King County Juanita Bay Pump Station

Design lead/project manager for environmental, civil, electrical, architectural and structural design of a 30 mgd, $20 million, multi-level pump station to replace an existing station that had reached its useful life and provide additional pumping capacity.

The design was made especially challenging by the station being on a small site located in a residential area. A phase 1 ESA was prepared. LEED/sustainable design and construction elements were incorporated into the project where feasible. Because of groundwater and other issues and considerations, a secant pile shoring system was incorporated into the structure’s design. The specifications included contractor and subcontractor qualifications as well as risk sharing (geotechnical baseline report). Some years after the construction of these facilities, while at another company, assisted HDR/King Co. prepare for, and defend a claim by the contractor on the pump station’s waterproofing system design. The waterproofing system design was validated and King Co. prevailed.
