A New Schedule


Here's a copy of the new schedule for
the MTA's Second Avenue subway project -


(left-click on the image for a view that is readable.)

The schedule above was presented by the MTA at the last meeting of the Community Board 8 (CB8) Second Avenue Subway Task Force on September 24th, 2009.

For comparison purposes, I've also including a copy (below) of the last full schedule that the MTA presented at a CB8 Second Avenue Subway Task Force meeting. (It was presented over three years ago on July 11, 2006.)




When you compare these two schedules a number of interesting things become clear:
  • The MTA's proposed in-service date for Phase I of the Second Avenue Subway has now been set for December 2016. (it was late 2013 in the earlier plan.)
  • The overall amount of time that has been scheduled for the construction of Phase I has increased from 7 years and 1 month to 9 years and 8 months. (an addition of 31 months)
  • The scheduled duration of Contact 1 (Launch Box, Tunnels and shafts at 69th and 72nd Streets) has increased from 37 months to 51 months. (an addition of 14 months.)
  • All of the other contracts have had a significant amount of scheduled duration time added to them too - with 5 to 30 additional months added to each of the 6 major parts of the project.

The project is taking much longer than planned for a number of reasons. These reasons most likely include:
  • On Contract 1 it took them much longer than they imagined to relocate the maze of utilities under 2nd Avenue in the TBM launch box work zone;
  • Contracts have been awarded later than planned (e.g. Contract 2A, 96th Street station Site Work & Heavy Civil - the Request for Proposal was issued on 3/7/08 but the contract was not awarded until 5/8/09)
  • Important parts of the final design were delayed because the final location for some of the station entrances are still being reviewed. (in particular the entrances for the 72nd and 86th Street stations.)
  • Delays related to the acquisition of certain pieces of real estate.

I'm sure that there are many other reasons, and in time they will become known - when the MTA Inspector General publishes his report on the project.

And as a final note, it's important to remember that this schedule depends on the allocation of about $1.5 billion to the project, in the yet to-be-approved 2010-2014 MTA Capital Program.

S3 Tunnel Constructors also made a presentation at the same Second Avenue Subway Task Force meeting.

In their presentation they includes 4 pictures of the work that is on-going underneath the road decking that covers the TBM Launch Box. Here are copies of those pictures:

October 4, 2009




Here are a set of images that I captured during a walk that I took on Sunday afternoon, October 4th. I started my journey at 101st Street and walked south on Second Avenue to 68th Street.

As many people are aware, there are now 4 active subway construction zones on the Upper East Side:

95th to 100th Streets,

91st to 96th Streets,

82nd to 87th Streets, and

69th to 73rd Streets.



100th Street - in the middle of the avenue - looking S

The contractors have now setup a protected walkway (for pedestrians) in the middle of Second Avenue between 96th and 100th Street.

This will allow them to close both the sidewalk and the roadway, on the eastern half of 2nd Avenue (at this location), so they can prepare the surface area for excavation work.



96th - the middle of the avenue - looking N



just S of 96th - looking W
(this is a stitched panoramic image of this location.)



btw. 92nd and 93rd - looking W

This red clam shell bucket appeared on the work site about ten days ago.

I assume that they must now use a bucket, attached to a very large crane, to lift the soil from the bottom of the pit because the excavating machines on the surface can no longer reach the bottom.



93rd - looking S

The contractor recently covered the signs [in this area] that warn passersby about blasting operations in the TBM launch box work area.

The signs have been covered since no blasting is currently scheduled, at least until the FDNY issues a blasting permit.



btw. 83rd and 84th - looking E

This notice, behind the orange protective fence, is an announcement that the bus stop at this location has been discontinued.

A number of M15 local and express stops on Second Avenue have recently been temporarily moved or discontinued by the MTA due to the subway construction.

A complete list of the effected M15 bus stops can be found on this link.



btw. 84th and 85th - looking W

Here the contractor is just starting to erect protective fencing for the work zone in this area.

One could assume that these trees will be saved - since they have had wooden protective boxes setup around them.



84th - SW corner - looking S

The contractor has established a work zone here (on the left of the orange barrier) with a 7' walkway remaining. (on the right of the barrier in this picture)

Unfortunately it is not clear to some people that they should not walk through the work zone.



83rd - NW corner - looking N

A better example of people walking through the work area. (on the right of the orange netting.)



btw. 83rd and 84th

A goofy image of the work zone, as reflected by a mirror that was setup outside a shop in this block.



69th - looking N

Here the the entire east side of the avenue is closed off as they work to relocate utility lines and pipes in this area.

1766-1768 Second Avenue / 301 92nd Street
(posted on the front door)

And now we come back to the story of the building that was evacuated back on June 29th because it was in danger of collapse.

The fragile condition of this building has, so far, prevented the MTA's contractors from obtaining the necessary FDNY permit for blasting work in the south end of the TBM launch box. (See this earlier posting for further details.)

This Department of Buildings (DOB) permit says that the contractor intends to "install steel channels on the north, east and west exteriors, connection channels to the joists through the walls, and connecting the joist to the intermediate wall." In other words, they are securing the exterior walls to the floor joists in the building.

The obvious goal of this work is to secure the building's structure so that:

(a) the DOB can remove the Full Vacate order on this building, thus allowing the residential and commercial tenants to move back in, and

(b) the DOB gives the okay to the FDNY so that they issue the necessary permit so blasting can begin in the TBM launch box.

What is very interesting to see is that the work permit to S3 Tunnel Constructors - the joint venture company that was hired by the MTA to build the Second Avenue subway TBM launch box.

Apparently S3 Tunnel Constructors is also acting as the general contractor for this work. (A copy of the work permit application, from the DOB web site, can be found on this link.)

Ever since this building was evacuated back in late June the MTA has maintained that the structural problems [with the building] at this address pre-date the start of the construction of the Second Avenue subway -- and the violations that the DOB issued to the building's owner, 1766-68 Associated LP, prior to the start of construction support this claim, to some degree.

The MTA also has said that the vibrations caused by the subway construction work met building standards.

But to be fair, one must not overlook the reports from residential tenants who live(d) in this building. One report, which was left as a comment on this blog, said that during the subway construction work caused cracks in the walls to get got longer, door frames to stick, and the commenter went on to say that, "... the vibrations from construction have been unrelenting and overwhelming."

So this leads me back to a simple question? Why is the MTA's contractor, S3 Tunnel Constructors, acting as the general contractor for the work to repair this building -- when normally it would be the responsibility of the buildings owner to make any necessary repairs.

A Footnote:

Some people have asked me why I don't have any pictures of the work that is taking place underneath the road decking over the launch box work area.

The simple answer is that I don't have permission to enter any part of the work zone.

I did send a written request to the MTA about ten days ago, requesting a "very limited amount of escorted access" to the launch box work area for the purpose of taking photographs for this blog.

After due consideration, I was told that that my request had been denied by the MTA.

Instead they offered to invite me, along with other members of the news media, to the next Second Avenue subway related "press event."

September 30, 2009


Here's a copy of the Second Avenue Subway Project "Report Card" that Congresswoman Carolyn Maloney, State Senator Liz Krueger, Assemblyman Micah Kellner and City Council Members Jessica Lappin and Dan Garodnick released on Friday, September 25th.

The "report card" gives the MTA an overall grade of "B-" in connection with its performance on the project.

QUOTE

Congresswoman Carolyn Maloney
Second Avenue Subway Report Card


On April 12, 2007, the Metropolitan Transportation Authority (MTA) celebrated the most recent groundbreaking for the Second Avenue Subway. At the time I expressed the wishful hope that the fourth groundbreaking on this project would be the charm. And it still may be, but there’s been a lot of sobering news since we celebrated the subway line’s most recent resurgence.

At groundbreaking, the plan was for the subway line to be completed in 2013, with three tracks at 72nd street and at a cost of $3.8 billion. Today, the MTA and the Federal Transit Adminstration (FTA) are discussing whether the subway will open in 2016 or 2018, projected costs are now estimated at $4.4 billion and we’ve lost the third track. Meanwhile, construction is having a dramatic impact on local businesses, residents and traffic. Roughly two and a half years into construction, it is time to take a look at the project and see how well the MTA is doing. Just as the City has found that report cards help evaluate the schools, this report card is intended to gain a better understanding of how the MTA is doing in moving forward with construction. This is a mid-term report, and the MTA has plenty of time to make up for early deficiencies.


WHAT'S BEEN WORKING

Project Merit: A+

All the reasons that led the FTA to consider this project one of the best in the nation remain strong factors. The subway will relieve overcrowding on the Lexington Avenue line, which continues to be the most overcrowded subway in the nation. When it is completed, it is expected to carry roughly 202,000 passengers a day, more than any other new start project in the nation. New Yorkers continue to rely on mass transit to commute to work, more than any other area of the country, and the Second Avenue Subway will provide much needed capacity on a system that has not grown in more than half a century.


Economic Benefits: A+

The Second Avenue Subway is creating 16,000 jobs, most of which are well-paid union jobs. At a time when the construction industry is slowing down, infrastructure construction like the Second Avenue Subway provides a vital source of income for thousands of construction workers. It has generated $842 million in wages and produced $2.87 billion in economic activity. Economists like Mark Zandi tell us that every dollar spent on public infrastructure increases GDP by an estimate $1.59. Using that formula, the Second Avenue Subway will generate nearly $7 billion in GDP.


Communication with the Public: B+

The MTA has held numerous public hearings during the environmental review portion of the project, and before property takings were approved. The MTA has also worked with Community Board 8, and other community boards, and has participated in Second Avenue Subway Task Force Meetings at least quarterly. As construction moves forward, they have agreed to attend meetings as frequently as monthly. In addition, the MTA has attended frequent meetings of the Second Avenue Business Association, and has worked with the City to mitigate impacts relating to sanitation, signage, traffic, utilities disruption and other matters. The MTA has hired Claudia Wilson who received plaudits at a recent Community Board 8 Second Avenue Subway Task Force Meeting for her availability and her willingness to solve individual problems. The MTA has also been willing to meet with local residents to resolve individual concerns relating to particular buildings. Nonetheless, despite these efforts, many community residents seem to know little about the project until construction begins in their neighborhood. Further, some details have not become public until it was considered too late to address the problem. For example, residents of buildings adjacent to ancillary facilities are being told that their windows will be covered by the new buildings. The likelihood was long known, but the MTA never told the neighbors until the designs were finalized.


WHAT NEEDS IMPROVEMENT

Planning: B-

The Second Avenue Subway is a complex project, and it requires a lot of coordination to bring all of the elements together. It is surprising, therefore, to find that there has been so little progress in two and a half years. Anyone with experience in New York City’s streets knows that there are few roadmaps for utility pipes, and that there are surprises. The MTA says it lost several months on the tunnel launch box because of where utilities were located. Delays of this type should have been expected and built into the schedule. Further, the MTA should have investigated the structural integrity of local buildings long before masonry started falling. If there had been better coordination between the MTA and city agencies, blasting would not have been delayed in order to allow adjacent building to be appropriately shored up. All of this should have been done much earlier in the process.


Construction Management: B-

The MTA is working on many large projects simultaneously and it needs to ensure that this project is getting the attention it deserves. The 7 train extension (which does not need federal approvals and is being constructed in a less dense area) began long after the Second Avenue Subway, and the tunnel boring machine is already in the ground. The MTA has recently taken steps to pull up its grade by getting permission of the MTA board to allocate federal funding so that contracts can be bid more quickly. It has broken contracts into smaller chunks to allow for more competitive bidding to bring costs down. It has created a schedule of contracts so that the public can follow its progress to make sure that contracts are being bid on time.


Mitigation of Construction Impact: C

The MTA seems to want to try to mitigate the impact of construction on local residents and businesses. They have been diligent in meeting with local businesses. They have hired people who genuinely appear to want to work with the community to address individual concerns, and some members of the community have complimented their efforts. They have reduced the number of buildings they have condemned to limit the number of people who will be losing their homes. They have created a Shop Second Avenue campaign to try to drive customers to affected businesses. Unfortunately, more than a dozen businesses have closed along the subway’s construction zone despite these efforts.


On Time Record: C

When this project went into Final Design, the MTA was projecting a completion date of 2012. By the time the project broke ground, they projected a completion date of 2014. This summer, the MTA began projecting a 2016 completion date. Some argue that the project will not be finished until 2018. Others suggest that the MTA could get its act together and move forward more aggressively, finishing earlier than December 2016. There’s a lot of room for improvement here.


Staying on Budget: C

When the full funding grant agreement was signed, this project was supposed to cost $3.8 billion. Today, the MTA is projecting $4.4 billion. It’s not going to be easy to find the extra funds, particularly when there are so many other competing projects. The longer this project takes, the more it will cost. The MTA is taking advantage of the dip in the economy to bring some of the costs down, and it has scrapped plans for a three track system to reduce costs further. But unless the MTA meets its projections, it will be very hard to find the resources to complete this project.


Progress Toward Completion: C-

Thus far the MTA has bid 3 of 11 contracts. It has completed some of the preparatory work for the tunnel launch box, including building the slurry wall, but no blasting has begun. Thus far there has been no tunnel dug, no shafts completed, no station entrances built, and no ancillary facilities built. It’s early in the project and preparatory work does need to be done before we should expect to see tangible results. Two and a half years into construction, we hoped for greater progress.


FINAL GRADE

Overall Grade: B-

The Second Avenue Subway is crucial to the economic future of New York. It needs to be built. The MTA has an ambitious construction schedule, and it needs to put its full attention to making sure that this project is moving forward with all deliberate speed. Up until now, the project has been marred by missed deadlines, cost overruns and a harsh impact on local businesses. There is a lot of room for improvement, but also the possibility that the project is now starting to gain momentum.

And here's a link to the story that Pete Donohue, of the New York Daily News, filed last Saturday, September 26th, on the report:
"2nd Ave. Subway May be Delayed, Again, and Gets B-minus in Report"

In the story the Daily News also reports that the MTA Inspector General's office has now opened an "all encompassing" review of the delays and cost overruns.

One could assume that the MTA's Inspector General got in to the act after Manhattan Borough President Scott Stringer released this press release - back on July 22nd when he called for the Inspector General to, "open an immediate investigation of what has caused this latest delay."

In other news,

The MTA confirmed, at last week's Community Board 8 Second Avenue Subway Task Force meeting, that plans for blasting inside the TBM launch box are temporarily on hold.

They have also posted this notice on their "Construction Look Ahead" web page:

QUOTE

* CONTROLLED BLASTING UPDATE *

Controlled blasting activities are temporarily on hold due to stabilization work that is required to correct pre-existing structural deficiencies in buildings located at 1766/68 Second Avenue. Controlled blasting activities will begin once the New York City Department of Buildings has determined that the required stabilization work has been completed. This work is expected to be completed by the end of October. During this time, rock excavation will continue by mechanical means and all current contracts, including the two recently awarded contracts, will continue to proceed.

When blasting activities are ready to occur, we will post signs and follow the procedures outlined above.

Here's a link to the story that Jessica Simeone and Tom Namako,
of the NY Post, filed on September 25th:
"Second Ave. On Snail Rail: Shaky Bldgs. A Drag On Dig"


The two problem buildings are 1776-68 Second Avenue and 1772 Second Avenue.

The mixed-use building at 1776-68 (also known 301 East 92nd Street, since the building sits on a corner) has been empty since it was evacuated by the NYC Department of Buildings back on June 29th because it was in danger or collapsing.

The Department of Building's Vacate order on 1772 Second Avenue was partially rescinded on August 14th. This action allowed all of the residential tenants to return to their apartments, after being forced out for two months.

September 23, 2009

Here are two short videos that I found on YouTube of work inside the Tunnel Boring Machine Launch Box (i.e. underneath the road decking) in the 90s.

I'm going to assume that these were taken by one of the contractors on the work site.
