The slab pour you outlined is sometimes referrred to as a "mono pour" meaning all concrete for footers, piers(supports for vertical loads and weight bearing equiptment) and the final finish floor slab are all poured in one continuous pour--a very effective way to ensure less slab movement--Caveat BIG IF the reinforceing ie rebar, steel wire mesh are properly installed --this is where you really need a good concrete contractor familiar with commercial installation as this is where this system is usually used--also you need to have the slab IMO about 6" thick, especially over a sand base and have stress grooves in the concrete closer than in a normal slab to help deter/reduce slab cracking--common in concrete garage floors. Don't know of any concrete contractor that will guarantee his slab won't crack

Since you'll be building over a sand base you may want to consult with a soil engineer--only advice I can give is if you have a high water table you may want to think of installing a "french drain" system under the foundation to wick water away -- and always use the best vapor barrier available directly under the slab.

As for a final working finish--Race Deck--pricy but oh so "pro-shop" looking--a good, quality 2-part epoxy finish is equally a solution and properly applied will withstand years of abuse--and less expensive--this would have to be your choice of what you want your shop floor to appear in final form.

Good luck--and have fun--keep the stress level under control--something a lot of people entering a building project lose sight of
hope this helps
