<p>BidLight helps you catch a missed clash by tracking every model change and every clash or issue between revisions, pinned to the elements involved. It does not rely on someone remembering what moved.</p> <p>Every publish from Revit or Navisworks becomes a versioned snapshot. Compare any two revisions and you see the differences element by element, grouped by category: structural, MEP, envelope, interior. When a duct run moves into a beam&#39;s space, that change shows up in the diff instead of hiding in a 90-minute meeting.</p> <p>What to do when you spot one:</p> <ul><li>Open the revision comparison and trace the change back to the elements driving it.</li><li>Pin an issue to those elements. It carries the sheet and revision it came from.</li><li>Assign an owner. They see it in their 6am digest.</li><li>Close it only with proof: screenshots, sign-off and the linked model commit.</li></ul> <p>A clash caught in the model costs about $50. The same one found in the field costs $5,000 to $50,000.</p>
