City Council Public Works and Natural Resources Committee — August 10, 2026
This was a brief afternoon committee meeting chaired by Council Member Michael Lilliquist, with Council Members Lisa Anderson and Jace Cotton also serving on the committee. The meeting had a single substantive item.
Contract Award: Post Point Wastewater Treatment Plant Emission Control Upgrades (EU199)
The committee considered authorizing the mayor to contract with Walsh Construction Company II LLC to provide pre-construction and construction management services for air pollution control upgrades at the Post Point Wastewater Treatment Plant.
What the project does: The project will upgrade emissions control equipment on both of Post Point's sewage sludge incinerator units, transitioning the plant from a less restrictive federal air quality standard (40 CFR Part 60, Subpart E) to a more stringent one (Subpart LLLL). Staff noted the project is also tied to the city's existing settlement agreement with the Northwest Clean Air Agency. The city is approaching a cost threshold on Incinerator 1 that would legally trigger the upgrade requirement anyway; the city chose to include Incinerator 2 proactively as well.
Why the GCCM process: Rather than a traditional design-bid-build contract, the city used a General Contractor/Construction Manager (GCCM) delivery method, which was previously approved by the full council in March 2025. This approach brings the contractor into the design process early — helping plan how construction will occur without shutting down the treatment plant — and allows cost estimates to be refined collaboratively through 30%, 60%, and 90% design milestones. Walsh was selected through a multi-phase scoring process (written proposals plus interviews evaluating experience with emissions-type work and GCCM projects) and also submitted the lowest contractor's fee proposal among three bidders.
Costs: Pre-construction services are estimated at $900,000; construction is estimated at $40 million. The final binding "Maximum Anticipated Construction Cost" (MAC) will be negotiated in open-book format at the 90% design milestone, expected later in 2026 or early 2027. The project also includes an apprenticeship hour requirement.
Council discussion on cost oversight: Council Member Lilliquist pressed staff on what happens if costs come in significantly above the $40 million estimate and where the council's budgetary oversight ends. Staff explained that cost estimates will be refined at each design milestone, giving the city at least two decision points before the MAC is locked in. If costs exceed the budget, the executive branch (mayor) would evaluate whether to proceed or exercise an "off-ramp" — generally guided by a 25% cost threshold and what has been approved in the sewer budget. Staff acknowledged candidly that given regulatory obligations, available off-ramps are limited. Lilliquist clarified his intent: "I want us to reduce air pollution and I want this project to go forward. I don't want to have to use an off-ramp."
Council Member Anderson asked about the point-based scoring criteria, and staff explained that firms were evaluated on their approach to the project, team qualifications, and relevant experience in both emissions work and GCCM delivery — in addition to the contractor's fee markup.

What happened at this meeting
A contract award for the Post Point Wastewater Treatment Plant Emission Control Upgrades Project (EU199), Bid No. 2B-2026
Staff presented a contract award to Walsh Construction Company LLC for the Post Point Wastewater Treatment Plant Emissions Control Upgrades Project (EU 199), selected through a GCCM alternative delivery process for submitting the lowest fee proposal and receiving the highest combined score based on qualifications, experience with emissions projects, and project approach. In response to Council member Anderson's questions, staff clarified that proposals were evaluated on contractors' project approach, emissions work experience, and team interviews—criteria beyond lowest bid alone. The maximum anticipated construction cost will be developed in an open book format and refined through 30%, 60%, and 90% design phases, with a current Class 4 estimate of $40 million. When a committee member raised concerns about cost overruns, staff explained that the mayor would exercise available off-ramps if costs exceed approximately 25% over the budget estimate. Council unanimously approved authorizing the mayor to contract with Walsh Construction Company LLC for pre-construction and construction services to upgrade air pollution control equipment and help the facility comply with more restrictive federal emissions requirements.
