Off-Site and Modular Standard Consensus Committee
(IS-OSMC)
Off-Site and Modular Consensus Committee
(ICC 1200, 1205 & 1210)
Abstract: These comprehensive Standards 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, inspection, approval and regulatory compliance of off-site residential and commercial construction components and their assembly and completion at the final building site. Also included is permitting, in-plant and on-site final inspections, third party inspections; the role of Industrialized Building Departments, state modular programs and the Authority Having Jurisdiction. In addition, requirements for the energy efficiency and water conservation of off-site construction projects and the planning, designing, fabricating, transporting, and assembling, of commercial and residential building mechanical, electrical and plumbing (MEP) system elements. This includes the componentization and modularization of elements of MEP systems, the incorporation of MEP systems in componentized, panelized or modularized building elements, and the achievement of energy efficiency and water conservation requirements in off-site construction. These standards will not apply to HUD Manufactured Housing.
Background (Needs Statement): The lack of uniformity on how off-site construction is handled, the confusion across participants in the building process, and the hesitancy within the code official community reinforces the need for development of common criteria in the form of a standard to offer a path to compliance necessary to support the off-site construction industry including the MEP system elements, energy efficiency and water conservation.
