<p>A messy Revit model doesn&#39;t disqualify a renovation from getting a real number — but it changes how you prep before you export.</p> <p>Renovation models are notoriously inconsistent: elements missing types, phases not set, demo scope tangled with new construction. BidLight&#39;s two AI models read geometry and metadata to classify BOQ line items, and that accuracy depends on how much structure the model actually gives them to work with.</p> <p>Here&#39;s how to bid it without cleaning the whole file:</p> <ol><li><strong>Set phasing first.</strong> Even rough Existing/Demo/New phase assignments help the model separate scope instead of pricing everything as new work.</li><li><strong>Fix obvious category misses.</strong> You don&#39;t need a perfect model — just make sure walls are walls and doors are doors, not generic families.</li><li><strong>Export and run the estimate.</strong> Let BidLight generate labor, equipment, material, and time costs from what&#39;s there.</li><li><strong>Review the 86%-accuracy classifications.</strong> Spot-check line items in messier areas of the model — that&#39;s where misreads cluster.</li><li><strong>Correct and re-run.</strong> Because the number updates in real time as the model changes, fixes propagate through the estimate immediately.</li><li><strong>Cross-check pricing.</strong> Pull from the built-in database and Craftsman, 1Build, and RSMeans data to make sure renovation-specific costs look right.</li></ol> <p>If the model is beyond quick fixes, BidLight&#39;s done-for-you BIM services can build out execution plans or clean detailing so future estimates don&#39;t inherit the same mess. Either way, you&#39;re not stuck waiting on a full model cleanup to get a defensible number.</p>
