Pre-Bid Review That Quantifies Risk Instead of Padding Contingency
Helonic is an AI construction drawing analysis platform for Estimators doing Pre-Bid Review.
Sharpen your bid by understanding what's actually in the documents - and what isn't.
What is pre-bid review for estimators?
Pre-bid review for estimators is the risk pass Helonic runs on scope gaps, quantity mismatches, and unassigned equipment before the bid number is turned in. A thorough review identifies specific risks the bidder can either price into the bid or exclude explicitly; a rushed review leads to generic contingency that either overbids (lose the project) or underbids (lose money). Helonic gives estimators thorough review in hours instead of days - usable even on tight bid timelines.
Why do estimators run out of time on bid review?
Estimators run out of time on bid review because they have 5 to 10 days to cover thousands of pages of bid documents. The time pressure forces tradeoffs - either depth on a few critical areas or breadth at lower depth. Helonic reads the full set in the bid window, so the estimator does not have to choose between a few sheets done carefully and the rest skipped.
How does Helonic help estimators with pre-bid review?
Helonic names the specific bid risks, such as a flooring section in the spec with no flooring on the architectural sheets, instead of folding them into one allowance.
Named risks, not a lump contingency

Quantified cost impact
Each finding carries a rough dollar swing so contingency is assigned to a line, not a percentage.
Sub-trade scope clarity
Work sitting between two trades is listed so the estimator can say which subcontract carries it.
Quantity reconciliation
Quantities in the bid form are checked against the drawings, including counts that do not match the plans.
What issues does Helonic catch in pre-bid review for estimators?
Helonic flags these pre-bid review issues when estimators review a set:
Equipment OFOI/CFCI status not noted in mechanical schedule - pricing 14 RTUs as OFCI vs. CFCI is ±$280,000 swing
Spec section 09 67 23 (resinous flooring) in spec manual but no resinous flooring on architectural sheets - scope unclear
Existing pavement removal at parking expansion ambiguous - partial vs. full removal ~$45,000 difference
Steel quantity in takeoff 47 tons but Helonic recomputation from drawings estimates 52 tons - bidder will pad ~$25,000
Controls scope at VAV boxes between MC and EC unclear - ~$25,000 boundary item
Demolition limit at existing tree T-12 ambiguous - protect-in-place vs. removal differs by ~$8,000 plus replanting

How do estimators perform pre-bid review with Helonic?
Helonic indexes the drawings, specifications, and addenda the day the bid set arrives.
Upload bid documents at receipt
Helonic indexes the drawings, specifications, and addenda the day the bid set arrives.
Rank findings by bid-day cost
Each gap is ranked by what it would swing the bid, such as owner-furnished rooftop units versus contractor-furnished units.
Inform bid by line item
The estimator prices the specific line, or excludes it in the proposal, instead of burying it in one contingency.
Document priced risks for audit
The priced risks are saved so the project manager can see, after award, what the bid actually carried.
What do practitioners say about pre-bid review for estimators?
“The estimators we talked with - including at top-25 ENR contractors and at mid-market GCs - all described pre-bid review as the work that most often determined bid quality. The estimators who could be thorough on every set were the ones who won consistently. Helonic was the tool that made thoroughness affordable on every bid.”

What do estimators ask about pre-bid review?
How does this compare to historical takeoff databases?
Helonic complements rather than replaces takeoff databases. The takeoff gets you quantities; Helonic gets you the risks the quantities don't capture.
Does it work on hard bid public projects?
Helonic works particularly well on hard bid public projects, because public-project documents tend to have more scope gaps and harder constraints on contingency.
Can it integrate with our bid tools?
Helonic exports findings in CSV and PDF formats compatible with most bid management tools. Direct integrations available for some platforms.
