Very excellent build.  The instructions were very well laid out.  There were only a couple of times that I had to really had to scratch my head to figure it out.  Most of the build I performed by myself until I could get help to put large sections together.  The pre drilled holes were laid out very well.  The only exception was that the purlins like the T02 on the top of the left and right roof panels had the holes set up on the center of rafter which puts the screw right into the bolt for the rafter.  I appreciate the protection on the metal roof panels but if I never see another piece of blue plastic it will be too soon!
