can drains be installed after equipment
I need a reality check on a overzealous plumber.
1. Is it possible/advisable to install trench type floor drains in a cement slab after equipment is installed?
2. Are floor drains required for any license or inspections?
this depends on the type of slab beneth the equipment, if the slab isnt "floating" you may be able to, You should have an engineer have a look first, they can make a cut to check its thickness and ability to support the load of the equipment before you start to cut long slices from it. If you get it wrong the slab could resettle and you will have a problem.
As far as getting the main drain out it can be done with a bore, underneath the drain.
When we installed our brewery we thought we could just cut slices to set the drains but in the end we had to pour a 12" thick new pad above to inset the drains and get the correct slopes on the floors.
I wouldnt allow a plumber to make these decisions, Im sure they can put in the drain, but it may cause other problems.
you can do it but you'll have an inch of dust all over everything and in every teeny crevice imaginable in the brewery.
In addition to the dust, you will want to have the floor sloped toward the drain, for proper run off. The drains may not be required, but it would be tough to survive without drains.

I don't know about any legal issues with not having floor drains or proper floor sloping, but I have worked in breweries with these problems. From my experience, you might as well hire a full-time mop-man.
