These were done as part of my work for Pathos-III, however the theme remains the same and can easily be applied to any genre of building. This was specifically requested to be under 100 parts which I can easily meet.
With designs like these, orientating the pipes may be difficult; I always offset this by including a connector part for every hallway type that allows the pipes to 'switch' sides on the wall/ceiling/floor to ensure the build doesn't look strange in a finalised plan.
