The architecture business model was built for a world where hours spent on the project equals value. AI doesn't work that way. -------- In this episode, I sit down with Martyn Day, journalist and publisher at X3DMedia — the company behind AEC Magazine and Develop3D — to dig into what it means when engineering automation, open SDKs, and Palantir-scale data plays arrive in AEC at the same time. Martyn has covered this industry for 37 years. He says this moment is categorically different from everything before it. MEP solvers can generate a complete electrical and mechanical layout overnight from a Revit file. Real-time FEA tools let structural analysis respond instantly to a floor plate move. AI can already replicate 70% of what a CDE does. And companies like Palantir aren't arriving to sell software — they're arriving to own the data layer between every downstream process, making everyone else just a pipe feeding their system. The billable hour model is in the crosshairs. So is the named user license. Martyn calls it the asteroid: the technologies are already visible on the horizon; the impact is still ahead of us. This conversation is for firm leaders, technology directors, and BIM managers who sense the ground shifting and need to understand what it means for their practice in the next 12 to 24 months. What you'll learn in this episode: • Why MEP solvers are compressing months of engineering coordination into hours — and what that does to how architects and engineers collaborate • How open SDKs are dismantling software moats, and which products (CDEs, clash detection, model checking) are most at risk • Why firms that own their data, clean it, and train on it will have advantages no vendor can replicate • What the UK engineering sector's apprenticeship collapse tells us about AEC's workforce future • Why we're at peak named user licensing, and how layered cloud and token costs are changing firm economics • How multi-agent systems represent the next wave — and why most firms aren't remotely prepared Chapters: 00:00 Introduction 00:02:50 How Martyn tracks AEC trends with AI agents 00:07:00 Engineering automation: MEP solvers and real-time FEA 00:10:20 AI and the architecture billable hour model 00:11:30 Palantir's AEC play and the end of software moats 00:15:00 Peak named user licensing and tokenization 00:17:40 Data sovereignty: why firms need to reshore their project data 00:22:20 Open SDKs and AI-written software 00:29:20 BIM 1.0 as a drawing conduit 00:38:30 Institutional knowledge drain and the people problem 00:41:10 The apprenticeship failure and AEC's next generation 00:50:40 Value-based billing and commoditization of design 00:54:40 Small teams competing with the largest firms 01:00:10 Autodesk's 2028 pricing wall 01:07:30 Mining your own data for competitive advantage 01:19:10 Token costs at scale and LLM selection 01:28:00 Multi-agent systems and governance structures 01:40:50 Sketch to 3D and the future of design ideation 02:10:00 The "anti-AI firm" and the future of practice size 👍 Like this episode if you're tracking what AI will actually do to how architecture firms work 💬 Drop a comment: which part of the AEC stack do you think is most at risk? 🔔 Subscribe for more conversations on architecture and technology 🌐 Explore more at [https://trxl.co](https://trxl.co/) #AECtechnology #architecturebusiness #BIMfuture #AIinarchitecture #Autodesk #AECindustry
