Hi Charles,
With a thick enough base flange (I am using 10mm thick steel plate 300x300mm square) I don't believe you will require any spacing between the base flange and the slab.
I'm sure other members will provide some advice on this.
I came across this website:

There is a small section at the bottom of the page for piers. One thing I did notice that Sonotube is more popular in the USA than here.
