BuickFarmer, we had 2, 12 foot ladders and we carried the trusses up and set them on the truss carrier, this building is close to one i saw in Michigan, here in the texas panhandle we do occasionally(Feb2013) get 20 inches of snow, and the wind blows hard here, its actualy worse than chicago, we carried them up in the upright position too, we tried upside down on the first truss and it just seemed easier to carry it up ,right side up. i spent 3k on concrete, and 800 on finish work, so 3800 plus 600 for rebar and wire mesh 4400 of the 12k.the rebar was 16" on center, 1/2 inch rebar, the edge of the slab is 6 inches thick, the rest is 4 inches, i used mesh on the drive way, i was less worried about it, i started this project on august 1st 2012, i had the majority of it finished by spring break, (mid march) it took me a while to save up for the drive way, one reason it took me so long was i paid for everything as i went, i think i ended up with 2k in credit card charges for the whole project and thats on a citi bank simplicity card with 0% for 18 months.
