<p>Because the schedule is where a lot of your value hides, and most firms give it away for free.</p> <p>Hand a client a cost number and that&#39;s table stakes. Hand them a defensible timeline tied to that cost and you&#39;re selling insight they can act on. That&#39;s billable work.</p> <p>If you&#39;re wondering how does ai estimate construction costs from revit models, here&#39;s the short version: you export your model, two AI models read the geometry and metadata, classify your BOQ line items at 86% accuracy, and pull current pricing. You get labor, equipment, material, and time in minutes. The time piece is the part you can package.</p> <p>A few ways to bill for the schedule:</p> <ul><li>Turn your early estimate into a 4D/5D deliverable. BidLight does done-for-you 4D/5D and execution plans if you&#39;d rather not build it in house.</li><li>Charge for the live updates. When the design changes, the number and the timeline move with it, so you&#39;re not redoing takeoffs every revision.</li><li>Sell scenario comparisons. Show the client what a design choice does to both cost and calendar.</li></ul> <p>The cost answers what will it run. The schedule answers when do I get my building and what slips if we change course. Clients pay for the second question. Bill for it.</p>
