The London municipality must do a full review of permits and compliance with building codes in this construction site. They need to make sure that no more workers or future residents are in danger here. I would hesitate to live in this place, even for free.
This sad incident has unnecessarily cost lives and injured workers just trying to make a living and go home healthy to their families. I trust the engineers who designed the structure were present at the site prior and during the pouring of the concrete roof to inspect, and ensure everything was safe because they are ultimately responsible and should be accountable if there were any design flaws or negligence regarding this unfortunate incident.
@@paulo5258 should have used a hollow core material instead of poured concrete. Old dangerous methods like pour concrete floors are dangerous and must be eliminated
Appears like very little structural support (no concrete columns, concrete load-bearing walls, solid steel columns walls seen) to handle the weight of a heavy concrete roof. Some developers are moving away from full concrete load bearing walls for low-rise buildings and replacing with light gauge steel or wood in the construction of the condos in accordance with the building code, which is good for them but not so great for the condo owners because the common structural elements are easier to compromise. The Ontario Building code needs to be changed to stop this method for multi-storey residential buildings and go back to time proven poured concrete structure method.
Please do not comment on the type on building materials used in projects, especially this one, without knowing about those products and their capabilities. The cause of this failure is unknown at this point. Furthermore, CIP concrete buildings have failed in the past, which has caused fatalities.
@@paulo5258 but your comments aren't based on any knowledge or experience in the construction industry, or the type of materials being used on that project. Basing your opinion over what the LFP says is the problem. They are not experts either, and the entire story of what happened is still unknown. As an example, they keep saying the workers were in the process of pouring the 4th floor, but by the pictures, they were pouring the roof. It might not seem like a big deal, but when the little and obvious details are wrong, I'm not going to believe they got the bigger issues correct. Ferro Engineering has been called in to help with the investigation, and he still isn't sure what went wrong. So how do you, someone with out any knowledge, know what happened, but one of the most experienced PEng's with this system still doesn't?
@@charlisantini3403 What are you talking about? "I didn't mention workers were in the process of pouring the "4th floor "so please get your facts in order. BTW...Engineers have close working relationships with suppliers, builders and municipalities therefore an inquiry is required to find out what caused this tragic incident.
@@paulo5258 I'm talking about you making claims about the type of material that was used in the project without having any knowledge about those materials or the process in which they are used.

3rd World construction in the shell left of Ontario's high principles. This might seem rant-like but isn't. The province and municipalities allow this shoddy workmanship to happen. When structures built on sound design fail you drag the engineers, superintendent, foreman and city building officials to answer to investigators. When tin can 4-storey shitboxes are approved for building you throw them all out. The error trail leads to their door. Sound engineering and design doesn't collapse. Negligent construction does. Metal stud and metal joists to shore up concrete that weights 150lb cu.ft. should be criminal, and the roof joists, as the pictures show at 0:07, are unsupported, almost facade-like. The load has to translate straight to the foundation and there is no appearance of any. This concrete roof is like stacking a book on a house of cards. The beams used, middle pic, bent and twisted, are pop can. The investigation has just started. The failure mechanisms haven't been officially defined. But part of that roof dropped the better part of 4 storeys until couldn't drop any more. One roof support area fails and sets off an instant chain reaction. A section of the recently poured concrete roof, with workers on, opens up in a split second and plummets down into no resistance floor after floor. The gypcrete pan floors were cardboard to the descending mass. Ripped in two down the middle or torn off the mounts. Pan floors should put up a resistance and arrest the descent. These didn't because London, ON has no building standards. All concrete pour collapses start with failure in the forms below. Something failed in the 4th floor and the affected section of the roof chain reacted down and met zero resistance, blowing the walls out. There would be a loud bang sound and roar, the workers plunging maybe 35' into the pit, followed by screaming and mayhem. Concrete is used with steel post & beam for proven reasons. When builders skimp metal for steel this catastrophe happens. These workers, most young, that elect to go in these flimsy junk piles are sadly inexperienced with safe engineering concepts and too many engineers in Ontario, spoken from builder experience, are shit useless. Greedy builders, bad engineers, unethical public servants and idiot politicians dilute the building codes into the danger zone. The lawyers sue all three back into compliance when things get out of control. It's a yo-yo process. Today, London, ON is 3rd World building. Once the lawyers are done with these dorkballs, the yo-yo will switch back to where it should be.
A CFS panel can be engineered to be stronger than a heavy steel post and beam structure. But hey, sideline QB, tell us all about a topic you know nothing about
@@charlisantini3403 Which part of cold-formed steel _panel_ is column, joist or bracing? Panels are corrugated decking and only fall if something below fails, like happened here. In this video ruclips.net/video/jvhJhhsyg_s/видео.html the plastic deformation of C-joists, the corkscrew effect, is visible. These are under-gauge, non-braced, flawed installation. POS material, engineering and workmanship. If you know anything about the cost- and space-saving gimmick CFS, every horizontal, vertical, lateral and diagonal component must be 100% structurally sound before the pour and factor of safety to handle the highest predictive wind loading, snow, rain and human loads. This couldn't handle the concrete.
@@jasonbell5152 you should go check out iSPan's website before you start commenting on what material was used in the building and how it went up. CFS was used on the wall panels, which is a very common, and very strong building product. iSpan uses their own Total Joist system with a metal deck similar to what is used with OWSJ system. The concrete was poured on top of that. If I was to take your approach, and believe what I heard about the incident from the media, then the problem was with the deck, not the metal studs. And just so you know, anytime you lay a flooring system, whether it's a poured deck of on a type of joist, or a hollow core product, the structure below needs to be sound, horizontally,, vertically, laterally I diagonally. How about you wait and see what caused the failure, before complaining again that the old antiquated way of putting up buildings is being shoved out of the way for a more modern and efficient approach
@@charlisantini3403 lfpress.com/news/local-news/partner-in-apartment-that-collapsed-lost-licence-to-build-new-homes It's iSPAN[sic], and I don't know if this company's products were involved, and judging from the c-joists, don't appear to. New buildings collapse because they're built wrong, unprofessionally. Shaun Stevens, the partner in Brock Construction, builder of this apartment building, had his builder license and Tarion membership revoked for building shitboxes, like this one in London, ON. See any similarities? I don't know what you're trying to defend or why you're using a ditzoid transgender person's pseudonym.
@@jasonbell5152 I can tell you 100% that iSpan, a company owned by the Walters Group located just off the 403 at the Princeton turnoff, was the supplier of the CFS wall panels, and Total Joist system. I know this because their sign is on the fence along the property, 3 Total Joists are clearly visible in the video shot just after the collapse, and oh yeah, I know the union company who iSpan uses to install their product, and they have told me they were involved in the project, with guys I personally know being on site the week this happened. And oh yes, the engineer who has been called in to review the site has been on a number of my jobsites as well. This would go a lot smoother if you realized that you know just a little bit of info, but nowhere near enough to be making the comments you are making. Although over complicated and far too time consuming, iSpan's system is safe, when engineered and installed properly. It is very, very unlikely that the cause of the incident was the fault of the system, but most likely human error, which is sadly what is the cause of the vast majority of situations like this, no matter the product. If you want to put the blame at Shaun Stevens' feet, go ahead. But it would seem plausible that if you are going to blame him, the same situation would happen no matter what the building product is used. So again, human error not product error. However, , I still maintain that despite some of the problems it causes, hollow core is a better product to use. Should have called Stubbe's instead on this one. I guess you must know you aren't doing well here, considering your last comment, I would suggest you just keep this to the facts and situation at hand, but when you're on the losing end, this is what happens. Sad.
