<p>The version nobody talks about is the one that answers who changed what, when, and why.</p> <p>BidLight runs inside Revit and Navisworks. Publish straight from the model, and every export gets versioned. Then it diffs element by element. So the export from Tuesday does not sit next to the PDF from Monday while your team squints at both.</p> <p>What that kills is the two hour coordination meeting spent finding out a duct moved. And the issue that lived in Teams, email, and Bluebeam where nobody could find it. Digests go out by 6am so you own your list daily.</p> <p>The money part: every week a clash sits unresolved, work behind it stops. That runs $15K to $50K in field labor standing idle per week. Three weeks costs more than BidLight does for the entire year.</p> <p>So the model version nobody talks about is the one with a record. Not a folder of PDFs.</p>
