Issue

ISSUE

 

Per the Full Funding Grant Agreement (FFGA) for the Westside Purple Line Extension (WPLE) Section 1, Metro committed to make appropriate infrastructure modifications to allow the Red and Purple Lines to operate at reduced headways. These requirements were carried forward as like provisions under the terms of the FFGA for WPLE Section 2. The current design contract for the Division 20 Portal Widening Turnback Project as approved in a March 2017 Board Action included the widening of the existing tunnel portal and construction of a turnback facility. 

As preliminary engineering has progressed, modeling for achievement of 4-minute headways and modifications to the turnback layout have produced significantly improved turnback and additional storage capacity for the Red and Purple Line, necessitated by the increased capacity needs generated by completion of WPLE Section 3 in addition to Sections 1 and 2, as well as system wide transit operations.  In addition to improved track and storage facility layout, these proposed changes, identified in the preliminary engineering phase, include improved access to a future Arts District station at 6th Street and accommodating potential future alignments for Link Union Station and High Speed Rail.    

 

 

Background

BACKGROUND

 

On March 23, 2017, the Metro Board of Directors certified the Final Initial Study/Mitigated Negative Declaration (IS/MND) and approved the award of a design contract for the Division 20 Portal Widening Turnback Project.  The project is required to support four-minute service on the Westside Purple Line Extension (WPLE) per the project’s Full Funding Grant Agreement which requires the ability to support two-minute headways east of the Wilshire Vermont Station where the Red and Purple Lines share tracks. The scope of the project was to construct a turnback facility on the west side of the Red and Purple Line yard (Division 20) with the turnback facility terminating east of the One Santa Fe residence and within Metro property located between First Street and Third Street.  It also included widening the existing tunnel portal to accommodate the additional tracks.  The adopted Initial Study/Mitigated Negative Declaration (IS/MND) environmental analysis prepared for the project included full acquisition of the Tow Yard property.

On April 27, 2017, the Board received an update (File #2017-0130) on Metro’s long-term needs at Division 20 in the Downtown Los Angeles Arts District and the accommodations necessary for a potential future Arts District passenger rail station  (the majority of public comments on the certified IS/MND showed a strong preference for a station to be located in the Arts District vicinity of 6th Street).  The report also addressed increased storage capacity for Metro’s growing rail fleet including accommodations for storage of WPLE trains in the Red Line Yard.  With the passage of Measure M, Sections 2 and 3 of WPLE are slated to be delivered as early as FY24 and no later than 2026, accelerating the need for expanded storage capacity in the yard. 

Subsequently, the Division 20 Portal Widening Turnback Project has been revised to include storage tracks for WPLE as well as a modified turnback facility that not only meets operational requirements and flexibility, but minimizes significant future infrastructure modifications if a future project for a 6th Street Station is approved and funded.  The combination of portal widening and turnback tracks/signaling to support a two minute headway, additional storage tracks and accommodation for a potential, future station at 6th St - all within a constrained footprint of an active rail maintenance and storage site - have significantly increased the size and complexity of this project.

With this more holistic approach, staff has identified additional real estate impacts and other critical work including: civil and trackwork improvements, structural modifications to the First Street Bridge, demolition, and installation of a new power substation.  The project is also coordinating with the Emergency Security Operations Center (ESOC), the proposed Link Union Station, and High Speed Rail projects, and incorporating needed “not to preclude” design elements of these projects to minimize potential conflicts during the turnback project’s construction and reduce throw away work, including the addition of a ventilation facility.  See Attachment D.

Due to these changes in scope, an Environmental Impact Report (EIR) has been initiated for the modified project with the Notice of Preparation filed in October 2017 and the required public scoping meetings held over the past two months in October and November of 2017.

Staff is recommending approval of this Board action  to provide sufficient contract funding for Metro’s Design Consultant, TYLIN, to address all of the needed modifications and complete services through final design, bid support services, and design services during construction.  In addition to the increased design costs which are directly related to the changes described in this report, including updated track layout, increased power capacity, vehicle storage and “not to preclude” improvements for coordination with Link US and High Speed Rail, staff is recommending an increase of $1,000,000 in contract modification authority to address any further changes that may be required for final design of the project.  Overall schedule of the project will remain unchanged. TYLIN will continue to meet or exceed the Disadvantaged Business Enterprise goal of 27%.

DETERMINATION OF SAFETY IMPACT

 

Approval of this item will have no impact on safety. 

Financial_Impact

FINANCIAL IMPACT

 

This project is funded on a fiscal year basis under Project number 865519 Division 20 Portal Widening Turnback Facility, cost center 8510, under various accounts including Professional/Technical Services and ROW acquisitions. The project is authorized to expend up to a cumulative amount of $76.9M through the FY18 period.  However an FY18 funding amendment is required to allow for recommendations A, B and C.  Upon approval of the recommendations, the FY18 budget authority will be increased by $25.0M, to $101.9M.  This is a multi-year project requiring expenditure authorizations in fiscal year increments until a Board Authorized Life of Project Budget is adopted.  It is the responsibility of the Project Manager and Chief Program Management Officer to budget for this project in future fiscal years. 

 

 Impact to Budget

 

Through FY18, the sources of funds for the recommended actions are Measure R 35% and Cap & Trade Transit and Intercity Rail Capital Program (TIRCP).  Due to the underground nature of the project work scope, Proposition A or Proposition C funds were not considered and are not included in this authorization request.  There is no impact to Operations eligible funding.  No other funds were considered.

 

Alternatives_Considered

ALTERNATIVES CONSIDERED

 

The Board could decide not to approve the recommended Contract Modification.  This course would delay completion of final design and is not recommended due to potential impacts to construction and thereby jeopardizing completion of the project and requirements of the FFGA for WPLE Section 1. 

 

Next_Steps

NEXT STEPS

 

After Board approval and execution of the Contract Modification, staff will direct the consultant to continue providing final design engineering services and design support services during construction of the Division 20 Portal Widening Turnback Project.  Staff will proceed with purchase agreement with the property owner. 

 

An overall LOP has not been established for this project pending completion of design.  However, these changes to the original scope will generate an increase in the original cost estimates.  Staff expects to return to the Board for authorization and funding to acquire additional properties impacted by the project and award of contracts for:

 

                     Construction Management Support Services

                     Traction Power Sub Station

                     Early Demolition

                     Construction

 

In addition staff will request Board certification of the Environmental Impact Report.
