Generally high voltage ( electrical ) and low voltage ( network) should be in physically seperate conduit. This is both for safety (heat as well as cable breaks) and for actual noise issues. This is something that should be done by an engineering firm no an architect, the architect should know it needs to be contracted out though. Most property just isn't built to those kinds of margins.
