Using an Option A NEC4 contract: at pre contract the Contractor presented a VE option for a window design. The VE option was accepted informally by the Employer and contract agreed. However the contract drawings did not change to reflect the VE option. The Employer wants to revert back to the original design intent as per the contract drawings.
Does the contract drawing/scope take precedence over the pre contract VE option which was accepted but not formally recorded.
