For a 24' diameter 5/8 3V the lengths line up with 10' pipe lengths, vertex to vertex - the OP has that down. That's ~83 lengths of 10' pipe and some spares. Home Depot online $180 1/2", $359 3/4". About 2x difference. Save costs by ordering as a contractor at an electrical supplier.
EMT weights 30 and 46# per 100 ft for 1/2 and 3/4. So 260# and 399# total assuming the tubes extend 1.5" beyond the vertex. OP calcs are similar.
Builders can do what they like, but I am going to be more inspired on the playa by an innovative cover and even more so by great creative people. than mixed pipe.
Some Seeing Eye, we used the Desert Domes Calculator too! I agree great tool!
My calcs came out a little different. But not by a ton. Also, I added a bit of cost to the Home Depot costs.
I work for a low voltage (telephone, MATV/SMATV, A/V, Broadcast cabling) contractor here in Denver. And I feel that, Home Depot has pretty competitive prices on EMT, with out having to fill out a credit app and set up an account, and buying in numbers under 1000'. Depending on where you are electrical suppliers may be willing to give whole sale rates with out tax IDs, credit apps, and smaller quantities. Our wholesale rates are about $38.85/1000' for 3/4" and $69.30/1000' for 1".
Are my calcs, with the weight and price marked up a bit from Home Depot. Though, I can't seem to figure out how to rotate that image. On my photobucket it shows it horizontal, but keeps loading it on here vertical, hum?
