“Snow on the roof was probably heavier than the design loads”

A visual examination suggested remedial welding was not up to standard.

Worksmanship blamed for stadium roof collapse
Inadequate workmanship, the low expectations of the old building code, and unusually heavy snow contributed to the collapse and ultimate destruction of Stadium Southland, the findings of an independent review committee say . . . They recommend plans for the new stadium be peer reviewed before construction and that it is accompanied by a quality control programme, but steer clear of apportioning blame or establishing the legal responsibility.

Insurer NZI and the Department of Building and Housing are also investigating the collapse, and the National Institute of Water and Atmospheric Research is preparing a report on the snowfall.

    Elizabeth; Shades of 26th July 1939. Could it happen again? Too right it could.

    It’s the 3rd roof collapse at that stadium.
    Definition of insanity: doing the same thing over and over expecting different results.

  4. Allow me to correct you, this is actually the 5th time this particular roof has deflated or collapsed due to massive snowfalls or extreme weather, the same bloody roof.

    This would be a collapse of a roof without a metal structure holding it up. Completely unrelated to the design faults of Stadium Southland. And of course nothing even remotely to do with ForBarr Stadium.

    An inflatable roof is vastly different to what we have in NZ. And I can’t remember the last time we had 2FEET of standing snow in Dunedin.

    Definition of boring is moaning about the same thing over and over but being completely wrong about it.

      US stadium roof collapses after heavy snow
      AP
      The inflatable roof of the Metrodome sports stadium [has] collapsed after a snowstorm that dumped 43cm on Minneapolis.

      The Metrodome roof is 4ha of Teflon-coated fiberglass that is supported by 20 90-horsepower fans. It weighs roughly 263,000kg.

    I agree with you, Paul. Tales of massive snowfalls on a daily basis tend to grow like fishing legends. The reality of history is much less exciting. The EFTE roof cladding is not a load bearing material, and is not intended to be so. It is the curved form of the roof structure which will desperse snow and the like. A pointless exercise to compare this structure with other structures using different materials and techniques.

  6. Just as aside here is the inflated dome roof of the GM Place stadium being deflated before dismantling and the whole stadium is redeveloped. The GM Place stadium roof was of similar construction method to that in Minneapolis. The weird thing is when you open the doors to the stadium the air comes gushing out – quite literally.

    The redevelopment itself is stunning and is changing the skyline of downtown Vancouver dramatically, but one of the lasting images I have of Vancouver is that big white dome you could see from miles around.


    And a quick look at what BC Place is being transformed into:

    Of course we don’t need to worry about anything bad happening structurally as Malcolm Farry has said ‘not even an act of God’ could destroy our stadium. He said this, you will remember, after the Southland stadium collapsed after a snowfall. What’s that about tempting God?! Malcolm’s The Man. I feel so much better. Don’t you?

  8. Brilliant, someone has a video of what the air pressure is like leaving these domes. This is the exit to the Metrodome. I can’t remember leaving GM Place it being that strong, but it was fun. Throws up all sorts of accessibility issues eh.
