A bill of materials or product structure (sometimes bill of material, BOM or associated list) is a list of the raw materials, sub-assemblies, intermediate assemblies, sub-components, parts, and the quantities of each needed to manufacture an end product. A BOM may be used for communication between manufacturing partners or confined to a single ...
For instance, a bill of quantities is a list of all the materials (and other work such as amount of excavation) of a project which have sufficient detail to obtain a realistic cost, or rate per described item of work/material.
This is sometimes called independent demand, or Level "0" on BOM (bill of materials). How much is required at a time. When the quantities are required to meet demand. Shelf life of stored materials. Inventory status records. Records of net materials available for use already in stock (on hand) and materials on order from suppliers. Bills of ...
A material take off (MTO) is the process of analyzing the drawings and determining all the materials required to accomplish the design. Thereafter, the material take off is used to create a bill of materials (BOM). Procurement and requisition are activities that occur after the bill of materials is complete, distinct from Inspection.
After operational bills were proposed, a second half-way house version with bills of quantities was suggested initially called "activity bills", but then as "Bills of quantities (operations)". In this, the operations are described in terms of the rules of the standard method of measurement rather than labour and materials.
Tendering in the UK construction industry is traditionally based upon Bills of quantities in which the estimation of costs is based on the combined cost of materials, building plant and labour in the completed works. Edward Skoyles proposed a new form of tendering, operational bills in which such tendering was based around building tasks.
