new shop build

I couldn't find any plans like I wanted so had to draw it myself and then get a kid that did drafting to put it to scale. The overall diminsions are 36 wide by 40 deep. Since it is so close to my house I wanted the roof and trim to match. The roof is 12/12 pitch then dropping to 5/12. I was trying to get my height for a lift in center bay so that is reason for having my trusses built like a tray ceiling. I dug trenches with backhoe where the lift will go for extra support and footer all the way around and deeper in front of doors. Poured the slab then had blocked laid three blocks high. In the slab I put J bolts for anchors then put couplings on them and cut all thread rod long enough to bolt pressure treated 2"X8" plate on top of blocks. I poured the cells in blocks with concrete when I poured front apron to connect my existing driveway before starting with wood. So my wood is attached directly into the slab. More photos.
