Why This Tool Exists

The Problem

General contractor estimating teams manually read specification books and drawing sets to build scopes of work, then compare incoming trade bids line by line to check coverage. The process is slow, error-prone, and scope gaps discovered after award become costly change orders.

The Solution

AI models extract scope items from uploaded specifications and drawings, generate trade packages, and level submitted bids against the extracted scope to flag gaps and exclusions. The vendor claims 98% match accuracy, scope ready in under an hour, and roughly 50% time savings in preconstruction.
