Kiewit Infrastructure West Co (KIWC) has been selected as the General Contractor/Construction Manager (GC/CM) for the Elliott West Wet Weather Treatment Station (EWWTS) project performed for King County Wastewater Treatment Division (WTD).
The EWWTS project includes the procurement and installment of an Ultraviolet (UV) Disinfection System to replace the existing chlorine disinfection system at the Elliott West Wet Weather Treatment Plant, among a number of other improvements. The preconstruction phase of the project commenced in July 2024 and is planned to end in Q3 of 2027. The overall project also includes: Upgrades to the screening facility, installation of new pumps, added ballasted sedimentation technology for solids removal, miscellaneous electrical upgrades, and modifications to the operation of the Mercer Street tunnel.
The GC/CM intends to select a vendor/subcontractor to procure the new, complete UV Disinfection System utilizing the alternative selection process in accordance with the provisions in RCW 39.10.385. The reason for utilizing this alternative selection include, but are not limited to, the following:
- Early procurement allows KIWC the ability to mitigate risk from supply chain issues and specialized components that must be identified to complete design
- Improvement of cost and schedule certainty by allowing the design to proceed without multiple iterations for different design components
- Procurement of materials are based on best fit and function rather than solely basing the selection on the lowest priced responsive bid received
- Selected vendor will provide valuable input throughout the design phases of the Project. Vendor will be able to work with design team and communicate important information through each iteration of the overall design.
