<p>It&#39;s the story behind why BidLight exists: a design change slips through after the estimate is locked, nobody catches it, and the number that goes out the door is wrong. Most firms find out at closeout, when the $170k gap becomes a real loss instead of a near miss.</p> <p>Here&#39;s how it stays a near miss with BidLight:</p> <ol><li><strong>Export the model, not a snapshot.</strong> You pull labor, equipment, material, and time costs straight from Revit, so the estimate is tied to the actual model, not a PDF someone printed last week.</li><li><strong>The AI reclassifies as geometry changes.</strong> Two models read geometry and metadata to classify BOQ line items at 86% accuracy, so a wall that moved or a system that got added doesn&#39;t get missed.</li><li><strong>The number updates in real time.</strong> When the design changes, the estimate changes with it. No one has to remember to re-run a takeoff.</li><li><strong>Pricing comes from a live database.</strong> Roughly $30,000 in current pricing data plus Craftsman, 1Build, and RSMeans keeps the cost side honest, not stale.</li><li><strong>You can defend the number.</strong> Every line item traces back to geometry and a priced source, so when a client or PM asks &quot;where did this come from,&quot; you have an answer.</li></ol> <p>The mistake that never happened isn&#39;t a fluke. It&#39;s what you get when estimates stay attached to the model instead of living in a spreadsheet someone forgot to update.</p>
