The trade press ran it under the headline "JPI Uses AI to Build Faster, Smarter." My first question was the one I ask every founder pitching me software. Compared to what? The article doesn't say. It was one pilot project, with no name, no unit count, and no baseline. Forty months against their own history? Against a 2022 job that sat around waiting on windows? Unknown. Then the recipe. A library of standard floor plans. Takt scheduling, which moves trades through a building on a fixed beat, floor by floor. A central office tracking every job site in real time. And AI. Standard plans and Takt were around long before ChatGPT. So how many of the 11 months in savings belong to the robot? JPI hasn't broken it out. That matters, because months don't cost the same. A month of early design, before you close on the land, costs some architect invoices and a few lunches. A month at the end of construction, on a $75 million deal with a 65% loan at 8%, costs about $325,000 in interest alone, before taxes, insurance, lost income, and what the investors are owed. Guess which phase the design library lives in. And if the project is waiting on the city, finishing drawings faster just gets you to the city's waiting room sooner. The scheduling claim I buy. Their Takt schedules run 15,000 to 20,000 lines. Building one used to take three people four weeks. Now it's one person, three or four days. That's planner hours, not calendar months. But if cheap scheduling is what makes a 20,000-line plan practical at all, it's a real edge. You can do plenty of this now with little risk and no AI. Pick a floor plan and stop changing it. I've paid for my share of "quick revisions." I can't remember one that was quick. Start the permit conversation before the drawings are done. Put your GC in the room before the design is locked. The AI debate has two loud teams right now. One credits it with every month a project saves. The other says it can't count the windows. This story sits somewhere in the middle, next to a binder of floor plans the architect isn't allowed to touch. So next time somebody tells you AI saved them a year, ask two questions. Compared to what? And which months?
