How to compare contractor bids fairly
The lowest number is not always the lowest cost. Level the bids to the same scope before you compare.
The lowest number is not always the lowest cost. Level the bids to the same scope before you compare.
Start with the same documents
Every bidder should receive the same drawings, specification, addenda and bid form, and be told the same bid date. Answer questions in writing to all.
Level the scope
- List what the documents require.
- Mark each bid as included, excluded or unclear for each item.
- Ask bidders to price or confirm the unclear items.
- Convert allowances and alternates to a like-for-like total.
Use the scope comparison worksheet.
What to compare besides price
- Schedule and start date.
- Payment terms and retainage.
- Who pays for permits, inspections and testing.
- Insurance and warranty.
- Key personnel and references.
- Exclusions and qualifications.
Watch for
A bid far below the others may have missed scope. Ask about it before award rather than after. Heavy allowances can hide costs that return as change orders.
After the choice
Record the agreed scope and clarifications in the contract. See comparing supplier quotations for materials.
