A scope gap is any work the project needs that isn't priced by anyone — usually living in the white space between two trades or buried inside an exclusions list.

How do scope gaps become change orders?

Every gap that survives bid review reappears in the field as work that has to happen but wasn't paid for. The customer sees it as a change order; the GC sees it as eroded margin.

Can software find scope gaps automatically?

Yes — scope gap analysis tools compare every sub bid against the bid baseline and flag rows nobody priced, plus exclusions that conflict across trades.

Scope Gap Identification: A Field Guide for Estimators

Scope gaps are the silent margin killers of estimating. Every change order born after award started life as a scope gap nobody flagged during bid review. Here's how to find them on purpose.

What a scope gap really is

A scope gap is any work that needs to happen for the project to be complete that isn't priced by anyone. It usually lives in the white space between two trades — demo that the demo contractor assumes the GC handles, patching the framing sub assumes the drywall sub does, blocking the trim carpenter assumes the framer left behind.

Where gaps hide

Trade transitions: where one sub's work ends and another's begins.
Specialty inclusions: hoisting, dewatering, temp protection, fire watch.
Compliance: permits, inspections, testing, commissioning.
Allowances and alternates that quietly carry zero in the base bid.
Owner-furnished items that still need installation labor.

Re-read every 'Excludes' list out loud — exclusions are scope gaps with a label.
Tag each gap with an owner and a placeholder dollar value before sending your proposal.
