C2.1Pricing instructions: Option B

1. The conditions of contract

1.1. How the contract prices work and assesses it for progress payments

Clause 11 in NEC3 Engineering and Construction Contract, June 2005 (ECC) Option B states:

Identified and defined terms

11

11.2

(21) The Bill of Quantities is the bill of quantities as changed in accordance with this contract to accommodate implemented compensation events and for accepted quotations for acceleration.

(22) Defined Cost is the cost of the components in the Shorter Schedule of Cost

Components whether work is subcontracted or not excluding the cost of preparing quotations for compensation events

(28) The Price for Work Done to Date is the total of

The quantity of the work which the Contractor has completed for each item in the Bill of Quantities multiplied by the rate and

A proportion of each lump sum which is the proportion of the work covered by the item which the Contractor has completed.

Completed work is work without Defects which would either delay or be covered by immediately following work.

(31) The Prices are the lump sums and the amounts obtained by multiplying the rates by the quantities for the items in the Bill of Quantities.

This confirms that Option B is a re-measurement contract and the bill comprises only items measured

using quantities and rates or stated as lump sums. Value related items are not used. Time related items

are items measured using rates where the rate is a unit of time

1.2. Measurement and Payment

Clause 55.1 in Option B states, “Information in the Bill of Quantities is not Works Information or Site

Information”. This confirms that instructions to do work or how it is to be done are not included in the Bill,

but in the Works Information. Tis is further confirmed by Clause 20.1 which states, “The contractor

provides the Works in accordance with the Works Information”. Hence the Contractor does not provide

the Works in accordance with the Bill of Quantities. The Bill of Quantities is only a pricing document.

1.3. Guidance before Pricing and Measuring

a) Employers preparing tenders or contract documents, and tendering contractors are advised to consult

the sections dealing with the bill of quantities in the NEC3 Engineering and Construction Contract

(June 2014) Guidance Notes before preparing the bill of quantities or before entering rates and lump

sums into the bill.



b) Historically, bill of quantities based contracts in South Africa have been influenced by the different

approaches of the civil engineering and building sectors of the industry through their respective

discipline based standard forms of contract and methods of measurement. This is particularly

apparent in the approach to the Preliminary and General Bill. On the other hand, because ECC3

caters for a number of disciplines in the same contract, including electrical works, a different

approach not currently found in local methods of measurement to the Preliminary and General Bill

items may have been used.

c) The NEC approach to the P&G bill assumes use will be made of method related charges for

Equipment applied to Providing the Works based on durations shown in the Accepted Programme,

fixed charges for the use of equipment that is required throughout the construction phase, time

related charges for people working in a supervisory capacity for the period required, and a lump sum

charges for other facilities or services not directly related to performing work items typically included

in other parts of the bill.

1.4. Symbols

The units of measurement described in the Bill of Quantities are metric units abbreviated as follows:

Abbreviation Description

m Meter

mm Millimetres

m2 Meters Squared

m3 Meters Cubed

Sum Lump Sum

ton Metric Ton (1000kg)

1.5. General Assumptions

d) Unless otherwise stated, items are measured net in accordance with the drawings, and no allowance

has been made in the quantities for waste.

e) The prices and rates stated for each item in the Bill of Quantities shall be treated as being fully

inclusive of all work, risks, liabilities, obligations, overheads, profit and everything necessary as

incureed or required by the Contractor in carrying out or providing that item.

f) Clause 63.13 in Option B provides that these rates and Prices may be used as a basis for

assessment of compensation events instead of defined cost.



g) Where the contract requires detailed drawings, designs or other information to be provided, and no

rates or prices are included in the Bill specifically for such matters, then the Contractor is deemed to

have allowed for all costs associated with such requirements within the tendered rates and Prices in

the Bill of Quantities.

h) An item against which no Price is entered will be treated as covered by other Prices or Rates in the

Bill of Quantities. If a number of items are grouped together for pricing purposes, this will be treated

as a single lump sum.

i) The quantities contained in the Bill of Quantities may not be final and do not necessarily represent the

actual amount of work to be done. The quantities of work assessed and certified for payment by the

Project Manager at each assessment date will be used for determining payments due and not the

quantities given in the Bill of Quantities.

j) The short descriptions of the items of payment given in the Bill of Quantities are only for the purposes

of identifying the items. More detail regarding the extent of the work entailed under each item is

provided in the Works Information.

1.6. Amplification of or assumptions about measurement items

For the avoidance of doubt, the following is provided to assist in the interpretation of descriptions given in

the method of measurement. In the event of any ambiguity or inconsistency between the statements in

the method of measurement and this section, the interpretation given in this section shall be used.
