Bill of Quantities Definition

"Bill of Quantities" means the priced and completed Bill of Quantities.
(ICE Conditions of Contract Definition)

Bills of quantities: In traditional contracting, a contract document comprising a list of the materials required for the works and their estimated quantities, produced by the quantity surveyor.

The contractor tenders against this document, stating his price for supplying and installing each of the materials.

The total of the contractor's prices, added to his prices for the various items in the Preliminaries, forms the contract sum.

The contract sum cannot be varied just because the actual quantities differ from those in the bills of quantities, so the contractor must satisfy himself that the quantities shown are at least approximately correct.
