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.

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).

Request for Information Downtown Redmond Link Extension (DRLE) Project

The station platform is at grade, tucked close to the SR-520 right-of-way and the northeast boundary of the Marymoor Park. 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.

Estimated Design-Build Cost The estimated Design-Build cost for the Project is $500 to $600 million in 2017 dollars.

Planning and Environmental Approvals

The Downtown Redmond Link Extension was included as Segment E in the East Link Environmental Impact Statement (EIS) prepared pursuant to the National Environmental Policy Act (NEPA) and State Environmental Policy Act (SEPA) and published in July 2011. The Federal Transit Administration (FTA) and Federal Highway Administration issued Records of Decision in November 2011. Since then, conditions in the Project area have changed affecting how the segment can be constructed and operated. Sound Transit has updated the Project design, and the Sound Transit Board identified the revised preferred alternative in June 2017. Sound Transit and FTA are currently preparing a NEPA Re-evaluation and SEPA addendum to address changes in the Project. Sound Transit Board selection of the Project to be built is anticipated after completion of NEPA and SEPA review in the second quarter of 2018.

Sound Transit will compile a list of the environmental permit commitments and provide them to the Design-Build Contractor for incorporation into the Project.

Agreements and Permitting

Sound Transit will obtain lease agreements with WSDOT for the Temporary Construction Air Space Lease (TCAL) and permanent Air Space Lease (ASL) for work relating to Project improvements within SR-520 and SR-202 corridors.

Sound Transit is coordinating with City of Redmond and King County on the Project permitting and agreements. The coordination includes Design-Build process, station location workshops, urban design goals, and identification and resolution of various engineering and design issues. It is expected that final agreements with the City of Redmond and King County will be reached in 2018.

Permits to be obtained by the Design-Build Contractor include, but are not limited to, City’s Site Plan Entitlements (SPEs), Coordinated Civil Reviews (CCRs), Building Permits and their associated trade permits (mechanical, electrical, fire alarm, fire

sprinkler/standpipe, etc.), Demolition Permits, Clearing & Grading Permits, Right-of- Way Permits, and Temporary Noise Variance Permits; Department of Ecology’s Construction Stormwater General Permit; and WSDOT General Permits, for items not already covered under the TCAL or ASL.

Right-of-Way

Sound Transit is currently in the pre-acquisition phase of securing public and private fee acquisitions, permanent and temporary easements, and WSDOT TCALs and ASLs. A Right-of-Way acquisition schedule will be provided with the Design-Build RFP.

Major Utility Relocations

Utility relocations will be required for the cut and cover work at major road intersections along the alignment, stations, parking garage, as well as columns/deep foundations for the elevated guideway sections.

The “Utility Technical Memorandum” developed for the Project will identify all major utilities and will be included with the Design-Build RFP. The Design-Build Contractor will be responsible to coordinate and cooperate with the public and private utility owners, investigate utilities, relocate utilities, or protecting them in place. Utilities to be encountered on the Project include, but are not limited to, overhead and buried electrical lines, overhead and buried telecommunications (including fiber optic), overhead and buried TV cable, Intelligent Transportation Systems (ITS), signal interconnects, gas mains, water mains, sewer mains, utility vaults and hand holes, and service connections. Funding

In November 2016, voters approved the ST3 plan, which includes funds for the design and construction of the DRLE. Sound Transit intends to utilize a combination of FTA and Local Funds for this Project.

Project Risks and Potential Allocation

Sound Transit is in the process of updating and refining a Risk Matrix for the Project. Major identified risks will be presented during the Industry Outreach Event on January 31, 2018. The notification for the outreach event will be published via eBid.

Downtown Redmond Link Extension Page | 13 January 2018 RFI

Request for Information Downtown Redmond Link Extension (DRLE) Project

With respect to geotechnical information, Sound Transit intends to provide Design- Build proposers with a Geotechnical Data Report and a Geotechnical Baseline Report.

Based on available geologic mapping and subsurface drilling information contained in historical borehole records, the subsurface conditions along the western part of the alignment (approx. 1.7 miles) are anticipated to primarily consist of glacial till with some areas of mapped advance outwash. From the vicinity of Sammamish River to the end of the alignment, younger alluvium deposits including peats underlain by sands and gravels in varying density are anticipated.

The guideway section along Marymoor Park and the SE Redmond Station area will present geotechnical challenges due to the high probability of peat, high water table, and hydric soils.

Artifacts of archeological significance were observed during potholing and preliminary soil investigation north of Marymoor Park.

Historical borehole records used for this preliminary characterization of the subsurface along the DRLE corridor were obtained from the Washington State Department of Natural Resources (DNR), WSDOT, City of Redmond, Microsoft Corporation (Microsoft), and previous Golder Associates Inc. projects.
