<p>You stop it by letting the estimate follow the model instead of the other way around. When your cost number updates itself, there is no ping-pong left to play.</p> <p>Here is how it works with BidLight, inside Revit:</p> <ol><li>Export your model. BidLight reads the geometry and metadata, no separate takeoff.</li><li>Get your numbers back in minutes: labor, equipment, material, and time costs.</li><li>Change the design. The estimate updates in real time, so the number matches what is actually on screen.</li><li>Trust the line items. Two AI models classify your BOQ at 86% accuracy, with pricing pulled from a large cost database plus Craftsman, 1Build, and RSMeans.</li><li>Track it as it moves. The Kanban board uses the same material, equipment, and labor predictions, so progress and resources stay in one place.</li></ol> <p>The headache you are describing is chasing scattered updates and redoing takeoffs every time the design shifts. BidLight kills the redo. One export, and the estimate stays tied to the model.</p> <p>If you would rather not run it yourself, BidLight also does the BIM work for you, including 4D and 5D.
