<p>Because the client sees the effect of their own change before they leave, which moves the conversation from whether they can trust you to what happens next.</p> <p>BidLight works from the model you publish from Revit or Navisworks. Compare the revision before the change with the one after, and you see the differences element by element, grouped by structural, MEP, envelope and interior. That is what lets you show a change in the room instead of promising a follow-up next week.</p> <p>It holds after the meeting too. Pin an issue to each affected element and it carries the sheet and revision, so what you showed stays true.</p> <ul><li>Open the comparison on a laptop during the walk-through, not a PDF from last week.</li><li>Talk through the categories so the client sees where the change lands.</li><li>Assign owners on the spot and let the 6am digest carry them forward.</li><li>Follow up in writing within the hour.</li></ul> <p>About 15 minutes with the comparison replaces a 90-minute meeting.</p>
