While the disaster took the public, and thanks to New Media, the World, by surprise, featuring a dramatic video of the action as it happened, a document that is the meeting notes from the
"Regular Meeting of the Metropolitan Sports Facilities Commission" Thursday, July 15, 2010 at 9:30 a.m this blogger obtained online and is linked to here reveals that the roof was inspected in April of this year by Birdair, the roof maker. Before I continue, here is that video:
In a report to the Metropolitan Sports Facilities Commission, which manages and obtains financing for the Metrodome, Birdair explained that the roof should be replaced, and that while it's outer fabric "is performing well as compared to the original fabric specification," the inner membrane "has exceeded its service life of 20 years."
The stadium is 28 years old and the roof has collapsed four times over that period, including Sunday's disaster.
This part of the Commission report is particularly troubling:
Birdair also noted the inner liner is dirty and has some holes in it. Birdair recommends monitoring the areas with holes to avoid large tears from enlarging. Birdair rated the inner liner’s condition fair to poor. In addition, Birdair noted some minor areas on the outer membrane that needed repairing. Those areas have been repaired by staff.
What this means is, taken as a whole with both inner and outer membrane conditions, the roof was not in good condition, and had "large tears" that could enlarge. Apparently, under the weight of a tremendous snowstorm, they did. Moreover, it's not clear to what degree the condition was worsening in the time between the inspection in April and the roof collapse of Sunday.
Finally, Birdair recommended roof replacement, stating "As in the prior inspection report of five years ago, Birdair suggests the Commission consider planning for replacement of the roof fabric." In other words, the roof has been in a state where it needed to be replaced for at least five years, and the Commission was aware of it.
Birdair also attached an estimated cost to replace the roof at $12 million to $15 million, and said that it took five years to plan and implement a roof replacement.
With all of that, staff of the stadium believed the "roof continues to have serviceable life and will schedule testing again in another four years." Or, the Metropolitan Sports Facilities Commission was willing to just have the stadium operate with the roof in condition where it needed to have been replaced long ago.
Until Sunday's events, that is.
Now, the stadium is arguably unsafe to be in, and even though work is underway to make the stadium ready for the planned ESPN Monday Night Football Game pitting the Vikings against the Chicago Bears, next week, given the events, will patrons want to watch the game under a roof that just collapsed the week before?
Stay tuned.
Imagine if that would have taken place a few hours later, while the game was in progress. Companies like to cut corners to save money, and it usually costs them a lot more in the long-run.
ReplyDeleteyah its very bad that the damage to the roof caused the cancellation of several events, and Vikings game against the New York Giants, to be moved to Detroit.
ReplyDeletethey suffer a lost by this disaster.
