Catch missing scope before award.
Scope gaps — work nobody bid — are the #1 source of unexpected COs. PreconIntel flags them at leveling time, not three months into construction.
A $20K scope gap really costs about $42K.
The direct CO amount is the number you see on the invoice. It's also the smallest part of what the gap actually costs you. Markup on a post-award change is 15–40% over what the work would have cost at competitive bid. Schedule impact adds general conditions burn. And the relationship cost with the owner doesn't show up on a P&L.
The six gaps we see on every other project.
Fire caulking
Drywall sub excludes it. Firestopping sub excludes it. Everyone assumes the other guy has it.
Blocking (wood + metal)
Framer doesn't bid finish-carpenter blocking. Finish carpenter doesn't bid framer's blocking. Nobody bids either.
Roof penetrations
Roofer excludes MEP flashing. MEP subs exclude roof repair. A $400 penetration becomes a $12K CO.
Equipment & housekeeping pads
Concrete sub excludes "anything that wasn't on the foundation drawings." MEP subs exclude "anything concrete."
Weather protection
Scattered across every trade's scope. Falls between the cracks until the first storm hits the partial shell.
Pressure-treated sills
Concrete contractor excludes wood. Framer excludes concrete contact. Six boards nobody bid.
Four overlapping layers of detection.
Tagged inclusions & exclusions
AI extracts each sub's inclusions, exclusions, and clarifications as structured tagged lists — not narrative paragraphs. Each tag maps to a CSI subdivision so the system knows what's actually covered.
Cross-sub gap detection
When the level sheet shows a CSI row where every sub is blank, that's a scope gap. When two subs explicitly exclude the same line and nobody includes it, that's a scope gap. Flagged before award.
Submission gates
Estimates can't leave your desk with known coverage holes. Submission gates block a bid packet from moving to senior review until every CSI division has at least one covering bid.
Historical pattern matching
PreconIntel knows fire caulking, blocking, and equipment pads are the canonical gaps. Every bid package gets explicit checks for the trades your project type typically misses.
