PART 3

ELECTRICAL AND ELECTRONIC SERVICES SCHEDULE OF QUANTITIES

JOSHCO LOMBARDY EAST HOUSING DEVELOPMENT BUILDING ELECTRICAL PROJECT SPECIFICATION REV 0 26

PREAMBLE TO THE SCHEDULE OF QUANTITIES

(a) For the purpose of this schedule of quantities the following words shall have the meanings hereby assigned to them:

Payment Item : This number refers to the relevant clause in the specification that

describes the item

Item No : This number is for reference only

Description : The description clarifies what the item is for

Unit : The unit of measurement for each item of work as defined in the standard specifications or the special provisions of contract

Quantity : The number of units of work for each item

Rate : Payment per unit of work or material at which tenders offer to do the work or supply material

Amount : The product of quantity and rate

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

(b) This schedule of quantities forms part of the contract and shall be read in conjunction with all the other documents comprising the contract documents.

(c) The quantities set out in the schedule of quantities are approximate only and the quantities of work finally accepted and certified for payment, and not the quantities given in the schedule of quantities, shall be used for determining payments 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. Work shall be valued at the rate or lump sum prices tendered, subject only to the provisions of the general conditions of contract and the provisions of paragraphs (k) and (l) of this preamble.

(d) Rates and lump sum prices shall include full compensation for overheads, profits, incidentals, etc, and for the completed items of work as specified. Full compensation for completing, and maintaining during the maintenance period, all the work shown on the drawings and specified in the project specifications and for all the risks, obligations and responsibilities specified in the tender rules, general conditions of contract, special conditions of contract and project 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.

(e) The Tenderer must fill in a rate or lump sum to each item where provision is made for it, even where no quantities are given. Items against which no rate or lump sum has been entered in the tender will not be paid for when executed, as payment for such work will be regarded as covered by other rates or lump sums in the schedule of quantities.

The Tenderer must fill in a rate opposite all items where the words "rate only" appears in the "Price" column. The intention is that although no work is foreseen under such an item, and no quantities are accordingly given in the "Quantity" column, the tendered rate shall apply in the

JOSHCO LOMBARDY EAST HOUSING DEVELOPMENT BUILDING ELECTRICAL PROJECT SPECIFICATION REV 0 27

event of work under this item being actually required. The attention of the Tenderers is directed to the provisions of paragraph (l) of this preamble.

If the Tenderer should group a number of items together and tender one lump sum for such group of items the single tendered lump sum shall apply to that group of items and not to each individual item, or should he indicate against any item that full compensation for such item has been included in another item, the rate for the item included in another item shall be deemed to be nil.

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

(f) 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. Except where otherwise specified, the net measurements 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.

(g) The quantities of work or 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.

(h) The quantities of material or work stated in the schedule of quantities shall not be regarded as authorisation 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. Material shall be ordered according to the construction drawing routing, and measurements taken on site.

(i) The short descriptions given of payment items 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, 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. Where supply, deliver and install items are specified in the BOQ the rates shall include the complete installation e.g. wire ways, wiring, cables, terminations etc. of the specific items mentioned. The item shall be in a completely installed and working state.

(j) Reference shall be made to the general conditions of contract regarding provisional sums.

(k) Subject to the conditions stated in paragraph (l) below, the rates and lump sums filled in by the Tenderer in the schedule of quantities shall be final and binding and may not be adjusted should there be mistakes in the extensions thereof. Should there be any discrepancies between the correctly extended and totalled schedule of quantities and the tender sum, the Employer shall have the right to make such adjustments to the tender sum as he may deem necessary in order to reconcile the total of the schedule of quantities with the tender sum. In their own interest Tenderers should make doubly sure of the correctness of their tendered rates, the extensions and the tender sum.

(l) A tender may be rejected if the unit rates or prices for some of the items in the schedule of quantities are, in the opinion of the Employer, unreasonable or out of proportion, and the Tenderer fails, within a period of seven (7) days after having been notified in writing by the Employer to adjust the unit rates or prices of such items, to make such adjustments.

(m) The units of measurement indicated in the schedule of quantities are metric units. Abbreviations used in the schedule of quantities are as follows:

mm = millimetre

m = metre

km = kilometre

JOSHCO LOMBARDY EAST HOUSING DEVELOPMENT BUILDING ELECTRICAL PROJECT SPECIFICATION REV 0 28

m2 = square metre

m3 = cubic metre

No = number

P.C. sum = Prime cost sum

Prov. sum = Provisional sum

(n) The Tenderer's rates shall not include VAT.

VAT shall be added to the total value of the contract in the item specifically allowed for VAT in the calculation of the tender sum.

(o) Note:

The main offer must be as per specification; i.e. without qualification. If Tenderers offer alternatives, these can be included in an “alternative bid” under a separate covering letter.
