A robot is not only hardware. A robot is hardware and software. The robots in the links you posted are either not commercially available or not capable of working in an unrestricted construction environment. Such an environment do require a humanoid frame at this time because the entire world is geared to that. I agree that a few show promising demos, but that's not what I would "available". Perhaps I should have been more clear. Unless I(As in some rando corporation) can go out and buy it I don't consider it available.
