ABSTRACT
As we have already identified, the principal purpose of measurement is to make available a Bill of Quantities (BQ), which will be used as the basis for the preparation of tenders for construction work. In due course the priced BQ will become one of the contract documents that legally bind the contractor to perform and the client to pay for the construction. In this form, the BQ provides a basis for the valuation of varied works and the preparation of interim or stage payments. It is also likely to be used by the contractor in the administration and
Measurement can therefore be described as the starting point from which construction costs are established. In order for measured items to accommodate the costing process, they must be framed in a way that is meaningful to the sequence and division of operations on site. Costing a document comprising sporadic and unstructured measured items would be impossible.
