DEMOLITION | Hart Island Chimney

- Опубликовано: 7 мар 2023
- Located on the East River, a half mile off the Bronx in New York City, Hart Island’s somber history includes facilities that were used as an institution for the mentally ill, a tuberculosis sanatorium, a boy’s reformatory, a drug rehabilitation center, and a prison. For that entire time, part of the island was, and continues to be used as a “potter’s field” for burial of low income and unclaimed New York residents. The island has been described as the largest cemetery in the United States and the final resting place for over a million individuals since 1864.
Gramercy Group, Inc. (Gramercy), was retained by the New York City Department of Design & Construction and LIRO Engineers, Inc., to demolish the remaining structures on the island, including the structurally unsound, 1912 vintage power house chimney that had been modified and damaged over the years to the point where Gramercy had concern for worker safety under both hand or mechanical demolition options. After deciding that an explosives felling of the 135’ tall chimney would be the safest means of bringing the damaged structure to grade, Gramercy contacted Controlled Demolition, Inc. (CDI) of Phoenix, Maryland, to assist in the demolition of the Hart Island Chimney.
After working closely with Chief Inspector Joe Meyers of the New York City Fire Department Explosives Unit to issue permits for the project on a fast-track basis, CDI mobilized to the site and used proven methods to protect personnel from potential fall of debris from above while preparing the severely damaged chimney in just eight (8) working hours. On the morning of January 30, 2023, CDI safely felled the damaged chimney without disturbing burial sites as close as 100’ from the fall path of the chimney.

I hope someone saved a picture of the beautiful pattern in the brickwork at the top. That’s not seen anymore.
I love the obligatory court-ordered water stream that's absolutely nowhere near where the dust is blowing XD
With that big crack down the side I'm surprised it was still standing! 😳 Great job as always, guys!! 👍
Good thing you guys were there, looked like it was ready to fall down by itself
Yes! A mild hurricane or heavy downpour would've toppled it if not for the brave folks at CDI!!
The sound effects and smoke were added. It was actually 10 guys sneezing on the stack simultaneously...that brought it down. You can't fool me.
Wow a proper brick chimney Fred Dibnah would've been proud to take down. Looks like it was so badly cracked that it would've come down by itself anyway!
Old Fred was the first person I thought of too! May he rest in peace!
And another project is excellently executed 💥 Must mention that the drone photography has improved by leaps and bounds 🎬
Wow - that had gone well beyond its ''sell by'' date!
Nice drop (or - 'shock induced collapse!') :)
Imagine working at the bottom knowing at any time a loose brick from the top could come crashing down. hard hats a must.
That chimney was ready to fall on its own, y'all did it a favor and brought it down safely
"It looks like it could fall at any minute. Go attach these explosives to the base."
"No, _you_ go attach the explosives to the base."
That island has one interesting history.
Wow, it looks itself very fragile and dangerous with all these cracks!
Jeez that came down quick and really nice 😳 you make it look so easy, but it's really hard! Proud of your work CDI!
Such an interesting place to be doing a job. Also wow, that was a rather giant crack up the side. I'm glad they were able to prep the job so quickly to minimize risk.
I wonder if there will ever be a completely remote demolition option available (in countries that have safety standards, anyway), like flying (potentially) sacrificial drones up to the side of a structure to attach explosives.
Brilliant job as always.
Great coverage , imagery , and editing ! A wonderful production !
My Great Grandfather was a Yankee POW imprisoned on Hart Island @ the very end of the War of Northern Aggression. Fortunately, he was captured during the last week of the war, & didn’t have to suffer through a Northern Winter like so many had to. He was paroled in mid June 1865, returned to his home in South Carolina, & promptly moved the family to Arkansas.
It is one of my dreams to spend two or three weeks walking over & retracing the very ground his unit traversed in each battle. I know I can’t get onto Harts Island itself, but want to look over the bay to it from City Island.
I watch all these videos. Thanks ! 💜
PERFECT!! As normally done by CDI. Drone shots are also GREAT.
It is not in great shape so you did it a favor by bringing it down
Sure do like the drone view!
Yes, that brick work is indeed a lost art!
Thank you CDI for another great vedio.
It was great that you provided such great background information of this chimney. It well written and prevented me from Googling to get this information after watching the video. It was also somber that so many folks are buried there that were never claimed.
The production on these keeps getting better and better. Keep them coming!
Amazing it was still standing given the deterioration shown in the initial drone shots!
It has an interesting pattern in the brick, but yikes, that crack!
This company is amazing
I wonder how many masons it took to build that chimney?
Nice! Classic mid-column buckling.
FYI: Hart Island was a prison but it is home to "Potter's Field" (AKA City Cemetery, Hart Island Cemetery), a graveyard with many unmarked graves due to the inability to identify people at the time of death, e.g. homeless people.
Disney star Bobby Driscoll (Song of the South, voice of Peter Pan) was found dead at age 31penniless and alone in an abandoned East Village, New York City tenement and was buried on Hart Island. He's still there to this day.
Maybe. After so much time has passed, I would think they start to reuse the same land to bury more bodies. As grim as it is to say, there can't be much left.
A few comments. Beautiful smokestack, but quite damaged. Your knowledge of structural engineering always shows in the flawless execution of your demolitions. The quality of the production and image quality is amazing. Thanks for some great entertainment.
How it stood as long as it did I'll never know.
Looked delicate as shet!
Nice shot.
I would not like to have been the guy at the base of that stack who was doing the drilling unless there was a good protective cover.
Such a shame to see these old brick men fall. No one will ever build them again.
3:02, I'd thought they were going to make use of that three wall foundation pocket for containment.
Great job. But miss the woompf because it broke up as it came down.
1:43 Fire in the hole!
1:45 TIIIIIIMMMBEEEEEEEEERRR!!!
Imagine if this chimney could talk, what sights it has beheld, especially at night
The Chimney was on it's way out, but it's sad so many other historic buildings were ripped down without a thought of saving them or just fencing them off. Were the bricks or other artifacts/architectural elements saved?
I wonder what they have planned for the site once they get the buildings cleared? That chimney was in BAD shape! Looks like a strong wind could have took it down. Next time, for laughs, run the film in reverse.
Probably more graves.
There’s no doubt it was in terrible shape and needed demolition. Great job.
That chimney was seriously cracked. I'm surprised it was still standing. It really needed to come down.
Given the condition of this chimney, it's a wonder that it hadn't already collapsed onto itself.
Hopefully many of the bricks could be saved and collected for other buildings or restoration projects.
Nice
"Yeah, baby!"
Could've given it a good kick, to make it fall!
It looks like that stack had been struck by lightning, missing brick and crack from top to the ground. Another great job by CDI.
Did everyone get to keep a brick as a souvenir?
Oh boy. It's easy to see why this one had to go^^
😮
Probably the easiest job in a while. Still fun to watch.
👍👍👍👊👊
Thanks for watching!
It looked in very poor condition, so just as well it was felled before it did so itself!
I would be pooping my panties just standing near that thing in its condition. Hats off to the brave souls who got the job done!
That water mist does not seem very efficient. Has anyone ever used explosives in large tubs, bladders, ponds etc.of water to saturate the air with fog when a structure comes down?
