<p>Send the live model instead. A PDF freezes one version and hides every change after it. When somebody moves a duct, the PDF you sent is already old, and you&#39;re the one explaining why the numbers don&#39;t match.</p> <p>BidLight keeps one live record of the project inside Revit and Navisworks. You publish straight from the model or the federated model. Every export is versioned and diffed element by element. So when the design changes, the estimate updates in real time and the number you hand over is the number on the screen.</p> <p>Here&#39;s what that looks like week to week:</p> <ol><li>Export from Revit or Navisworks. No separate takeoff pass.</li><li>Get labor, equipment, material and time costs in minutes.</li><li>Let the two AI models read geometry and metadata to classify BOQ line items at 86% accuracy.</li><li>Pull current pricing from the roughly $30,000 database plus Craftsman, 1Build and RSMeans.</li><li>Republish when the model changes and the diff shows what moved.</li></ol> <p>You stop arguing about which file is current. You show it. Plans run $260 to $590 per licence per year, and three weeks of unresolved clash at $15K-$50K a week costs more than the whole project.</p>
