or other design document. The list of required materials for construction is sometimes referred to as the material take off list (MTOL). Material take off is not limited to the amount of required material, but also the weight of the items taken off. This is important when dealing with larger structures, allowing the company that does the take off to determine total weight of the item and how best to move the item (if necessary) when construction is completed.


Definition used by the ISA (International Society of Automation)

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 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 ...
(BOM). Procurement and requisition are activities that occur after the bill of materials is complete, distinct from Inspection.
