How do I build a bid review checklist that catches missed costs?

Why bid reviews matter

Most estimating misses are not caused by one giant mistake. They come from small omissions that stack up: a missed accessory, an undercounted labor allowance, a vague scope note, or a markup rule applied inconsistently.

A good bid review checklist is not paperwork for its own sake. It is a practical filter that catches the same recurring mistakes before they become margin problems.

The real cause of missed costs

Estimating mistakes often happen because the team focuses on quantity and price, but not on completeness. A bid can look polished and still leave out:

• scope exclusions that should have been clarified
• small materials and consumables
• labor for access, staging, or cleanup
• subcontractor quote gaps
• overhead and profit assumptions
• risk items tied to phasing or conditions

A checklist works when it is built around these failure points.

A simple review structure that works

1. Start with scope coverage

Ask: did we actually price everything in the drawings, specs, and addenda?

Check for:

• addenda incorporated
• alternates included or excluded correctly
• missing plan sheets or detail references
• spec items not shown clearly on drawings
• exclusions that need to be stated

2. Check quantity and production assumptions

Ask: are the quantities right, and are the labor assumptions realistic for this site?

Check for:

• duplicate or missing counts
• unusual access conditions
• phased work or occupied-space constraints
• overtime or shift work
• productivity impacts from weather, logistics, or sequencing

3. Review material completeness

Ask: did we include the parts that always get forgotten?

Check for:

• fasteners, hangers, supports, sealants, trims, or accessories
• waste factors where appropriate
• delivery or freight if your pricing method includes them
• vendor quote gaps

4. Review subcontractor and vendor quotes

Ask: are we comparing quotes on the same scope basis?

Check for:

• exclusions in vendor quotes
• scope gaps between trades
• expiration dates
• lead time risks
• whether alternates were included consistently

5. Confirm markup and fee logic

Ask: did we apply overhead and profit the same way we intended to?

Check for:

• direct costs versus burdened labor
• consistent markup rates
• contingency treatment
• bond or insurance items, if applicable

6. Require a final red-flag pass

Ask: what looks too cheap, too fast, or too optimistic?

A final sanity check often catches the most expensive mistakes because experienced reviewers know when a bid feels unrealistically lean.

Make the checklist short enough to use

A checklist is only useful if your team will actually run it. Keep it to 10-15 items and organize it in the same order every time.

A strong bid review checklist usually includes:

• scope complete?
• addenda included?
• key quantities checked?
• labor assumptions reviewed?
• accessories and small materials included?
• vendor quotes aligned?
• markup confirmed?
• exclusions stated?
• risk items flagged?
• final margin sanity check completed?

How to make it team-proof

The goal is not to make one person smarter. It is to make the process consistent.

To do that:

• assign ownership for the review
• define what gets checked at each stage
• reuse the same review order every time
• save comments on what was missed after each job
• update the checklist based on real mistakes, not theory

That last step matters most. The best checklist is one that evolves from your own closeout lessons.

Where OneEstimate helps

OneEstimate supports this kind of workflow because it keeps estimates in a cloud environment with reusable item data and shareable budget links. That makes review easier than chasing spreadsheet versions around by email.

For a bid review process, the benefit is practical:

• reviewers can see the current estimate
• line items and assumptions are easier to revisit
• item libraries help standardize repeated pricing
• budget approval can happen without exporting multiple files

Bottom line

A bid review checklist should catch the mistakes that repeatedly hurt margin: missed scope, unrealistic labor, incomplete materials, quote gaps, and inconsistent markup. If you keep it short, repeatable, and based on your own closeout data, it will actually get used.
