<p>If you cannot link the fix to a model commit, you can&#39;t bill it. BidLight versions every export inside Revit and Navisworks, then diffs the model element by element. So when a change order comes up, you point to the commit, show what moved, and prove the work was done.</p> <p>Here&#39;s how it works on your side:</p> <ol><li>Publish straight from the model in Revit or the federated model in Navisworks.</li><li>Every export is versioned and diffed element by element.</li><li>Issues are tracked and you get a daily digest of what you own by 6am.</li><li>When the question comes, pull the commit, show the geometry and metadata change.</li></ol> <p>That 86% accuracy classification and the pricing database run on that same record. You stop chasing scattered updates across Teams, email, and Bluebeam. The fix is documented. The change order is billable. And you keep the retainage you earned.</p>
