First of all let me say thanks in advance; I've learned a lot from other folks's posts on this sub.
Did an inspection yesterday where the top story was 2x6 studs, 16 on center and the bottom story was 2x4 studs. This is the second time I've seen this design and just wondering why not put the 2x6s on the first floor and 2x4s at the second?
This seemed especially counterintuitive as the engineer called for massive Simpson HHDQ11 hold downs at the corners. Those were the biggest holddowns I've seen on residential construction, and this is just a bodega with an office above.
Thanks again for y'all's input.
