It always seems to take us more time to do things than we think it should. However, squaring up your structure is one of the most important steps so going too fast through this process won't gain any time, only headaches. Needless to say, do it right before moving forward.
Two pallets of concrete and 2"x 6" fir boards for the base and hip boards. Felt good to support our local lumber yard. The trailer was sure weighted down.
A 9" auger made short work out of the 32 holes that needed to be dug.
We had the help of our two girls yet again. They marked each ground post at the appropriate spot to ensure there would be 6" of pipe sticking out of the ground. Then they placed them next to each hole for easy installation.
Since the structure is so tall (and the manufacturer requires it) we added concrete to each post. Oh pile of concrete bags...
