i would add to your budget a proper top coat for the concrete.
https://usa.sika.com/en/construction/floor-wall/flooring-systems/sika-ucrete.html is the golden standard IMO. but you could also lay heavy tile or at the BARE minimum several heavy coats of epoxy.
proper CIP chemicals will make quick work of bare concrete... they will eat holes into it exactly where the chemicals drip out of the tank onto the floor and they will QUICKLY eat your trench drain if it is not lined with SS or atleast PVC or epoxy.
it is also important to consider the temperature of your waste water. Generally you are running your cip at >140f for caustic and your knockout will be very hot. if your pipes are just basic schedule 40 pvc(in the us this is normal) they will get very soft at those temps. glue joints very quickly fail and your chemicals will then have access to everything and will eat a hole. could also undermine the building if it is bad enough. i am not saying that you need SS pipes, but you need to be aware of the plumbing you are dealing with.
Also i love Uerige! i may or may not have stolen one or two of their glasses 15 years ago....
