<p>It means everyone on the job is working from the same cost picture, not five versions of it.</p> <p>When you estimate inside Revit with BidLight, labor, equipment, material, and time costs come from one model export. The number is built from the geometry and metadata, so it traces back to what the design actually shows. When the design changes, the number updates in real time. You are not stitching together a takeoff from one person, pricing from another, and a schedule from a third.</p> <p>So handing the GC one coordinated number means handing them a figure where the quantities, the pricing, and the timeline all agree. The BOQ line items are classified by two AI models reading the model at 86% accuracy, and pricing pulls from a large cost database plus Craftsman, 1Build, and RSMeans. That is a number you can defend when they push back.</p> <p>What the GC gains:</p> <ul><li>One source instead of scattered spreadsheets that drift apart</li><li>Costs that move with the design, so no stale figures slip into the bid</li><li>A clear line from each cost back to the model element it came from</li></ul> <p>The headache this kills is the version problem. No more chasing which takeoff is current or redoing the math after a design tweak. The GC gets a single coordinated estimate, and when something shifts, the whole number shifts with it.</p>
