Ecologically correct - efficient factory production produces less waste in production, and cleaner installation does less harm to the natural environment of the construction site. Safer construction – modular construction has been proven to be safer than traditional masonry. Low labor requirements – teams for construction and finishing works when completing modular buildings include a smaller number of workers on the construction site Reduced costs of design fees – standardized details of modular buildings simplify and reduce the need for the participation of specialized disciplines.
