(b) where there is a discrepancy between the unit rate and the

21

line item total resulting from multiplying the unit rate by the quantity, the unit rate as quoted shall govern, unless in the opinion of the Contracting Agency there is an obviously gross misplacement of the decimal point in the unit rate, in which case the line item total as quoted shall govern, and the unit rate shall be corrected.

28.2 The amount stated in the Bid shall be adjusted by the Contracting Agency in accordance with the above procedure for the correction of errors and, with the concurrence of the Bidder, shall be considered as binding upon the Bidder. If the Bidder does not accept the corrected amount, the Bid shall be rejected, and the Bid Security may be forfeited or the Bid- Validity Declaration executed in accordance with ITB Sub-Clause 17.5 (b).

29. Currency for Bid Evaluation

29.1 Bids shall be evaluated as quoted in the currency of the Contracting Agency’s Country in accordance with ITB Sub-Clause 15.1, unless a Bidder has used different exchange rates than those prescribed in ITB Sub-Clause 15.2, in which case the Bid shall be first converted into the amounts payable in different currencies using the rates quoted in the Bid and then reconverted to the currency of the Contracting Agency’s country using the exchange rates prescribed in ITB Sub-Clause 15.2.

(b) excluding provisional sums and the provision, if any, for contingencies in the Bill of Quantities, but including Daywork, where priced competitively;

(c) making an appropriate adjustment for any other acceptable variations, deviations, or alternative offers submitted in accordance with ITB Clause 18; and

(d) making appropriate adjustments to reflect discounts or other price modifications offered in accordance with ITB Sub-Clause 23.5.

30.3 The Contracting Agency reserves the right to accept or reject any variation, deviation, or alternative offer. Variations, deviations,

22

and alternative offers and other factors which are in excess of the requirements of the Bidding Documents or otherwise result in unsolicited benefits for the Contracting Agency shall not be taken into account in Bid evaluation.

successful Bidder’s, signing of the Agreement and furnishing of the Performance Security pursuant to ITB Clause 35.1, the Contracting Agency shall promptly notify the name of the winning bidder to each unsuccessful bidder and shall discharge the Bid Securities of the unsuccessful bidders pursuant to ITB Clause 17.4.

Section III. Eligible Countries

Eligibility for the Provision of Goods, Works and Services in Bank-Financed Procurement

Note: The expression “Bank” used in these documents includes the IDB, MIF and any other fund it administers. Depending on the financing source, the user must select one of the following 2 options for item number 1). The financing can come from the IDB, the Multilateral Investment Fund (MIF) or, occasionally, contracts may be financed out of special funds which further restricts eligibility criteria to a particular group of member countries. When the last option is selected, the eligibility criteria should be mentioned therein: ------------------------------------------------ 1) List of Member Countries when the Inter-American Development Bank is financing: a) Borrower Countries:

(i) Argentina, Bahamas, Barbados, Belize, Bolivia, Brazil, Colombia, Costa Rica, Chile, Dominican Republic, Ecuador, El Salvador, Guatemala, Guyana, Haiti, Honduras, Jamaica, Mexico, Nicaragua, Panama, Paraguay, Peru, Suriname, Trinidad & Tobago, Uruguay and Venezuela.

b) Non Borrower Countries

(ii) Austria, Belgium, Canada, China, Croatia, Denmark, Finland, France, Germany, Israel, Italy, Japan, Netherlands, Norway, People’s Republic of China, Portugal, Republic of Korea, Slovenia, Spain, Sweden, Switzerland, United Kingdom and United States.

----------------------------------------------

1) List of Countries when a Fund administered by the Bank is financing (Include the list of countries)] 2) Nationality and origin of Goods and Services Criteria These policy provisions make it necessary to establish criteria to determine: a) the nationality of the firms and individuals eligible to bid or participate in a bank-financed contract and b) the country of origin of goods, and services. For these determinations, the following criteria shall be used:

32

A) Nationality

a) An individual is considered to be a national of a member country of the Bank if he or she meets either of the following requirements:

.

i. is a citizen of a member country; or

ii. has established his/her domicile in a member country as a “bona fide” resident and is legally entitled to work in the country of domicile.

b) A firm is considered to have the nationality of a member country if it meets the two following requirements:

i. is legally constituted or incorporated under the laws of a member country of the Bank; and

ii. more than fifty percent (50%) of the firm’s capital is owned by individuals or firms from member countries of the Bank.

All members of a JVCA and all subcontractors must meet the nationality criteria set forth above.

B) Origin of Goods. Goods have their origin in a member country of the Bank if they have been mined, grown, harvested, or produced in a member country of the Bank. A good has been produced when through manufacture, processing or assembly another commercially recognized article results that differs substantially in its basic characteristics, function or purpose of utility from its parts or components. For a good consisting of several individual components that need to be interconnected (either by the supplier, the purchaser or by a third party) to make the good operative and regardless of the complexity of the interconnection, the Bank considers that such good is eligible for financing if the assembly of the components took place in a member country, regardless of the origin of the components. When the good is a set of several individual goods that are normally packaged and sold commercially as a single unit, the good is considered to originate in the country where the set was packaged and shipped to the purchaser. For purpose of origin, goods labeled “made in the European Union” shall be eligible without the need to identify the corresponding specific country of the European Union.

The origin of materials, parts or components of the goods or the nationality of the firm that produces, assembles, distributes or sells the goods, does not determine the origin of the goods.

33

The country of origin of services is that of the individual or firm providing the services as determined under the nationality criteria set forth above. These criteria apply to services ancillary to the supply of goods (such as transportation, insurance, erection, assembly, etc.), to construction services and to consulting services.

C) Origin of Services.

notify the Contractor of any Defects that are found. Such

55

checking shall not affect the Contractor’s responsibilities. The Project Manager may instruct the Contractor to search for a Defect and to uncover and test any work that the Project Manager considers may have a Defect.

34. Tests 34.1 If the Project Manager instructs the Contractor to carry out a test not specified in the Specification to check whether any work has a Defect and the test shows that it does, the Contractor shall pay for the test and any samples. If there is no Defect, the test shall be a Compensation Event.

35. Correction of Defects

35.1 The Project Manager shall give notice to the Contractor of any Defects before the end of the Defects Liability Period, which begins at Completion, and is defined in the SCC. The Defects Liability Period shall be extended for as long as Defects remain to be corrected.

36. Uncorrected Defects

36.1 If the Contractor has not corrected a Defect within the time specified in the Project Manager’s notice, the Project Manager shall assess the cost of having the Defect corrected, and the Contractor shall pay this amount.

D. Cost Control 37. Bill of

Quantities 37.1 The Bill of Quantities shall contain items for the construction,

installation, testing, and commissioning work to be done by the Contractor.

37.2 The Bill of Quantities is used to calculate the Contract Price. The Contractor is paid for the quantity of the work done at the rate in the Bill of Quantities for each item.

38. Changes in the Quantities

38.1 If the final quantity of the work done differs from the quantity in the Bill of Quantities for the particular item by more than 25 percent, provided the change exceeds 1 percent of the Initial Contract Price, the Project Manager shall adjust the rate to allow for the change.

38.2 The Project Manager shall not adjust rates from changes in quantities if thereby the Initial Contract Price is exceeded by more than 15 percent, except with the prior approval of the Contracting Agency.

56

38.3 If requested by the Project Manager, the Contractor shall provide the Project Manager with a detailed cost breakdown of any rate in the Bill of Quantities.

39. Variations 39.1 All Variations shall be included in updated Programs produced by the Contractor.

40. Payments for Variations

40.1 The Contractor shall provide the Project Manager with a quotation for carrying out the Variation when requested to do so by the Project Manager. The Project Manager shall assess the quotation, which shall be given within seven (7) days of the request or within any longer period stated by the Project Manager, before the Variation is ordered.

40.2 If the work in the Variation corresponds with an item description in the Bill of Quantities and if, in the opinion of the Project Manager, the quantity of work above the limit stated in Sub-Clause 38.1 or the timing of its execution do not cause the cost per unit of quantity to change, the rate in the Bill of Quantities shall be used to calculate the value of the Variation. If the cost per unit of quantity changes, or if the nature or timing of the work in the Variation does not correspond with items in the Bill of Quantities, the quotation by the Contractor shall be in the form of new rates for the relevant items of work.

40.3 If the Contractor’s quotation is unreasonable, the Project Manager may order the Variation and make a change to the Contract Price, which shall be based on the Project Manager’s own forecast of the effects of the Variation on the Contractor’s costs.

40.4 If the Project Manager decides that the urgency of varying the work would prevent a quotation being given and considered without delaying the work, no quotation shall be given and the Variation shall be treated as a Compensation Event.

40.5 The Contractor shall not be entitled to additional payment for costs that could have been avoided by giving early warning.

41. Cash Flow Forecasts

41.1 When the Program is updated, the Contractor shall provide the Project Manager with an updated cash flow forecast. The cash flow forecast shall include different currencies, as defined in the Contract, converted as necessary using the Contract exchange rates.

42. Payment Certificates

42.1 The Contractor shall submit to the Project Manager monthly statements of the estimated value of the work executed less the cumulative amount certified previously.

57

42.2 The Project Manager shall check the Contractor’s monthly statement and certify the amount to be paid to the Contractor.

42.3 The value of work executed shall be determined by the Project Manager.

42.4 The value of work executed shall comprise the value of the quantities of the items in the Bill of Quantities that have been completed.

42.5 The value of work executed shall include the valuation of Variations and Compensation Events.

42.6 The Project Manager may exclude any item certified in a previous certificate or reduce the proportion of any item previously certified in any certificate in the light of later information.

43. Payments 43.1 Payments shall be adjusted for deductions for advance payments and retention. The Contracting Agency shall pay the Contractor the amounts certified by the Project Manager within 28 days of the date of each certificate. If the Contracting Agency makes a late payment, the Contractor shall be paid interest on the late payment in the next payment. Interest shall be calculated from the date by which the payment should have been made up to the date when the late payment is made at the prevailing rate of interest for commercial borrowing for each of the currencies in which payments are made.

43.2 If an amount certified is increased in a later certificate or as a result of an award by the Adjudicator or an Arbitrator, the Contractor shall be paid interest upon the delayed payment as set out in this clause. Interest shall be calculated from the date upon which the increased amount would have been certified in the absence of dispute.

43.3 Unless otherwise stated, all payments and deductions shall be paid or charged in the proportions of currencies comprising the Contract Price.

43.4 Items of the Works for which no rate or price has been entered in shall not be paid for by the Contracting Agency and shall be deemed covered by other rates and prices in the Contract.

44. Compensation Events

44.1 The following shall be Compensation Events:

(a) The Contracting Agency does not give access to a part of the Site by the Site Possession Date pursuant to GCC Sub-

58

Clause 21.1.

(b) The Contracting Agency modifies the Schedule of Other Contractors in a way that affects the work of the Contractor under the Contract.

(c) The Project Manager orders a delay or does not issue Drawings, Specifications, or instructions required for execution of the Works on time.

(d) The Project Manager instructs the Contractor to uncover work done, or to carry out additional tests upon work, which is then found to have no Defects.

(e) The Project Manager unreasonably does not approve a subcontract to be let.

(f) Ground conditions are substantially more adverse than could reasonably have been assumed before issuance of the Letter of Acceptance from the information issued to bidders (including the Site Investigation Reports), from information available publicly and from a visual inspection of the Site.

(g) The Project Manager gives an instruction for dealing with an unforeseen condition, caused by the Contracting Agency, or additional work required for safety or other reasons.

(h) Other contractors, public authorities, utilities, or the Contracting Agency do not work within the dates and other constraints stated in the Contract, and they cause delay or extra cost to the Contractor.

(i) The advance payment is delayed.

(j) The effects on the Contractor of any of the Contracting Agency’s Risks.

(k) The Project Manager unreasonably delays issuing a Certificate of Completion.

44.2 If a Compensation Event would cause additional cost or would prevent the work being completed before the Intended Completion Date, the Contract Price shall be increased and/or the Intended Completion Date shall be extended. The Project Manager shall decide whether and by how much the Contract Price shall be increased and whether and by how much the Intended Completion Date shall be extended.

44.3 As soon as information demonstrating the effect of each

59

Compensation Event upon the Contractor’s forecast cost has been provided by the Contractor, it shall be assessed by the Project Manager, and the Contract Price shall be adjusted accordingly. If the Contractor’s forecast is deemed unreasonable, the Project Manager shall adjust the Contract Price based on the Project Manager’s own forecast. The Project Manager shall assume that the Contractor shall react competently and promptly to the event.

44.4 The Contractor shall not be entitled to compensation to the extent that the Contracting Agency’s interests are adversely affected by the Contractor’s not having given early warning or not having cooperated with the Project Manager.

45. Tax 45.1 The Project Manager shall adjust the Contract Price if taxes, duties, and other levies are changed between the date 28 days before the submission of bids for the Contract and the date of the last Completion certificate. The adjustment shall be the change in the amount of tax payable by the Contractor, provided such changes are not already reflected in the Contract Price or are a result of GCC Clause 47.

46. Currencies 46.1 Where payments are made in currencies other than the currency of the Contracting Agency’s country specified in the SCC, the exchange rates used for calculating the amounts to be paid shall be the exchange rates stated in the Contractor’s Bid.

47. Price Adjustment

47.1 Prices shall be adjusted for fluctuations in the cost of inputs only if provided for in the SCC. If so provided, the amounts certified in each payment certificate, before deducting for Advance Payment, shall be adjusted by applying the respective price adjustment factor to the payment amounts due in each currency. A separate formula of the type indicated below applies to each Contract currency:

Pc = Ac + Bc (Imc/Ioc)

where:

Pc is the adjustment factor for the portion of the Contract Price payable in a specific currency “c.”

Ac and Bc are coefficients specified in the SCC, representing the nonadjustable and adjustable portions, respectively, of the Contract Price payable in that specific currency “c;” and

Imc is the index prevailing at the end of the month being invoiced and Ioc is the index prevailing 28 days before Bid opening for inputs payable; both in the specific currency

60

“c.”

47.2 If the value of the index is changed after it has been used in a calculation, the calculation shall be corrected and an adjustment made in the next payment certificate. The index value shall be deemed to take account of all changes in cost due to fluctuations in costs.

48. Retention 48.1 The Contracting Agency shall retain from each payment due to the Contractor the proportion stated in the SCC until Completion of the whole of the Works.

48.2 On completion of the whole of the Works and the Project Manager certification of completion of the works according to GCC Sub-Clause 55.1, half the total amount retained shall be repaid to the Contractor and half when the Defects Liability Period has passed and the Project Manager has certified that all Defects notified by the Project Manager to the Contractor before the end of this period have been corrected.

48.3 On completion of the whole Works and the Project Manager certification of completion of the works according to GCC Sub-Clause 55.1, the Contractor may substitute retention money with an “on demand” Bank guarantee.

49. Liquidated Damages

49.1 The Contractor shall pay liquidated damages to the Contracting Agency at the rate per day stated in the SCC for each day that the Completion Date is later than the Intended Completion Date. The total amount of liquidated damages shall not exceed the amount defined in the SCC. The Contracting Agency may deduct liquidated damages from payments due to the Contractor. Payment of liquidated damages shall not affect the Contractor’s liabilities.

49.2 If the Intended Completion Date is extended after liquidated damages have been paid, the Project Manager shall correct any overpayment of liquidated damages by the Contractor by adjusting the next payment certificate. The Contractor shall be paid interest on the overpayment, calculated from the date of payment to the date of repayment, at the rates specified in GCC Sub-Clause 43.1.

50. Bonus 50.1 The Contractor shall be paid a Bonus calculated at the rate per calendar day stated in the SCC for each day (less any days for which the Contractor is paid for acceleration) that the Completion is earlier than the Intended Completion Date. The Project Manager shall certify that the Works are complete,

61

although they may not be due to be complete.

51. Advance Payment

62.1The Contracting Agency shall make advance payment to the Contractor of the amounts stated in the SCC by the date stated in the SCC, against provision by the Contractor of an Unconditional Bank Guarantee in a form and by a bank acceptable to the

62.2Contracting Agency in amounts and currencies equal to the advance payment. The Guarantee shall remain effective until the advance payment has been repaid, but the amount of the Guarantee shall be progressively reduced by the amounts repaid by the Contractor. Interest shall not be charged on the advance payment.

51.2 The Contractor is to use the advance payment only to pay for Equipment, Plant, Materials, and mobilization expenses required specifically for execution of the Contract. The Contractor shall demonstrate that advance payment has been used in this way by supplying copies of invoices or other documents to the Project Manager.

51.3 The advance payment shall be repaid by deducting proportionate amounts from payments otherwise due to the Contractor, following the schedule of completed percentages of the Works on a payment basis. No account shall be taken of the advance payment or its repayment in assessing valuations of work done, Variations, price adjustments, Compensation Events, Bonuses, or Liquidated Damages.

52. Securities 52.1 The Performance Security shall be provided to the Contracting Agency no later than the date specified in the Letter of Acceptance and shall be issued in an amount specified in the SCC, by a bank or surety acceptable to the Contracting Agency, and denominated in the types and proportions of the currencies in which the Contract Price is payable. The Performance Security shall be valid until a date 28 days later than the date of issue of the Certificate of Completion in the case of a Bank Guarantee, and until one year later than the date of issue of the Completion Certificate in the case of a Performance Bond.

53. Daywork 53.1 If applicable, the Daywork rates in the Contractor’s Bid shall be used for small additional amounts of work only when the Project Manager has given written instructions in advance for additional work to be paid for in that way.

53.2 All work to be paid for as Daywork shall be recorded by the Contractor on forms approved by the Project Manager. Each

62

completed form shall be verified and signed by the Project Manager within two days of the work being done.

53.3 The Contractor shall be paid for Dayworks subject to obtaining signed Dayworks forms.

54. Cost of Repairs

54.1 Loss or damage to the Works or Materials to be incorporated in the Works between the Start Date and the end of the Defects Correction periods shall be remedied by the Contractor at the Contractor’s cost if the loss or damage arises from the Contractor’s acts or omissions.

57. Final Account 57.1 The Contractor shall supply the Project Manager with a detailed account of the total amount that the Contractor considers payable under the Contract before the end of the Defects Liability Period. The Project Manager shall issue a Defects Liability Certificate and certify any final payment that is due to the Contractor within 56 days of receiving the Contractor’s account if it is correct and complete. If it is not, the Project Manager shall issue within 56 days a schedule that states the scope of the corrections or additions that are necessary. If the Final Account is still unsatisfactory after it has been resubmitted, the Project Manager shall decide on the amount payable to the Contractor and issue a payment certificate.

58. Operating and Maintenance Manuals

58.1 If “as built” Drawings and/or operating and maintenance manuals are required, the Contractor shall supply them by the dates stated in the SCC.

59.3 When either party to the Contract gives notice of a breach of Contract to the Project Manager for a cause other than those listed under GCC Sub-Clause 59.2 above, the Project Manager shall decide whether the breach is fundamental or not.

59.4 Notwithstanding the above, the Contracting Agency may terminate the Contract for convenience at any time.

59.5 If the Contract is terminated, the Contractor shall stop work immediately, make the Site safe and secure, and leave the Site as

The rates for earthworks shall be deemed to cover earthworks above and below water and in any material except those otherwise described, e.g. unsound material, and for which separate items are provided.

The cost of dealing with unsound material in any part of the Works shall be borne by the Contractor if in the opinion of the Engineer the unsoundness is due to failure of the Contractor to comply with the Specifications including keeping the excavation free of water.

Excavation in open cut shall be measured where the sides of the finished excavation are shown on the Drawings as free-standing.

Excavation in foundation shall be measured as the volume of the product of the horizontal area of the base of the Permanent Works to be constructed and the mean depth from the original undisturbed surface, or as the volume below the said surface displaced by the Permanent Works or to the limits of excavation shown on the Drawings, whichever is the greater and which is defined as the net excavation.

Excavation for pipelines shall be measured as the volume of the product of the horizontal area of the pipe bedding to be constructed and the mean depth from the original undisturbed ground surface. The rate shall include backfill and disposal of any surplus material.

Backfill shall be measured as the difference, if any, between the net excavation and the volume below the original undisturbed surface displaced by the Permanent Works.

Fill generally shall be measured as the net volume of fill in the Permanent Works above the original undisturbed surface, and vertically above any part of the Permanent Works, or as ordered by the Engineer.

Fill from approved borrow area shall be measured as the difference between the volume of fill generally required and the volume available from associated excavation.

118

Concrete Work

Unless otherwise described in the Bill of Quantities, concrete work shall be measured in terms of four categories of work, namely: concrete, reinforcement, finishes and protection as described below and set out in the Bill of Quantities.

1. Concrete

Concrete including blinding shall be measured as the net volume of concrete to the dimensions specified or shown on the Drawings in the Permanent Works, but no deductions shall be made in respect of the volume occupied by reinforcement or in respect of small openings, recesses, chases and embedded fixtures having a cross-sectional area less than 0.1 Yd2.

Concrete in each class shall be measured separately in each of the following circumstances irrespective otherwise of location in the Permanent Works:

(a) Mass concrete in situ

(b) Reinforced concrete in situ

Where in the Bill of Quantities separate items are provided for concrete in particular locations or for particular types of work, it shall not be deemed to prejudice the generality of the above rules.

2. Shuttering

Shuttering shall be measured for all final surfaces of in-situ concrete which require temporary support during casting except where otherwise specified or indicated on the Drawings. Shuttering shall be measured in the following categories, irrespective of location in the Works Back shuttering, for all surfaces which will remain hidden in the Permanent Works and which are vertical or of a slope steeper than 1 in 1 Face shuttering, for plane surfaces which will remain exposed in the Permanent Works and which are vertical or of slope steeper than 1 in 1 Soffit shuttering, for plane soffit surfaces which will remain exposed and which are horizontal or of a slope not steeper than 1 in 1.

Shuttering shall not be measured for precast concrete or for concrete for bridge works.

Shuttering shall not be measured for chamfered arises not greater than 2” x 2” or for construction joints, stop ends, stepping, bond chases and the like which may

119

be necessary in addition to the shuttering required to support the surface of the finished concrete.

No deductions shall be made from measurement of shuttering for forming holes for pipes and the like having an area at the face of shuttering less than 1 Yd 2.
