<p>Usually because nobody told them the model had moved, or they could not tell which revision was current. A wall shifts in Revit, and most teams find out at the next coordination meeting or when someone re-exports and re-checks. The trade kept building from what they had.</p> <p>BidLight keeps one live record of the project inside Revit and Navisworks. Each publish is a versioned snapshot, so the current revision is never a guess. Compare it with the one the trade worked from and every changed element shows up, grouped by structural, MEP, envelope and interior.</p> <p>Then close the loop:</p> <ul><li>Pin an issue to each affected element, with the sheet and revision attached.</li><li>Assign the trade as owner. They see it in the 6am digest.</li><li>Close it only with a screenshot, a tagged user and the linked model commit.</li></ul> <p>A conflict caught in the model costs about $50. Once the trade has installed against the old revision, it costs $5,000 to $50,000.</p> <p>Plans run from Basics at $260 per license per year to Max at $590, with unlimited projects and custom Enterprise pricing.</p>
