The re-submission bottleneck in permit review wastes weeks of project schedule. Reviewers manually diff drawings to verify changes, a repetitive, error-prone task that adds no value. This workflow automates that diffing, using version control and computer vision to isolate modified elements. It then triggers focused, automated re-checks only on those deltas, generating a precise delta report. This cuts re-review cycle time by over 70%, accelerating project starts and reducing consultant fees spent on administrative back-and-forth.
