Concrete expansion Bolts

I am having a concrete foundation poured on which I will install a prefab shed. It will be anchored to the concrete via expansion bolts. How long should I let the concrete cure before drilling?

28 days is the norm for allowing concrete to cure

Why not set concrete anchor bolts into the wet concrete?

Anchor Bolts

Why not set them in wet concrete, I cannot be that precise as to where they should go.

Should I use expansion bolts or concrete screws, which is best?
