S-Squared officially unveiled its ARCS technology in December and, at the time, said the machine could be used to build all types of structures — residential, commercial and infrastructure — from 500 square feet to 1 million square feet in size. In addition to the benefits of speed and lower costs, S-Squared said the machinery can be set up on a jobsite in as little as six hours, can withstand severe weather and that the resulting structures will last 100 years, even if exposed to water, fire and mold.
