the units shipped dry walled with even the bathrooms and kitchens done including the fridge, was crazy to watch they work nearly 24/7 with Washington ave closed from 12th to 13th for over a week.

It's called modular construction. Basically the same construction techniques and materials normally used on-site (framing, followed by plumbing/electrical rough-in, followed by insulation, followed by drywall and other finishes), but instead done in sections (modules) in a factory, and then installed and interconnected on-site on a conventionally constructed foundation. Works especially well when you have essentially self-contained units such as apartments. And if done right (i.e., interesting design and high-quality exterior finishes installed on-site), it can be indistinguishable from high-quality construction built entirely on-site.
Here are a couple of photos showing the process:
