ODOT Subcontractor Payment and Oversight Processes: An Overview of Audit Findings

Prompt Payment Requirements

Federal regulations (49 CFR 26.29) require recipients of federal funds to ensure prime contractors pay subcontractors within 30 days of receiving payment. Furthermore, Oregon state law (ORS 279C.580(3)(a)) sets a stricter standard for public improvement projects, mandating that prime contractors pay subcontractors within 10 days of receiving funds from the agency. Failure to carry out these requirements constitutes a material breach of contract.

Audit Findings on Payment Timeliness

An internal audit of the Oregon Department of Transportation (ODOT) evaluated subcontractor payments to determine compliance with these regulations. The audit found a noncompliance rate of 25% based on an allowed 15-day window (the 10-day state requirement plus 5 days for administrative processing). Among the payments that were not made timely, the wait times ranged between 16 and 89 days.

Federal Review of Monitoring Processes

In September 2021, the Federal Highway Administration (FHWA) reviewed ODOT's processes and determined that the agency's monitoring and enforcement of prompt payments were non-compliant with federal regulations. The FHWA specifically noted that ODOT relied on a complaint-driven system, which federal guidelines do not permit as the sole mechanism for oversight. Following up on this, internal auditors found that ODOT had not taken timely steps to resolve the noncompliance and had not updated its Disadvantaged Business Enterprise (DBE) Program Plan since 2018 to address the weaknesses identified by the FHWA.

Identified Procedural and Communication Gaps

The audit identified several administrative gaps that affect the reporting and enforcement of prompt payments:

• Lack of Documented Procedures: There are no formal procedures detailing how prompt pay is to be monitored. For example, auditors interviewed nine Resident Engineers overseeing projects with late payments and found that none of these late payments had resulted in a conversation with the prime contractor prior to the audit inquiry.
• Training Deficiencies: While ODOT offers labor and compliance training that is attended by internal staff and external contractors, the training curriculum does not describe how prompt payment monitoring is to be conducted, nor does it outline the consequences for noncompliance.
• Outdated Reporting Instructions: When ODOT updated its processes to allow prime contractors to submit multiple partial payments to subcontractors in a single month, it failed to update the instructions for the Paid Summary Reports (PSRs). Consequently, contractors did not receive updated guidance on how to report these split payments.

Summary

To align with federal and state prompt payment laws, internal audits recommend that ODOT establish clear monitoring policies and compliance metrics. This includes updating the instructions on payment reporting forms, defining specific oversight roles for agency staff, and incorporating explicit prompt payment requirements into mandatory training for both contractors and invoice reviewers.
