<p>Then you close the gap fast. Publish the new model to BidLight and compare it with the revision the trade worked from. Every publish is a versioned snapshot, and any two revisions compare element by element, so you see exactly what the trade missed.</p> <p>The workflow:</p> <ul><li>Publish the current model from Revit.</li><li>Compare it with the previous revision and read the changes by category.</li><li>Pin an issue to each element where the trade&#39;s work no longer fits. The issue carries the sheet and revision.</li><li>Assign the owner, and let the 6am digest keep them on it.</li><li>Close each issue with a screenshot, a tagged user and the linked model commit.</li></ul> <p>Speed matters here. A clash caught in the model costs about $50. Once a trade installs against the old revision, the same clash costs $5,000 to $50,000, and the crew behind it can sit idle.</p>
