The Clerk of Works often abbreviated CoW, is employed by the architect or the client on a construction site with the primary responsibility of representing the interests of the client on the project.

The qualification for clerk of works can be held in three specializations: electrical, mechanical and construction. Historically the clerk of works was employed by the architect on behalf of a client or by local authorities to oversee public works. But in modern era the CoW can also be employed by the client (state body/local authority/private client) to monitor design and build projects where the traditional role of the architect is within the design and build project team.  The role The role of this position is based on the impartiality of the clerk of works in ensuring that value for money for the client - rather than the contractor - is achieved through rigorous and detailed inspection of materials and workmanship throughout the building process.

His role is not to judge, but simply to report all occurrences that are relevant to the role.  In many cases, the traditional title has been discarded to comply with modern trends, such as site inspector, architectural inspector and quality inspector, but the requirement for the role remains unchanged since the origins of the title. Clerks of works are either on site all the time or make regular visits. They need to be vigilant in their inspections of a large range of technical aspects of the work.
