Any savings from these bid costs may go back to the GC under the GMP - though the actual contract may differ. I'm simply speaking to the typical.

Ideally, changes are kept to a minimum after this point - but they are in essence inevitable. And every change incurs an added cost. In that instance the owner typically sets aside a Construction Contingency to cover these changes and for Errors & Omissions which also occur. This is usually around 3% of construction cost, but can be higher or lower.
