@rasaNova, the dirt was raised and even with the bottom of the flooring I put down. I couldnt tell you how many were actually foundation pieces. as far as the posts that never occurred to me. they were most likely on the floor.

@weaver stories I am refering too is a full length core wood post. (think its the 4x4). and thank you for the video. I knew about the support system but didnt know about the foundation pieces (the blue ones). So thank you!
