A specification, in construction terms, describes the works by defining the materials to be used, the level of workmanship, the quality and the tolerances to which the components are assembled, both individually and as a whole, to form the building.

Specifications reflect the peculiarities and individualities of particular projects, and should be prepared both as generic and bespoke documents. The codes of practice applicable to different areas of design and products should be defined.

Legislation affecting the project should be referred to in both specific and general terms.
