AI is not going to build and repair roads, or houses, or pretty much anything else physical any time soon, nor is it going to replace nurses, cooks, shop assistants, or any number of other occupations that require human interaction. Even the vast majority of assembly lines, warehouses, etc. still rely on human labour because turns out building and maintaining robots is expensive and difficult, and even the best robots are bad at manipulating the real world with the kind of flexibility a human can (AI, or lack thereof, is not the main bottleneck here). What you're talking about is the stuff of distant future speculative fiction that may or may not happen some day, but if it does it sure won't be heralded in by ChatGPT.
