Why do you need a 4" UG for 13R? We do them on 2 and 2-1/2" UG's all the time, including combined services with a domestic allowance taken for fixture count at the common supply point. Is this to be a dedicated 2" fire service or a combined line?

The mech. consultant specified 13D. I recommended 13 or at least 13R. They settled for 13R. But by this time a 2" underground was already installed. They wouldn't give me the 4" underground I needed for designing to 13R. Finally it was designed to 13D for a two head calc and agreed (at my insistence) to provide a pump for a 4 head calc. I can't believe they had money for providing a CO2 system for the elect. room but refused to upgrade the system to 13R.

It doesn't seem that 13D would be appropriate for the structure, but I don't see anything in any of my Codes that would modify it. Todd G.
