City of
StationLift Upgrade
Alternatives Analysis and Preliminary Desigi
This scope of work (SOW) describes the services to be provided by Parametrix, Inc. (Parametria) for
the Lift Station 12 Upgrade Project for the City of Tukwila (City). The City seeks to upgrade Lift
Station 12 to improve reliability, provide renewed longevity, enhance operational efficiency, and
bring the station into compliance with current codes. The City tasked Parametrix to provide
alternatives on how to address these concerns.
List Station 12 was initially built in 1972 and serves Drainage Basins 4 and 8. Upgrades to the lift
station were completed between 2001 and 2003, including pump replacements and a new on-site
generator. According to the City's 2014 Comprehensive Sanitary Sewer Plan (Carollo 2014), the
average annual flow for List Station 12 is approximately 0.19 million gallons per day (MGD) and peak
day average flow is approximately 0.72 MGD. Peak instantaneous flows were estimated to reach
approximately 1.18 MGD with infiltration and inflow contributing to approximately 0.57 MGD.
As identified in the City's 2014 Comprehensive Sanitary Sewer Plan (Carollo 2014), it was
anticipated that the pumps and the lift station structure would reach their useful life by 2023. The
City has considered alternative options to serve Drainage Basin 4 and currently, the pumps at the
existing lift station have not been able to keep up with the variable flows due to wear.
On June 5, 2024, City staff and the Parametrix team conducted a site visit at Lift Station 12 to
discuss the project. Alternatives initially discussed at the site visit with City staff included upgrades to
the existing station, converting the station to a submersible pump station, or building a new wet well.
The Lift Station 12 Upgrade Project includes developing and evaluating potential upgrade
alternatives through collaborative workshops with City personnel, conducting an alternatives
analysis, and determining a preferred design alternative for improvements at the existing lift station.
Subsequently, a preliminary design submittal will be prepared, including 30% design plans, an
outline of technical specifications, and a construction cost estimate.
This SOW does not include the Final Design Phase, which will be determined during the Preliminary
Design Phase, encompassing final design plans, specifications, construction cost estimates, and
necessary permit applications. This SOW also does not include bid support or services during
construction, which will be provided under a separate task order.

Objective
Task 05 provides initiating the Preliminary Design Phase of the preferred alternative determined in
Task 04. This task includes an initial design meeting with City staff, preparation and submission of
the Preliminary Design (30%) Submittal, including plans, specification outline, and engineer's opinion
of construction cost, as well as a design review workshop with City staff.
Subtask 05.1 includes kicking off the preliminary design phase with City staff and ensuring
stakeholders are aligned with the identified preferred alternative in Task 04, project goals, design
requirements, and project expectations for producing the 30% Design Submittal for Lift Station 12
upgrades. This meeting will focus on reviewing and confirming project goals and requirements;
revisiting the project schedule, including milestones and deliverables; and addressing any initial
questions or concerns from stakeholders.
Subtask 05.2 includes developing preliminary design plans for the proposed upgrades to Lift
Station 12 based on the preferred alternative determined in Task 04, generating a proposed list of
Construction Specifications Institute (CSI) and Washington State Department of Transportation
(WSDOT) technical specifications for the project, and preparing a 30% engineer's opinion of
construction cost.
A preliminary Drawing Sheet List is included as Exhibit C.
Subtask 05.3 includes a Preliminary Design Review Meeting with City staff to review City comments
and feedback on the Preliminary Design Submittal.
Task 05 Assumptions
■ Budget assumes the Initial Design Meeting will be attended by up to four Parametrix staff
(two in-person and one virtually) for up to 1.0 hours each. Budget includes travel time to the
City of Tukwila Public Works Office/Conference Room from the Parametrix Puyallup office
and mileage.
■ Budget assumes up to 12 sheets will be developed as part of the Preliminary Design
Submittal, as listed in Exhibit C. Should the preferred alternative determined in Task 04
require more Preliminary Design Plans than assumed, an amendment may be required.
■ The preliminary cost estimate will be prepared to the AACE Class 3. Typical accuracy ranges
for AACE classes vary depending on the technological complexity of the project, appropriate
reference information, and the inclusion of an appropriate contingency determination.
