Introduction
In February of 2019 the International Code Council (ICC) and the Modular Building Institute (MBI) initiated a joint project to write standards for the planning, design, fabrication, assembly, inspection and regulatory compliance of off-site and modular construction. A standard development committee was created by the ICC Board of Directors in July 2019, and the first meeting of that committee was in October of 2019. The scope of this standard is to provide minimum requirements to safeguard the public health, safety, general welfare and address societal and industry challenges in multiple facets of the off-site construction process, including planning, designing, fabricating, transporting and assembling commercial and residential building elements.
Off-site construction techniques continue to gain favor among contractors as a departure from conventional construction processes. The off-site industry has evolved from a re-locatable modular manufacturing sector into more of a building delivery sector. In the simplest of terms, off-site (or modular) construction entails the planning, design, fabrication and assembly of building elements at a location other than the location where they were fabricated. Large components of a structure can be assembled in a factory-like setting and transported to the building site for final assembly. Subsequently, the finished construction is required to comply with the model building code adopted by the local authority having jurisdiction. This 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, engagement early on in the process, material procurement and lead times. This Standard also provides requirements for a controlled manufacturing environment, supply chain integration, structural modular vs. nonstructural modular (e.g., bathroom pods), the fabrication process and on-site assembly such as: staging area for construction materials, foundation, placing modules, structural connections, utilities (PMG) and weather considerations.
Development
This is the first edition of the International Code Council® (ICC®) and Modular Building Institute’s (MBI) Standard for Off-Site Construction: Planning, Design, Fabrication and Assembly. This standard was developed by the ICC/MBI Off-Site and Modular Construction Standard Consensus Committee (IS-OSMC) that operates under ANSI Approved ICC Consensus Procedures for the Development of ICC Standards. The consensus process of ICC for promulgating standards is accredited by ANSI. The Off-Site and Modular Construction Standard Consensus Committee, identified as IS-OSMC, is a balanced committee formed and operated in accordance with ICC rules and procedures.
The meetings of the ICC/MBI IS-OSMC Consensus Committee were open to the public and interested individuals and organizations from across the country participated. The technical content of currently published documents on off-site and modular construction, including documents of the National Institute of Building Sciences (NIBS) and American Institute of Architects (AIA), was reviewed and considered by the committee. The information from these documents helped form a basis for the regulations installed in this standard, but the exact provisions adopted by the committee were determined based upon the scope and intent of this standard. The requirements of ICC/MBI 1200 are based on the intent to establish:
• Provisions consistent with the scope of the ICC family of codes and standards, which are written to adequately protect public health, safety and welfare.
• Provisions that do not necessarily increase construction costs.
• Provisions that do not restrict the use of new materials, products or methods of construction.
• Provisions that do not give preferential treatment to particular types or classes of materials, products or methods of construction.
Adoption
ICC/MBI 1200, Standard for Off-Site Construction: Planning, Design, Fabrication and Assembly is available for adoption and use by jurisdictions throughout the United States. Its use within a governmental jurisdiction is intended to be accomplished through adoption by reference in accordance with proceedings establishing the jurisdiction’s laws. At the time of adoption, jurisdictions should insert the appropriate information in provisions requiring specific local information, such as the name of the jurisdiction.
Ordinance
The International Codes® (I-Codes®) are designed and promulgated to be adopted by reference by ordinance. Specific ICC Standards may also be adopted by reference by ordinance. Jurisdictions wishing to adopt the 2021 edition of ICC/MBI 1200, Standard for Off-Site Construction: Planning, Design, Fabrication and Assembly as an enforceable regulation governing structures and premises should ensure that certain factual information is included in the adopting ordinance at the time adoption is being considered by the appropriate governmental body. The following sample adoption ordinance addresses several key elements of a code adoption ordinance, including the information required for insertion into the code text.
