NY starts procurement for Second Ave Subway Phase 2
More Procurement steps for Hudson Tunnel Project US – The Gateway Development Commission (GDC) issued Requests for Qualifications for two major packages of New York-New Jersey’s Hudson Tunnel Project – the EA1 contract, for the Hudson River Ground Stabilization (HRGS) project; and, the 1A contract, for the Palisades Tunnel project. The US$16bn project involves building the
new 2.4miles (3.9km) two-tube Gateway Tunnel under the Hudson River, between Newark, New Jersey, and New York City’s Penn Station, and refurbishing Amtrak’s existing North River rail tunnel, HRGS will fortify and stabilize the

US – New York’s Metropolitan Transportation Authority (MTA) has issued the first call for tenders for Phase 2 of the Second Avenue Subway extension. The project will extend the
subway to 125th Street in Harlem, improving transport links to East Harlem, which is one of the city’s most public transit-dependent neighborhoods. The first contract for Second
Avenue Subway Phase 2 incorporates lessons learned from Phase 1 and will involve critical utility relocation, laying the groundwork for advancing construction of three future stations and necessary system infrastructure. The contract is to be a design-
bid-build A+B contract, which incentivizes companies to compete on both cost and time. In 2022, MTA Construction and Development saved more than US$100m on A+B contract awards compared to estimates. Additional cost containment
initiatives in Second Avenue Subway Phase 2 include reuse of a tunnel section built in the 1970s from 110 Street to 120 Street along Second Avenue, early real estate acquisition, adoption of Best Value contract structures (like A+B contracts), reduction in back-of-house and ancillary space, and close co- ordination of contracts. It is expected the contract will

be awarded in the Q3/Q4 for initial work to begin by the end of the year. “As part of my administration’s
efforts to advance transit equity across New York State, the Second Avenue Subway project will expand critical public transportation service to East Harlem, creating more opportunity for residents,” said Governor Kathy Hochul. Revenue from congestion pricing
is to provide US$15bn in funding for critical projects in the MTA’s current capital program, which includes Second Avenue Subway Phase 2. The MTA is finalizing a funding agreement with the Federal Transit Administration (FTA) for the project and has been planning to secure federally required contingency for the project through a Capital Plan Amendment. Phase 2 will extend the Q Line by
approximately 2.4km. There will be two new stations at 106 Street and 116 Street on Second Ave, and a direct passenger connection with the existing 125 Street subway station on the Lexington Ave subway line. Phase 2 will also feature an
entrance at Park Avenue to allow transfers to the Metro-North Railroad 125 Street Station. The expansion will serve an
additional 100,000 passengers a day. Phase 1 of the project extended the Q Line from 63 Street to 96 Street and opened in 2017.
riverbed on the New York side of the Hudson River over a 366m section leading to the Manhattan Bulkhead. The work will improve conditions in which to bore the new tunnel through the eastern portion of the Hudson River section of the project. The project is expected to commence
in early 2024, ahead of the full tunnel construction. For the Palisades Tunnel, the RFQ
invited Statements of Qualifications for the design-bid-build procurement method in September. Palisades Tunnel is the first project in the full construction of the new Hudson Tunnel, is to use TBMs, and work is due to begin in the second half of 2024.
Vancouver metro advances CANADA – The second of two Herrenknecht TBMs excavating twin tunnels for Vancouver’s Broadway Subway Project has broken through at the future Broadway- City Hall Station. The breakthrough by TBM ‘Phyllis’
followed the arrival of TBM ‘Elsie’, in April. TBM ‘Phyllis’ was launched at the future
Great Northern Way-Emily Carr Station in November 2022 and excavated 1350m of tunnel and installed 884 rings. The two 6m-diameter machines are
undergoing planned maintenance following the recent breakthroughs before they are relaunched and continue boring. The breakthrough station, at 20m underground, will be the deepest station constructed on the subway project, the deeper alignment allowing the new tunnels to travel underneath the existing Canada Line. Broadway Subway Project is being
constructed by the Acciona-Ghella JV and is a 3.1miles (5km)-long extension of the Millennium Line, including 5km of tunnels and six underground stations. It is scheduled to open in 2026.
