It was hot in the city on Friday evening, for the middle of November, so I decided to go for a walk and take a few pictures of evening work location at the NW corner of 93rd street and 2nd avenue.
The crew that was working at this hour was digging a trench for part of the slurry wall that will become the west side of The Launch Box.
All of the pictures that follow were taken using the
Sepia tone setting on my camera.
One of many pedestrians that stopped to observe the activity.
The crew here is digging a 70 foot deep trench using a piece of equipment called a Diaphragm Wall Grab.
The Grab is lifted, and lowered, into the trench using one of the big Liebherr crawler cranes - as shown in the image above.
The crane operator has just lowered the Grab deep into the trench.
And now the Grab has just been lifted out of the trench, with the bucket at the end full with a load of earth and rocks.
Another view of the same work location -
this time looking south down 2nd avenue.
The liquid that is falling off the Grab, as it is being lifted out of the trench, is a mixture of water and bentonite. The hole is full of the water & bentonite mixture to prevent the collapse of the trench.
The soil and rocks from the bottom of the trench are dumped by the Grab into a pile, and then loaded into a truck to be taken away.
I left the site at about 9 PM, as the crew kept working.
