The moment I saw drone mapping save a foundation pour on a tight downtown site
We were prepping a 12-hour concrete pour for a new apartment building in Nashville, and the survey stakes just didn’t line up with the site plan. The project manager pulled out a drone, flew it over the lot, and within 20 minutes we had a 3D map showing the sewer line was 2 feet off from where the old paper drawings said. Has anyone else had a close call like that caught by aerial tech?

Holy crap, 2 feet off? That's insane. I've seen survey stakes be off by a few inches before but never that bad. Would've been a nightmare digging up a brand new pour to fix that. Drones are a total game changer for catching that kind of stuff before it turns into a six figure mistake.

Can drones actually catch that before the concrete's even poured though?

Totally agree, that six figure mistake thing really hits home. Those paper drawings from the 70s might as well be treasure maps for all the good they do with modern sewer line shifts.
