable the contracting authority to operate, maintain, adjust and repair all parts of the supplies. Unless otherwise stated in the special conditions, the manuals and drawings shall be in the language of the contract and in such forms and numbers as stated in the contract. The supplies shall not be considered to be completed for the purpose of provisional acceptance until such manuals and drawings have been supplied to the contracting authority. Article 16 Sufficiency of tender prices 16.1. Subject to any additional provisions which may be laid down in the special conditions, the supplier shall be deemed to have satisfied himself before submitting his tender as to the correctness and sufficiency of the tender and to have taken account of all that is required for the full and proper performance of the contract and to have included in his rates and prices all costs related to the supplies, in particular: (a) the costs of transport; (b) the costs of handling, packing, loading, unloading, transit, delivery, unpacking, checking, insurance, and other administrative costs in connection with the supplies. The packaging shall be the property of the contracting authority unless the special conditions provide otherwise; (c) the cost of documents relating to the supplies where such documents are required by the contracting authority; (d) performance and supervision of on-site assembly and/or start up of the delivered supplies; (e) furnishing of tools required for assembly and/or maintenance of the delivered supplies; (f) furnishing of detailed operation and maintenance manual for each unit of the delivered supplies, as specified in the contract; (g) supervision or maintenance and/or repair of the supplies, for a period of tine stated in the contract, provided that this service shall not relieve the supplier of any warranty obligations under the contract; and (h) training of the contracting authority's personnel, at the supplier's factory and/or elsewhere as specified in the contract. 16.2. Since the supplier is deemed to have determined his prices on the basis of his own calculations, operations and estimates, he shall carry out without additional charge any work which is the subject of any item whatsoever in his tender for which he neither indicates a unit price nor a firm sum. Article 17 Patents and licences Save where otherwise provided in the special conditions, the supplier shall indemnify the contracting authority and the supervisor against any claim resulting from the use, as specified in the contract, of patents, licences, drawings, designs, models, or brand or trade marks, except where such infringement results from compliance with the design or specifications provided by the contracting authority and/or the supervisor. COMMENCEMENT AND DELAYS Article 18 Commencement orders 18.1. The contracting authority shall fix the date on which performance of the contract is to commence, and advise the supplier either in the notification of award of contract or by administrative order issued by the supervisor. 18.2. The date for commencing performance shall be no later than 180 days following notification of award of contract unless agreed otherwise by the parties. Article 19 Period of performance 19.1. The period of performance shall commence on the date fixed in accordance with Article 18 (1) and shall be as stated in the contract, without prejudice to extensions of the period which may be granted under Article 20. 19.2. If provision is made for separate periods of performance for supply in separate lots, such periods shall not be aggregated in cases where one supplier is allocated more than one lot. Article 20 Extension of period of performance 20.1. The supplier may request an extension to the period of performance if he is or will be delayed in completing the contract by any of the following causes: (a) extra or additional supplies ordered by the contracting authority; (b) exceptional weather conditions in the State of the contracting authority which may affect installation or erection of the supplies; (c) physical obstructions or conditions which may affect delivery of the supplies, which could not reasonably have been foreseen by a competent supplier; (d) administrative orders affecting the date of completion other than those arising from the supplier's default; (e) failure of the contracting authority to fulfil his obligations under the contract; (f) any suspension of the delivery and/or installation of the supplies which is not due to the supplier's default; (g) force majeure; (h) any other causes referred to in these general conditions which are not due to the supplier's default. 20.2. The supplier shall, within 15 days of becoming aware that delay may occur, notify the supervisor of his intention to make a request for extension of the period of performance to which he considers himself entitled, and shall within 60 days thereafter, except where otherwise agreed between the supplier and the supervisor, deliver to the supervisor full and detailed particulars of the request, in order that such request may be investigated at the time. 20.3. The supervisor shall, by written notice to the supplier after due consultation with the contracting authority and where approriate, the supplier, grant such extension of the period of performance as may be justified, either prospectively or retrospectively or, inform the supplier that he is not entitled to an extension. Article 21 Delays in performance 21.1. If the supplier fails to deliver any or all of the goods or perform the services within the time period(s) specified in the contract, the contracting authority shall, without formal notice and without prejudice to his other remedies under the contract, be entitled to liquidated damages for every day or part thereof which shall elapse between the end of the period specified for performance, or extended performance under Article 20, and the actual date of completion, at the rate and up to the maximum amount specified in the special conditions. 21.2. If the contracting authority has become entitled to the maximum claim under Article 21.1 he may, after giving notice to the supplier: (a) seize the performance guarantee; and/or (b) terminate the contract; and (c) enter into a contract with a third party at the supplier's cost for the provision of the balance of the supplies. Article 22 Variations 22.1. The supervisor shall have power to order any variation to any part of the supplies necessary for the proper completion and/or functioning of the supplies. Such variations may include additions, omissions, substitutions, changes in quality, quantity, form, character, kind, as well as drawings, designs or specifications where the supplies are to be specifically manufactured for the contracting authority, method of shipment or packing, place of delivery, and in the specified sequence, method or timing of execution of the supplies. N° order for a variation shall have the effect of invalidating the contract, but the financial effect, if any, of all such variations shall be valued in accordance with Article 22 (5) and 22 (7). 22.2. N° variation shall be made except by administrative order, provided that: (a) if for any reason, the supervisor shall find it necessary to give an order orally, he shall as soon as possible thereafter confirm the order by an administrative order; (b) if the supplier shall confirm in writing an oral order given for the purpose of Article 22 (2) (a) and the confirmation shall not be contradicted in writing forthwith by the supervisor, an administrative order shall be deemed to have been issued for the variation; (c) an administrative order for variation shall not be required for increase or decrease in the quantity of any work where such increase or decrease is the result of the quantity exceeding or being less than that stated in the bill of quantities or price schedule. 22.3. Save as provided by Article 22 (2), prior to any administrative order for variation, the supervisor shall notify the supplier of the nature and form of such variation. As soon as possible, after receiving such notice, the supplier shall submit to the supervisor a proposal containing: (a) a description of the tasks, if any, to be performed or the measures to be taken and a programme for execution; and (b) any necessary modifications to the programme of performance or to any of the supplier's obligations under the contract; and (c) any adjustment to the contract price in accordance with the rules as set out in Article 22. 22.4. Following the receipt of the supplier's submission referred to in Article 22 (3), the supervisor shall, after due consultation with the contracting authority and, where appropriate, the supplier, decide as soon as possible whether or not the variation shall be carried out. If the supervisor decides that the variation shall be carried out he shall issue the administrative order stating that the variation shall be carried out at the prices and under the conditions given in the supplier's submission referred to in Article 22 (3) or as modified by the supervisor in accordance with Article 22 (5). 22.5. The prices for all variations ordered by the supervisor in accordance with Articles 22 (2) and 22 (4) shall be ascertained by the supervisor in accordance with the following principles: (a) where the task is of similar character and executed under similar conditions to an item priced in the bill of quantities or price schedule it shall be valued at such rates and prices contained therein; (b) where the task is not of a similar character or is not executed under similar conditions, the rates and prices in the contract shall be used as the basis for valuation so far as is reasonable, failing which, a fair valuation shall be made by the supervisor; (c) if the nature or amount of any variation relative to the nature or amount of the whole of the contract or to any part thereof shall be such that in the opinion of the supervisor any rate or price contained in the contract for any item of work is by reason of such variation rendered unreasonable, then the supervisor shall fix such rate or price as in the circumstances he shall think reasonable and proper; (d) where a variation is necessitated by default or breach of contract by the supplier, any additional cost attributable to such variation shall be borne by the supplier. 22.6. On receipt of the administrative order requesting the variation, the supplier shall proceed to carry out the variation and be bound by these general conditions in so doing as if such variation were stated in the contract. The supplies shall not be delayed pending the granting of any extension of time for completion or adjustment to the contract price. Where the order for a variation precedes the adjustment to the contract price, the supplier shall keep records of the costs of undertaking the variation and of time expended thereon. Such records shall be open to inspection by the supervisor at all reasonable times. 22.7. Where on provisional acceptance, an increase or reduction in the total value of supplies required under the contract resulting from an administrative order, or from some other circumstance which is not caused by the supplier's default, exceeds 15 % of the contract price, the supervisor shall, after consultation with the contracting authority and the supplier determine any additions to or reduction from the contract price as a consequence of the application of Article 22 (5). The sum so determined shall be based on the amount by which the increase or decrease in value of the supplies exceeds 15 %. The sum shall be notified by the supervisor to the contracting authority and the supplier and the contract price adjusted accordingly. Article 23 Suspension 23.1. The supervisor may, by administrative order, at any time, instruct the supplier to suspend: (a) progress of the manufacture of the supplies; or (b) delivery of supplies to the place of acceptance at the time specified for delivery in the performance programme or, if no time is specified, at the time appropriate for it to be delivered; or (c) the installation of the supplies which have been delivered to the place of acceptance. 23.2. The supplier shall, during suspension, protect and secure the supplies affected at the supplier's warehouse or elsewhere, against any deterioration, loss or damage to the extent possible and as instructed by the supervisor, even if the supplies have been delivered to the place of acceptance in accordance with the contract but whose installation has been suspended by the supervisor. 23.3. Additional expenses incurred in connection with such protective measure shall be added to the contract price. The supplier shall not be entitled to be paid any additional expenses if the suspension is: (a) otherwise provided for in the contract; or (b) necessary by reason of normal climatic conditions at the place of acceptance; or (c) necessary by reason of some default of the supplier; or (d) necessary for the safety or the proper execution of the contract or any part thereof insofar as such necessity does not arise from any act or default by the supervisor or the contracting authority. 23.4. The supplier shall not be entitled to such additions to the contract price unless he notifies the supervisor, within 30 days after receipt of the order to suspend progress or delivery, of his intention to make a claim for them. 23.5. The supervisor, after consultation with the contracting authority and the supplier, shall determine such extra payment and/or extension of the period of performance to be made to the supplier in respect of such claim as shall, in the opinion of the supervisor, be fair and reasonable. 23.6. If the period of suspension exceeds 180 days, and the suspension is not due to the supplier's default, the supplier may, by notice to the supervisor, request permission to proceed with the supplies within 30 days, or terminate the contract. MATERIALS AND WORKMANSHIP Article 24 Quality of supplies 24.1. The supplies must in all respects satisfy the technical specifications laid down in the special conditions and conform in all respects with the drawings, surveys, models, samples, patterns, and other requirements in the contract which shall be held at the disposal of the contracting authority or the supervisor for the purposes of identification throughout the period of performance. 24.2. Any preliminary technical acceptance stipulated in the special conditions shall be the subject of a request sent by the supplier to the supervisor. The request shall indicate the specification of the materials, items and samples submitted for such acceptance according to the contract, the lot number and the place where acceptance is to take place, as appropriate. The materials, items and samples specified in the request must be certified by the supervisor as meeting the requirements for such acceptance prior to their incorporation in the supplies. 24.3. Even if materials or items to be incorporated in the supplies or in the manufacture of components to be supplied have been technically accepted in this way, they may still be rejected and must be replaced immediately by the supplier if a further examination reveals defects or faults. The supplier may be given the opportunity to repair and make good materials and items which have been rejected, but such materials and items will be accepted for incorporation in the supplies only if they have been repaired and made good to the satisfaction of the supervisor. Article 25 Inspection and testing 25.1. The supplier shall ensure that the supplies are delivered to the place of acceptance in time to allow the supervisor to proceed with acceptance of the supplies. The supplier is deemed to have fully appreciated the difficulties which he might encounter in this respect, and he shall not be permitted to advance any grounds for delay in fulfilling his obligations. 25.2. The supervisor shall be entitled either by himself or his agent, from time to time, to inspect, examine, measure and test the components, materials and workmanship, and check the progress of preparation, fabrication or manufacture of anything being prepared, fabricated or manufactured for delivery under the contract in order to establish whether the components, materials and workmanship are of the requisite quality and quantity. This shall take place at the place of manufacture, fabrication or preparation or at the place of acceptance or at such other places as may be specified in the contract. 25.3. For the purposes of such tests and inspections, the supplier shall: (a) provide to the supervisor, temporarily and free of charge, such assistance, test samples or parts, machines, equipment, tools, labour, materials, drawings and production data as are normally required for inspection and testing; (b) agree, with the supervisor, on the time and place for tests; (c) provide access for the supervisor at all reasonable times to the place where the tests are to be carried out. 25.4. If the supervisor is not present on the date agreed for tests, the supplier may, unless otherwise instructed by the supervisor, proceed with the tests, which shall be deemed to have been made in the supervisor's presence. The supplier shall forthwith forward duly certified copies of the test results to the supervisor, who shall, if he has not attended the test, be bound by the test results. 25.5. When components and materials have passed the tests referred to in Article 25, the supervisor shall notify the supplier or endorse the supplier's certificate to that effect. 25.6. If the supervisor and the supplier disagree on the test results, each shall give a statement of his views to the other within 15 days after such disagreement arises. The supervisor or the supplier may require such tests to be repeated on the same terms and conditions or, if either party so requests, by an expert to be selected by common consent. All test reports shall be submitted to the supervisor who shall communicate the results of these tests without delay to the supplier. The results of the retesting shall be conclusive. The cost of retesting shall be borne by the party whose views are proved wrong by the retesting. 25.7. In the performance of his duties, the supervisor and all persons authorized by him shall disclose only to those persons who are entitled to know of it information which he has obtained by reason of his inspection and testing of the methods of manufacture and operation of the undertaking. Article 26 Property in the supplies 26.1. The special conditions may provide that the supplier, for the purpose of securing payment under Article 32 in respect of any part of the supplies before delivery to the place of acceptance, shall: (a) vest that part of the supplies in the contracting authority; or (b) make that part of the supplies subject to a lien in favour of the contracting authority; or (c) make that part of the supplies subject to any other arrangement regarding priority interest or security. 26.2. Upon termination of the contract before completion, the supplier shall deliver to the contracting authority any part of the supplies the property in which has vested in the contracting authority or been made subject to a lien by virtue of Article 26 (1). If he fails to do so the contracting authority may take such appropriate action as it deems fit in order to obtain possession of such supplies, and recover the cost of so doing from the supplier. PAYMENTS Article 27 General provisions 27.1. Payments shall be made in the national currency except as otherwise stipulated in the contract. 27.2. The administrative or technical conditions to which the payment of advances, interim and/or final payments made in accordance with Articles 28 to 36 are subject, shall be as stated in the special conditions. Article 28 Provisional price contracts 28.1. In exceptional cases, where all the prices cannot be predetermined, a provisional price contract may be awarded after consultation and agreement between the contracting authority and the supplier. The amount of the contract shall be determined initially on the basis of provisional prices and, after the conditions for performance of the contract are known, by the procedure specified in the special conditions. 28.2. The supplier shall supply such information as the contracting authority or the supervisor may reasonably require in respect of any matter relating to the contract for the purpose of the calculation. Where agreement cannot be reached on the valuation of the supplies, the amounts payable shall be determined by the supervisor. Article 29 Advances 29.1. Unless otherwise provided in the special conditions, advances shall be granted to the supplier, at his request, for operations connected with the provision of the supplies as a lump-sum advance. 29.2. Subject to the provisions of the special conditions, the total amount of the advances shall not exceed 60 % of the contract price. 29.3. N° advance shall be granted until: (a) the conclusion of the contract; (b) provision to the contracting authority by the supplier of the performance guarantee in accordance with Article 11; and (c) provision to the contracting authority by the supplier of a separate directly liable guarantee for the full amount of the advance by the institutions referred to in Article 11.3, which shall remain effective for at least 60 days after provisional acceptance of the supplies. 29.4. The supplier shall use the advance exclusively for operations connected with the provision of the supplies. Should the supplier misuse any portion of the advance, it shall become due and repayable immediately and no further advance payment shall be made to him. 29.5. Should the advance guarantee cease to be valid and the supplier fail to re-validate it, either a deduction equal to the amount of the advance may be made by the contracting authority from future payments due to the supplier under the contract, or the contracting authority may apply the provisions of Article 11 (6). 29.6. If the contract is terminated for any reason whatsoever, the guarantees securing the advances may be invoked forthwith in order to repay the balance of the advances still owed by the supplier, and the guarantor shall not delay payment or raise objection for any reason whatever. 29.7. The advance guarantee provided for in Article 29 shall not be released before provisional acceptance of the supplies but shall be released within 60 days thereafter. 29.8. Further conditions and procedures for granting and repaying advances shall be as laid down in the special conditions. Article 30 Retention sums 30.1. The sum which shall be retained from interim payments by way of guarantee to meet the supplier's obligations during the warranty period, and the detailed rules governing that guarantee, shall be as stipulated in the special conditions, provided that it shall in no case exceed 10 % of the contract price. 30.2. Subject to the approval of the contracting authority, the supplier may, if he so wishes, substitute, not later than the provisional acceptance of the supplies, these retention sums by a retention guarantee issued in accordance with Article 11 (3). 30.3. The sum retained or the retention guarantee shall be released within 90 days of the date of final acceptance of the supplies. Article 31 Revision of prices 31.1. Unless otherwise stipulated in the special conditions, and except as provided in Article 31 (4), contracts shall be at fixed prices which shall not be revised. 31.2. Where prices may be revised under the contract, such revision shall take into account variations in the prices of significant local or external elements which served as a basis for the calculation of the tender price, such as manpower, services, materials and supplies, as well as charges laid down by law or regulation. The detailed rules for the revision shall be as laid down in the special conditions. 31.3. Prices contained in the supplier's tender shall be deemed: (a) to have been arrived at on the basis of the conditions in force 30 days prior to the latest date fixed for submission of tenders or, in the case of direct agreement contracts, on the date of the contract; (b) to have taken account of the legislation and the relevant tax arrangements applicable at the reference date fixed in Article 31 (3) (a). 31.4. In the event of changes to, or introduction of, any national or State statute, ordinance, decree or other law, or any regulation or by-law of any local or other public authority, after the date stated in Article 31 (3) which causes a change in the contractual relationship between parties to the contract, the contracting authority and the supplier shall consult on how best to proceed further under the contract, and may as a result of such consultation decide: (a) to modify the contract; or (b) on payment of compensation for the resulting imbalance by one party to the other; or (c) to terminate the contract by mutual agreement. 31.5. In the event of a delay in the execution of the contract for which the supplier is responsible or at the end of the period of performance revised as necessary in accordance with the contract, there shall be no further revision of prices within the 30 days before provisional acceptance except for the application of new price indexation, if this is to the benefit of the contracting authority. Article 32 Interim payments 32.1. Unless otherwise specified in the special conditions, the supplier shall submit an application for interim payment to the supervisor at the end of each period referred to in Article 32 (7) in a form approved by the supervisor. The application shall include the following items, as applicable: (a) the estimated contract value of the supplies delivered up to the end of the period in question; (b) an amount reflecting any revision of prices pursuant to Article 31; (c) an amount to be withheld as retention sum under Article 30; (d) any credit and/or debit for the period in question in respect of supplies delivered under the contract, but not yet installed or commissioned in the amount and under the conditions set out in Article 32 (2); (e) any other sum to which the supplier may be entitled under the contract. 32.2. The supplier shall be entitled to such sums as the supervisor may consider proper in respect of supplies delivered under the contract, but not yet installed or commissioned, provided that: (a) the supplies conform to the specification of the contract and are set out in batches in a way that they may be recognized by the supervisor; (b) such supplies have been delivered to the place of acceptance, and are properly stored and protected against loss, damage or deterioration to the satisfaction of the supervisor; (c) the supplier's record of requirements, orders, receipts and use of goods and materials under the contract are kept in a form approved by the supervisor and such records are available for inspection by the supervisor; (d) the supplier submits with his statement, the estimated value of the supplies at the place of acceptance, together with such documents as may be required by the supervisor for the purpose of valuation of the supplies at the place of acceptance, together with such documents as may be required by the supervisor for the purpose of valuation of the supplies and providing evidence of ownership and payment therefor; and (e) where the special conditions so provide, ownership of the supplies shall be deemed to be vested in the contracting authority. 32.3. Approval by the supervisor of any interim payment certified by him in respect of goods and materials pursuant to Article 32 shall be without prejudice to the exercise of any power of the supervisor under the contract to reject any goods and materials which are not in accordance with the provisions of the contract. Where the special conditions so provide, upon any such rejection the property in the rejected goods and materials shall immediately revert to the supplier. 32.4. The supplier shall be responsible for any loss or damage to and for the cost of storing, handling of and removing from the place of acceptance, such goods and materials which have been rejected and shall effect such additional insurance as may be necessary to cover the risk of such loss or damage from any cause. 32.5. Within 30 days of receipt of the said application for interim payment, it shall be approved or amended in such manner that, in the supervisor's opinion, it reflects the amount due to the supplier in accordance with the contract. In cases where there is a difference of opinion as to the value of an item, the supervisor's view shall prevail. On determination of the amount due to the supplier, the supervisor shall issue to the contracting authority and the supplier, an interim payment certificate for the amount due to the supplier and shall inform the supplier of the supplies for which payment is being made. 32.6. The supervisor may, by an interim payment certificate, make any corrections or modifications to any previous certificate issued by him and shall have power to modify the valuation in or withhold the issuing of any interim payment certificate if the contract, or any part thereof, has not been executed to his satisfaction. 32.7. The frequency of interim payments shall be laid down in the special conditions in accordance with the characteristics of the supplies. 32.8. The special conditions may require certain interim payments to be fully secured by a guarantee approved in accordance with Article 11. Article 33 Final statement of account 33.1. Not later than 60 days after the issue of the final acceptance certificate referred to in Article 41, the supplier shall submit to the supervisor a draft final statement of account with supporting documents showing in detail the value of the supplies provided in accordance with the contract, together with all further sums which the supplier considers to be due to him under the contract in order to enable the supervisor to prepare the final statement of account. The special conditions may, however, in accordance with Article 33 (6) state that the draft final statement of account and further proceedings related thereto, be dealt with before the issue of the provisional acceptance certificate. 33.2. Within 60 days after receipt of this draft final statement of account and of all information reasonably required for its verification, the supervisor shall prepare the final statement of account, which determines: (a) the amount which in his opinion is finally due under the contract; and (b) after establishing the amounts previously paid by the contracting authority and all sums to which the contracting authority is entitled under the contract, the balance, if any, due from the contracting authority to the supplier, or from the supplier to the contracting authority, as the case may be. 33.3. The supervisor shall issue to the contracting authority or its duly authorized representative, and to the supplier, the final statement of account showing the final amount to which the supplier is entitled under the contract. The contracting authority or its duly authorized representative and the supplier shall sign the final statement of account as an acknowledgement of the full and final value of the supplies provided under the contract and shall promptly submit the signed copy to the supervisor. However, the final statement of account shall not include amounts in dispute which are the subject of negotiations, conciliation, arbitration or litigation. 33.4. The final statement of account signed by the supplier shall constitute a written discharge of the contracting authority confirming that the total of the final statement of account represents full and final settlement of all monies due to the supplier under the contract, other than those amounts which are the subject of amicable settlement, arbitration or litigation. However, such discharge shall become effective only after any payment due in accordance with the final statement of account has been made and the performance guarantee referred to in Article 11, has been returned to the supplier. 33.5. The contracting authority shall not be liable to the supplier for any matter or thing whatsoever arising out of, or in connection with, the contract or provision of the supplies, unless the supplier shall have included a claim in respect thereof in his draft final statement of account. 33.6. The provisions of Article 33 may be varied by the special conditions having regard to the practices in the State of the contracting authority. Article 34 Payment to third parties 34.1. All orders for payment to third parties may be carried out only after an assignment made in accordance with Article 6. The assignment shall be notified to the contracting authority. 34.2. Notification of beneficiaries of the assignment shall be the sole responsibility of the supplier. 34.3. In the event of a legally binding attachment of the property of the supplier affecting payments due to him under the contract, and without prejudice to the time limit laid down in Article 35, the contracting authority shall have 30 days, starting from the day when it receives notification of the definitive lifting of the obstacle to payment, to resume payments to the supplier. Article 35 Delayed payments 35.1. Payment to the supplier of the amounts due under each of the interim payment certificates and the final statement of account issued by the supervisor shall be made by the contracting authority within 90 days of such certificate or statement being delivered to the contracting authority. If the period laid down for payment has been exceeded, the supplier shall qualify for interest calculated pro rata on the basis of the number of days delay at the rate specified in the special conditions subject to a maximum period, also specified therein. The supplier shall be entitled to such payment without prejudice to any other right or remedy under the contract. In the case of the final statement of account, the interest for the delayed payment shall be calculated on a daily basis at the rate specified in the special conditions. 35.2. Any default in payment of more than 120 days from the expiry of the period laid down in Article 35 (1) shall entitle the supplier either not to perform the contract or to terminate it. Article 36 Payments in foreign currency Where under the contract the supplier is entitled to payments in foreign currency, the rates of exchange for calculating the payments shall be those prevailing, as determined by the Central Bank of the State of the contracting authority, 30 days prior to the latest date fixed for the submission of tenders for the contract. Such rates of exchange shall not be varied. ACCEPTANCE AND MAINTENANCE Article 37 Delivery 37.1. The supplier shall deliver the supplies in accordance with the terms specified in the contract and the supplies shall remain at the risk of the supplier until provisional acceptance. 37.2. The supplier shall provide such packaging of the supplies as is required to prevent their damage or deterioration in transit to their final destination as indicated in the contract. The packaging shall be sufficient to withstand, without limitation, rough handling, exposure to extreme temperatures, salt and precipitation during transit and open storage. Package size and weights shall take into consideration, where appropriate, the remoteness of the final destination of the supplies, and the possible absence of heavy handling facilities at all points in transit. 37.3. The packaging, marking and documentation within and outside the packages shall comply with such special requirements as shall be expressly provided for in the contract, subject to any variations subsequently ordered by the supervisor. 37.4. N° supplies shall be shipped or delivered to the place of acceptance until a confirmation in writing has been obtained by the supplier from the supervisor that the supplies may be delivered. The supplier shall be responsible for the delivery at the place of acceptance of all supplies and supplier's equipment required for the purpose of the contract. 37.5. Each delivery must be accompanied by a statement drawn up by the supplier. This statement, the form of which shall be as prescribed by the special conditions, shall contain, in particular: - the date of delivery, - the reference number of the contract, - the identification of the supplier, - particulars of the goods supplied and, where appropriate, details of how they were divided for packing. 37.6. Each package must be clearly marked with its order number as shown on the statement referred to in Article 37 (5); in the absence of indications to the contrary, this statement shall contain a list of its contents. 37.7. Delivery shall be deemed to have been made when there is written evidence available to both parties that delivery of the supplies has taken place in accordance with the terms of the contract and the invoice(s) and all such other documentation as specified in the special conditions, have been submitted to the contracting authority. Where the supplies are delivered to an establishment of the contracting authority, the latter shall bear the responsibility of bailee, in accordance with the requirements of the law of the contract, during the time which elapses between delivery for storage and acceptance. 37.8.

Article 38 Verification operations 38.1. The supplies shall not be accepted until the prescribed verifications and tests have been carried out at the expense of the supplier. The inspections and tests may be conducted at the point of delivery and/or at the final destination of the goods. 38.2. The supervisor shall, during the progress of the delivery of the supplies and before the supplies are taken over, have the power to order or decide: (a) the removal from the place of acceptance, within such time or times as may be specified in the order, of any supplies which, in the opinion of the supervisor, are not in accordance with the contract; (b) the substitution by proper and suitable supplies; (c) the removal and proper re-installation, notwithstanding any previous test thereof or interim payment therefor, of any installation which in respect of materials, workmanship or design by the supplier for which he is responsible, is not, in the opinion of the supervisor, in accordance with the contract; (d) that any work done or goods supplied or materials used by the supplier is or are not in accordance with the contract, or that the supplies or any portion thereof do not fulfil the requirements of the contract. 38.3. The supplier shall, with all speed and at his own expense, make good the defects so specified. In case of default on the part of the supplier in carrying out such order, the contracting authority shall be entitled to employ other persons to carry out the orders and all expenses consequent thereon or incidental thereto shall be recoverable from the supplier by the contracting authority, or may be deducted by the contracting authority from any monies due or which may become due to the supplier. 38.4. Supplies which are not of the required quality shall be rejected. A special mark may be applied to the rejected supplies. This shall not be such as to alter them or affect their commercial value. Rejected supplies shall be removed by the supplier from the place of acceptance, if the supervisor so requires, within a period which the supervisor shall specify, failing which they shall be removed as of right at the expense and risk of the supplier. Any work incorporating rejected materials shall be rejected. 38.5. The provisions of Article 38 shall not affect the right of the contracting authority to claim under Article 21, nor shall it in any way release the supplier from any warranty or other obligations under the contract. Article 39 Provisional acceptance 39.1. The supplies shall be taken over by the contracting authority when they have been delivered in accordance with the contract, have satisfactorily passed the required tests, or have been commissioned, as the case may be, and a certificate of provisional acceptance has been issued or is deemed to have been issued. 39.2. The supplier may apply, by notice to the supervisor, for a certificate of provisional acceptance not earlier than 15 days before the supplies, in the supplier's opinion, are complete and ready for provisional acceptance. The supervisor shall within 30 days after the receipt of the supplier's application either: (a) issue the certificate of provisional acceptance to the supplier with a copy to the contracting authority stating, where appropriate, his reservations and, inter alia, the date on which, in his opinion, the supplies were completed in accordance with the contract and ready for provisional acceptance; or (b) reject the application giving his reasons and specifying the actions which, in his opinion, are required of the supplier for the certificate to be issued. 39.3. Should exceptional circumstances make it impossible to proceed with the acceptance of the supplies during the period fixed for provisional or final acceptance, a statement certifying such impossibility shall be drawn up by the supervisor after consultation, where possible, with the supplier. The certificate of acceptance or rejection shall be drawn up within 30 days following the date on which such impossibility ceases to exist. The supplier shall not invoke these circumstances in order to avoid the obligation of presenting the supplies in a state suitable for acceptance. 39.4. If the supervisor fails either to issue the certificate of provisional acceptance or to reject the supplies within the period of 30 days, he shall be deemed to have issued the certificate on the last day of that period. The certificate of provisional acceptance shall not be deemed to be an admission that the supplies have been delivered in every respect. If the supplies are divided by the contract into lots, the supplier shall be entitled to apply for separate certificates for each of the lots. 39.5. Upon provisional acceptance of the supplies, the supplier shall dismantle and remove temporary structures as well as materials no longer required for use in connection with the performance of the contract. He shall also remove any litter or obstruction and redress any change in the condition of the place of acceptance as required by the contract. Article 40 Warranty obligations 40.1. The supplier shall warrant that the supplies are new, unused, of the most recent models and incorporate all recent improvements in design and materials, unless otherwise provided in the contract. The supplier shall further warrant that all supplies shall have no defect arising from design, materials or workmanship, except insofar as the design or materials are required by the specifications, or from any act or omission of the contracting authority, that may develop under use of the supplies in the conditions obtaining in the State of the contracting authority. 40.2. Unless otherwise specified in the special conditions, this warranty shall remain valid for 360 days after the supplies or any portion thereof, as the case may be, have been delivered and commissioned at the final destination indicated in the contract, or for 540 days after the date of shipment from the port of loading in the country of origin, whichever period ends earlier. The obligation to maintain the supplies shall be subject to any stipulations in the special conditions and specifications which shall determine the period and conditions thereof. 40.3. The supplier shall be responsible for making good any defect in or damage to any part of the supplies which may appear or occur during the warranty period, or within 30 days after its expiration and which arise either: (a) from the use of defective materials, faulty workmanship or design of the supplier; or (b) from any act or omission of the supplier during the warranty period; or (c) in the course of an inspection made by, or on behalf of, the contracting authority. 40.4. The supplier shall at his own cost make good the defect or damage as soon as practicable. The warranty period for all items replaced or repaired shall recommence from the date when the replacement or repair was made to the satisfaction of the supervisor. If the contract provides for partial acceptance, the warranty period shall be extended only for the part of the supplies affected by the replacement or repair. 40.5. If any such defects appear or such damage occurs during the period referred to in Article 40 (3), the contracting authority or the supervisor shall notify the supplier. If the supplier fails to remedy a defect or damage within the time limit stipulated in the notification, the contracting authority may: (a) remedy the defect or the damage itself, or employ someone else to carry out the work at the supplier's risk and cost, in which case the costs incurred by the contracting authority shall be deducted from monies due to or from guarantees held against the supplier or from both; or (b) terminate the contract. 40.6. In case of emergency where the supplier cannot be reached immediately or, having been reached, is unable to take the measures required, the contracting authority or the supervisor may have the work carried out at the expense of the supplier. The contracting authority or the supervisor shall as soon as practicable inform the supplier of the action taken. Article 41 After sales service An after sales service, if required by the contract, shall be provided in accordance with the details stipulated in the special conditions. The supplier shall undertake to carry out or have carried out the maintenance and repair of supplies and to provide a rapid supply of spare parts. The special conditions may specify that the supplier shall be required to provide any or all of the following materials, notifications and documents pertaining to spare parts manufactured or distributed by the supplier: (a) such spare parts as the contracting authority may elect to purchase from the supplier, provided that this election shall not relieve the supplier of any warranty obligations under the contract; and (b) in the event of termination of production of the spare parts advance notification to the contracting authority to procure needed requirements; and following such termination, furnishing at no cost to the contracting authority, the blueprints, drawings and specifications of the spare parts, if and when requested. Article 42 Final acceptance 42.1. Upon the expiration of the warranty period or where there is more than one such period, upon the expiration of the latest period and when all defects or damage have been rectified, the supervisor shall issue to the supplier a final acceptance certificate and a copy thereof to the contracting authority stating the date on which the supplier completed his obligations under the contract to the supervisor's satisfaction. The final acceptance certificate shall be given by the supervisor within 30 days after the expiration of the warranty period, or as soon thereafter as any rectifications instructed, pursuant to Article 40, have been completed to the satisfaction of the supervisor. 42.2. The contract shall not be considered to be fully executed until the final acceptance certificate has been signed by the supervisor and delivered to the contracting authority, with a copy to the contractor. 42.3. Notwithstanding the issue of the final acceptance certificate, the supplier and the contracting authority shall remain liable for the fulfilment of any obligation incurred under the contract prior to the issue of the final acceptance certificate, which remains unperformed at the time such final acceptance certificate is issued. The nature and extent of any such obligation shall be determined by reference to the provisions of the contract. BREACH OF CONTRACT AND TERMINATION Article 43 Breach of contract 43.1. Either party commits a breach of contract where he fails to discharge any of his obligations under the contract. 43.2. Where a breach of contract occurs, the party injured by the breach shall be entitled to the following remedies: (a) damages; and/or (b) termination of the contract. 43.3. Damages may be: (a) general damages; or (b) liquidated damages. 43.4. In any case where the contracting authority is entitled to damages, it may deduct such damages from any sums due to the supplier or from the appropriate guarantee. Article 44 Termination by the contracting authority 44.1. The contracting authority may, at any time and with immediate effect, terminate the contract, except as provided for in Article 44 (2). 44.2. Except as otherwise provided in these general conditions, the contracting authority may, after giving seven days notice to the supplier, terminate the contract in any of the following cases where: (a) the supplier fails to provide the supplies in strict accordance with the provisions of the contract; (b) the supplier fails to comply within a reasonable time with a notice given by the supervisor requiring him to make good any neglect or failure to perform his obligations under the contract which seriously affect the proper and timely performance of the contract; (c) the supplier refuses or neglects to carry out administrative orders given by the supervisor; (d) the supplier assigns the contract or sub-contracts without the authorization of the contracting authority; (e) the supplier becomes bankrupt or insolvent, or has a receiving order made against him, or compounds with his creditors, or carries on business under a receiver, trustee or manager for the benefit of his creditors, or goes into liquidation; (f) any adverse final judgment is made in respect of an offence relating to the professional conduct of the supplier; (g) any other legal disability hindering performance of the contract occurs; (h) any organizational modification occurs involving a change in the legal personality, nature or control of the supplier, unless such modification is recorded in an endorsement to the contract; (i) the supplier fails to provide the required guarantee or insurance, or if the person providing the earlier guarantee or insurance is not able to abide by his commitments. 44.3. Termination shall be without prejudice to any other rights or powers under the contract of the contracting authority and the supplier. The contracting authority may, thereafter, conclude any other contract with a third party for the account of the supplier. The supplier's liability for delay in completion shall immediately cease upon termination without prejudice to any liability thereunder that may have already occurred. 44.4. The supervisor shall, upon the issue of the notice of termination of the contract, instruct the supplier to take immediate steps to bring the execution of the supplies to a close in a prompt and orderly manner and to reduce expenditure to a minimum. 44.5. The supervisor shall, as soon as possible after termination, certify the value of the supplies and all sums due to the supplier as at the date of termination. 44.6. In the event of termination: (a) the supplier or his representatives being present or duly summoned, a report of supplies delivered and the work performed shall be drawn up by the supervisor as soon as possible, and inventories taken of the materials supplied and unused. A statement shall also be drawn up of sums owed by the supplier to the contracting authority; (b) the contracting authority may purchase, at market prices, the materials and items supplied or ordered by the supplier and not already paid for by the contracting authority on such conditions as the supervisor considers appropriate. 44.7. The contracting authority shall not be obliged to make any further payments to the supplier until the supplies are completed, whereupon the contracting authority shall be entitled to recover from the supplier the extra costs, if any, of providing the supplies, or shall pay any balance due to the supplier prior to termination of the contract. 44.8. If the contracting authority terminates the contract, it shall be entitled to recover from the supplier any loss it has suffered up to the maximum amount stated in the contract. If no maximum amount is stated, the contracting authority shall not be entitled to recover more than the part of the contract price corresponding to the value of that part of the supplies which cannot, by reason of the supplier's failure, be put to the intended use. 44.9. Where the termination is not due to an act or omission of the supplier, the latter shall be entitled to claim, in addition to sums owing to him for work already performed, an indemnity for loss suffered. Article 45 Termination by the supplier 45.1. The supplier may, giving 14 days notice to the contracting authority, terminate the contract if the contracting authority: (a) fails to pay the supplier the amounts due under any certificate issued by the supervisor after the expiry of the time limit stated in Article 35 (2); (b) consistently fails to meet his obligations after repeated reminders; or (c) suspends the progress of the delivery of the supplies, or any part thereof, for more than 180 days, for reasons not specified in the contract, or not due to the supplier's default; 45.2. Such termination shall be without prejudice to any other rights of the contracting authority or the supplier acquired under the contract. 45.3. In the event of such termination, the contracting authority shall pay the supplier for any loss or damage the supplier may have suffered. Such additional payment shall not exceed a limit which has to be specified in the contract. Article 46 Force majeure 46.1. Neither party shall be considered to be in default or in breach of his obligations under the contract if the performance of such obligations is prevented by any circumstances of force majeure which arises after the date of notification of award or the date when the contract becomes effective, whichever is the earlier. 46.2. The term force majeure, as used herein shall mean acts of God, strikes, lock-outs or other industrial disturbances, acts of the public enemy, wars whether declared or not, blockades, insurrection, riots, epidemics, landslides, earthquakes, storms, lightning, floods, washouts, civil disturbances, explosions, and any other similar unforeseeable events, not within the control of either party and which by the exercise of due diligence neither party is able to overcome. 46.3. Notwithstanding the provisions of Articles 21 and 44, the supplier shall not be liable to forfeiture of his performance guarantee, liquidated damages or termination for default if, and to the extent that, his delay in performance or other failure to perform his obligations under the contract is the result of an event of force majeure. The contracting authority shall similarly not be liable, notwithstanding the provisions of Articles 35 and 45, to payment of interest on delayed payments, for non-performance or for termination by the supplier for default, if, and to the extent that, the contracting authority's delay or other failure to perform its obligations is the result of force majeure. 46.4. If either party considers that any circumstances of force majeure have occurred which may affect performance of his obligations, he shall promptly notify the other party and the supervisor, giving details of the nature, the probable duration and the likely effect of the circumstances. Unless otherwise directed by the supervisor in writing, the supplier shall continue to perform his obligations under the contract as far as is reasonably practicable, and shall seek all reasonable alternative means for performance of his obligations which are not prevented by the force majeure event. The supplier shall not put into effect such alternative means unless directed so to do by the supervisor. 46.5. If the supplier incurs additional costs in complying with the supervisor's directions or using alternative means under Article 46 (4) the amount thereof shall be certified by the supervisor. 46.6. If circumstances of force majeure have occurred and continue for a period of 180 days then, notwithstanding any extension of time for completion of the contract that the supplier may by reason thereof have been granted, either party shall be entitled to serve upon the other 30 days' notice to terminate the contract. If at the expiry of the period of 30 days, force majeure still continues, the contract shall terminate and, in consequence thereof under the law governing the contract, the parties shall be released from further performance of the contract. Article 47 Decease 47.1. Where the supplier is a natural person, the contract shall be automatically terminated if that person dies. However, the contracting authority shall examine any proposal made by the heirs or beneficiaries if they have notified their wish to continue the contract. The decision of the contracting authority shall be notified to those concerned within 30 days of receipt of such proposal. 47.2. Where the supplier consists of natural persons and one or more of them die, a report shall be agreed between the parties on the progress of the contract and the contracting authority shall decide whether to terminate or continue the contract in accordance with the undertaking given by the survivors and by the heirs or beneficiaries, as the case may be. 47.3. In the cases provided for in Articles 47 (1) and 47 (2) persons offering to continue to perform the contract shall notify the contracting authority thereof within 15 days of the date of decease. 47.4. Such persons shall be jointly and severally liable, or as otherwise stated in the special conditions for the proper performance of the contract to the same extent as the original supplier. Continuation of the contract shall be subject to the rules relating to establishment of the guarantee provided for in Article 11. SETTLEMENT OF DISPUTES Article 48 Settlement of disputes 48.1.

The special conditions shall prescribe: (a) the procedure for the amicable settlement of disputes; (b) the time limits within which the amicable settlement procedure may be invoked after the time that the dispute is notified to the other party and the maximum time limit within which such settlement may be reached, which may not exceed 120 days from the commencement of the adopted procedure; (c) the time limits for responding in writing to a request for amicable settlement or to other requests permitted during the course of that procedure and the consequences of failure to comply with those time limits. 48.3. The parties may agree to the settlement of the dispute by conciliation within a specific time limit by a third party after the amicable settlement procedure adopted has failed. 48.4. The amicable settlement or conciliation procedure adopted shall in all cases involve a procedure in which complaints and responses are notified to the other party. 48.5. In the absence of an amicable settlement or settlement by conciliation within the maximum time limits specified, the dispute shall: (a) in the case of a national contract, be settled in accordance with the national legislation of the State of the contracting authority; and (b) in the case of a transnational contract, be settled, either: i(i) if the parties to the contract so agree, in accordance with the national legislation of the State of the contracting authority or its established international practices; or (ii) by arbitration in accordance with the procedual rules adopted in accordance with the Convention.
