Answered: NEC3 ECC: Is there a provision in the NEC for a Contractor to be paid an advance payment for a provisional sum item in the boq?

NEC does not provide for provisional sums. The Works Information should be clear as to what is required so that it can be programmed and priced.

If the Employer is not sure what is required then he should set out clear assumptions in the Works Information that can be programmed and priced and should the assumptions change then the CE process kicks in.

There is provision under X14 for advanced payments.
