A tender document showing all the work that contractor's price for which they are bidding for.
The first step in preparing a bill of quantities is called 'taking off' - the recording of dimensions from path survey notes and drawings onto dimension paper.
A bill of quantities shows a list of numbered work items that describe the work to be carried out in a path construction project. Each numbered work item shows a written description (referring to specifications and relevant contract drawing) and the quantity of work to be completed.
You issue the bill of quantities to Contractor's (also known as tenderers), who return it to you with rates and costs opposite each numbered work item. Their priced bill of quantities constitutes their offer to complete the work.
For large scale path construction projects, the general practice is to separate a bill of quantities into individual bills showing preliminaries, construction work items and provisional sums all on one bill of quantities.
The image below shows a typical page of a unpriced bill of quantities. A priced bill is exactily the same but with rates, costs and total shown.
