<p>Unresolved clashes get expensive because the work behind them stops while the crew waits. A clash caught in the model costs about $50. Found in the field, it costs $5,000 to $50,000 in rework and idle labor. An unresolved one can burn $15K to $50K a week.</p> <p>BidLight keeps one live record of the project inside Revit and Navisworks. Every publish is a versioned snapshot, and any two revisions compare element by element. Move a duct and you can see who moved it and when, without a long meeting to find out. Issues are pinned to the elements and carry the sheet and revision they came from. By 6am, each owner gets a digest of the issues assigned to them.</p> <p>Working blind is what gets expensive. A shared record of every change, with an owner on every issue, fixes that while there is still schedule to recover.</p>
