Still on Track for December 2016?


Late in the day last Friday, news website DNAInfo New York reported that delays could push back the planned opening of the Second Avenue Subway.

The basis of their report was a presentation that was made last Monday to the MTA's Capital Program Oversight Committee (CPOC) by the MTA's Independent Engineering Consultant (IEC) Kent Haggas.

The presentation that Haggas made to the MTA's board started out by saying that, "The IEC is unable to verify the project's reported 102 days of schedule contingency."

According to DNAInfo New York,
"The [CPOC] report noted that equipment rooms at the 72nd Street station are two to three months behind schedule, and that there have been been substantial delays in getting permanent electricity to all of the stations. Only some of that delayed time has been made up for by the MTA’s recent attempts to expedite the project, he said.

Haggas also said that about 25 issues engineers asked the MTA to address in December 2012 are still unresolved, and now there are dozens more."

DNAInfo New York went on to report that a spokesperson for the MTA "insisted that the overall project is on schedule to open in December 2016".

The following updated ancillary building renderings were included in the MTA's presentation to Community Board 8's Second Avenue Subway Task Force Update on Monday June 23rd.

These ancillary building will house the modern day systems -- such air tempering and ventilation equipment -- that are required for new subway stations.

The exterior design for each of these buildings has been a "work in progress" since the earliest concepts were presented to The Second Avenue Subway Task Force back in 2007.

One could assume that these updated renderings now represent final designs.

Here are two artist renderings for Entrance 3 of the 96th Street station. The first rendering shows a design from 2008; the second rendering shows the design as of 2014.

The new design now includes a set of stairs that must be climbed before descending into the station on an escalator.  Most likely these stairs were added to the design in a post-Hurricane Sandy review of current and future subway entrances. This particular entrance is on the edge of the Zone 1 flood zone for New York City.

And here is the final image for this posting.

Yes, this is a Second Avenue subway tunnel.

Southbound Tunnel - looking N
ca. June 2014

This tunnel at 101st Street, which now appears to be almost complete, was originally constructed in the mid-1970s by a joint venture of Cayuga Construction and Thomas Crimmins Contracting.

The tunnel is being renovated and brought up to current standards as part of Phase I of the Second Avenue Subway project.  

You might wonder what this tunnel will be used for, since the last station stop for Phase I is 96th Street. It will be used to store out-of-service trains until Phase 2 of the project is built at some future time.

New 2nd Ave Subway Exhibit Opens


Have you ever wondered about the construction techniques being used to build the Second Avenue subway?

Now you can learn more by visiting the MTA's Second Avenue Subway Community Information Center (CIC), which recently unveiled its new exhibit: En Route: The Techniques and Technologies Used to Build the Second Avenue Subway.


Metropolitan Transportation Authority / Patrick Cashin
5/23/2104

Twenty images from the opening day of the exhibit can be found in this link:
CIC Exhibit

The second of the CIC’s biannual exhibits uses interactive and static displays to demonstrate 13 of the construction technologies used to build the Second Avenue Subway.

Techniques such as tunnel boring, controlled blasting, cut and cover excavation, air scrubbers, and ground freezing are explained through photos, videos, and animations in an interactive exhibit using iPads to control wide screen displays.

An entire wall of the CIC displays a cross section of the project from 63rd Street to 104th Street to illustrate the bedrock profile under the surface and the techniques used to cut through it and excavate above it.

A virtual tour of the 86th Street cavern and tunnel is included in the new exhibit. Also part of the exhibit, the CIC showcases two new models: a replica of the tunnel boring machine and a scale model of the 96th Street station.

Want to learn more? Visit the CIC to see the exhibit first hand:

When:
Mondays, Wednesdays and Fridays from 10 a.m. to 6 p.m.
Tuesdays and Thursdays from noon to 8 p.m.
2nd Saturday of each month from 11 a.m. to 3 p.m.

Where:
The CIC is located at 1628 Second Avenue, between 84th and 85th Streets.
The nearest subway stop is the 86th Street station on the 4/5/6 Lexington Avenue Line.

Admission:
Free

Fewer Than 1,000 Days to Go!


A significant project milestone occurred this past weekend: there are now less than 1,000 days until the start of revenue service for Phase I of the Second Avenue Subway. (*)

As a reminder, Phase I of the project is the extension of the existing Q Line service to the Upper East Side, under Second Avenue, with new station stops at 63rd, 72nd, 86th, and 96th Streets.

To mark this milestone, I have added a new web widget to the right-hand column of the blog to count down the days until the start of subway service.



(*) The MTA's current forecasted Revenue Service Date for Phase I of the project is December 30, 2016. This date can be found on page 5 of the MTA Capital Construction's 4Q2013 Quarterly Report for Phase I of the Second Avenue Subway project.


Here are the number of days that have passed since a few other key historic milestones (as of today, April 8, 2014):

929
The number of days since the Tunnel Boring Machine (TBM) completed the second of two tunnels for Phase I of the Second Avenue Subway, on September 22, 2011.

2,553
The number of days since the official ground breaking for Phase I of the Second Avenue Subway, on April 12, 2007.

3,652
The number of days since the Final Environmental Impact Statement for the Second Avenue Subway was approved, on April 8, 2004.

4,765
The number of days since the "Notice of Intent", for the Second Avenue Subway, was published in the Federal Register on March 22, 2001.

6,872 +/- 15 days
The number of days since the Manhattan East Side Transit Alternatives Study was released, in June 1995.

15,766
The number of days since Governor Rockefeller and Mayor Lindsey broke ground for the Second Avenue subway on February 7, 1971 (during an earlier attempt to build the subway).

30,902
The number of days since the New York Times ran its first story about the Second Avenue Subway, on August 30, 1929.
