<p>Moving a door 12 inches gets expensive because every trade that depends on that opening has to move too: duct, pipe, conduit and framing. If nobody flags the change, you find out at the coordination meeting or in the field. Then you lose days re-coordinating and ripping out installed work. A clash caught in the model costs about $50. In the field it costs $5,000 to $50,000.</p> <p>BidLight catches that change early. Every publish is a versioned snapshot, and any two revisions compare element by element. When the door moves, you see exactly what changed and who changed it, without comparing PDFs or digging through email.</p> <p>Here is what you do next:</p> <ul><li>Publish your model from Revit or Navisworks.</li><li>Check the 6am digest for issues assigned to you.</li><li>Review the comparison to see what moved.</li><li>Pin an issue to the affected elements and assign it to the right trade.</li><li>Close it only with proof: screenshots, sign-off and the linked model commit.</li></ul> <p>You stay ahead of the change instead of behind it.</p>
