A convergence of procurement reform, pending national interface standards, and an overhaul of federal acquisition rules is accelerating modular and offsite construction adoption across U.S. public works programs in 2026. The changes are pushing modular suppliers, prefabrication vendors, and general contractors to align with unified requirements for Building Information Modeling (BIM) interoperability, supply-chain resilience, and component standardization - while agencies seek faster delivery and greater cost predictability.
Background
The push to standardize offsite construction has been building for years, driven by persistent labor shortages and chronic schedule overruns in conventional site-built delivery. The Associated Builders and Contractors estimates the industry must attract at least 500,000 new workers annually to meet current demand, a gap that modular factory production is increasingly expected to help bridge. The U.S. modular construction market reached $20.3 billion in 2024, approximately 5.1% of total construction output, and is projected to grow to $25.4 billion by 2029 - a compound annual growth rate of roughly 4.5%, according to industry data.
On the procurement side, the Trump administration issued two executive orders in April 2025 requiring structural changes to the Federal Acquisition Regulation (FAR), representing one of the largest procurement overhauls in decades. The resulting Revolutionary FAR Overhaul, targeting completion in fiscal year 2026, emphasizes commercial solutions, best-value acquisitions, and faster award cycles. According to regulatory guidance, over 500 FAR provisions may be eliminated or retired, with a third of non-essential content under review.
Federal agencies including the GSA, the Department of Defense, and the U.S. Army Corps of Engineers already specify BIM formats to ensure interoperability and facility management compatibility on construction projects. The DoD and GSA frequently require IFC (Industry Foundation Classes) Coordination View or IFC 4 for interoperability, while COBie (Construction Operations Building Information Exchange) is required for asset data, equipment details, and operations and maintenance information.
Details
The most consequential near-term development for the offsite sector is the pending CFOC/ICC 1220 Standard. The International Code Council and the Center for Offsite Construction (CfOC) at the New York Institute of Technology announced a collaboration in April 2025 to develop the "CFOC/ICC 1220 Standard on Configurations and Connections for Off-Site Construction," with publication expected by May 31, 2026. The standard will address module-to-module and building-to-module connections for essential building systems - including structural, plumbing, electrical, mechanical, and fire protection - as well as the standardization of dimensions for modular components covering componentized, panelized, and modularized elements.
The CfOC has described the initiative as modeled after successful cross-industry interoperability precedents, analogous to USB standards in electronics. Upon ANSI approval, the standard will be freely available on the ICC's Digital Codes platform.
"This partnership will support the growth of industrialized construction methods and ensure that off-site construction systems meet the highest standards of performance and interoperability," said Jason Van Nest, director of the CfOC at New York Tech, in a statement accompanying the announcement.
For general contractors operating in public-sector markets, the simultaneous arrival of FAR reform and the CFOC/ICC 1220 standard creates both opportunity and compliance pressure. Current federal directives favor modular contracting to increase agility, and the FAR overhaul expressly targets non-statutory compliance burdens, directing agencies to remove provisions not essential to sound procurement while placing more onus on contractors to justify cost proposals and maintain defensible pricing.
On the productivity side, measurable schedule gains support the case for offsite methods in public works. According to the Dodge Construction Network's Prefabrication and Modular Construction SmartMarket Report, builders using offsite methods routinely achieve 20-50% reductions in construction schedules. Factory workers in modular facilities achieve productivity rates 20-50% higher than equivalent site-based labor, operating from fixed workstations in controlled indoor environments.
The U.S. offsite construction industry has yet to organize open-source, widely adopted standardized interfaces between its products - a gap that currently locks the sector into engineer-to-order inefficiencies, increased costs, and limited scalability, according to the CfOC.
Outlook
The Modular Building Institute's government affairs team is scheduled to brief the industry at the 2026 World of Modular conference on policy issues including prevailing wage rules for offsite fabrication, state adoption of modular construction for affordable housing, and the implications of federal action on manufactured housing. The CFOC/ICC 1220 standard's consensus committee - seated in late 2025 following an ANSI-compliant selection process - is expected to complete its first draft scope before the standard's planned May 2026 release. Contractors seeking federal work are advised to map their capabilities to specific NAICS codes reflecting modular deliverables, as federal agencies in 2026 frequently use automated filters that prioritize entities with a performance history in narrow, specific NAICS categories.
