<p>It survived because it was built to be argued with, not just admired.</p> <p>A VE meeting kills line items that feel soft — round numbers, vague scopes, prices nobody can trace. BidLight estimates hold up because every number is grounded in geometry pulled straight from the Revit model, not eyeballed off a floor plan. The AI reads the actual quantities and classifies BOQ line items directly from the model, so the estimate isn&#39;t a guess dressed up as a number.</p> <p>Here&#39;s what usually gets it through the room:</p> <ol><li><strong>The quantities are model-derived.</strong> Nobody can shave 10% off a wall count that&#39;s pulled from the actual design.</li><li><strong>Pricing is sourced, not invented.</strong> Labor, equipment, and material costs come from a current database plus references like RSMeans, Craftsman, and 1Build — so &quot;where&#39;d this number come from&quot; has a real answer.</li><li><strong>It updates live.</strong> When someone proposes swapping a system to save cost, the estimator can show the new number in minutes instead of promising a revised number next week.</li><li><strong>The backup is there.</strong> Because the estimate traces back to model geometry and sourced pricing, you can defend each line instead of hoping nobody asks.</li></ol> <p>That&#39;s the real value: it&#39;s not that the number is lower, it&#39;s that it&#39;s defensible. Estimates that can&#39;t explain themselves get cut first. This one explains itself line by line.</p>
