Clerk of works

The Clerk of Works (or Clerk of the Works), often abbreviated CoW, is employed by an architect or a client on a construction site. The role is primarily to represent the interests of the client in regard to ensuring that the quality of both materials and workmanship are in accordance with the design information such as specification and engineering drawings, in addition to recognized quality standards. The role is defined in standard forms of contract such as those published by the Joint Contracts Tribunal. "Clerks of works" are also the most highly qualified non-commissioned tradesmen in the Royal Engineers. The qualification can be held in three specialisms: electrical, mechanical and construction.
