nts to optimize traffic flow though the station were identified. Specifically, the design team plans to install a new stair, relocate the south fare array, reverse a stair, and slab over abandoned stairs. Descriptions of these improvements follow: Construct a New Stair P-15 (between uptown IRT platform and uptown IND platform) The element of work will include the demolition of existing mezzanine slab, the re-framing of the mezzanine floor system and the construction of a new stair from the mezzanine to the platform level below. This new stair shall be a steel stringer stair with perforated metal risers and all structural modifications required for the installation. Relocate Fare Array and Token Booth (mezzanine level) The element of work will include the removal and relocation of the existing turnstile array (all existing elements) and Token Booth N06051 several column bays to the north. This relocation shall be performed in conjunction with the northerly relocation of platform to mezzanine stairs P-1 and P-3. All labor necessary for electrical and communication work for this relocation is included. Reverse and Relocate a Stair P-4 (between mezzanine and IND platform levels) This element of work will include the demolition of existing platform to mezzanine stair P-4 and the relocation, reversal and construction of a new stair P-4, located to the north of its existing location. All structural modifications to the existing station elements necessary for this construction are included. Any portion of the existing stairwell opening not required for the new stair construction shall be slabbed over. Remove and Slab over Abandoned Stairwells P-1, P-2, P-3 and P-5 (between mezzanine and platform levels) This element of work will include the removal of the above listed existing stair and the slabbing over of the remaining stairwell openings. Repairs at the platform level following the removal of the stairs shall be made as required to restore the concrete platform finish. All structural modifications to the existing station elements necessary for this construction are included. Providing ADA Access The current Columbus Circle Station configuration has no elevators between the mezzanine and platform levels. The design team's proposal includes 3 ADA elevators that would provide access for physically challenged and elderly ridership to all platforms and mezzanines within the station. These elevators and their related components will be designed to current NYCT guidelines and specifications. Related components consist of electrical, communication and plumbing work. Currently, the New York MTA estimates that 187,000 physically challenged or elderly persons enter the Columbus Circle subway station annually. This figure is conservatively low given that NYCT can only track those riders that have sought out and use a special transit card that permits tracking when they enter the system at Columbus Circle Station. This does not account for the large ridership that utilize the station for the intra-system transfers. Construct a 3-stop ADA Elevator (connect IND mezzanine level, downtown IND platform & downtown IRT platform) This element of work will include the installation of one 3 stop elevator and its related machine room, as well as all ancillary components required for the operation of the elevator. All structural work necessary to modify the existing station to accept this elevator and machine room as well as the above described general electrical, communication and plumbing work shall be included in this item. Construct two 2-stop ADA elevators (connect IND mezzanine level to uptown IND platform) This element of work will include the installation of two 2-stop elevators and its related machine rooms, as well as all ancillary components required for the operation of these elevators. All structural work necessary to modify the existing station to accept this elevator and machine room as well as the above described general electrical, communication and plumbing work are included in this item. These elevators and their related components will be design and installed in accordance with current NYCT specifications and guidelines.
The Sustainable Sites Technical Advisory Group (LEED subcommittee) has determined that while the data provided does "qualify the significance of this station" as an element of a larger system, it falls short in providing quantifiable data to support the NYCT projection of a 4% annual system increase in ridership due to the improvements at the Columbus Circle Station. Similarly, the language of this CIR (and the previous CIR 0307-IDc10-062102) leaves out specific information regarding the physical and aesthetic improvements that will be made to lower barriers to ridership; this information is critical to determining the applicability of these improvements to the project's LEED Application. The USGBC encourages the applicant project to outline the specific improvements that have been made to he Columbus Circle Station that have lowered barriers to ridership, and to demonstrate (through peer-reviewed studies of such improvements in other mass transit stations or through ridership counts of the applicant building's staff and visitors) that these improvements have definitely affected the transportation habits of the applicant building's occupants. The applicant would also strengthen its case by summarizing the location of other ADA compliant stations in the area. Furthermore, the USGBC encourages the project to apply for an Innovation Credit, instead of equivalency for SS Alternative Transportation credits.
