Just thought I would share some pics of what my typical Saturday night has been for the last year.

We are a year into a $60 million project to build a new ventilation plant for the MTA on 30th St. between 6th and Broadway.

Enjoy. Feel free to ask any questions

BTW. All this steel was set by hand by my four man crew and myself. Besides being set into the hole with a crane, everything was moved by hand using chainfalls and come-a-longs.

Notice that the tracks of this machine are completely buried in mud.

I really get a kick out of this. This is a 50 ton telephone manhole that is being suspended in the air by a total of 10 1-1/4" rods.

Manhole view from the bottom.

Really the only thing holding this up are the threads on these nuts!

Just how high is this thing in the air? BTW: The lower pipe strut in this pic is 25 feet below the street.

Steven those photos are great. I have no idea what I'm looking at in most of them :) But I like them.

what is a telephone manhole? (please no obscene jokes) and why does it have to weigh 50 tons??

Jon,

A telephone manhole is the generic name for a communications manhole. It's an underground concrete vault. These two are 14'x10'x14'. The walls are 12-14" thick concrete. There are over 60 4" pvc ducts run into this manhole. You can see all the PVC that's wrapped in saran wrap.

There is a company called ECS (empire city subway), they "own" pretty much all the communication manholes in Manhattan and the ducts that carry wiring. They rent these ducts to the utility companies. These ducts carry telephone, cable TV, fiber optic, even the line for the fire alarm boxes.
