Off-Site Construction Solutions for Today’s Challenges

The building industry is facing multiple challenges, including workforce availability, housing affordability, job site safety, building quality and sustainability. The expanded use of off-site construction (often called modular or prefabrication) is one approach to address these challenges. The International Code Council’s Family of Solutions offers multiple solutions to support the safe and efficient use of off-site construction.

Design, Fabrication, Construction and Assembly

ICC/MBI Standard 1200: Standard for Off-Site Construction: Planning, Design, Fabrication, and Assembly

The International Code Council is partnering with the Modular Building Institute (MBI) in the development of a comprehensive standard to address all facets of the off-site construction process including: planning; designing; fabricating; transporting; and assembling commercial and residential building elements. This includes componentized, panelized and modularized elements. This standard will not apply to HUD Manufactured Housing or “tiny homes.” Learn More.

 

ICC G5-2019 Guideline for the Safe Use of ISO Intermodal Shipping Containers Repurposed as Buildings and Building Components

  • More than 30 million International Organization for Standardization (ISO) intermodal shipping containers are in use around the world today. These containers were built to ISO standards and maintained to standards defined by the International Maritime Organization’s (IMO) “Convention for Safe Containers.”
  • New or used, containers are now repurposed at a pace that makes their reuse a multi-billion-dollar global industry. Containers are regularly repurposed and converted into International Residential Code and International Building Code occupancy uses. As a building material, the applications are widely diverse as is the extent to which the container is used as a structural building element.
  • Local jurisdictions and state administrative programs are reacting to the growing trend of shipping container repurposing but can be behind in terms of regulations and compliance. This International Code Council Guideline is intended to help state and local jurisdictions as well as owners, architects, builders and engineers in their assessment as to how to design, review and approve shipping containers as a building element.
