RFQ - 2027 Geotechnical Engineering Services

Lewis County Public Works is requesting Statements of Qualifications from geotechnical engineering consulting firms for on-call services throughout calendar year 2027, with proposals due November 5, 2026 at 2:00 PM and interviews scheduled for December 3, 2026.

The selected consultant must employ at least one Washington State licensed geotechnical engineer or licensed geologist. Lewis County intends to enter into a single Negotiated Hourly Consultant Agreement with one firm and issue task orders on an as-needed basis for multiple project types, including Rural Arterial Program (RAP) funded projects, FEMA funded projects, U.S. Department of Housing and Urban Development (HUD) funded projects, and Lewis County Transportation Improvement Program (TIP) projects. Each task order requires written authorization from Lewis County prior to work execution.

The scope encompasses site investigation and characterization, drilling, soil and rock sampling, geotechnical laboratory testing, slope stability analysis, foundation design, pavement investigations, landslide evaluations, construction observation, and emergency response services related to bridges, culverts, roads, trails, and other public works infrastructure. All work must comply with federal provisions, WSDOT, AASHTO, and Lewis County requirements.

The anticipated maximum contract value is $350,000 for the one-year term (January 1–December 31, 2027), with the amount subject to increase at Lewis County's sole discretion. The contract includes a mutual option to extend for an additional year.

Statements of Qualifications are limited to 15 pages and must include a one-page cover letter, demonstrated competence in geotechnical services, relevant experience with similar projects, an organizational chart with key personnel resumes, and project references. Evaluation criteria weight demonstrated availability and response time at 25 percent, available resources including drilling and laboratory equipment at 20 percent, competence and qualifications at 20 percent, and past experience with similar work, performance evaluations by government agencies, demonstrated ability to meet schedules, and proposed sub-consultants at 10, 10, 10, and 5 percent respectively. Short-listed firms will be notified November 19, 2026. Questions are due October 30, 2026 at 2:00 PM.
