<p>Missed model changes cost you margin, meeting time and field labor. When a duct moves and nobody knows, your coordination meeting burns time finding out, and the work behind an unresolved clash stops. A clash caught in the model costs about $50. The same clash found in the field costs $5,000 to $50,000.</p> <p>BidLight closes that gap by keeping a record of every publish. Each one is a versioned snapshot, and any two revisions compare element by element, grouped by category: structural, MEP, envelope, interior. You see exactly what changed, when, and who owns the fix. No more reconstructing history from PDFs or chasing issues across Teams, email and Bluebeam.</p> <p>Issues are pinned to the elements they concern and carry the sheet and revision they came from. Owners get a 6am digest of what is assigned to them, so the missed change gets caught before it reaches the field.</p>
