<p>Buying only what you&#39;ll actually install starts with a material count you can trust, and that comes from your model, not a spreadsheet rebuilt by hand.</p> <p>That&#39;s the real gap in bim vs traditional cost estimating in aec. Traditional takeoffs measure the drawings once, then go stale the moment the design moves. BidLight reads your Revit model and forecasts material needs from the geometry itself, so the quantities match what you&#39;re actually building.</p> <p>Here&#39;s how to get to a lean material buy:</p> <ol><li>Export your Revit model into BidLight.</li><li>Let the AI classify your BOQ line items and forecast material needs. It runs at 86% accuracy, so you start from a real count, not a guess.</li><li>Check the material list against your scope and trim anything the design no longer calls for.</li><li>Pull current pricing from the built-in database so your buy reflects today&#39;s costs.</li><li>Re-export when the design changes. The numbers update in real time, so your order quantities follow the model instead of lagging behind it.</li></ol> <p>The payoff is less waste and less cash tied up in material you&#39;ll never place. You order to the model you&#39;re building now, and when that model shifts, your count shifts with it. No redoing the takeoff, no chasing scattered revisions to find out what changed.</p>
