Back on Track, from Québec


Even while on vacation the Second Avenue subway project has a way of finding me.


8/30/13

I was in Québec, Canada for part of August and, completely by chance, I came across a tunnel form structure (shown above) that will be used for the Second Avenue subway project.



8/30/13

I first noticed this structure in Ayer's Cliff, Québec, when I was  visiting the Annual Exhibition of the Stanstead County Agricultural Society (also known as the Ayers' Cliff Fair). The village of Ayer's Cliff is located just 10 miles north of the Vermont border.



8/30/13

A few days after the fair closed, I drove back to Ayer's Cliff with my camera. Hoping to introduce myself, and take some pictures, I dropped in at the office of Everest Equipment Company.

To say that they were a little surprised to meet me might be an understatement.

The project manager told me that they had received so many questions about this particular tunnel form that they had decided to post a large sign on it that explained to passersby what it is.

The tunnel form shown here is for use inside the 86th Street station. This structure, which is technically known as a "station arch tunnel formwork," will allow the contractor to cast complete sections of the 86th Street station cavern ceiling arch using concrete.



8/30/13

The company began designing and fabricating the tunnel form in January of 2013. Assembly of the form structure began a few months later in the company's yard.

After the tunnel form has been inspected by the customer, who I assume is the MTA's contractor Skanska / Traylor JV, it will be disassembled and shipped to New York, and then reassembled inside the 86th Street station cavern.

This piece of the form is a section of ceiling arch turned on its side.

This is a view of the tunnel form, as seen from the grandstands on the Ayer's Cliff Fairgrounds. (The tunnel form is in the center of the image in the distance -- double click to enlarge the image.)

A Footnote

My apologies for a lack of fresh postings during the past three months. After blogging about this project more than six years I decided to take a break for the summer.

I'm back now and ready to renew the effort.

Giving Credit Where Credit is Due


The MTA's staff photographer Patrick Cashin has been capturing the progression of the Second Avenue Subway project since 2009 through images that the MTA has been posting on Flickr.

He recently talked about his work in this short video that was produced by the folks at Flickr:

Lots of Progress at 86th Street


Patrick Cashin, one of the MTA's staff photographers, captured a nice set of images of the 86th Street station cavern earlier this month. As the images below clearly show, there has been a lot of progress underground at this location.

I believe that this is a view of the south end of the cavern. The two tunnels, which were excavated by the tunnel boring machine in 2010 and 2011, are partially hidden from view in this image.

The photographer is now standing at (under) the northwest corner of 83rd Street and Second Avenue. This street corner is the future location of Ancillary No. 1 for the this station.

The duct work on the roof is part is part of the air handling system.  I believe that one of the ducts is used to provide fresh air for the cavern and the other duct is connected to the air scrubber unit at this corner. (The scrubber unit, which is at street level, is used to remove dust and other particles from the air before it is exhausted into the open air.)

Worker Rescued from Chest-high Mud


As reported by numerous media outlets, a construction worker on the Second Avenue Subway project was seriously hurt yesterday evening after he became trapped in chest-high mud between 95th and 96th streets deep under Second Avenue.

According to the news website DNA.info, 155 first-responders raced to the scene at about 8:30 p.m. on the evening on March 19th to begin a major operation to rescue the worker. Some four hours later, the half-submerged man was finally freed from the mud and transported to New York-Presbyterian/Weill Cornell Medical Center with hypothermia.

Based on an earlier conversation I had with a contractor, it seems the worker may have became stuck in a soil material composed of varved silt -- or as it is commonly called, "bull's liver", by some contractors in New York City. Varved silt was deposited in the New York City area by ancient glacial lakes that once existed in the region.


Earlier today, the MTA posted on their Flickr page a set of stark images that were taken after the incident. A few of these images are posted below.
