Introduction to Modular Construction
Modular construction is a method of building structures off #
site in a controlled environment before assembling them on-site. This process involves constructing individual modules or sections of a building in a factory setting and then transporting them to the construction site for final assembly. Modular construction is gaining popularity in the construction industry due to its numerous benefits, including cost savings, faster construction timelines, reduced waste, and increased quality control.
