<p>Your Revit model is the design intent. What gets built is whatever the field interprets from drawings, RFIs, and change orders — and that gap is exactly where estimates go stale.</p> <p>BidLight closes it by pricing off the actual model, not a static takeoff done weeks ago. Here&#39;s how that works in practice:</p> <ol><li><strong>Export straight from Revit</strong> — no separate takeoff software, no re-entering quantities by hand.</li><li><strong>Two AI models classify each BOQ line item</strong> by reading geometry and metadata, at roughly 86% accuracy — so line items reflect what&#39;s actually modeled, not a guess.</li><li><strong>Pricing pulls from a live database</strong> of around $30,000 in reference costs, blended with Craftsman, 1Build, and RSMeans data, so labor, equipment, and material costs stay current.</li><li><strong>Change the design, and the numbers update in real time</strong> — move a wall, resize a duct run, swap a system, and your cost estimate moves with it instead of waiting for the next manual pass.</li><li><strong>Use the updated numbers to defend your bid</strong> — when a client or GC questions a line item, you&#39;re pointing to a model-driven estimate, not a spreadsheet from three revisions ago.</li></ol> <p>The honest caveat: BidLight prices what&#39;s in the model. Field conditions, substitutions, and undocumented scope changes still need to get modeled or flagged before the number reflects them. That&#39;s also why BidLight offers done-for-you BIM services — execution plans, 4D/5D, and fabrication detailing — to help keep the model itself closer to what&#39;s actually going to be built.</p>
