(Parametrix) for the Lift Station 12 Upgrade Project for the City of Tukwila (City). The City seeks to upgrade Lift Station (LS) 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. Lift Station 12 was initially built in 1972 and serves Drainage Basins 4 and 8. Upgrades to the LS 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 Lift 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 LS 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 LS 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 LS 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. Amendment 2 to the Lift Station 12 Upgrade Project is to complete the design for the rehabilitation of LS 12, and to extend the scope of services from final design through bidding support and construction. Amendments to the initial contract are highlighted in yellow. The original scope of work included an alternatives analysis that resulted in the preliminary design, which included major structural changes to the LS. After the preliminary design was underway, the City requested to pursue a simpler rehabilitation of the LS in a meeting on October 30, 2025. A site City of Tukwila 216-2067-007 Lift Station 12 Upgrade 1 February 2026 Amendment 2 - Final Design, Bid Support, and Services During Construction 70MM71 MW visit was held on November 4, 2025, to discuss simpler rehabilitation options. The simplified rehab work includes the following: ■ Replacement of pumps with Vaughan chopper pumps and associated rigging/maintenance access. ■ Standardized controls/Human-Machine Interface (HMI)/Supervisory Control and Data Acquisition (SCADA) consistent with city stations (LS 2/8/10 basis). ■ National Fire Protection Association (NFPA) 820 ventilation and safety improvements in wet well and dry pit. ■ Practical bypass provisions (including a potential permanent discharge bypass connection) to streamline future work. ■ Exhibit A: Scope of Work (Amended). ■ Exhibit B: Limits of Survey. ■ Exhibit C: Preliminary Sheet List - Preliminary and Final Design (Amended). ■ Exhibit D: Rates and Fee Estimate (Amended). f_€.hihi+C: Dv.,Jnr++.,rlDvr,inr.+Cr.hr_,r-11f, Work Breakdown Summary: ■ Task 01 Project Management and Quality Control (Amended). ■ Task 02 Data Collection and Review (Amended). ■ Task 03 Develop Alternatives. ■ Task 04 Alternatives Analysis. ■ Task 05 Preliminary Design (Amended). ■ Task 06 Subconsultant Allocation. ■ Task 07 Management Reserve. ■ Task 08 Final Design. ■ Task 09 Bid Phase Services. ■ Task 10 Construction Phase Services.
