<p>BidLight catches it by tracking every model change between revisions, pinned to the elements, so you see the problem while it is still a fix in the model. It runs inside Revit and Navisworks, and you publish straight from the model. Every publish is a versioned snapshot, and any two revisions compare element by element, grouped by structural, MEP, envelope and interior.</p> <p>Each morning by 6am you get a digest of the issues assigned to you and anything due within three days. Issues live in one place, not scattered across Teams, email and Bluebeam. Each one carries the sheet and revision it came from, so you know who moved what and where the clash sits.</p> <p>Closing an issue needs proof: screenshots, a sign-off and the linked model commit. That keeps problems from being marked resolved when they are not.</p> <p>A clash caught in the model costs about $50. Found in the field, it costs $5,000 to $50,000. Catch it before the meeting does.</p>
