Pre-Bid Review GCs Use to Quantify Risk Instead of Padding Contingency
Generic contingency is what you pad when you can't see the risk. Helonic shows you the risk, item by item.
Every GC carries bid contingency, but the smart ones know the difference between contingency that's quantified and contingency that's padded. 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 Helonic helps
Quantified bid risk register
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 most pre-bid review under-delivers
GC estimators have 5–10 days to review thousands of pages of bid documents. 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.
GC pre-bid workflow
Upload bid documents on receipt
Drawings, specs, and addenda all indexed together.
Run comprehensive risk analysis
Findings ranked by potential cost impact.
Inform bid contingency by line item
Quantified risk replaces generic contingency padding.
Document priced risks
Risk register saved as audit trail for post-award scope disputes.
Example issues Helonic catches
Real-world issues detected by AI analysis, specific to general contractors running pre-bid review:
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
Key features for this workflow
Specific bid risk identification (not generic categories)
Order-of-magnitude cost estimation per finding
Sub-trade scope boundary clarification
Existing condition ambiguity surfacing
Quantity reconciliation against drawings

What construction professionals told us
“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.”

FAQs
How does this compare to having more estimators?
It's complementary. 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?
Yes - particularly well, 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?
A 500-sheet bid set runs in 1–3 hours. Findings are usable from the moment the analysis starts; comprehensive analysis completes well within typical bid timelines.
