<p>Because modeling is table stakes now, and what separates candidates is telling the team what changed, fast. Every firm has someone who can build a clean Revit model. Fewer can answer what moved since the last issue without a two-week delay.</p> <p>A polished model with no change record loses to a rougher model backed by a clear one.</p> <p>BidLight closes that gap. Publish from Revit or Navisworks and each export becomes a versioned snapshot. Compare any two revisions element by element, grouped by structural, MEP, envelope and interior. The answer takes about 15 minutes instead of a 90-minute meeting.</p> <p>When the design changes, the record changes with it. You do not rebuild a list every time a wall moves, so you can show a client what a change touches in the meeting instead of promising a summary next week.</p> <p>The coordinator who can show what changed, who owns it and whether it closed with proof gets the call back.</p>
