You'll almost never get to build the nexus or obsidian gates as the mechanos because it's on the magic techline, something that the mechanos shouldn't really be on past alteration/elementalism/necromancy/divination.
However I think the railroad improvement is the remedy for this - it requires refined mana, so it's pretty much mechanos exclusive and units get a big movement boost on it. It's not quite the same as the airlift buildings but I think it fits the mechanos better than such buildings.
