<p>Everyone downstream is working from a drawing that just went stale. The duct, the sleeve, the hanger layout: any of it may now clash, and nobody knows until the field finds it.</p> <p>BidLight makes the move visible the day it is published:</p> <ul><li>Publish the new model from Revit. It becomes a versioned snapshot with its own author and milestone.</li><li>Compare it against the previous revision, element by element, grouped by structural, MEP, envelope and interior.</li><li>Pin an issue to each element the move touches. The issue carries the sheet and revision it came from.</li><li>Assign owners. They see their items in the 6am daily digest.</li></ul> <p>You see what the wall touched in about 15 minutes instead of a 90-minute meeting. A conflict caught in the model costs about $50. Found in the field it costs $5,000 to $50,000.</p>
