Subcontractor proposals are rarely formatted the same way. One bidder may include labor and material together, another may separate them, and a third may carry allowances or exclusions that materially change the number. Bid leveling creates a common comparison before the GC makes an award decision.
Start with the same scope
Build a scope checklist from the drawings and specifications before comparing prices. Include the major work items, accessories, equipment, testing, cleanup and temporary requirements that belong in the package. The goal is not to make every subcontractor price identical; it is to make the differences visible.
Check inclusions and exclusions
Read the proposal notes, not only the total. Look for exclusions, owner-furnished items, delegated design, freight, taxes, permits, startup, controls, insulation, firestopping and other handoff points. A low proposal can become a different number once missing scope is carried into the comparison.
Normalize quantities and alternates
Compare the bidder's quantities against the GC takeoff where practical. Then separate base bid, alternates, allowances and unit prices. Keeping those categories distinct makes the final estimate easier to audit and revise.
Document the leveling result
A useful leveling sheet records the original proposal, scope adjustments, clarifications and normalized comparison. That record gives the project team a clear basis for the award and makes later questions easier to answer.
Final checklist
- Same scope basis for every bidder
- Exclusions and clarifications reviewed
- Quantities checked against drawings
- Alternates and allowances separated
- Outliers investigated before award
- Final comparison saved with the bid file
