Subject: [BUILDINGS] Standards (or Recommendations) for "Flatness" of Commerical Building Slab-On-Grade Floor

As I'm still trying to get a handle on specifying flatness--and so much
of the information seems to come from folks trying to sell their
equipment or processes--I was wondering if anyone had opinions on the
appropriate "flatness" criteria for a light commercial building?

Such a building would not necessarily have very high stacking or
shelving necessitating a "super flat" floor specification, but on the
other hand it's not like a residence. Many retail stores now "go bare"
on the floor finishes (I guess they like that "industrial" look like you
find in urban loft apartments, e.g.) and there are some high storage
considerations such as in the back room/stock room.

Has anyone dealt with this before?
