C2.1 Pricing Instructions

For the purposes of this schedule of quantities, the following words shall have the meanings hereby assigned to them:

Unit: The unit of measurement for each item of works as defined in the specifications.

Quantity: The number of units of work for each item.

Rate: The payment per unit of measurement at which the tenderer tenders to do the work.

Amount: The product of the quantity and the rate tendered for an item.

Lump sum: An amount tendered for an item, the extent of which is described in the schedule of quantities, the specifications or elsewhere but the quantity of work of which is not measured in any units.

This schedule of quantities forms an integral part of the contract documents.

The quantities set out in the schedule of quantities are approximate quantities only. The quantities of workfinally accepted and certified for payment, and not the quantities given in the schedule of quantities, shall be used for determining payment to the contractor.

The validity of the contract shall in no way be affected by differences between the quantities in the schedule of quantities and the quantities finally certified for payment. Works shall be valued at the rates or lump sums tendered, subject only to the provisions for the general conditions of contract, paragraphs 11 and 12 of this preamble, and subclause 1209(a) of the standard specifications.

Rates and lump sums shall be comprehensive in accordance with subclause 1209(b) of the standard specifications. Full compensation for completing and maintaining, during the maintenance period, all the work shown on the drawings and specified in the specifications, and for all the risks, obligations and responsibilities specified in the general conditions of contract, special conditions of contract and specifications shall be considered as provided for collectively in the items of payment given in the schedule of quantities, except in so far as the quantities given in the schedule of quantities are only approximate.

The tenderer shall fill in a rate or a lump sum for each item where provision has been made for it, even where no quantities are given.

A tender may be rejected if the tenderer has not filled in a rate or a lump sum against each item and if the tenderer fails to furnish the rates or lump sums for such items within seven (7) days of having been notified in writing by the employer to do so.

The tenderer shall fill in a rate against all items where the words "rate only" appears in the amount column.

The provisions of subclause 1209(f) of the standard specifications shall apply to rate-only items.

Tenderers shall also note the provisions of paragraph 12 of this preamble.

The tenderer may not group a number of items together and tender one lump sum for such group of items.

The tenderer also may not indicate against any item that full compensation for such item has been included in another item.

The tendered lump sums and rate shall be valid irrespective of any change in the quantities during the execution of the contract.

The works as executed will be measured for payment in accordance with the methods described in the contract documents under the various payment items, notwithstanding any custom to the contrary. Attention is directed to the provisions of clause 1220 of the standard specifications regarding the measurement of quantities for payment. Except where otherwise specified as in clause 1220, the nett measurement or mass of the finished work in place shall be taken for payment but excluding any volume or mass of work in excess of that ordered.

The amount of work or the quantities of material stated in the schedule of quantities shall not be considered as restricting or extending the amount of work to be done or quantity of material to be supplied by the contractor.

The stating of quantities of material or amount of work in the schedule of quantities shall not be regarded as authorization for the contractor to order material or to execute work. The contractor shall obtain the engineer's detailed instructions for all work before ordering any materials for or executing work or making arrangements in this regard.

The short descriptions of the payment items given in the schedule of quantities are only for the purposes of identifying the items and providing specific details. Reference shall be made, inter alia, to the drawings, standard specifications, project specifications, general conditions of contract and special conditions of contract for more detailed information regarding the extent of the work entailed under each item.

Reference shall be made to clause 48 of the general conditions of contract regarding provisional sums and prime cost sums.

Subject to the conditions stated in paragraph 12 below, the rates and lump sums filled in by the tenderer inthe schedule of quantities shall be final and binding and may not be adjusted should there be any mistakes in the extensions thereof. Should there be any discrepancies between the correctly extended totalled schedule of quantities and the tender sum, the rates will be regarded as being correct, and the employershall have the right to make such adjustments to the tender sum as he may deem necessary in order toreconcile the total of the schedule of quantities with the tender sum. In such an event the contractor will be consulted but failing agreement between the parties, the decision of the employer shall be final and binding. Such adjustment of the tender sum shall take place only after acceptance of the tender, but prior to the signing of the contract. In their own interest tenderers should make double sure of the correctness of their tendered rates, the extensions and the tender sum.

A tender may be rejected if the unit rates or lump sums for some of the items in the schedule of quantitiesare, in the opinion of the employer, unreasonable or out of proportion, and the tenderer fails, within a period of seven (7) days of having been notified in writing by the employer to adjust the unit rates or lump sums for such items, to make such adjustments.

The units of measurement indicated in the schedule of quantities are metric units. The followingabbreviations are used in the schedule of quantities:

mm = millimetre h = hour

m = metre kg = kilogram

km = kilometre t = ton (1000 kg)

m² = square metre No. = number

m².pass = square metre-pass sum = lump sum

ha = hectare MN = meganewton

m³ = cubic metre MN.m = meganewton-metre

m³.km = cubic metre-kilometre P C sum = Prime Cost sum

l = litre Prov sum = Provisional sum

kl = kilolitre % = per cent

MPa = megapascal kW = kilowatt

All rates and sums of money quoted in the schedule of quantities shall be in rands and whole cents.Fractions of a cent shall be discarded.

The item numbers appearing in the schedule of quantities refer to the corresponding item numbers in thestandard specifications. Item numbers prefixed by the letter B refer to payment items described under part B of the project specifications; those prefixed by C refer to part C, etc for further parts of the project specifications.

Item numbers in schedule B of the schedule of quantities are in addition, preceded by the schedulenumber of each separate part of schedule B of the schedule of quantities, eg payment item 62.02 described in the standard specifications (clause 6210), when used in part 3 of the schedule B of the schedule of quantities, would be numbered 3/62.02, and if this payment item had been amended in part B of the project specifications, the payment item would be indicated as 3/B62.02.

NB: TENDERERS MUST COMPLETE THE SCHEDULE OF QUANTITIES IN BLACK INK
