In our March/April 2026 cover story, the Agentic future of BIM, I argued that the shift from modelling to execution will require BIM platforms to manage delegated authority, not just geometry. Since then, a Google DeepMind paper, entitled ‘Intelligent AI Delegation’ has made that argument uncomfortably specific. To be clear, the paper doesn’t mention the AEC industry. Instead, it focuses on a higher level, and in particular, on how AI might be trusted to solve problems and provide reliable outputs.
