The Modular Building Institute says it has filed a federal lawsuit challenging Oregon's expansion of prevailing-wage requirements to specified offsite work for public projects. The dispute matters to modular manufacturers and international suppliers because labour obligations, payroll records and bid pricing may depend on where work is performed and how the public-works scope is defined.

What Has Happened

In its 20 August announcement, MBI states that Oregon HB 2688 expands the definition of public works to include certain offsite custom fabrication, assembly and construction performed specifically for public projects. MBI also says the law may apply Oregon wage rates to qualifying offsite facilities outside the state.

The association's lawsuit and objections are its stated legal position, not a final court determination. The official Oregon Legislative Information System page for HB 2688 should be used to review the measure, amendments and legislative record.

Why This Matters to Modular Procurement

Factory location may affect bid assumptions

Modular packages can cross state or national boundaries before reaching the site. If wage rules apply to covered factory activities, labour pricing and payroll administration may need to be addressed before award. Buyers should not assume that an offsite location automatically removes public-works obligations.

Scope definitions need contract-level clarity

Engineering, standard manufacturing, project-specific fabrication, assembly and site installation may be treated differently. The Oregon Bureau of Labor and Industries provides prevailing-wage information, but project teams should obtain qualified legal advice on the specific solicitation and contract.

ZH-ENG Analysis

The immediate procurement issue is uncertainty, not a proven universal cost increase. Bidders may price risk differently while the law and litigation develop. Public owners and contractors can reduce avoidable disputes by defining covered work, reporting responsibilities and change mechanisms in the tender documents.

What Buyers, Contractors and Suppliers Should Watch

• Confirm whether the project is a covered public work and which offsite activities are included.
• Identify the governing wage determination and effective dates before pricing.
• Allocate certified-payroll, record-retention and audit responsibilities.
• Require disclosure of factory locations and planned subcontracting.
• Include a controlled process for legal or regulatory changes after bid submission.

This article is an industry procurement analysis and not legal advice. International teams considering modular supply into U.S. public projects should engage local counsel and contracting specialists. ZH-ENG's modular building solutions can be discussed once the project scope, delivery boundary and local compliance responsibilities are defined.
