With JCT contracts, the clerk of works has no legal power to approve anything or give instructions to a contractor, as stated by JCT Intermediate Building Contract 2009 and JCT Intermediate Building Contract with Contractor’s Design 2009, under clause 3.2. It is essential that an architect makes it clear to a contractor that work should not be approved on the basis of the clerk of works’ word as the architect may ultimately be held liable for any errors that occur from such conduct.
