Outreach Event: Engineering Design Services Phased and On-Call Contracts

Seattle Public Utilities is conducting a presolicitation outreach effort for upcoming engineering design services, transitioning from traditional on-call contracts to phased contracts to increase inclusivity and WMBE participation. The agency is seeking expertise in civil, mechanical, electrical, structural, geotechnical, and hydraulic modeling, among other specialties. Planned projects for 2026 and 2027 include the Duwamish Stormwater Pump Station, watermain and pipe rehabilitation, creek and floodplain design, and the Cascades Dam Rehabilitation. Estimated contract values range from approximately 6 million dollars to 30 million dollars per contract, with some long-term engagements extending up to 10 years. All City of Seattle consultant contracts exceeding 420,000 dollars require a WMBE Inclusion Plan, and firms must self-certify via the OpenGov Procurement Portal to qualify. The outreach process is designed to facilitate networking between prime and sub-contractors and to inform firms of approximately eight upcoming solicitations. While this specific posting is for an outreach event and not a request for proposals, it establishes the framework for future bidding, including requirements for monthly B2G reporting and adherence to city insurance standards.
