Caisson work goes full bore at 354 North Union

There are few things construction nerds look forward to more than caisson work. It marks the unofficial “official start” of skyscraper construction, people are digging in the dirt, heavy machinery dances around each other, and loud noises bounce off neighboring buildings. You might not think it’d be fun to watch, but it’s mesmerizing. Which is why some of us stand there and take dozens of photos.

Last week marked the beginning of caisson work at 354 North Union. Big shout-outs to Stalworth Underground and Onni Group for providing the entertainment. Here are dozens of photos:

The stage is set for Caisson Theater at 354 North Union

Caisson setup at Onni Group’s 354 North Union

The actors know their lines, the set is decorated, and the curtain is about to go up at 354 North Union. The Stalworth Underground Drill Team has been standing by patiently waiting for their moment to shine. That moment is now. Let the caissons begin!

354 North Union is a go

Site prep, 4/12/2021

Site preparation is underway for/at 354 North Union, a 32-story, 373-unit apartment tower in the Fulton River District of West Town.

354 North Union got its first permit way back on March 16 of 2020, giving developer and general contractor Onni Group the all-clear to start building the foundation up to the “underside of level 3.” The Pappageorge Haymes Partners-designed tower will also include 143 parking spaces, if that building permit is to be believed.

Check out the two Stalworth Underground big blue rigs sitting off in the corner, champing at the bit waiting to drill caissons deep into the earth. Bit. Drill. Heh.

This was 352 North Union at the community meeting six or so years ago. I think it went up a couple ticks because it’s taken so long to get it started. But we’re here, that’s what counts. A forthcoming new name wouldn’t surprise me though.
