The Preambles Bill or Section describes general information and rules which are common to and applicable to the Measured Work Bills
The Preambles Bill or Section generally describes:
Definitions and terminology
Special method of measurement deviating from the Standard Method of Measurement
Rates to include items which describe work or costs to be included in the unit rates
Additional Preambles clauses to give further information as required by the Standard Method of Measurement or as required for the Works are usually given in the Measured Work Bills preceding the relevant measured items
Special method of measurement
In principle, the rules of the Standard Method of Measurement should be strictly followed. However, in case special deviations or clarifications are required, Preambles clauses should be included to state the special method of measurement
When writing the special method of measurement, it is preferred that the clauses of the Standard Method of Measurement from which deviations are to be made should be specifically stated in this manner: "Notwithstanding clause xxx of Section YYY of the Standard Method of Measurement, ZZZ has been measured ….. "
Rates to include items
The Standard Method of Measurement requires that certain clauses be given in the Preambles to describe the scope of work or costs to be included in the unit rates
Apart from these mandatory Preambles clauses, there may be special Preambles clauses which are necessary to amplify the descriptions in the Measured Work Bills
All these Preambles clauses defining the scope of unit rates are called "Rates to include items" or the scope is called "Item coverage"
The Preambles clauses are usually written in the style of: "The rates for <work> shall include for <item coverage>"
The following are alternatives to "shall include for":
shall be deemed to include for
shall be held to include for
are deemed to include for
are held to include for
The Standard Office Preambles should be used as the base for drafting the Preambles for a particular project
Preambles for other projects may be referred to for any special clauses. However, it would be dangerous to use another Project Preambles as the base for drafting for a new project since the deletions from or additions to the Standard Office Preambles specific for the old project may not be applicable to the new project and fine changes may easily miss the reader’s attention
Amendments to Office Standard Preambles for a particular project must be subject to strict control. Any special Preambles clauses considered necessary during the course of BQ production should be discussed and clarified with the Supervisor-in-charge, above the level of team leader
Similar to the Specification, the Preambles should be lined through
