<p>Buying material you won&#39;t use comes from guessing quantities off takeoffs that fall behind the design. BidLight cuts that guesswork by forecasting material needs straight from your Revit model, so you order closer to what the job actually requires and waste less.</p> <p>Here is where the keyword fits. What is 5D BIM cost estimation? It is tying cost to your model&#39;s geometry and metadata, so quantities and prices stay linked to the design instead of living in a separate spreadsheet. When the model changes, the numbers move with it.</p> <p>That link is what stops over-ordering. BidLight&#39;s two AI models read geometry and metadata to classify BOQ line items, then pull current pricing from its database plus Craftsman, 1Build, and RSMeans. You get material, labor, equipment, and time costs in minutes, and the figures update in real time as the design shifts.</p> <p>A few things to know:</p> <ol><li>Export your Revit model into BidLight.</li><li>Let the AI classify line items and forecast material quantities.</li><li>Review the costs pulled from live pricing sources.</li><li>Change the design and watch the quantities and numbers refresh.</li></ol> <p>The payoff is plain. You stop chasing scattered updates, order materials against real counts, and carry numbers you can defend into the bid.</p>
