Normalize the scope before looking at the total
Create one comparison row for each major work item: mobilization, traffic control, milling, removal, base repair, asphalt placement, markings, and closeout. Enter the quantity and specification proposed by each bidder beside that item.
If one contractor measured a different area or assumed a different milling depth, the totals are not yet comparable. Ask for clarification instead of adjusting the number yourself.
Checklist
- Square yards or other quantity used for each work area
- Milling depth and treatment at curbs, structures, transitions, and drains
- Asphalt mix, lift thickness, and number of lifts stated in the proposal
- Locations and quantity basis for full-depth repair
Separate certainty from allowances
Some conditions cannot be fully confirmed until pavement is removed. A responsible proposal should explain how uncertain work will be measured and approved. Put allowances, unit prices, and alternates in separate columns so they do not disappear inside the base total.
Ask what evidence will support a change: field measurements, owner approval, photographs, tickets, or testing. The objective is a predictable decision process, not a promise that unknown conditions will never occur.
Compare the operating plan
A bid for an occupied shopping center, school, industrial site, or municipal street should explain how work areas will be released, protected, and reopened. Review the proposed sequence against deliveries, tenant peaks, pedestrian routes, emergency access, and other contractors.
Schedule length alone is not enough. Confirm whether the proposed duration assumes full closure, night work, weekend work, or uninterrupted access to areas the owner cannot actually release.
Use a final clarification sheet
Before award, send each finalist the same unanswered questions and record the written responses. Incorporate agreed clarifications into the contract documents so the final scope is not split between an estimate, emails, and verbal discussions.
Checklist
- Scope and quantity differences resolved
- Exclusions and owner responsibilities confirmed
- Phasing and access assumptions accepted
- Change-authorization process documented
- Required closeout items included
