Construction Bid Checklist: What Every MEP Estimate Must Include

Incomplete bids and missed scope items are among the most expensive mistakes in construction estimating. A systematic pre-submission checklist ensures every MEP estimate is complete, accurate, and defensible before you sign and submit.

Before You Start: Document Review Checklist

• Confirm you have the latest drawing set with all revisions and addenda
• Review all project specifications, especially Division 01 general requirements
• Check for design-build or performance specifications that shift design responsibility
• Identify owner-furnished equipment (OFE) and contractor-furnished owner-installed (CFOI) items
• Note any specified manufacturers or substitution restrictions
• Review the bid form for specific unit prices, alternates, or allowances required
• Confirm bid date, time, and delivery method

Frequently Asked Questions

How can I reduce estimating errors on repeat project types?

Build project-type-specific checklists based on your post-bid reviews. If you repeatedly miss fire alarm scope or equipment commissioning on medical office projects, add those items to your healthcare checklist.
