DEMOLITION | Francis Scott Key Bridge Collapse Truss Separation | 4K VIDEO
00:00 Intro
01:07 Prep Work
04:50 Demo
At 1:28 AM on March 26th, the container vessel, MV Dali, lost power while proceeding south on the Patapsco River out of the Baltimore, Maryland Harbor. The starboard shoulder of the bow impacted the southern channel pier of the Francis Scott Key Bridge causing collapse of the pier and progressive failure of the entire 2,640’ long continuous truss that spanned the two (2), 720’ wide approaches and the 1200’ wide main channel that accommodated vessels having up to a 50 draft.
The collapse of the bridge tragically caused the deaths of six (6) workers performing maintenance on the bridge deck and resulted in the closure of one of the busiest ports in the US, putting an estimated 4,000 port employees out of work while impacting another 15,000 Baltimore residents who relied on port activities for their livelihood.
The City of Baltimore, State of Maryland and Federal Government immediately joined forces toward reopening the channel as quickly as possible under a Unified Command structure led by the US Army Corps of Engineers. The Federal government assumed responsibility for clearing debris from the 1200’ wide main channel, Skanska was tasked with debris removal responsibilities outside the main channel and Resolve Marine of Fort Lauderdale, Florida was retained by the ship Owner and its Operations Company to remove debris that had fallen on the bow of the ship and to salvage the vessel.
Resolve Marine retained Controlled Demolition, Inc. (CDI) to design, perform preparations for and carry out explosives separation of the 600’ long southern portion of the channel-span truss from the bow of the Dali.
The bridge truss, pier cap and roadbed debris fell vertically onto the bow of the vessel and the continued motion of the ship caused the truss to twist, adding additional stored energy to the already compromised bridge truss system. CDI’s scope to separate the truss from the ship included preparatory pre-burning operations that would identify and then cope with the stored energy in the box configuration and other truss elements that had flange thicknesses up to 4” thick to be severed with explosives. Strain gauges and other monitoring devices were installed to provide real time readings on truss stability so that pre-burning could be paused as necessary to ensure CDI employee safety.
CDI’s goal was to provide a 60’ wide space between the vessel and the remaining truss, in the water, while rolling as much of the truss as possible off of the bow of the Dali during the explosives initiation sequence. The presence of flammable materials in containers damaged by the bridge collapse necessitated cold cutting for preparation of shaped charge locations where hot work couldn’t be safely performed. Cold cutting could not be completed on all elements above the bow due to the energized truss elements, leading to a plan that would leave a small portion of the truss on the bow and other truss elements draped over the port side for post-blast crane removal.
Preparatory burning was carefully monitored by CDI and structural engineers and the sequence/nature of pre-burning was changed several times following twisting observed in bridge elements during torch work. Working out of 185’ manlifts and crane baskets proved challenging on the water due to wave action, winds and weather that limited working hours. Even as they otherwise prepared to re-float the vessel, Resolve Marine provided marine platforms/equipment to support CDI’s operations toward removing the truss from the Dali as quickly as was safely possible.
A total of 162 pieces of Linear shaped charge explosives were placed at 52 locations with a NET explosives weight totaling 312.69 lbs. of RDX and PETN explosives to create the separation between the truss and the vessel and to permit as much of the truss to rotate off the bow as possible during the blast. Conveyor belt at-source protection was placed by CDI to control the fly of debris from the detonation of the explosives charges.
Once the Unified Command cleared the CDI specified Exclusion Zone around the blast area, Resolve Marine turned on a water fire suppression system over the damaged containers at the bow to mitigate risk of fire.
The Dali crew was sheltered below decks at the stern of the vessel in a soundproofed area during the blast while Resolve Marine and CDI employees positioned themselves at the stern of the vessel during the explosives detonation. The non-electric initiated blast had an integral 9.6 millisecond delay directing the pressure bar away from the vessel and the windows in the bridge which represented the most sensitive element to remain on the vessel.
The charges were detonated at 5 PM on May 13th. The separation was completed, and that portion of the truss intended to roll off of the bow, did so, exactly per plan. There was no reported damage to the vessel, or its cargo and no fire was initiated on the vessel as a result of CDI’s operations.

Atlanta-Hartsfield Air Traffic Control Tower Demolition
When they hang the conveyer belts they're using a Hilti powder actuated ramset nail gun that uses .27 caliber blanks to drive nails into steel and concrete . CDI usually uses the conveyor belting to wrap the linear shaped charges to prevent debris being launched at mach 9 in all directions. I'm assuming they're just hanging them over the charges on this job
4:12 onwards, they are using the nailgun
Bro the tower crash the underwater 🥶
Pues bueno, la verdad es que me he quedado impresionado con la estructura del puente, es una obra gigantesca de metal, todavía no lo puedo creer y es algo muy complicado, más de lo que parece o se nos enseña. Pero como a todo profesional, no se le puede dar un 10 de golpe y porrazo, por qué se dormirían en los laureles y eso no es bueno, pues no le deja margen de error y de lo que se trata es que sean o no los mejores, todo tenemos cosas que aprender siempre, no somos perfectos y por ese mismo motivo. Supongo que lo digo por algún detalle visto y que supongo que se subsanará con esa experiencia y por eso mismo no voy a decir error, sencillamente por que quizá ellos ya se habrán dado cuenta. En su lugar o decir algo que no es ningún error como se ha dicho, les propondré quizá una sugerencia o algo que les pueda el quizá llegar a obtener una nota más alta? Claro está, la publicaré en otro lado... en donde? Que vida ésta, que sea más jodido... que la voladura de un puente.
😱😰😨😮
I want a house made by the same guy whole made those boilers.
Somebody built it. Somebody can unbuild it.
I so called it!!! On "What's going on with shipping" channel, when he reported that they were going to employ explosive cutting to free the Dali, I posted "There is only one _family_ that can pull this off, *_The Loizeaux Family_* is who they are going to call." I was so right, then again, who else? The Loizeaux's are the best in the world. When its the most complex, the most treacherous, the most high profile, the most important, requiring absolute precision, and when failure is not an option, there is only one phone number you dial. It's always CDI. Well done, as always!!!!! God Bless the workers who perished.
Great job with the green buildings at the top. Virtually unscathed all the way down. Amazing! 👍 I expected to see all kinds of green metal rubble, thinking what a clean up that will be. Just one question - why not have the chimney fall into the same pile as the plant? Would make for a lesser area to clean up. TIA
Loud but pretty good👍👍😊
I would love to see the after report: where you expected it to go, where it actually went, and how that changes your placements in the future. In this case, it really came down to best case engineering stresses and modeling on where to place them, but how close were they? Fantastic and safe work! Thanks for the behind the scenes!
As usual, this is beautiful. Love each video. The music played on this video, is exceptional. Thank you!
This one made me cry a little. It was a piece of Americana.. who didn't love getting their Sears Wishbook catalog for the Christmas season😢
Great job guys!👍
Amazing video to go with amazing work! Really gave me the insider feel, like I was seeing some privileged views of the event that few others have access to. Thanks so much for that. I could have done without the "epic adventure" music, but at least it was timed well.
Whoa! Reset! I want a reset. Rewind my life 40 years so I can work for you. That's a job that's different every day, work outside alot and never gets old! That has GOT to be so satisfying!
"The sea was angry that day my friends, like an old man trying to send back soup in a deli."
Cdi try released all your old videos demolishing old structures outside america like compilation
Excellent job and great production!
I was wondering if this was your work when I heard they were blowing it.
Great production. I really appreciate leaving the music out while the demolition itself is happening, really good stuff!
super
So sad too see history being blown up
Awsome work as always with CDI. True artists at work...Always callled to the toughest challenges. Always amazing.
This whole situation has been so interesting to me. I knew they would hire THE BEST. Thanks for showing us the prep!
1:04 VROOM!!!
I guess I should have known you guys were the ones who did the demolition.
Of the cooling tower are they get old Will be demolished of has abandoned
Weeks ago in a discussion with another engineer, I commented it'd make a lot of sense for coveniently local CDI to be part of that salvage. It seemed like politicians were bloviating an awful lot about Army Corps, which has some serious resources, but they're not CDI.
No, the ACE are NOT CDI,,,,,,,but then neither is anyone else👍👍👍
As fast as the project is moving, I'd say there are some terrific leaders and incredible technicians at scene. CDI has done amazing work for a very long time.
Probably your best video yet! The drone shots were superb, and showing how everything was prepared was really interesting. CDI, you always do a bang up job (pun intended)!
Precision steel cutting and structural demolition, first thing which came to my mind... CDI. Too bad the media coverage never mentioned it and the way they spun things implied that it was going to be the Army Corp of Engineers who would be doing the work and maybe using military demolitions teams.
3:16 That came way too close to smacking the replacement bridge on the way down!
4:19 Kinda reminds me of Buster Scruggs walking into the cantina and patting himself on the chest, leaving a dust outline of himself when he walks away.
when this ship hit the bridge... I posted on facebook. "they knocked it down faster than the TheLoizeauxGroupLLC" look who got hired to get it off the ship .
I mean, who else could you call. These guys have done work a few miles from my house and I live in a small town in the north east of England. CDI baby!!!! Oh yeah.
BOOM
great work CDI
CDI is the only company to put trust in when in dire need of demolition. They really do a BANG UP JOB [yes pun intended} have a blessed day.
poor bird..
oh damn that first water tower is historic 🤣 no more I guess
Amazing work under such circumstances and conditions
Your team have done a great job again to safe the ship out 💯 also RIP to the 6 workers 🫡
cool stuff
Job well done! Thank you for answering the call, documenting your response, and sharing it in the most detailed, tactful, factual and respective manner. Loizeaux Group & CDI are the best and a total class act.
A big thanks to CDI / The Loizeaux Group for this footage! Everyone who put this video together and all the workers did a brilliant job! A very impressive presentation for certain.
CDI the demolition expert indeed
@6:11 that bird went full overdrive
I feel sorry for the people waiting for stuff in the containers that got pancaked
