When was algo centre mall built
In particular, the expansion joint above the escalators, the failure of which appears to have caused the roof deck collapse, was already not properly binding to the concrete, in turn allowing water to seep into the building's seams, as early as —barely a year after the mall's original opening.
The expansion joint was fixed many times, and fully replaced twice, during the building's lifetime, yet always began tearing away from the concrete again shortly after the repairs were complete. The inquiry did not question or raise concern with the areas of slab removal during original construction in when escalators were installed after the roof was completed.
It is unclear if this was a contributing factor. Soon after the collapse, the owners arrived at the mall.
A representative spoke on behalf of the owner, stating "I'd rather not comment, because we have talked to our lawyers and we're going to be in the City Hall to represent ourselves. But nevertheless, we are very much concerned about this accident. By approximately pm, local authorities alerted the Commissioner of Community Safety, Dan Hefkey. The HUSAR crew, after assembling their equipment and travelling the kilometres from Toronto, arrived by am Sunday, June 24, and immediately began work.
In the early hours of Monday morning, June 25 — and despite discovering signs of life — rescue work was suspended due to the danger of additional concrete falling on the potential survivors and the HUSAR rescuers. Following the announcement, numerous residents of the town began to sign a list volunteering to enter the structure themselves to continue the search; the owners also announced their intention to seek a court….
Map Hotels Places. History Algocen Realty Holdings Ltd. Structural problems By , the mall was already regularly plagued with leaks and water damage. We do not have results related to Algo Centre Mall. Auberge Eldo Inn. Lakeview Inn. It underwent a partial structural failure on June 23, , when a 12m x 24m 39'-by' segment of the rooftop parking deck collapsed into the building, crashing through the upper level lottery kiosk adjacent to the food court and escalators to the ground floor below.
More than 20 people received non-life-threatening injuries and two people died in the collapse. An investigation and class action lawsuits into the collapse are ongoing and the mall has been demolished. The city of Elliot Lake formally purchased the vacant former Algo Centre Mall site in , as the first stage in a process of redeveloping the land for new residential and commercial uses.
Marie, began her testimony Thursday morning in the Crown's case against Robert Wood. Ladell told the court she had become increasingly nervous about the shopping centre's structure.
She testified she felt "exasperated" about cracks in the drywall, leaks and ceiling damage that "appeared to be changing. Ladell started to document her concerns, photographing loose brick in some areas and problems near the lottery kiosk where the collapse finally happened. She said she even stopped using that entrance area. In the early hours of Monday morning, June 25 — and despite discovering signs of life — rescue work was suspended due to the danger of additional concrete falling on the potential survivors and the HUSAR rescuers.
Following the announcement, numerous residents of the town began to sign a list volunteering to enter the structure themselves to continue the search; the owners also announced their intention to seek a court injunction ordering the resumption of search and rescue efforts. HUSAR later stated that the rescue teams were continuing to strategize alternate methods during the work suspension, and that the local residents and the Premiers call did not influence their actions.
Shortly after 10 p. The area which collapsed included two kiosks. The deceased had been a lottery kiosk employee and her customer.
Lucie Aylwin, 37, worked just once a week at the lottery booth, earning extra money for her wedding. Aylwin held a full-time job with College Boreal, a French language college, as an employment consultant and recruiter in the colleges Employment Options Emploi office, located elsewhere in the Algo Centre Mall. Doloris Perizzolo, 74, was a widow and mother believed to be opening pull-tab lottery tickets, which must be opened in view of the booth operator. After the bodies of the two victims were retrieved, and HUSAR confirmed no other victims were trapped in the rubble, efforts shifted to official investigations.
The investigation found that the collapse was caused by a two-stage failure of the welding on a connection, due to extensive corrosion. The corrosion was caused by improper waterproofing and the placement of a parking lot on the roof, which allowed water, contaminated with road salt, which accelerated the corrosion to corrode the structure. The report states that there were two critical errors made during the planning stages.
Firstly, the parking lot for the mall was located on the roof of the building without there being sound waterproofing, and secondly the structural inefficiency of the hollow-core slabs HCS which prevented the installation of effective waterproofing later on.
John Kadlec of Beta Engineering originally planned the use of 8-inch HCS, which he specified could withstand pounds per square foot, a load which exceeded specifications on all 8-inch HCS. During the bidding process, the owners were advised by a bidder, Precon, that the specified load could not be handled by the HCS without reinforcements from a composite concrete topping.
However, Kadlec advised the owners that the plans called for 8-inch HCS which could withstand the load without reinforcement from topping. In , over a decade after the malls construction, Coreslab retracted the claim to be able to support the load without the use of a composite topping.
Two different waterproofing systems were proposed to the owner by Harry S. Peterson Co. The first system called for a rubberized asphalt membrane to be applied over the non-composite concrete topping, while the second one called for no membrane, and simply controlling leaks with a polyurethane sealant. HSP argued strongly for the second option, and convinced the owner to install the second system.
The report called this system "intrinsically flawed", and leaks were noticed immediately after construction. Leaks were noticed immediately after the installation of the topping. Harry S. In , the owners contracted Trow to investigate the chronic leaking and find a solution.
Two options were provided, but upon consulting with Coreslab, it was determined that neither plan could go forward due to the HCS not being able to support additional loads.
These leaks allowed water to seep through the topping and access the steel frame of the building. This corroded much of the buildings frame during the malls three decades in operation.
The corrosion was eventually so severe that the weld on a connection failed, resulting in the collapse. John Kadlec, a consulting engineer on the original construction, has testified that he raised concerns at the time about sloppy workmanship and inadequate construction materials at the site, including structural columns that were already crooked, steel beams that were already rusting despite being new, and the ultimately fateful decision to place the complexs parking area on the roof.
According to Kadlec, the construction company opted to resolve the structural issues not by redoing the construction, but by anchoring the buildings back wall to the rock outcropping behind it. James Keywan, the buildings original architect, testified that he also strongly objected to the rooftop parking, but had little choice once Algocen made their decision to proceed with that plan.
The son of the malls owner admitted that the company had pressured engineers to remove information on leaks and corrosion from a report and that fictional repair invoices from a shell company, Empire Roofing and Restoration, were used to mislead mortgage holder Royal Bank of Canada about the buildings condition.
Speakers at the inquiry have also testified that a significant volume of city traffic regularly cut across the roof deck as a bypass of the traffic lights at the corner of Hillside Drive and Ontario Avenue, resulting in more stress on the structure than it had been designed to handle. The NORR report speculated that a heavy vehicle might have contributed to a previously undetected partial failure of the support structure a few months prior to the final collapse.
The inquiry also found that while Perizzolo died almost instantly, Aylwin may have survived for up to 39 hours after the collapse, and may have been found alive if HUSAR had not suspended its rescue operations. The province and the National Fire Protection Association denounced the cuts.
The Canadian Centre for Emergency Preparedness suggested that such cuts would necessitate Canada asking for assistance from the United States in similar situations. Also cancelled by the Conservative federal government was the Canadian Emergency Management College, established in to train first responders.
A spokesperson for Public Safety Minister Vic Toews deflected criticism of the cuts, noting that 90 per cent of emergencies are managed municipally or provincially. As of the end of June, the economic impact of Algo Centres closure was unknown, but described by Mayor Rick Hamilton as "huge". Estimates suggest people worked at the mall or hotel.
