Programmatic Services for Facility Programs: WTD is in the process of establishing capital delivery programs at several of our facilities. In continuing this effort, WTD has three (3) upcoming programmatic contracts to be procured to provide a wide variety of services to support the delivery of projects planned at these facilities: 

• Program Engineering services for the Brightwater Facility Program;
• Program Manager/Owner Advisor services for the West Point Treatment Plant Facility Program; and

Division Wide Offsite Level Controls & Communication Upgrade (Potential for GC/CM requires Alternative Delivery Committee (ADC) Review and Approval): The scope of this project is to bring all offsite facility wet well level controls and communications equipment into conformance with WTD Design Standards to improve safety, reliability, and operability. This program will replace obsolete level controls and communications equipment at Pump Stations (PS,) Regulator Stations (RS,) and Combined Sewer Overflow (CSO) facilities located throughout the service area. This project is anticipated to be implemented using the General Contractor/Construction Manager (GC/CM) collaborative delivery approach, pending CPARB-PRC approval. Total project construction budget is approximately $175.5M. 

South Plant RSP #3, Seismic Upgrades, and Division Channel Recoating (GC/CM): The scope of this project includes: STP Division Channel Recoating to recoat entire division channel just east of South Plant Influent Pump Station (IPS); Raw Sewage Pump #3 Replacement to replace the existing pump, variable frequency drive, motor control center, and associated piping; and IPS Seismic Upgrades to improve the seismic resiliency of the IPS by replacing the high roof and north wall, applying fiber reinforced polymer on several columns and walls, and architectural upgrades. This project is anticipated to be implemented using the General Contractor/Construction Manager (GC/CM) collaborative delivery approach, pending CPARB-PRC approval. Estimated cost is approximately $22.8M. 

West Duwamish Wet Weather Storage (ITB): The West Duwamish CSO Storage Tank is a 1.25 million gallon buried cast-in-place concrete combined sewage storage tank that includes drain pumps, tipping buckets, and associated mechanical piping. Deep soil mixing is located underneath the tank and adjacent conveyance structures. There is an aboveground facility building, including electrical and instrumentation and control (I&C) equipment, utility water system, standby generator, instrument air, restroom, and outdoor odor control area with carbon scrubber, odor control fans, and associated equipment, as well as conveyance piping and structures to route flows to and from the storage tank.

Projects highlighted will be those using the Alternative Public Works (GC/CM and PDB) process, as well as share opportunities on traditional DBB projects, Work Order contracts, and upcoming consulting contracts. To encourage early teaming arrangements, we hope interested firms attend.

A brief description of the projects WTD will be discussing at this Open House are:

South Interceptor Rehabilitation (PDB): This project will rehabilitate 1,623 linear feet of the South Interceptor and associated structures, located in the City of Renton. Rehabilitation of 445 linear feet (LF) of 72-inch and 1,185 LF of 90-inch diameter reinforced concrete pipe, rehabilitation of up to (7) maintenance holes, modifications to the junction structure at the South Interceptor and Eastside Interceptor (located at South Treatment Plant), which may be necessary to isolate flows during rehabilitation, and the design, installation and operation of sewer diversion pumping system (including all traffic control and restoration activities). Estimated contract cost is $36M.

Black Diamond Trunk Capacity Upgrade (GC/CM): This project will add conveyance capacity to accommodate population growth over time in a manner that meets King County’s commitments to provide conveyance services to the City of Black Diamond. The scope includes upsizing approximately 6 miles of 10-inch to 16-inch sewer pipe and associated appurtenances. This project is anticipated to be implemented using the General Contractor/Construction Manager (GC/CM) collaborative delivery approach. Total estimated contract cost is $75M.

Sammamish Plateau Diversion (GC/CM): This project will address regional conveyance system capacity needs by diverting flows out of the South Lake Sammamish Planning Area north. Diverting flows northward will alleviate capacity needs at several King County conveyance facilities. Estimated contract cost is $52.4M.

Mouth of Duwamish Combined Sewer Overflow (MDCSO) Wet Weather Facilities: The County's Wastewater Treatment Division (WTD) will programmatically deliver essential infrastructure to control wet weather sewer overflows in the Duwamish River. Driven by a consent decree with a 2034 deadline, the program scope involves building sewer diversion structures, influent and effluent conveyance, a new outfall, storage tank, system integration and SCADA, and treatment facilities that include an equalization basin, screens/compactor, pump station, solids removal, disinfection, solids storage, and odor control. With an emphasis on minimizing risks and avoiding delays, the project requires high engagement with interested parties and a coordinated management of multiple projects to deliver required benefits. The program is presently conducting an Alternatives Evaluation to identify the Best Apparent System Alternative (BASA). At this online open house, the County will provide an overview of work occurring to prepare for contracting delivery of MDCSO facilities including determining type of delivery and packaging of program elements.
