SECTION 1: BILL OF QUANTITIES
Tenderers must price each item in the bill of quantities separately and follow the instructions regarding the transfer of various totals in the summary.
The bill of quantities must be read with all the other contract documents and the Contractor shall be deemed to have thoroughly acquainted himself with the detailed descriptions of the works to be done and the way in which they are to be carried out. All the works must be executed to the satisfaction of the Supervisor.
1.1 Quantity of items
The quantities set forth against the items in the bill of quantities are an estimate of the quantity of each kind of the work likely to be carried out under the contract and are given to provide a common basis for bids. There is no guarantee to the Contractor that he will be required to carry out the quantities of work indicated under any one particular item in the bill of quantities or that the quantities will not differ in magnitude from those stated.
When pricing items, reference should be made to the conditions of contract, the specifications and relevant drawings for directions and descriptions of work and materials involved.
The quantities given in the bill of quantities are provisional and reflect the estimates made at the time of approval to provide a basis for this dossier and tenders. Tenderers must consider every aspect of the dossier carefully.
Any comments concerning the quantities must be made in the form of an attachment, following the system of itemisation, quoting the codes and brief descriptions, as in the present documents, including the rates and prices.
Save where the technical specifications or the bill of quantities specifically and expressly state otherwise, only permanent works are to be measured. Works will be measured net to the dimensions shown on the drawings or ordered in writing by the Supervisor, save where described or prescribed elsewhere in the contract.
In adjusting extras or variations on the contract, works will be measured on the same basis as that on which the quantities were prepared. All works not specifically mentioned in the bill of quantities will be taken as included in the prices of various items.
Where, in the opinion of the Supervisor, extra works cannot be properly measured or valued, the Contractor may, if so directed by the Supervisor, carry out the work at the daywork rates shown in the schedule of daywork. All completed daywork sheets must be signed by the Supervisor on or before the end of the week in which the works are executed.
No allowance will be made for loss of materials or volume thereof during transport or compaction.
1.2 Units of measurement
The units of measurement used in the annexed technical documentation are those of the International System of Units (SI). No other units may be used for measurements, pricing, detail drawings etc. (Any units not mentioned in the technical documentation must also be expressed in terms of the SI.)
Abbreviations used in the bill of quantities are to be interpreted as follows:
TERMS RELATING TO PAYMENTS
The method for measuring completed works for payment must be in accordance with Clause 47.1 (v) of the General Conditions (net measurement), save where Section II, "Description of the items of the bill of quantities" provides otherwise.
The provisional sums in the bill of quantities must be used in whole or in part at the discretion of the Supervisor.
Each item in the bill of quantities for which payment is to be made in a lump sum, and for which no payment schedule is provided, must be paid after the work covered by the lump sum has been completed to the satisfaction of the Supervisor.
The prices and rates inserted in the bill of quantities are to be the full inclusive values of the works described under the items, including all costs and expenses which may be required in and for the construction of the works described together with any temporary works and installations which may be necessary and all general risks, liabilities and obligations set forth or implied in the documents on which the tender is based. It will be assumed that establishment charges, profit and allowances for all obligations are spread evenly over all the unit rates.
The rates and prices tendered in the priced bill of quantities will be quoted at the rates current prior to the date of submission.
Rates and prices must be entered against each item in the bill of quantities. The rates will cover all applicable taxes, duty and other liabilities.
Bids must be submitted in accordance with the tax and customs arrangements for EDF funded programmes (Article 31 of Annex IV to the Cotonou Agreement), and those under Section 138(1) and (2) (g) of the Customs Act and sections 23 (i) and (3) (e) of the VAT Act, and Legal Notices 138 and 145 of 1992 and legal notice No. 67 of 2003.

(b) profits and/or income arising from the performance of contracts shall be taxable according to
the internal fiscal arrangements of the ACP State concerned, provided that the natural or legal persons who realise such profit and/or income have a permanent place of business in that State, or that the performance of the contract takes longer than six months;

temporarily admitted into the beneficiary ACP State or States in accordance with its national legislation free of fiscal, import and customs duties and of other charges having equivalent effect where these duties and charges do not constitute remuneration for services rendered;
(e) imports under supply contracts shall be admitted into the beneficiary ACP State without
customs duties, import duties, taxes or fiscal charges having equivalent effect. The contract for supplies originating in the ACP State concerned shall be concluded on the basis of the ex-works price of the supplies to which may be added such internal fiscal charges as may be applicable to those supplies in the ACP State;

SECTION 2: PRICE ADJUSTMENT COEFFICIENTS AND BASE INDICES
SECTION 2: PRICE ADJUSTMENT COEFFICIENTS AND BASE INDICES
SCHEDULE A: CONTRACT INDICES
Tenderers shall provide the information required below.
The tenderer shall enter in a table with identical structure to the one that follows, his proposed weightings
for the coefficients that will be applied uniformly to applicable payments following the provisions of Article
48 of the Special Conditions
of Contract (Price Revision).
The coefficients a, b, c, d etc. included in the price revision formula have the following meaning:
« a » is the percentage of total cost of other components non revised on the total amount of contract
« b » is the percentage of total cost of labour on the total amount of contract
« c » is the percentage of total cost of equipment maintenance on the total amount of contract
« d » is the percentage of total cost of fuel on the total amount of contract.
a + b + c + d = 1
These coefficients must be calculated by the tenderer on the basis of a detailed price breakdown and
submitted in the tender together with methodology used and clear arithmetical calculations. There is no
single way to obtain them, as it will depend on factors like if a certain contractor relies more on mechanical
equipment or of labour force to carry out some particular work.

considers the information to be inadequate or that the weighting values derived are in any way
