Can someone help with the answers/hints? Thanks!

1. Can we run normal and emergency power conduits in same trench? If we can, do we maintain min. distance between normal and emergency conduits?

2. Do normal and emergency power conduits required to be in a separate duct bank?

3. Can we run electrical conduits and mechanical pipes in same trench, do they need separation?

Nec only specifies separate conduits or raceways, no need to separate any farther than that and as far as with mechanical systems i would ask both sets of inspectors.
