Request for Information Downtown Redmond Link Extension (DRLE) Project To: Prospective Proposers From: Sound Transit Procurement & Contracts Division Date: January 16, 2018 Downtown Redmond Link Extension (DRLE) Project Sound Transit is requesting industry comments on its upcoming Downtown Redmond Link Extension (DRLE) Project, located in the City of Redmond in King County, Washington. Sound Transit anticipates utilizing the Design-Build delivery method for this Project. The Project will extend light rail for 3.4 miles from the Redmond Technology Center Station at NE 40th Street to Downtown Redmond. Project elements include a double-track guideway (elevated and at-grade), one elevated station, one at-grade station, structured and surface parking, civil and site work, roadway work, and bus transit facilities. Sound Transit is providing prospective proposers interested in the Project an opportunity to review the Project and provide feedback. At this time, Sound Transit is only requesting comments and will not provide any responses. Sound Transit requests that prospective Proposers submit comments by January 26, 2018. Please submit all comments to: Petra Payne Sr. Design & Construction Contracts Specialist Sound Transit 401 S. Jackson Street Seattle, WA 98104-2826 Email: [email protected] The information contained in this document is subject to change prior to the issuance of the Request for Qualifications. Downtown Redmond Link Extension RFI P a g e | 1 January 2018 Request for Information Downtown Redmond Link Extension (DRLE) Project Sound Transit is particularly seeking the industry’s perspective and feedback related to: Whether there are concerns with performing the Design-Build work for the DRLE Project near and under SR-520 corridor, rebuilding the on and off ramps at the SR-202/SR-520 interchange, and working in downtown? Potential locations for staging areas are identified in the attached drawings. Of these potentials, please identify which locations would be beneficial for the Project. What are some concerns if the footprint of the staging area is limited? In general, the Project Requirements for the Design-Build contract will have prescriptive requirements for items such as the guideway footprint, right-of- way, roadway typical sections, and transit system components. Where do you believe Sound Transit can gain the highest value from having performance- based requirements (versus prescriptive requirements) on this Project? Based on the initial information on the scope and complexity of the Project and the Design-Build delivery method, what are the potential major challenges for the DRLE Project? Additional questions and comments with respect to this Project; whether it is scope, contract delivery method (Design-Build), or procurement process – are welcome. Sound Transit Project Delivery Team Structure Design-Build construction projects at Sound Transit are delivered by a dedicated project team consisting of construction managers, engineers, architects, operations and maintenance personnel, and project control specialists, as well as individuals representing procurement and contracts, stakeholders, right-of-way acquisition, government relations, permitting, environmental, planning, community outreach and related disciplines throughout the duration of the project. Downtown Redmond Link Extension RFI P a g e | 2 January 2018 Request for Information Downtown Redmond Link Extension (DRLE) Project In addition, Sound Transit anticipates engaging the services of a Design-Build Project Management (DBPM) consultant to augment the Sound Transit project team during design and construction. The DBPM will participate in contract administration, design oversight and review, construction oversight, quality verification, and safety and environmental compliance oversight. Key Stakeholders Since the initiation of the DRLE planning phase in 2011, Sound Transit has forged strong working relationships with the “Authorities Having Jurisdiction (AHJ)” including City of Redmond, King County and WSDOT. Stakeholder outreach is ongoing with major public and private utility operators. DRLE Design Build Project Description Project Scope Voters approved funding for preliminary engineering for the Redmond Link Extension in the 2008 Sound Transit 2 (ST2) ballot measure. Due to the recession in 2007-2009 resulting in a large reduction in tax revenues, the ST2 program was realigned to maintain affordability. Sound Transit Board suspended some projects and project phases until funding could be identified. Preliminary Engineering for the DRLE Project resumed in 2016 after funding approval for Sound Transit 3 (ST3). This Project is now part of the voter-approved ST3 plan to add 50 more miles of light rail throughout the region. The Project consists of Light Rail Transit (LRT) civil and systems works from the Redmond Technology Center at NE 40th Street to Downtown Redmond. The alignment for the revised preferred alternative starts at the Redmond Technology Center station and runs parallel to the east side of SR-520 as it travels north to the SR-520/West Lake Sammamish Parkway NE interchange. The profile in this section is at-grade and retained cut with cut and cover sections under 40th, 51st and 60th Streets. The alignment transitions to elevated guideway on a new bridge, crossing the Sammamish River. The elevated alignment then transitions to an at- grade section along SR-520 as it crosses the North edge of Marymoor Park to the SE Redmond Station. From the SE Redmond Station, the alignment crosses at-grade underneath SR-520 before rising to cross over Bear Creek. The SR-202/SR-520 interchange off-ramp and on-ramp are reconstructed over the at-grade guideway. Downtown Redmond Link Extension RFI P a g e | 3 January 2018 Request for Information Downtown Redmond Link Extension (DRLE) Project The alignment stays elevated from Bear Creek to downtown Redmond within the south edge of the Redmond Central Connector easement. An elevated Downtown Redmond station spans 166th Avenue NE, and the light rail line terminates east of 164th Avenue NE with tail tracks (Figure1). Figure 1 – DRLE Revised Preferred Alternative Downtown Redmond Link Extension RFI P a g e | 4 January 2018 Request for Information Downtown Redmond Link Extension (DRLE) Project The DRLE Project, subject to final Sound Transit Board Action, consists of the following major elements: Approximately 3.4 miles of turnkey double-track elevated, retained cut and at- grade light rail guideway including systems. Two stations: - An at-grade station in SE Redmond in the vicinity of Marymoor Park. - An elevated station in Downtown Redmond at 166th Avenue NE. Bus transit, park-and-ride, and parking facilities development. Reconstruction of freeway ramps at SR-202/SR-520 interchange to allow at- grade light rail guideway at this location. Parking of about 1,400 stalls – a combination of structured and surface parking located at the SE Redmond Station. Cut and cover crossings including retaining walls, utility relocation and decking. Facility accommodations and systems elements consisting of conduits and duct banks, traction power substations, signal houses, overhead catenary system, signal and communications systems. Roadway work, sidewalk construction and landscaping associated with light rail facilities. Utility work including both public and private re-locations.

A key element at the station involves providing 1,400 parking spaces split between a parking garage for 1,100 stalls to the east of the SE Redmond Station platform with frontage on NE 70th Street, and 300 surface parking spaces, located to the west of the station platform. Bus transit is integrated into the ground floor/street level of the parking garage. The geometry of the station, guideway and traffic impacts necessitates localized changes in alignment with NE 70th Street and improvements to the street section. There could be potential trail connections with the East Lake Sammamish Trail to the SE Redmond Station. Additional considerations for the station are bus facilities, storm water and utility approaches and strategy.

The station location facilitates integration of bus and rail. Key considerations for the station are tail track configuration, bus facilities, utilities strategy and Redmond Central Connector access, and restoration work at the 76th Street and the Redmond Central Connector.
