Nicky, I have seen some seismically designed structures in Southern California use very large Metraflex FireLoop type connectors where the underground services come into the building. This one building in particular was designed for the ability to move about 4 feet laterally in a seismic event.
I am not sure if your building is designed to move but this type of flexible FireLoop could potentially help you meet your design objective.
