February 21, 2009



near 91st

The work site, from 91st up to 95th, has been swarming with activity over the past few weeks. If I had to guess I would say that they're working extra hard to finish the surface work on the west side of 2nd Avenue so that they can shift their work back to the east side of the avenue.

The road decking on the west side of 2nd Avenue now appears to be complete, from 91st up to 95th -- and most of the work is taking place just beneath the street level, on the west side of the avenue.

The contractors are installing a new 48"(?) water main (a section of this pipe is shown above and below.) They are also working to secure the utility lines to the underside of the decking. This is being done so that the contractors can excavate the Launch Box to it's full depth of 70 some odd feet.

A view of the stone drilling machine at work. I believe that it is being used to install so-called mini piles, for the foundation of the launch box.



Another view of the same machine. (Too bad I can't also include the sounds that it makes!)



93rd, NE corner
This drilling rig has been working near this location for over a week now. In the past this rig was used to drill out core samples of the rock below. But now they're just drilling down through the rock, without collecting samples of each core. My guess is that there is a section of bedrock down below that needs to be "softened up."

A nice example of the road decking above what will become the launch box for the tunnel boring machine.

Hello, thanks for doing this site..do you know where (which street) the actual muck/dirt/rocks (dont know what else to call it) from the TBM will be excavated to trucks and hauled away? thanks

I've been told that the excavated rock and soil are being used to fill in a rock quarry somewhere in Pennsylvania.

thanks, but do you know what street 91st or 96th street or somewhere in between on 2nd ave the excavation point will be? just curious...

Ben said...

I have no idea where exactly they will take the rock out of the launch box, once they start tunneling.

But, if the diagrams in the MTAs presentation decks (for CB8) are still accurate, then it looks like they will bring the rock to the surface somewhere near 93rd street.
