The short answer
The short answer
The approved whole-home baseline can provide a starting range from the opening count, with an approved location factor when one is available. A final proposal should still use an opening schedule that aligns product consistency, exceptions, installation method, repairs, finish work, phasing, access, and change-order rules.
Published ranges are national baselines or clearly identified geographic adjustments from the active Window Replacers pricing model.
