Bill of Quantities (BQ) is a document detailing the qualitative and quantitative aspects of every constituent parts of a proposed construction project.
Qualitative: Description of material, labour and
workmanship for the work
Quantitative: Quantity of material, labour and workshop
Hackett & Robinson (2003) and Chan (2002)
It is compiled together with the form of tender, specification, preliminary bill and list of drawings to form a tender document.

1. Price is based on quantities and is subject to final re-measurements on completion.
2. Variations means difference due to design
schematics, concepts or addition in scope (i.e. additional system not in drawings).
3. Variations valid only on Architect ’s instructions. 4. BQ form the basis of Contract Works.
5. Specifications determines the qualitative aspect of works.

1. Contract Price is firm and shall not be subject to revision. 2. Variations only on Architect’s instructions.
3. Drawings form the basis of Contract Works (determining the contract drawings before contract binding is therefore important).
4. Specifications determines the qualitative aspect of works. 5. BQ or price schedule augment drawings.
6. Variations and final account is determined by comparison with Contract Drawings and final As-Built (however changes from Contract Drawings can only claimed Variations based on AI).

PAM Contract forms are popular contract forms for
private buildings in Malaysia.
M&E engineers who are responsible for drafting
sub contract forms and ultimately managing the M&E portion of the sub contract should understand major differences in contract management required between the two forms.

The risk allocation for time, money matters, quality issues and dispute
resolution between the contractor, employer and consultant team has been shifted significantly in the PAM 2006. Comparatively (1998/2006) the risk for Contractors under 2006 has been shifted towards the Employer.
This reallocation of risks proportionately increases the employer’s
exposure and burden in terms of claims and payments while providing more possible grounds for disputes between the contractor and employer.
PAM 2006 Forms are also more procedural requiring the contractor,
employer and consultants to strictly adhere to time provisions with the attendant loss of rights or incurring of liabilities.
PAM 2006 imposes definite and at times, mandatory time periods on the
Architect/consultant team to carry out certain duties, for example, certification and approvals within a specified time. The failure to do so may open the consultant team to professional negligence claims.
