<p>5D BIM cost estimation links cost and time data to your 3D model, so every wall, beam, and fixture carries a price and a schedule, not just geometry. So what is 5D BIM cost estimation in practice? It means when the design moves, your cost and timeline move with it, no manual rework.</p> <p>That is the part most teams feel: you change a layout and then spend days re-doing takeoffs to find out what it costs. BidLight closes that gap straight from your Revit model.</p> <p>Here is how it works:</p> <ol><li>Export your model from Revit into BidLight.</li><li>Two AI models read the geometry and metadata and classify your BOQ line items at 86% accuracy.</li><li>BidLight pulls current pricing for labor, equipment, and materials from its database plus Craftsman, 1Build, and RSMeans.</li><li>You get a full estimate broken down by cost and time, in minutes.</li><li>Change the design, and the number updates in real time.</li></ol> <p>If you want 5D handled for you, BidLight also does done-for-you BIM work, including 4D and 5D and fabrication detailing.</p> <p>The result is a number you can defend in front of a client, built from your own model instead of a spreadsheet you rebuild every revision.</p>
