<p>Stop the work that depends on the old revision and confirm what changed, before the crew installs something that no longer matches. Building from last month&#39;s steel model means rework on one of your biggest packages, and the cost shows up as idle crews and change orders.</p> <p>BidLight shows what moved without a meeting:</p> <ul><li>Publish the current Revit or Navisworks model. Each publish is a versioned snapshot with its own files, author and milestone.</li><li>Compare it to the revision the field is using. Differences appear element by element, with structural, MEP, envelope and interior broken out.</li><li>Pin an issue to every steel element that moved and assign an owner.</li><li>Owners see it in their 6am digest, so the fix does not wait for the next coordination meeting.</li><li>Close each issue only with a screenshot, a tagged user and the linked model commit.</li></ul> <p>The cost of a stale revision is not one wrong beam. It is a week of idle labour, $15K to $50K, while everyone works out which version is current.</p>
