<p>Model changes are exactly what BidLight is built to catch.</p> <p>Because BidLight runs inside Revit and reads geometry and metadata straight from your model, your estimate isn&#39;t a static file you build once and hope stays accurate. Change a wall assembly, swap a finish, resize a room, and the labor, equipment, material, and time numbers behind it update in real time — no re-running a takeoff from scratch, no forgotten line item quietly wrong on bid day.</p> <p>Here&#39;s how it works in practice:</p> <ol><li><strong>Export your Revit model into BidLight.</strong> Two AI models scan the geometry and metadata to classify BOQ line items automatically, at roughly 86% accuracy.</li><li><strong>Get priced numbers in minutes.</strong> Costs are pulled from BidLight&#39;s own ~$30,000 pricing database plus Craftsman, 1Build, and RSMeans — not a spreadsheet someone updated three months ago.</li><li><strong>Keep working in Revit as usual.</strong> Design changes, value engineering, client revisions — make them where you already work.</li><li><strong>Watch the estimate move with the model.</strong> BidLight recalculates costs as the design evolves, so you always know what the latest version actually costs.</li><li><strong>Review the delta before you bid.</strong> Catch the cost impact of a change immediately, instead of discovering it after submission.</li></ol> <p>The point isn&#39;t just speed — it&#39;s defensibility. When your numbers track the model instead of a snapshot in time, you&#39;re not chasing scattered updates or re-explaining why the estimate is stale. You&#39;re bidding what the design actually is, right now.</p>
