<p>You catch a finish swap by comparing the revision the moment it is published, not after it is installed.</p> <p>Swaps cause trouble because nobody re-checks the model fast enough to see the impact before the crew mobilizes. BidLight closes that gap:</p> <ul><li><strong>Change the model, not a spreadsheet.</strong> BidLight runs inside Revit, so the record is not a separate task someone forgets.</li><li><strong>Compare the revisions.</strong> The interior category shows the swapped elements, and the structural and MEP categories show whether anything behind them moved too.</li><li><strong>Pin an issue.</strong> It carries the sheet and revision, so the trade sees exactly what changed.</li><li><strong>Assign an owner.</strong> The 6am digest puts it in front of them.</li><li><strong>Close with proof.</strong> Screenshot, tagged user and the linked model commit.</li></ul> <p>The fix is not catching the swap after the fact. It is making a revision comparison part of approving the change.</p>
