Kinda off topic, but I am looking for someone who has done this or knows someone who has done this- i am looking to construct my own quonset ( arch ) type storage building after the Christmas light season because we are going to be out of space to store folks' lghts and wreaths and stuff. I have a 2700 square foot building that is 8 foot at the sides and 12 feet at the peak, The roof leaks in spots and has water damage at some wooden framework, so it is time to redo my storage situation rather than just add on if I can help it. the pad I have is 60ft x 90ft, with 30x90 already built on by the current building. my plan is to buy a 60 x 100 x 25'tall Straight leg type quonset, that goes up a straight wall about 6 feet before going to the traditional half aluminum can shape. The first 10 feet of length will be simply to porch cover the doors and provide some attractiveness to the front face, which will be sided with a color vinyl siding to coordinate with the doors. the other 60x90 will be closed in. The new building will cover the old building and then we will tear the old one down from the inside once we move all the stuff to the new, taller part of the building. There are lots of reasons i want to go with the arch type: I believe I can build this while I don't believe I can build an I-beam structure, It is quite less ( 30%-40% ) expensive by square foot or cubic foot compared to the I-beam, and it requires much less concrete for footers as the roof load and walls is spread equally over the entire length of the wall rather than on beams. further, they are hurricane ( cat. 2-3 ) tornado ( 125 mph ) and heavy snow ( 36lb ) rated. why am I posting? I want to find someone else who has done this and ask them how hard it was, and how long it takes. I have found some videos on youtube, and looking at the videos, it kinda looks like building with al dente noodles until the arches are up and bolted to one another. at that point it is strong. but until then I fear that the arches could fold up on you or bend in the wind. anybody have any experience at this?
