Im ready to start putting up the corner posts for my pole building. The area i have ready for the building is relatively flat, but not completly. I got it as close as i could. How can i get all of the corner posts to be the same height if the groundis uneven? I don't want to have my building be lopsided.
The way i would go about this is make the tops of your posts footings level and then you will not have to worrie about the posts length.
You could dig your post footings, pound some scrap 2x4's or something into the ground on the back sides of each hole, run string from 2x4 to 2x4 (creating a box) and get the string level. Then set the sonet-tubes so there tops just touch the bottom of the string and it should be nice and level.
Im sure others will have different or easier ways to go about this.
