Failure to Manage design - CE clause

NEC3 Option A - Build Only project

The Client has full responsibility for design management, with the exception (of course) of as-built drawings.

However, the drawings being issued were essentially incomplete and needed a number of RFI's to be raised to provide information sufficient to build to.

A revised drawing was not always forthcoming, meaning we had to build to a combination of designs/ (descriptive) RFI's, only to then be issued with revised drawings [retrospectively]. This we believe is a failure on behalf of the client.  This has happened multiple times in the project. This has lead to misinterpretation of information and elements of re-work due to multiple elements of changes to designs, without up-to-date designs.

Question:
A - Are we write in thinking this is grounds for an NCE?
B - Under what CE criteria is this relevant? (CL. 60.1 (3)? (18)? )

Ultimately the Client has not undertaken their role in design management and has relied upon the contractor to clash detect, modify drawings on site based upon descriptive wording, and not followed it up until late on in the project.

Thanks.
