BACKGROUND In 2015, upgrades to the pumps, control panels, and force main were identified as a critical project. The project was approved for design in 2021 and construction took place in 2022. New pumps, valves, piping, and other appurtenances were installed. The upgrades have seen an improvement in reliability and a decrease in maintenance and upkeep needs. DISCUSSION The lift station 2 project was divided into two phases: the construction phase and the maintenance improvement phase. As construction has concluded and the maintenance and operations staff have had enough time to get used to the systems, it is time to start phase two. The maintenance access phase will view the safety of the City staff and the public as paramount. Improving access to the staff will make sure the structural integrity of the existing station remains intact, which will be the primary focus of this design contract and the subsequent construction project.

The existing lift station has three dry well submersible pumps located in a below grade concrete structure. The structure is split into two rooms — the control room above and the pump room below. Due to the fact that there is not sufficient access between the control room and the pump room, the City would like to modify the control room floor by expanding one existing hatch and installing one new access hatch above the pumps. The City would like to install a new monorail and trolley system to allow for lifting and removing the pumps. In addition to the structural modifications, it is understood that the City would like to repair a section of settled pavement surrounding an existing manhole adjacent to the lift station's driveway. Scope of Work PACE proposes to provide the following services based on our current understanding of the project: • Estimate code -required gravity and lateral loads based on the Washington State Building Code that takes effect March 15, 2024. • Design modifications to the existing floor slab to accommodate one new hatch and enlarging one existing hatch. • Determine impacts to the gravity load -carrying system of the floor slab gravity from the hatch modifications. • Determine impacts to the exterior walls due to the reduced diaphragm stiffness of the existing floor slab. • Verify the lift station is still heavy enough to counteract the effects of buoyancy. • Design one monorail beam that can remove a pump or components of the pump assembly. Secondary elements of the design will include: o Connections between the monorail and the roof slab or exterior wall. o Specification of a hoist. o Trolley stops. • Evaluate the configuration of the existing spiral staircase between the control room and the pump room and provide recommendation for revising the configuration if needed based on layout of the access hatches. • Evaluate and provide recommendations for the repair of pavement and manhole located in the southbound travel lane of Andover Park W. • Participate in one kickoff meeting and one mid -point review meeting. Kickoff meeting will be held in -person at the lift station. • Prepare structural calculations and summarize PACE's design in CAD -based drawings stamped by a Professional Engineer licensed in the State of Washington. 136 December 20, 2023 City of Tukwila LS#2 Structural Modifications —Scope Page 2 of 2 Assumptions The above scope of work is based on the following assumptions: • PACE will use their original design drawings and as-builts that illustrate the reinforcing steel. • The City will provide guidance on preferred hatches and hoists. • The as -built drawings substantially match the existing conditions. • The existing concrete is of sound condition and does not exhibit signs of deterioration. • The floor slab and exterior walls do not require strengthening to accommodate the new hatches. • The roof slab does not require strengthening to accommodate the monorail beam. • All meetings will be held virtually with the exception of the kickoff meeting to be held in - person at the lift station. Exclusions The following services are not included in this proposal: • All services not explicitly delineated in the Scope of Work. • Design of strengthening details to the slabs and walls. • Additional site visits beyond the kickoff meeting. • Review of existing equipment anchorage and utility supports. • Permitting and bidding assistance. • Services during construction. Project Costs The costs associated with the above described work are shown on the attached spreadsheet.
