Your 3d printer doesn’t have other utilities to accommodate. The printing is basically just the walls. Every other utility (Power, water, sanitary, HVAC, foundations, windows, doors, metal fabrications, networking etc) are all still done by people, all made with options made by other manufacturers.
Your printer also uses quick setting thermoplastic, not a concrete slurry that needs to set over the course of days instead of fractions of a second.
This and typical FDM printing are related, but truths about printing our a plastic trinket don’t necessarily translate to large concrete structures.

Just coming from a civil engineering/construction perspective, the straight lines are probably more about alignment. In these kinds of buildings (and considering US zoning laws that require a certain amount of parking), sometimes the alignment is critical to ensuring the building, parking, and drive-through fit. Straight lines are easy to measure, draw, and check in the field. Not to mention the actual way these 3D printing concrete machines work. The ones I’ve seen online are on some kind of track, and these ones are no different. From the looks of it, they’re kind of set up like those cranes you see at shipyards: youtube.com/shorts/igQ9G_Brkl8
