To clarify further, my inquiry is in regard to the testing of material, and specifically the timely receipt of test certificates.
The item is clear when using Option B and D as the Method of Measurement for Highway works has a detailed ‘Item Coverage’ of what is included for each item of work (and testing is included here). Presumably the ‘Item’ is not ‘complete’ until evidence of the appropriate testing has been received by the Supervisor. The withholding of money can obviously encourage timely testing and reporting.to the Supervisor.
I’m not clear how testing is linked to a work activity under Option A and C, as opposed to being dealt with as a separate entity of work. i.e. the cost of testing (say concrete) is included when using a Bill of Quantity under the Method of Measurement for Highway Works, but isn’t linked so clearly under an Option A or C.
Basically, I don’t want to pay for the material (say Concrete) until I’ve received the appropriate test certificates.
