We are the contractor on an ECC contract. Can a general communication be used to resolve an ambiguity under clause 17.1 if the works information requires changing? It is our understanding that only a project manager’s instruction under clause 14.3 may change the works information, however our client is suggesting the response to a general communication under clause 17.1 is sufficient and that a separate project manager’s instruction is not required.
If there is an ambiguity or inconsistency, the project manager is required to issue an instruction resolving it. If the project manager’s instruction changes the works information, that will be a compensation event under clause 60.1(1), unless one of the exceptions in that clause applies.
