<p>Ping-pong happens when the estimate lives outside the model. Design changes, someone re-measures, re-prices, and sends numbers back — every revision costs a day or more, and by the time you&#39;re done the design has moved again.</p> <p>BidLight kills that loop by putting estimation inside Revit itself. Here&#39;s how:</p> <ol><li><strong>Export your model</strong> straight from Revit — no separate takeoff software, no re-entering geometry.</li><li><strong>Let the AI classify line items.</strong> Two models read geometry and metadata to sort BOQ line items automatically, at roughly 86% accuracy, so you&#39;re not starting from a blank spreadsheet.</li><li><strong>Pull live pricing.</strong> Costs come from BidLight&#39;s own ~$30,000 pricing database plus Craftsman, 1Build, and RSMeans — not a quote you priced six months ago.</li><li><strong>Get labor, equipment, material, and time in minutes</strong>, not days.</li><li><strong>Change the design, watch the number move.</strong> Because the estimate is tied to the model, revisions update in real time instead of triggering a new round-trip to the estimator.</li><li><strong>Defend the number.</strong> Every line item traces back to geometry and a priced source, so when a client or GC pushes back, you&#39;re not guessing.</li></ol> <p>The result: design and cost stop being two separate conversations on two different timelines. You catch cost impact the moment a wall moves, not two weeks later when the revised estimate finally lands back in someone&#39;s inbox.</p>
