<p>Change a layout and you get a new number in minutes, not a re-takeoff.</p> <p>BidLight keeps one live record of the project inside Revit and Navisworks. You export your model and it returns labor, equipment, material, and time costs. When the design changes, the number updates in real time. No side-by-side PDF comparison, no chasing who moved what across Teams, email, and Bluebeam.</p> <p>Here is what happens when the layout shifts:</p> <ol><li>Change the layout in your model.</li><li>Export straight from Revit or the federated Navisworks model. Every version is versioned and diffed element by element.</li><li>Two AI models read the geometry and metadata, classify the BOQ line items, and refresh pricing.</li><li>Send the updated number to your client or GC with the backup behind it.</li></ol> <p>The cost impact lands in minutes because pricing pulls from a roughly $30,000 database plus Craftsman, 1Build, and RSMeans. Classification runs at 86% accuracy, so you are reviewing line items, not rebuilding them.</p> <p>That is the point. You stop re-doing takeoffs and start sending numbers you can defend. Turn early estimates into something you bill for.</p>
