Using a roster is an alternative contracting process that most Washington public agencies can follow as a way to more efficiently fulfill small to medium sized contracting needs. Although using a roster process can expedite projects, there are still contracting procedural requirements that should be followed based on the type of roster and in accordance with internal agency policies.

Roster Authorization

Washington city and county governments are authorized to use a roster process, but not all special purpose districts are authorized.

Statutory Guidelines

  • Small Public Works Roster
    The Small Works Roster (SWR) may be used for projects under $300,000.00, including construction, building, renovation, remodeling, alteration, repair, or improvement of real property as referenced by RCW 39.04.155. All agencies with federal public works projects (not purchasing) must bid their projects if the cost is $150,000 or greater. Please note that federal standards may be more stringent than state statute (see Uniform Guidance 2 CFR 200) in some circumstances. Careful review of federal thresholds is strongly recommended for all projects.
