How to Level General Contractor Bids Using a BOQ
The lowest number on a bid tab isn’t always the best value — and you can’t tell the difference without leveling every bid against the same measured scope.

What Bid Leveling Actually Means
Bid leveling is the process of adjusting and comparing multiple contractor bids so they can be evaluated against the exact same scope, quantities, and assumptions — rather than simply comparing bottom-line totals that may each be based on subtly different interpretations of the work. Without leveling, the “lowest bid” might just be the bid that quietly excluded the most scope.
Done properly, bid leveling doesn’t just identify the best price — it surfaces which bidders understood the project correctly and which ones are likely to generate change orders once construction begins, because their pricing reveals gaps or misunderstandings in scope.
Why a Standardized BOQ Is Essential
Bid leveling is only possible when every bidder prices against the same document. If each general contractor is left to estimate quantities independently from the drawings, their bids will differ not just in rate but in underlying quantities — making it nearly impossible to isolate whether a price difference comes from a lower rate, a lower quantity assumption, or an outright scope exclusion.
A shared BOQ removes that variable entirely. Every bidder prices the same measured quantities, so any difference in their total price comes down to rate, productivity assumption, or markup — exactly the variables an owner actually wants to compare.
The Bid Leveling Process, Step by Step
Build a leveling spreadsheet with every BOQ division as a row and every bidder as a column, then transcribe each bidder’s priced total for each division into the matching row. Immediately, outlier divisions — where one bidder’s number is dramatically higher or lower than the others — become visible and worth a direct follow-up question before award, rather than a surprise discovered mid-project.
Where a bidder submitted qualifications or exclusions alongside their bid, note them directly against the relevant division so their true cost impact is visible in the leveling matrix, not buried in a separate cover letter that gets forgotten by award time.

Red Flags That Signal a Risky Low Bid
Unusually Low Single Division
One division priced far below every other bidder often signals a missed scope item or a misunderstood quantity, not genuine efficiency.
Vague or Missing Qualifications
A bid with no exclusions listed at all is sometimes less careful, not more complete — worth a direct follow-up conversation.
Aggressive General Conditions
Unrealistically low general conditions pricing often signals a contractor planning to recover margin through change orders later.
No Contingency Line
A bidder carrying zero contingency on a project with real design uncertainty is either extremely confident or hasn’t fully considered the risk.
A Worked Leveling Example
Say three bidders return totals of $2.15M, $2.05M, and $1.88M for the same project. On the surface, the third bidder looks like the clear winner. But leveling their division-by-division pricing against the BOQ reveals their concrete division is priced 30% below the other two bidders, despite identical measured quantities — a strong signal of either a pricing error or a missed scope item within that division, not a genuinely lower cost basis.
A quick clarification question to that bidder, referencing the specific BOQ concrete items, either resolves the discrepancy with a legitimate explanation or reveals a real problem before contract award — exactly the kind of risk a leveling exercise against a shared BOQ is designed to catch early.
Beyond Price: Other Factors to Weigh
A properly leveled BOQ comparison gives you the clearest possible view of price, but price alone shouldn’t be the only award criterion on most projects. Contractor experience with similar scope, financial stability, proposed schedule, and safety record all matter — a leveled low bid from a contractor without the capacity or experience to deliver the project reliably isn’t actually the best value, even if the number looks best on the tab.
Use the BOQ-based leveling exercise as the foundation for an informed conversation, not as the sole automatic decision rule. The goal is an award decision made with full visibility into what each price actually represents — which a shared, measured BOQ makes possible in the first place.

Frequently Asked Questions
The process of adjusting and comparing contractor bids against the same scope and quantities, so price differences reflect rate and markup rather than differing scope assumptions.
Because bidders may have priced different quantities or excluded different scope, a bottom-line comparison can mislead you into thinking the lowest total is the best value when it may simply reflect the smallest scope.
A single division priced dramatically below every other bidder on identical measured quantities — it almost always deserves a direct clarification question before award.
Not automatically — leveling clarifies price comparison, but experience, capacity, schedule, and safety record all remain relevant factors in a sound award decision.
Note them directly against the relevant BOQ division in your leveling matrix so their true cost and scope impact stays visible through to award.
Not reliably — without a shared measured document, you can’t isolate whether price differences come from rate, quantity, or scope exclusion.
