As a high-end residential GC, I'm very interested in this product. We have incorporated Leica Totalstation and BLK360 into our projects. It assists confirming layouts, as-built conditions, and communicating with design professionals working remotely.

I am an architect who worked as a contractor and as a consultant and I made an account here just to comment on this. When you found out the builders did that, what you should have done is stopped the work and have them correct their mistake on their own dime. This is an unforgivable mistake and a team of professional should never make something like that. Obviously I am not in your shoes, but this is insane to me. An…
We discovered/noticed this when the exterior walls were 2 meters high. They had to move around interior walls but that didn't help much. My wife and I concluded that we got what we paid for, and you're right that in hindsight we should have taken legal action against the contractor. I don't know how breaking down the whole exterior of a house to fix it down to the foundation would feel though. At some point we though…
The foundation would be a pain in the ass but ultimately, as others have stated, that's kind of not your problem.

Cool! From HP! The robot only costs $1,500 but a two pack of extra sharpies for it costs $48,000. Before you can use it, you must install 5 petabytes of HP drivers.
Joking aside, I don't believe HP developed this product, they almost certainly bought the company that makes it. My hunch? Seen these things before. I doubt it has been DRMd to hell yet, and I doubt they upgraded to show PC LOAD LETTER at all times, but why did they add this to their portfolio?

You have adjusts due to its detectors and it has a prism on it and is being continuously tracked by a total station. It can correct course due to deviations in floor surface or obstructions pretty well.
The concern is not the course, but the ability to adjust a layout due to deviations from the plan due to normal construction errors. For example a pipe might not be in the location shown on plan for many reasons ranging from simple human error to a delta between the plan location when the pipe was layed and the time the robot got its data…keep in mind that when the pipe went in there was only dirt, not anything to ac…
But at that point it's back to engineering to figure out what to do (leave the pipe where it is and adjust around it _or_ move the pipe - possibly cutting concrete and perhaps untensioning/retensioning post-tensioned cables at substantial delay/cost) or move the piece of equipment that the penetration is serving.
One nice thing about automation like this is that the "as built" plans are more likely to be accurate because the only way to get "the computer" and "the robot" to stop squawking is to change the plans they are operating off of.
If this can't handle dirt surfaces, future generations/models probably will if there's demand. Perhaps such models would use spray paint/stencils or driving pins into the ground for marking purposes (or something more practical - I'm a software guy and this sounds like a hardware problem!).
My experience is with small residential builds but I would hope on large projects the location of each "unmovable" pipe/conduit etc that will end up penetrating a slab is already carefully verified before the next step is taken (such as placing concrete). Hopefully this is done with a total station rather than guys with chalk lines and tape measures. But a solution like this could reduce manual checking mistakes (of course, it's less likely to result in an experienced subcontractor noticing that the plan must be wrong because there's no reason for a conduit for 1KV electrical cables to come up 2cm away from a toilet trap in a multi-stall public bathroom - GIGO).
I could have benefited from this in the construction of our house. Riddled with inaccuracies, the engineer signed off on the foundations, but we found out when the walls were up that the builders used the internal dimensions as exterior dimensions. So our house is smaller by ~250mm on each side. We had to make so many compromises and wastages as a result. Bathrooms now smaller if we want to keep other rooms the same,…

Well, it definitely is. Now you’ve probably got to wait for a lawsuit to settle and then the work to be redone. Even in the absolute best case, this puts the project behind by months, and that’s if they don’t contest it.
