Bill of quantities

From Wikipedia, the free encyclopedia

In a formal, traditional construction project in the United Kingdom, a bill of quantities is used as a form of cost planning and mapping to monitor and control the construction cost during the execution or post-contract period of construction.

These documents originated historically as non-contractual measurements, taken off drawings to assist tenderers in quoting lump sum prices.

Bills of quantities are drawn up and specified by a cost professional called a quantity surveyor and prepared in advance to take into account the works required for a project, and then later used as a tender document to acquire rates from contractors who would be interested in winning the job.

There are different styles of bills of quantities, mainly the Elemental BOQ and Trade Bills.
