Safe Harbor Indirect Cost Rate

Firms new to the Indirect Cost Rate (IDR) process may qualify for the Safe Harbor program.

The federal Safe Harbor program helps remove financial barriers that may otherwise prevent new, small, and disadvantaged architectural and engineering (A&E) consulting firms from entering the engineering services market federally funded under contracts with state Departments of Transportation.

The Safe Harbor Indirect Cost Rate option is 110% of direct labor with a field rate, when applicable, of 80% of direct labor. Use of Safe Harbor rate is optional to the firm, and will not be subject to audit. Although the Safe Harbor rate is not auditable, the WSDOT or local agency agreement is still subject to audit based on the terms and conditions of the respective agreement.

Who qualifies for the Safe Harbor rate

  • New and/or small A/E firms that have not had a Federal Acquisition Regulation (FAR) compliant indirect cost rate in the past
  • Firms that are new to working with the government

When the Safe Harbor rate may apply

  • Primes and sub-consultants, for use on WSDOT and local agency consulting agreements
  • The Safe Harbor rate may be applied to new agreements and new task orders
  • The WSDOT Internal Audit Office will be responsible for determining whether a firm is eligible to use the safe harbor rate

Steps to join the Safe Harbor program

Safe Harbor document checklist (PDF 355KB)

  • Complete the Timekeeping Training and provide the training certificate to WSDOT Audit.
  • Read the Pathway to Compliance (DOCX 30KB) to ensure your firm can eventually meet the requirements to provide a FAR-compliant Indirect Cost Rate. As part of the Pathway to Compliance, firms entering the Safe Harbor Program agree to implement an accounting system capable of accumulating and tracking direct/indirect labor and other costs by contract, segregating indirect costs, and removing unallowable costs. We have also developed a Safe Harbor program timeline (PDF 492KB) that outlines the typical milestones a firm may encounter.

Slow down – lives are on the line. 

In 2023, speeding continued to be a top reason for work zone crashes.

Even one life lost is too many.

Fatal work zone crashes doubled in 2023 - Washington had 10 fatal work zone crashes on state roads.

It's in EVERYONE’S best interest.

95% of people hurt in work zones are drivers, their passengers or passing pedestrians, not just our road crews.
