A component is a constituent part of a building (or other built asset) which is manufactured as an independent unit, subsystem or subassembly, that can be joined or blended with other elements to form a more complex item. Generally, components are ‘self-contained’ and sourced from a single supplier, typically the complete unit provided by that supplier rather than its constituent parts.
Where a component is a bespoke item, it may be necessary to prepare a component drawing. Where a component is an off-the-shelf-product or a commonly-used element, a component drawing may already exist that can be re-used.
Component drawings provide detailed information about the individual units. They may be drawn at large scales such as; 1:10, 1:5, 1:2, 1:1, and so on. They may include information such as component dimensions, construction, tolerances, and so on. They may include references to the relevant parts of the specification providing information about materials and the minimum acceptable quality.
Component drawing numbers may be prefixed by the letter C.
