<p>The design-to-estimate ping-pong happens because your model and your budget live in two different places. Someone changes a wall, a window count, a duct run — and the estimate doesn&#39;t know until someone remembers to tell it. That&#39;s the loop BidLight is built to break.</p> <p>BidLight lives inside Revit. You export your model, and it reads geometry and metadata directly — no separate takeoff, no re-keying quantities into a spreadsheet. Two AI models classify your BOQ line items automatically, pulling current pricing from BidLight&#39;s own database plus Craftsman, 1Build, and RSMeans.</p> <p>Here&#39;s what actually changes:</p> <ul><li><strong>The estimate updates with the design.</strong> Revise the model, and labor, equipment, material, and time costs update in real time — not after a re-export and a re-send.</li><li><strong>No more chasing versions.</strong> You&#39;re not asking &quot;which set is this priced off?&quot; because the number is always tied to the current model.</li><li><strong>Estimators get their time back.</strong> Minutes instead of a slow manual takeoff means you can turn around revisions the same day they come in.</li><li><strong>The number holds up.</strong> Because pricing is grounded in current market data, you can defend it when a client or GC pushes back.</li></ul> <p>The result: instead of a slow handoff between design and estimating, you get one number both sides trust, updating as fast as the design does. That&#39;s what lets early estimates become something you can actually bill for — not a courtesy you redo for free every time the drawings move.</p>
