On paper, and if all goes according to plan, modular construction should result in both time and cost savings. But modular techniques have not cracked the code fully on commercial, and other more complicated, construction types. Architects, consultants, general contractors, subcontractors need retraining, including how to monitor quality and track progress. Another challenge is the fact that the initial savings can often be wiped out by design, manufacturing or execution errors on site.
