I was down at xtreme structures talking to them about the roof
system they are buying. Tim, their rigging guy told me to always make sure the contract had a disclamer in there, saying if the winds reach over x amout then the roof is comming down, if it gets windyer than pull the covers off. I have learned to always anchor to a good "
ballast". A good
ballast consists of at least 5k lbs or a suitable stake. Many companies use barrels full of water, when ever possible i tie off to our 24' trucks. If I was the production company, I would at least
drop the roof down to a lower
level. (it looks almost like they did, but the winds continued to blow the rest over). I guess they arent too worried about saving their gear, if it were me i'd have it all covered with tarps or something. I did a show a while back and I knew we were going to get rain, but the people kept praying that this little spec of no rain they kept showing on the weather
channel would stay over us. Naturally it did not, i ended up cutting a big hole through the roof, to keep the water from pulling the roof down. We had already lowered it. Never again am i taking those chances. I ended up having about 40 moving lights and a
dimmer rack go swimming. (the
dimmer rack was completely submerged, the moving lights had water pouring out the fronts of them) Luckally after the storm blew through, and a ton of hair dryers, I was able to save the show.
