<p>A clash costs more in the field because by the time it is found, work is installed and crews are standing by. In the model, moving a duct away from a pipe costs about $50 of someone's time. On site, the same clash means ripping out work, re-sequencing trades and paying idle labor, which runs $5,000 to $50,000.</p> <p>BidLight keeps the problem in the model. It runs inside Revit and Navisworks, so you publish straight from the federated model. Every publish is a versioned snapshot, and any two revisions compare element by element. Issues are pinned to the elements they concern and live in one place, not scattered across Teams, email and Bluebeam.</p> <p>A 6am digest shows each owner the issues assigned to them. Nobody has to dig through PDFs or guess who moved what, and closing an issue needs proof against the model.</p> <p>You catch clashes before they reach the field, and labor keeps moving.</p>
