<p>When the model and the drawings don&#39;t match, you can&#39;t prove which version was coordinated. That becomes a legal problem fast. Every BidLight export is versioned and diffed element by element, so you always know who changed what, when, and why. You also get a daily digest at 6am of the issues you own. If a clash sits unresolved, the work behind it stops. That&#39;s $15K to $50K in field labour standing idle every week. Three weeks of that costs more than BidLight does for the year. So the risk isn&#39;t just lost hours. It&#39;s a claim you can&#39;t defend and a field crew standing around. BidLight runs inside Revit and Navisworks, so the record lives where the model lives. You publish straight from the model or the federated model. When someone asks what changed between exports, you have the answer, not a side by side PDF comparison. Plans run from $260 per licence per year. No new tools to learn. Just a record you can hand to a lawyer, an owner, or your own PM without guessing.</p>
