1.5 X 1.5 x 1.5 is a square (I should have used a cube, my bad) that I recommended you DO NOT do. If you want to use that much concrete go a meter by a meter, by 2 deep. Then you can walk close to the scope without walking on the isolated pier, and far stronger. I'm sure sheeny can explain the math, cause I sure as hell cant....
My concrete pad is only around 1/4m3 (compared to your plan of using 3.3m3)of concrete. It is a 300mm round hole down 1200mm slightly flared at the top and bottom. The secret is go deep. Sheeny was lucky that he hit bedrock, he effectively used the rock as an extension of his footing.
