Improving Second Avenue


The MTA decides that it is time to clean up Second Avenue

This surprising announcement, which was announced on the MTA's web site over the weekend, describes a wide-scale overhaul of the MTA's work sites between 69th and 100th streets on Second Avenue.

In their announcement, the MTA said that they have created a "comprehensive set of 'good neighbor' standards to upgrade the physical conditions around the construction site to improve the pedestrian experience, and keep businesses and residences fully accessible."

Some of the planned improvements include:
  • Implementing "way-finding" signage for stores that is uniform, legible and clean
  • Ensuring sidewalks are in good condition without holes, cracks, and trip hazards
  • Replacing bent/worn fencing
  • Painting all barriers
  • Maintaining sidewalks, crosswalks, and safe sight lines for pedestrians/vehicles
  • Maintaining full access to businesses/residences

According to the NY Post, the president of MTA Capital Construction, Michael Horodniceanu, ordered the makeover after hearing many complaints from business owners and residents during several trips to the construction site. "These are simple things that will make people happy, so people can actually be in that area and not hate every day they live there," Mr. Horodniceanu told The Post.

According to Tom Namako's story in The Post, the MTA will begin by upgrading the area between East 92nd and East 93rd streets.

The MTA posted these two images on their web site as examples of what the sidewalks in the construction zone might look like before and after the refurbishment.

What is somewhat odd is that this initiative was not raised or discussed at the recent Community Board 8 Second Avenue Subway Task Force meeting on October 12th. This would have been a good opportunity for the MTA to obtain community input on the aesthetic changes it would find most valuable.

Ironically, the MTA's announcement came on the same weekend that a group of affected Second Avenue residents and business owners staged a rally to protest the conditions in and around the construction zone.

The rally was held on 91st Street between 2nd and 3rd avenues. The protesters cited, among other complaints, 'three years of neglect and delay' and the absence of real government support.

A few images from the rally are shown below:

I asked a number of people at the rally why they thought the MTA had decided to take action to clean up the work site now, three and a half years after the start of construction. The most interesting answers were:
  • Perhaps the MTA was reacting to the news that the residents and business owners in the affected area would be holding a rally, for the media, to protests the conditions;
  • Possibly the MTA realized that they needed take a fresh look at what they were doing after the The New York Times ran this front page story on October 5th;
  • Maybe this issue will be brought up at next week's MTA board meeting and the management at MTA Capital Construction wanted to be able to announce something prior to the meeting of the board;
  • Or perhaps Mayor Bloomberg is moving into Gracie Mansion.

Here are a few notable media reports from the rally:

In other news - construction work continues.

The following set of images was taken over the past two weekends, on the dates noted.

The contractors continue their work in this area as they prepare for freezing the ground south of the launch box. (see the diagram below)

According to the MTA, the ground must be frozen in this location because the rock to be mined is unexpectedly poor. (Freezing makes the ground totally solid so the Tunnel Boring Machine [TBM] can bore right through it.)

Failing to freeze the ground could increase the likelihood of gripper problems at the face of the TBM. And because the sound rock cover above the tunnel area was found to be insufficient, this could increase the risk of tunnel collapse during the mining operation.

The contractors plan to start freezing the ground in this area by the end of November, so that it is solidly frozen before the TBM starts mining the east tunnel in early 2011.

The approved cost for the ground freeze operation was reported on the MTA's web site to be $6,582,000.

The following set of images was included as part of the presentation that S3 Tunnel Constructors made at last Tuesday's meeting of the Community Board 8 Second Avenue Subway Task Force.



The photographer here is looking south towards the front of the Tunnel Boring Machine (TBM).

Don't worry - the tracks shown here are not intended for the new subway line. They are for the muck train that transports the rock from the TBM mining operation back to the launch box in the 90s.



This is an image of a locomotive that is hauling a set of muck cars out of the rear of the TBM.



The passing switch shown in this image (which is located just south of the launch box) allows one muck train to pass another.



The muck cars are moved into the launch box and then they are positioned over a transfer pit.



The contents of each muck car are then dumped onto a set of conveyor belts that transport the crushed rock to the so-called muck bin, pictured below.






The muck bin, which is located near the north end of the launch box, is a location where the crushed rock is stored until it can be transported to street level for loading into trucks.

Here's a copy of the Second Avenue Subway MTA Capital Program Oversight Committee Report that was posted on the MTA's web site in anticipation of Monday's meeting of the MTA Board Committees.


MTA Capital Program Oversight Committee Report
Pages 33-40 (Second Avenue Subway)
10/2010
(Note that this report is part of a large PDF document on the MTA's web site, so it may take some time to load.)

This interesting report was prepared by the MTA's independent engineer McKissack+Delcan.

The report says that the project is on schedule to meet the December 2016 revenue service date and the project is on budget.

The reports listed three specific issues that, "may lead to cost increases or schedule delays on individual milestones of contracts". They are:

Quoting from the report...

TBM Mining Tunnel No. 1
Issue:
The original plan to finish TBM Run #1, with the extension to 65th St was January 15, 2011. The revised date based on a mining rate of 43 feet per day is February 15, 2011. Recent 20-day average has been 44.4 feet per day.
Impact:
If TBM Run #1 is delayed beyond February 15, 2011, critical path float will be used. TBM mining must average 43 feet per day to meet this date.
Mitigation:
Contractor has instituted a special scheduled maintenance system to minimize breakdowns or slowdowns of the conveyor system and muck removal operations.

Litigation 72nd Street Station
Issue:
Litigation contesting MTA's compliance with the environmental commitments made in the project Environmental Impact Statement (EIS) has been initiated by the owners of a residential building located adjacent to the planned site of the 69th Street 72nd St ancillary facility for the 72nd Street Station.
Impact:
FTA has determined that the proposed changes to the design of this facility are consistent with the project EIS. A court hearing on this matter is scheduled for January 2011.
Mitigation:
The work impacted by the litigation has been segregated as an option to provide time for resolving the legal action.

Fragile Buildings along Second Avenue
Issue:
Older, fragile buildings near the site of station and ancillary building (e.g. vent plant) excavation, many with pre-existing deficiencies, may require remediation as Second Avenue construction continues.
Impact:
Temporary resident relocations and exterior and interior remediation work required in the area of the future 96 Street Station. Potential for similar impacts at the sites of the future 72nd Street and 86t Street Stations and the 63rd Street
Station. Costs to date have been within estimates and are manageable within available contingency funding.
Mitigation:
Survey of fragile buildings was segregated and advanced independent of future construction contract awards in order for remedial work, if necessary, to be completed in advanced of actual construction start dates, Surveys will be completed by the end of 2010. Contractors to do remedial work, if necessary, have been identified. Both these steps will allow MTACC to progress and fund any needed work so that it minimizes adverse impacts to cost and schedule.
