<p>A messy renovation model doesn&#39;t disqualify a bid, but it does change how you work it. Existing conditions rarely match reality, so treat the model as a starting point, not gospel.</p> <p>Here&#39;s how to approach it in BidLight:</p> <ol><li><strong>Export what you have.</strong> Even an incomplete or dirty Revit model gives BidLight&#39;s AI something to classify. The two models read geometry and metadata to tag BOQ line items, so partial data still produces a usable baseline.</li></ol> <ol><li><strong>Flag the unknowns.</strong> Renovation scopes almost always carry demo, hazmat, or hidden-condition risk that no model captures. Note these separately so they don&#39;t get buried in a clean-looking number.</li></ol> <ol><li><strong>Let pricing do the heavy lifting.</strong> BidLight pulls current labor, equipment, and material costs from its ~$30,000 pricing database plus Craftsman, 1Build, and RSMeans, so at least the cost side of a messy scope stays defensible even when the geometry isn&#39;t perfect.</li></ol> <ol><li><strong>Update as the model gets cleaned up.</strong> As your team fixes families, walls, or MEP that were modeled wrong, BidLight&#39;s estimate updates in real time, so you&#39;re not re-running takeoffs from scratch every revision.</li></ol> <ol><li><strong>Use the 86% classification accuracy as a check, not a verdict.</strong> Spot-check flagged line items, especially in areas where the model is known to be rough.</li></ol> <p>If the model needs real cleanup before anyone can bid it confidently, that&#39;s exactly what BidLight&#39;s done-for-you BIM services (execution plans, 4D/5D, fabrication detailing) exist for.</p>
