Beginnings

A partial view of the first steps to the pool install.  There are 10 of these blocks, each set about 3" below eventual finished grade and all are level and level with each other.  I am a little under 1/4" out across the 20' width of the pool, which isn't bad.  This was the worst spot.  There are 3 blocks in that pic spanning 84". I had to excavate an area about 2' wide by 84" long 4" or so down so I could start leveling the blocks.
