I am currently building a 30 x 48 with 12 foot tall walls metal sheeted building. There is also a wrap around small porch on the front, two 30 50 windows, and two 30 00 doors and two 9x9 foot garage doors. There is a 30 x12 foot gravel lean too on the back.
The footers for the concrete pad and stem wall are curing now. They were poured on Friday. I plan on the exterior walls being 2x6 framed on 24 inch centers. I am using trusses for the roof. I have an Amish crew that is going to do the framing and metal sheeting. I planned on the trusses being on 2 foot centers. They said that for my area, I could save a bunch on money by doing 4 foot centers on my trusses since they are engineered trusses.
We dont get alot of snow here in Lebanon, MO (SW Missouri) but, I dont want the roof caving in either. What will I loose by going to 4 foot centered trusses? Will I be less resistant to high winds or snow load? Or is 4 foot common now and I am over building???
