Project information for contractors

King County (“the County”) issued a Request for Information (RFI) from interested and qualified firms (“Respondents”) to provide Progressive Design-Build (PDB) Services for the M Street Trunk Rehabilitation Project (M Street) which includes the repair of 13,800 LF of severely deteriorated sewer trunk line (18, 24, 30, and 36-inch) and repair of 45 maintenance holes.

The purpose of this RFI was to receive industry and/or market information, insight, and knowledge regarding the project. No contracts will be awarded as a result of this RFI. All responses are considered non-binding and are intended solely to inform the County’s development of a Request for Qualifications (RFQ) and Request for Proposal (RFP) for the project.

Contact Meredith Redmon, Project Manager (meredith.redmon@kingcounty.gov; 206-477-5488), OR Trisha Roth, Contract Specialist (troth@kingcounty.gov; 206-263-1964)

PROJECT LOCATION: The M Street Trunk Rehabilitation project will be located entirely within the city limits of Auburn, Washington and comprises the northern portion of KCWTD’s M Street Trunk. The project will include repair of over 13,800 linear feet (LF) of severely deteriorated 18-inch, 24-inch, 30-inch, and 36-inch diameter reinforced concrete sewer pipe with over 100 lateral connections and rehabilitation of 45 precast maintenance holes (MH). This work will require sewer diversion pumping through temporary above-ground bypass piping and odor control at each discharge location.  

PROJECT BACKGROUND: Several key challenges have been identified on this project. Interagency coordination with the City of Auburn (City) and Auburn Municipal Airport will be required to develop and gain approval for a work sequence along the alignment; work sequencing will need to accommodate planned City roads projects, airport operations, and work hours and traffic disruption constraints in three school zones located along the alignment. The M Street Trunk alignment crosses three major roadways and numerous minor roadways and planning and accommodation will be needed to minimize impacts of above-ground diversion piping to road traffic, transit routes, and business and residential access, including potential shallow bury of temporary sewer diversion piping at selected road crossings. Additionally, lining work can only be performed during a dry weather work window from June 1st to September 30th when typical flows in the conveyance system are seasonally low.

GMP ESTIMATE: $36M

TARGET SCHEDULE: RFQ Advertisement May 2023

EQUITY AND SOCIAL JUSTICE GOALS:

Expand opportunities for Certified DBE, MBE and WBE firms throughout design and construction. Voluntary Utilization Goals  and Workforce Requirements will be established prior to issuance of the RFQ.

POTENTIAL FUNDING SOURCES: This project is funded by King County.

Request for Information

Eastside Interceptor Section 8 Project

Request for information

• PDB Services for Eastside Interceptor Section 8 Project (RFI Executive Summary)

Project information for contractors

King County (“the County”) issued a Request for Information (RFI) from interested and qualified firms (“Respondents”) to provide Progressive Design-Build (PDB) Services for the Eastside Interceptor Section 8 Project (ESI Section 8) which includes the rehabilitation of 4,800 LF of 90”-96” concrete sewer tunnel.

The purpose of this RFI was to receive industry and/or market information, insight, and knowledge regarding the project. No contracts will be awarded as a result of this RFI. All responses are considered non-binding and are intended solely to inform the County’s development of a Request for Qualifications (RFQ) and Request for Proposal (RFP) for the project.

Questions?

Contact Ann Fowler, Project Manager (afowler@kingcounty.gov; (206) 477-9115), OR Melissa Jordan, Contract Specialist (mejordan@kingcounty.gov; (206) 263-4005)

PROJECT LOCATION: The Eastside Interceptor (ESI) is one of the primary sewer conveyance systems within East King County. The system collects untreated wastewater flows from various collection points beginning in Kirkland, Washington, and carries the flows to the KCWTD South Treatment Plant located in Renton, Washington. The ESI is categorized into fourteen sections for operations and maintenance purposes. This Project is associated with ESI Section 8, which is composed of 5,658 linear feet of 90-inch to 96-inch concrete tunnel. ESI Section 8, also known as the Sunset Tunnel, is experiencing significant degradation due to age, pipe material, and hydrogen sulfide-related corrosion and needs to be repaired to prevent failure, overflow, or disruption of service. Recent CCTV footage shows that this tunnel has areas of reinforcing steel exposed due to pipe wall loss.

PROJECT BACKGROUND: The upstream 800-feet of the tunnel was previously lined in 1996 and 1998 with a fully adhered PVC lining system (Linabond). This Project will rehabilitate the remaining 4,800 feet of the existing tunnel from the Energy Dissipating Structure located at the intersection of I-90 and I-405 in Bellevue, Washington to the maintenance hole structure located at the intersection of Coal Creek Parkway SE, 119th Ave SE, and I-405. Rehabilitation is anticipated to include installation of a liner system and other associated repairs. Access to the tunnel is limited to structures at the north and south end of the tunnel alignment; there are no existing or planned intermediate access points. Additionally, lining work can only be performed during a dry weather work window from June 1st to September 30th when typical flows in the conveyance system are seasonally low.

To facilitate pipeline rehabilitation, sewage flows will need to be diverted using a temporary pump station and a temporary parallel above-ground sewer line. The temporary sewer diversion is anticipated to follow the King County Eastside Rail Corridor (ERC) and exit from the corridor near the I-405/Coal Creek Parkway intersection. At this location, the temporary sewer diversion pipe will need to cross I-405 and discharge into the maintenance hole on the east side of I-405. The ERC is currently an unencumbered and unused corridor. However, the use of the ERC for the bypass alignment is only available until the end of 2025, because King County Parks is expected to begin construction early 2026 to convert this segment to a recreational trail. Key project challenges include routing of diversion piping to and from the ERC (including a major WSDOT crossing), and coordination with a concurrent capital project and environmental permitting at the south end of the alignment.

GMP ESTIMATE: $45M

Purpose

King County Wastewater Treatment Division (WTD) is holding an Open House requesting industry comments on its upcoming GC/CM Services for WPTP Project, located in Seattle, WA. King County anticipates utilizing the General Contractor/Construction Manager (GCCM) delivery method and is seeking Project Review Committee Approval on 3/23/2023.

King County is providing prospective Proposers an opportunity to receive an overview of the project, and to provide King County with feedback. King County welcomes discussion during the meeting, and will follow up with a formal Request for Information (RFI) through the E-procurement system in the near future.

PROJECT LOCATION: West Point Treatment Plant, 1400 Discovery Park Boulevard, Seattle, WA 98199.

PROJECT BACKGROUND: The West Point Treatment Plant (WPTP) provides secondary treatment for approximately 700,000 residents and businesses in Seattle and northern King County. With many mechanical, electrical, and support systems at the WPTP reaching the end of useful life, King County will invest more than $800 million over the next 10 years to upgrade the WPTP. This project will deliver a portion of that work, including mechanical, electrical, and seismic upgrades and will coordinate with other active construction contracts at the Plant. Constraints includes performing work on an operating wastewater treatment facility which requires carefully planned and executed outages, close coordination with Operations and Maintenance staff, and sequencing of projects to minimize Plant disruption. In addition, space is limited for contractor staging and parking which may require off-site lay down and parking.

MACC ESTIMATE: $150,000,000 - $200,000,000

TARGET SCHEDULE: Request for Proposal release target is 2nd quarter, 2023 pending CPARB PRC approval.

EQUITY AND SOCIAL JUSTICE GOALS: ESJ goals will be set in the near future. King County’s Master Community Workforce Agreement (MCWA) will apply to this project.

POTENTIAL FUNDING SOURCES: This project is King County funded, and could include grant funding from WIFIA, SRF, and FEMA. Program is subject to biennial funding, we expect to be working with GCCM to develop future funding requests.
