Deck Above Grass
I am preparing to place a 10X10 deck above a grassy area. I will be placing 4X4's in a box like frame and go from there.
My question is: I have the lumber and cement mix to do the job, but the 4X4's are 12' and I need the 4X4's to be plumb and exactly square (10X10). How do I make sure this is completely sqaure.
By the way, The 4X4's are 12' high because it will act as a trellis as well (in the future).
Thanks for your help.

Ski: To ensure that the frame is square, measure opposite corners diagonally and compare that with the measurement of the other diagonally opposite corners. Both measurements should be the same. If they are, the frame is square. Good luck.
