Frequently Asked Questions


We are using the NEC3 Engineering and Construction Contract (ECC) option A (priced contract with activity schedule) on a develop-and-construct project. If an instruction for additional works is given after the completion date, and the instruction changes the works information and is a compensation event, what effect does this have on the defects date?

Assuming completion of the whole of the works has been achieved, the instruction will have no effect upon the defects date. This is because the defects date is defined as being ‘xx’ weeks after completion of the whole of the works in the contract data part one.  Of course ‘xx’ is the number of weeks inserted in the contract data in your particular contract.  Completion is not affected as it has already been certified.  The value of the compensation event will have to reflect the additional defined costs to the contractor of carrying out and managing isolated works after its resources have left site.
