In your situation where you have a number of posts and you want the tops to all be level and you want to do all your checkouts on the ground before you concrete the posts in,pour a pad in the botto0m of each hole,around 100-150mm deep.When this has hardened off,set up your laser level in the center of your proposed carport. With your laser rotating,go to every hole with a piece of timber or a staff if you have one,and stand it in the hole,resting on the the pad you have poured in the bottom of the hole.When the laser comes around put a pencil mark on the piece of timber and mark it HOLE ONE. Do this to each hole,HOLE 2,HOLE 3 etc and you will know how much shorter or longer each post must be to to reach your level line that the laser is marking from the bottom of the hole.Measure up from this mark to your desired height.The mark that your laser is shooting is the datum.All your posts may have to be 1500mm above the datum or whatever is your chosen finished height,and now you know how long each post has to be BELOW the datum mark to reach the concrete pad.
