ICC/MBI Standards for Off-Site Construction
Published in 2021 in partnership with the ICC, these off-site standards bring clarity to the off-site and modular construction processes.
This first edition standard provides planning and preparation requirements such as: the role of the architect/modular manufacturer/construction manager/general contractor, location of plant vs. construction site, and material procurement and lead times.
ICC/MBI 1200-2021 includes requirements for:
- A controlled manufacturing environment.
- Supply chain integration.
- Structural modular vs. nonstructural modular.
- The fabrication process and on-site assembly.
The scope of this first edition standard is to provide minimum requirements to safeguard the public health, safety and general welfare and address societal and industry challenges for the inspection and regulatory compliance of off-site and modular construction. It addresses the inspection, approval and regulatory compliance of off-site residential and commercial construction components as well as their assembly and completion at the final building site.
