The construction industry is booming, thanks to an increase in housing and commercial building demand—but the US economy is shaky at best. Modular construction is rising in popularity thanks to its ability to reduce waste, cut supply costs, and accelerate project timelines. To keep pace with growing demand, the industry must find ways to streamline processes across all fronts. Modular construction companies like Cassette, Z Modular, Katerra, and ReMo Homes are at the forefront of boosting efficiency thanks to their innovations in the modular construction space.
