<p>A model version mismatch is a legal and financial risk because you cannot prove which version was coordinated, and a claim you cannot defend costs more than the lost hours.</p> <p>When the model and the drawings do not line up, the argument turns into who knew what, and when. BidLight answers that from the record. Every publish is a versioned snapshot with its own files, author and milestone, and any two revisions compare element by element. You always know who changed what, and when.</p> <p>Issues are pinned to the elements they concern and carry the sheet and revision they came from. Closing one requires proof: screenshots, user sign-off and the linked model commit. Owners get a 6am digest of the issues assigned to them, so nothing waits in an inbox.</p> <p>BidLight runs inside Revit and Navisworks, so the record lives where the model lives. You publish straight from the model or the federated one. When someone asks what changed between exports, you have the answer instead of a side-by-side PDF comparison.</p> <p>Plans start at $260 per licence per year for Basics. The result is a record you can hand to a lawyer, an owner or your own PM without guessing.</p>
