I recall the form saying "estimated" completion date. What can you get away with with "estimated"? The contractor is telling us that the Indoor Air Quality testers say they have to test before the completion date. I find this difficult because the estimated competition date was turned in the deign submission. Our completion date is estimated to be 1 month past what was originally submitted. Not sure what to do here...Can we change the dates in the Construction Review on PIf4?
