RFQ - Sewer Master Plan

The City of Seaside, Oregon, Public Works Department is issuing a Request for Qualifications (RFQ) to solicit consulting engineering firms for developing a comprehensive Sewer Master Plan. This procurement seeks a detailed 20-year strategic plan for the city's wastewater treatment system, which currently includes an activated sludge treatment plant with a 6.75 million gallons per day capacity, 25 lift stations, and approximately 75 miles of collection lines. The project requires developing capital improvement recommendations across near-term (0-5 years), mid-term (6-10 years), and long-term (11-20 years) horizons, with specific deliverables including hydraulic modeling, flow projections, biosolids management plan updates, infiltration and inflow studies, and ensuring regulatory compliance with NPDES permit requirements. Proposals will be evaluated using a merit-based scoring system with 40 points for demonstrated sewer master plan experience, 40 points for qualifications and expertise, and 20 points for unique services offered. The procurement timeline includes a pre-proposal conference on December 8, 2025, at 10:00 AM at the Seaside Wastewater Treatment Plant, with questions due by December 10, 2025, at 4:00 PM, and proposal submissions required through the OregonBuys portal by December 29, 2025, at 4:00 PM Pacific Standard Time.

The RFQ contains specific restrictions on potential respondents, explicitly noting that Solidsdude Solutions LLC and Waterdude Solutions LLC are ineligible due to their prior knowledge of the city's wastewater system. Proposers must obtain a City of Seaside Business License and maintain commercial general liability insurance of at least $2,000,000 combined single limit, while also complying with Oregon Workers' Compensation requirements. All proposing firms must complete the free online Pay Equity Training before contract award. The City plans to rank up to four firms and negotiate with the top-ranked qualified firm, with the contract potentially running from 2025 through 2026 and possible extensions by written agreement. While no specific budget range is detailed in the documentation, the comprehensive nature of the master plan suggests a significant professional services contract. The anticipated contract award date is January 6, 2026, with final approval contingent upon City Council review and acceptance of the negotiated scope and pricing.
