Seismic Valve Improvements

The City of Tualatin is soliciting professional engineering services for the Seismic Valve Improvements Capital Project, aimed at installing seismic valves on six water storage tanks to automatically isolate inlets and outlets during an earthquake. Proposals must be submitted via the BidLocker portal by 2:00 p.m. local time on August 17, 2026, and must strictly adhere to the format and content requirements outlined in the Request for Proposals. Submission methods like email or physical delivery are not accepted, and late proposals will be disqualified. The project involves final design and construction documentation for seismic valves, restrained piping, vaults, and SCADA integration, based on the City’s Preliminary Engineering/Basis of Design Report. Work includes existing condition verification, seismic evaluations, permitting, construction oversight, outage planning, and coordination with state agencies such as the Oregon Water Resources Department and Oregon Health Authority. The estimated contract value ranges from $1,182,875 to $1,741,325, depending on the selection of cost options across the reservoirs, with project completion required no later than June 30, 2027. The contract is governed by Oregon’s Public Contracting Code and Tualatin’s own procurement rules, not federal FAR clauses, and includes custom contractual sections covering scope, standard of care, indemnification, and compliance. Evaluation of proposals will be based on a trade-off process emphasizing technical merit and best value, not lowest price. The highest weighted factor is Project Understanding and Approach at 35 points, followed by Project Team Experience at 25 points and Project Samples at 25 points, with pricing accounting for 15 points. Submission of an Introductory Letter is mandatory and pass/fail; failure to submit results in disqualification. Proposers must demonstrate compliance with Oregon tax laws, maintain a valid City business license, register with the Oregon Secretary of State, and agree to non-discrimination policies that affirmatively encourage minority- and women-owned business participation. Insurance requirements include $2 million professional liability, $2 million general liability, and $1 million automobile liability, all naming the City as an additional insured. The Consultant must retain all records for six years after final payment and promptly notify the City of any grant compliance issues. All deliverables, including design drawings, reports, and record documents, must align with the City’s Basis of Design and conform to the Standard of Care for Oregon engineering practice. Electronic submissions must follow strict page limits—
