<p>It survives because every number in it traces back to something a reviewer can check.</p> <p>Most estimates get gutted in Value Engineering because the numbers are unlabeled guesses — nobody can say where a labor rate or material cost came from, so the room defaults to cutting scope. BidLight builds the defense into the estimate itself:</p> <ul><li><strong>Pricing you can point to.</strong> Costs come from a live database of roughly 30,000 pricing points plus Craftsman, 1Build, and RSMeans data — not a rounded number someone remembers from the last job.</li><li><strong>Classification tied to the model.</strong> Two AI models read your Revit geometry and metadata to classify BOQ line items directly from what&#39;s actually drawn, so quantities match the design instead of a spreadsheet someone eyeballed.</li><li><strong>Numbers that move with the design.</strong> When VE proposes a swap — a different wall assembly, a smaller mechanical room — the estimate updates in real time instead of forcing a manual re-take of the whole model.</li><li><strong>A trail, not a guess.</strong> Because each line item is generated from the model plus a priced database, you can walk into the meeting and show your work instead of defending a hunch.</li></ul> <p>That&#39;s the real difference in a VE meeting: it&#39;s not about having a lower number, it&#39;s about having a number nobody in the room can poke a hole in. Estimates built on scattered spreadsheets and last quarter&#39;s memory don&#39;t hold up under that kind of scrutiny. Estimates built on current pricing and live model data do.</p>
