Hi Paul!


First, you need to be aware of the CONTEXT of this VE suggestion. Would the VE option mean no acids could be thrown down any other than the five designated drains? Do you know how many total drains there are and can the use of these drains be predicted reliably at this time? Is the originally designed piping for acid waste a dedicated drain system or does the design use one drain system to handle all liquid waste?


The under counter acid neutralization “tanks” mentioned are very small and need frequent “refills” of (usually) crushed lime.  If the traps are located under fume hoods, they are usually difficult to get to.


Also see if the acid waste piping quoted was Pyrex glass. Years ago this was the only option and it was expensive. There are other options available now.

Good morning,


We are currently in the planning process for a College of Osteopathic Medicine. We were just sent a question in regards to some of the plumbing for the building, and I wanted to get some of your  opinions.


“We are in the midst of finalizing the pricing with the contractor on the COM and they have offered a value engineering option I would like to get you feedback on. Please advise if this is an acceptable option.
