<p>Yes. That $1,500 door becoming a $7,500 problem almost always traces back to an estimate that stopped tracking the design. Someone swaps the door spec, adds hardware, or changes the frame detail, and the number on the bid stays frozen while the model moves on.</p> <p>BidLight is built to close that gap. It reads your Revit model directly, geometry and metadata both, and classifies BOQ line items automatically. When you change the design, the estimate updates in real time instead of waiting for someone to catch it manually and redo a takeoff.</p> <p>Here&#39;s what that looks like in practice:</p> <ol><li>Export your model from Revit into BidLight.</li><li>The AI classifies line items and pulls current pricing from BidLight&#39;s database and sources like RSMeans, Craftsman, and 1Build.</li><li>You get labor, equipment, material, and time costs in minutes, not days.</li><li>When the design changes, whether it&#39;s a door swap or a wall assembly revision, the estimate recalculates instead of sitting stale.</li><li>You bid with numbers that reflect what&#39;s actually in the model, not what was in it three revisions ago.</li></ol> <p>That&#39;s the real cost of a stale estimate: not the door itself, but everything that piles on around it, change orders, rework, and a bid that no longer matches the job. Keeping the estimate live with the design is how you catch that swing before it hits the field, and it&#39;s why the bid holds up when the project actually gets built.</p>
