Construction AI: the sector books time to argue where AI actually pays, and a map of what's buried before you dig

So, the trade calendar has finally caught up with the argument everyone's been having in the site cabin. On 2 September, UK Construction Week revealed the Digitalisation and AI Stage agenda for its Birmingham show (NEC, 29 September to 1 October, curated by Build in Digital and sponsored by Zutec), and the session titles tell you where the mood has moved. One is called "AI in Construction: Hype, Reality and the Next Five Years". Another, on the Tuesday, is "From Adoption to Acceleration: Helping Supply Chains Embrace AI Together". Read those two together and you get the shift: the question is no longer whether to use AI, it's where it earns its keep and where it's someone selling you a demo.

What the Wednesday session does is quieter and more useful. "Collaboration by Default: Digital Twins, the Golden Thread and Gateway 3" puts the data plumbing on the main stage rather than tucked in a corner. That matters, because a digital twin is only ever as good as the information feeding it, and most project information is still scattered across drives nobody fully trusts. The line-up backs the seriousness up. Kier's digital and data director Colin Bell, Travis Perkins' data integration and insights director Robert Barbour, and Dr Bola Abisogun OBE are among the speakers. Not a robot-head keynote in sight, which is progress on its own.

There's a third one I'd point a commercial lead at: "The Proof Clients Want: Turning Impact into Contracts". That's the session that decides budgets, because it's about turning what you did into evidence a client will pay for. If you're going, don't wander the floor picking up branded pens. Pick three sessions, take your own project numbers, and make someone on a stand walk you through the actual workflow rather than the sizzle reel. That's what it's about.

Over in the States, a company called CivilGrid raised a $26m Series A on 27 August, led by Spark Capital, to build what its founder calls a "Google Maps for the underground". Josh Mackanic is a former PG&E engineer, and the problem he's chasing is the one that ruins programmes quietly: you don't know what's buried until the excavator finds it. CivilGrid pulls together the scattered records (utility assets, land ownership, environmental constraints, other people's works) into one map you can scope a job against at the desk, before anyone's on site.

The claim doing the rounds is that on one project it headed off around $6m of rework. That's a vendor-reported figure and a single case, so I'd take the number with a fistful of salt, but the direction's right. What that means on a UK job is obvious the moment you've had a service strike or turned up a Victorian sewer nobody mapped: the cost isn't the survey, it's the day the whole gang stands idle while someone rings the statutory undertaker. It's a US product for now, and the data it leans on is US data, so this isn't a tool you'll buy in Basingstoke next week. But the shape of it, pulling buried-services risk forward to the desk stage, is exactly where the groundworks headache lives over here too, and it's where I'd expect a UK-facing version to find willing buyers.

Put the two together and the week has a spine. The conference stage is programming sessions about proving value and getting the data right; the money is flowing to a tool whose whole job is to know something before you commit to it. Same instinct, different end of the telescope. The discipline underneath both is dull, and it's the thing that pays: get your information straight, then let the machine work on it. A twin fed on rubbish is just an expensive rumour, and a takeoff run over records you don't trust is a bid you can't defend.

Today's action: pick one recurring decision on your current job that keeps going wrong for want of information you already own somewhere, and fix that information flow before you buy anything clever to sit on top of it. The tool's the easy part; the data is the job.
