A. Preamble

1.

The Bill of Quantities shall be read in conjunction with the Instructions to Bidders, General

and

Special

Conditions

of

Contract,

Technical

Specifications,

and

Drawings.

The

item

number

and

Specification

number

refer

to

the

relevant

sections

of

the

Standard

and/or

Special

Specifications

2.

The quantities given in the Bill of Quantities are estimated and provisional, and are given

to

provide

a

common

basis for bidding. The

basis of payment

will be the

actual

quantities

of

work ordered and carried out, as measured by the Contractor and verified by the Engineer and

valued

at

the

rates

and

prices

bid

in

the

priced

Bill

of

Quantities,

where

applicable,

and

otherwise at such rates and prices as the Engineer may fix within the terms of the Contract.

3.

The

rates

and

prices

bid

in

the

priced

Bill

of

Quantities

shall,

except

insofar

as

it

is

otherwise

provided

under

the

Contract,

include

all

Constructional

Plant,

labour,

supervision,

materials, erection, maintenance, insurance, profit, taxes, and duties, together with all general

risks, liabilities, and obligations set out or implied in the Contract.

4.

A rate or price shall be entered against each item in the priced Bill of Quantities, whether

quantities are stated or not. The cost of Items against which the Contractor has failed to enter

a rate or price shall be deemed to be covered by other rates and prices entered in the Bill of

Quantities.

5.

The whole cost of complying with the provisions of the Contract shall be included in the

Items provided in the priced Bill of Quantities, and where no Items are provided, the cost shall

be deemed to be distributed among the rates and prices entered for the related Items of Work.

6.

Without affecting the generality of the foregoing provisions, the rates and prices entered

by the Contractor in the Bill of Quantities shall include the cost and expense of the following: -

i.

The provision, storage, transport, use and maintenance of all materials, equipment,

machinery and tools.

ii.

The

provision,

maintenance

and

welfare

of

all

staff

and

their

accommodation, transport etc, and the supply of all immigration permits and other

requirements.

iii.

Setting

out,

measuring, inspection,

supervision

and

any

topographical

survey

and

drawing necessary for the execution or measurement of the work.

iv.

The provision, transport, use and maintenance of all consumable stores, fuel, water,

drainage, electricity and telephones.

v.

Sampling, testing and trials, including checking information given by the Engineer.

vi.

Injury

caused

the

works

under

construction,

equipment,

materials

and

consumable stores by weather conditions.

vii.

The

provision,

General directions and descriptions of work and materials are not necessarily repeated nor

summarized

in

the

documentation

shall

be

made

before

entering

prices

against

each

item

in

the

priced

Bill

of

8.

Provisional Sums included and so designated in the Bill of Quantities shall be expended in

whole or in part at the direction and discretion of the Engineer in accordance with Sub-Clause

13.5 and Clause 13.6 of the General Conditions.

9.

The

method

of

measurement

of

completed

work

for

payment

shall

be

as

specified

in

relevant sections of Part 2

–

Works Requirements (Specifications) of the Bid document and in

accordance with the following:

9.1

All

work

completed

under

the

contract

will

be

measured

by

the

Engineer,

using

the

International System of Units.

9.2

The

method

of

measurement

and

computations

to

be

used

in

the

determination

of

quantities

of

material

furnished

and

work

performed

under

the

contract

will

be

those

methods generally recognized as conforming to good engineering practice. The quantities

will be computed net with no allowance for bulking, shrinkage or waste.

9.3

Unless otherwise specified, longitudinal measurements for area computations will be made

horizontally, and no deductions will be made for individual fixtures (or leave

–

outs) having

an area of one square metre or less. Unless otherwise specified, transverse measurements

for

area

computations

will

be

the

net

dimensions

shown

on

the

drawings

or

ordered

in

writing by the Engineer.

9.4

Unless otherwise specified, all contract items which are measured by the linear metre such

as pipe culverts, under drains and similar items shall be measured parallel to the base or

foundation upon which such items are placed.

9.5

In

computing

volumes

of

excavation

the

average

end

area

method

or

other

acceptable

methods will be used.

9.6

Rental

of

equipment

will

be

measured

by

time

in

hours

of

actual

working

time

and

necessary traveling time of the equipment within the limits of the work.

9.7

When

standard

manufactured

items

are

specified

such

as

fence,

wire,

plates,

rolled

shapes, pipe etc, and these items are identified by gauge, unit weight, section dimensions,

etc,

such

identification

will

be

considered

to

be

nominal

weights

or

dimensions.

Unless

more stringently controlled by tolerances in cited specifications, manufacturing tolerances

established by the industries involved will be accepted.

9.8

When the estimated quantities for a specific portion of the work are designated as the pay

quantities

in

the

contract,

they

shall

be

the

final

quantities

for

which

payment

for

such

specific

portion

of the

work

will be made, unless

the

dimensions of said portions of the

work shown on the plans are revised by the Engineer. If revised dimensions result in an

increase or decrease in the quantities of such work, the final quantities for payment will

be revised in the amount by the authorized changes in the dimensions.

10.

Any arithmetic errors in computation or summation will be corrected by the Employer as

follows:

(a)

where there is a discrepancy between amounts in figures and in words, the amount

in words will govern; and

(b)

where

there

is

a

discrepancy

between

the

unit

rate

and

the

total

amount

derived

from the multiplication of the unit price and the quantity, the unit rate as quoted will

govern,

unless

in

the

opinion

of

the

Employer,

there

is

an

obviously

gross
