Back on Track, from Québec
Even while on vacation the Second Avenue subway project has a way of finding me.
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.
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.
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.
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.)

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.
