I don't know, if you have time and robots, you could dig large holes and if you can make some kind of concrete out of regolith that might do the trick. It'll take years of constant effort that no human could do and involves tech we haven't invented yet, but tech we hadn't invented yet in 1960 actually got us to the moon.

My point is it will take a long, long time if it can be done at all and it cannot be done by humans working on the moon
