<p>Not quite clash detection in the traditional sense. BidLight isn&#39;t a coordination tool that flags MEP-vs-structural collisions. What it does is keep your cost model honest as the design changes, so budget problems surface the moment they happen instead of after you&#39;ve built and re-taken-off the whole thing.</p> <p>Here&#39;s how it actually works:</p> <ul><li>You export your Revit model into BidLight.</li><li>Two AI models read the geometry and metadata and classify BOQ line items at 86% accuracy.</li><li>Pricing comes in from BidLight&#39;s own database of roughly $30,000 in current rates, plus Craftsman, 1Build, and RSMeans.</li><li>You get labor, equipment, material, and time costs back in minutes, not days.</li><li>When the architect or engineer changes the design, your estimate updates in real time. No re-running takeoffs from scratch.</li></ul> <p>That real-time link is the real win. The moment a wall moves or a spec changes, you see the cost impact immediately, not three weeks later when someone&#39;s reconciling the budget against the latest drawing set. That&#39;s what stops the &quot;surprise in the budget&quot; problem: you&#39;re never estimating against a stale model.</p> <p>If you also need geometric clash checking (MEP routing, structural conflicts), that sits outside BidLight&#39;s core estimation product. What BidLight does own is making sure your numbers never fall behind the design, so you catch cost overruns before they hit the field, not after.</p>
