Pre-Bid Review GCs Use to Quantify Risk Instead of Padding Contingency
Helonic is an AI construction drawing analysis platform for General Contractors doing Pre-Bid Review.
Generic contingency is what you pad when you can't see the risk. Helonic shows you the risk, item by item.
What is pre-bid review for general contractors?
Pre-bid review for general contractors is a document-risk pass on the bid set so estimators can price specific gaps, ambiguities, and trade-boundary items instead of padding a generic contingency. Quantified contingency comes from understanding specific risks in the documents - undimensioned connections, ambiguous existing conditions, sub-trade scope boundaries. Padded contingency comes from not knowing where the risk is. Helonic surfaces specific risks so your contingency reflects what's actually in the documents.
How does Helonic help general contractors with pre-bid review?
Each finding scored by potential change order cost so the estimator knows where the real risk concentration is.

Competitive bidding advantage
Understand the documents better than competitors. Surface scope gaps others will miss.
Post-award protection
Document the items you priced explicitly so you're protected when scope disputes arise.
Bid turnaround speed
Comprehensive risk assessment in hours instead of days - usable even on tight bid timelines.
Why does pre-bid review under-deliver for general contractors?
Pre-bid review under-delivers for general contractors because estimators have 5–10 days to read thousands of pages and spend that time on quantities they can price quickly. They focus on the items they can quantify quickly - quantities, easily-priced scopes, and obvious risks. The harder-to-spot risks - sub-trade boundary ambiguities, undimensioned connections, missing details - get less attention and end up in generic contingency. Helonic targets exactly those harder-to-spot risks.

What issues does Helonic catch in pre-bid review for general contractors?
Helonic flags these pre-bid review issues when general contractors review a set:
Equipment OFOI/CFCI status not noted in mechanical schedule - pricing 14 RTUs as OFCI vs. CFCI is ±$280,000 swing
Existing pavement removal limit at parking expansion ambiguous - partial vs. full removal differs by ~$45,000
Connection at beam-to-existing-column at grid C referenced but not detailed - likely $15,000–$40,000 fabrication scope dispute
Controls scope at VAV boxes not allocated between MC and EC - ~$25,000 boundary item
Concrete strength on foundation plan f'c=4000 psi but spec calls f'c=5000 psi - material cost differs ~$8/CY
Fire damper count on FP drawings (47) doesn't match mechanical penetration count (61) - ~$14,000 scope gap

What do practitioners say about pre-bid review for general contractors?
“The general contractors we interviewed all described the same thing: the bid that won and held was the one where the estimator understood the documents better than competitors. Helonic is leverage on exactly that - understanding the documents at the depth a thorough senior estimator would, in the time available.”

What do general contractors ask about pre-bid review?
How does this compare to having more estimators?
Helonic is complementary to adding more estimators. Helonic handles the comprehensive document analysis; your estimators focus on judgment, market pricing, and sub-trade relationships.
Does it work on hard-bid public projects?
Helonic works particularly well on hard-bid public projects, because public-project bid documents tend to have more scope gaps and harder constraints on bid contingency padding.
What's the typical bid-time runtime?
Helonic runs a 500-sheet bid set in 1–3 hours. Findings are usable from the moment the analysis starts; comprehensive analysis completes well within typical bid timelines.
