What is a Clerk of Works?
The Clerk of Works, often abbreviated to CoW, is employed by an architect, project manager or a client on a construction site. The role is primarily to represent the interests of the client in regard to checking that the quality of both materials and workmanship are in accordance with the design information. This includes such items as specification, Architect’s 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.

How does it work?
Your Clerk of Works will provide an independent assessment of the works undertaken. He will check the quality of the build, M&E, structural and architectural works. He will produce regular reports and raise any non-compliant works with the contractors site team and log defects to be re-inspected when rectified. Reporting will include progress reports, photographs, monitoring and recording progression of the works against the contract programme and a defective works log and tracker.
A Clerk of Works can attend site on a full or part-time basis depending on your project requirements and budget. A Clerk of Works is your “eyes and ears on site” and will work dilligently with the contractor’s team to help them “get it right first time” and aid them in handing over a defects free project.
