Let AI read sub bids and check them against your estimate
The problem
Sub bids arrive in every format, so estimators retype them into a bid tab and compare totals before scope. Zebel says leveling one trade by hand takes about an hour, across 100 to 200 bid reviews on a typical project, and an exclusion buried at the bottom of a quote can turn into a change order after signing.
How AI helps
AI pulls the line items out of each bid, shows the exact text every number came from, maps them onto the bid form tied to the live estimate, and flags scope a sub left out or excluded against the spec. Follow-up questions to subs are drafted for the estimator, and nothing moves into the budget until the estimator approves it.
