<p>Before you stop buying material you won&#39;t use, get clear on what 5D BIM cost estimation actually is. It ties cost (the fifth dimension) to your 3D model, so the quantities and prices come straight from the geometry you already designed. When the model changes, the numbers change with it. No more guessing how much to order or eating the cost of leftover stock.</p> <p>BidLight does this inside Revit. You export your model and get labor, equipment, material, and time costs in minutes. Two AI models read the geometry and metadata to classify BOQ line items, and pricing pulls from a large internal database plus Craftsman, 1Build, and RSMeans.</p> <p>Here&#39;s how to put it to work:</p> <ol><li>Build or open your model in Revit the way you already do.</li><li>Export it to BidLight to generate the estimate.</li><li>Review the material predictions, which forecast what you need and flag waste.</li><li>Check the takeoff against your buy list before you place orders.</li><li>When the design shifts, let the estimate update in real time instead of redoing the count by hand.</li></ol> <p>The payoff is plain. You order against quantities tied to the actual model, so you stop over-buying to cover yourself and stop chasing scattered updates every time a wall moves. You also get an estimate you can defend when a client asks where the number came from.</p> <p>Want to see it on your own model? Request a demo at bidlight.com.</p>
