I think you'll be surprised about that. I'm not in the robotics field (though perhaps I should be) but at an earlier stage in life I spent several years on remodelling and building houses - as in swinging a hammer, not singing deeds and checks.

Repair/remodeling is challenging because you need (approximate) knowledge of construction techniques from across a 150 year timespan, buildings settle and change shape over time, and generally owners don't usually want the building completely gutted and rebuilt from scratch. But it's not that hard. New construction is relatively straightforward. The biggest challenges for construction robots will be handling dust/debris (25% of construction work is cleaning things up) and maintaining health and safety (of the robots themselves; self-preservation is a skill that has to be learned).

That said I don't think you'll see this with the current generation of humanoid robots. A lot of the design assumptions seem almost comically wrong to me.

Factory workers maybe but all processes have to be redesigned with design for robotic automation in mind. That will displace a lot of people and they will naturally go into the trades since the skills translate more easily so while I agree they wont be replaced there may be downward pricing pressure.

I hear China is doing a lot of this already to stave off their upcoming demographic collapse. I haven't seen raw details or videos though other than demonstration stuff (anyone have anything to share?)
