The Metrodome in Minneapolis collapsed at 5:30 this moring. They had 18" of snow during the storm and the roof couldn't handle the weight. Todays game is to be played tomorrow in Detroit. I already have tickets and hotel for next weeks MNF game against the Bears so hope they can fix it quickly, otherwise out about $500.

I am not an engineer by any means but wouldn't the heat from the building just keep the roof warm enough to melt the snow as it is falling? And if the snow was coming down too fast for it to be melted by said heat then who came up with the brainy idea to build a stadium with an inflatable roof in one of the snowiest regions of the country?

Yea. Seems like kind of a strange design but has only collapse once before and only took 4 days to fix. I believe the roof is made of some kind of teflon fabric and has a pretty good slope on it so snow seems to not typically collect on the roof. They don't usually get that much snow at one time, it was said to be the worst storm down there in 20 years.

With it being inflatable I'd assume it would have 2 sides and have a pocket of air with the bottom acting as a shield. So Maybe all the heat wasn't getting all the way to the top layer? :thumbs:

 

 

 

Anybody notice the audible POOF when all the snow hit the field? I think that's the most amazing part of it. Hate to think what the outcome would've been had this happened during the game. :thumbs:

It would have been awesome if the snow dumped right on Bret Favres head. Let's see if he can get up from that one....

I was wondering why don't they have a heating element in the roof to melt snow when it falls. You would think they would plan for a getting a lot of snow.

The roof has 2 layers and they were blowing hot air in between to try to melt the snow but it could't keep up. Maybe this is what it takes to get the Vikes a new stadium. The Metrodome is about at the end of its usefullness.

Or at least a new roof, which is probably why they did not take drastic measures to try and melt the snow off.... Because their insurance is going to buy them a new one....

      Thanks!  I figured as such; GM and other manufacturers have used standard parts and harnesses across trim levels and such for decades.  I pulled the blank accessory cover off of my commuter van (a 2016 or so Chevy 15-passenger) years ago and found the plug for a USB outlet.  It wasn't connected to anything, though (I tried swapping in an outlet from another van).  I was a GM Tech years ago (late-90s) and was pretty familiar with my 2006.  I might be wrong, but I view newer vehicles (pretty much anything made in the past 20 years) as being a lot more plug and play.  Meaning, more unused wires and plugs unless you have the Mack Daddy of vehicles.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.
