shit from the high altitude must be slowed down by some mechanisms,else it's like dropping a brick which will generate great momentum/impact to destroy the structure.
correct me if i'm wrong...

Well, every few floors or so we must add in an offset to the pipe to slow down the flow. I think it is every 30 meter got 1 offset. Usually for high rise buildings the sanitary stack at the bottom is Cast Iron Pipe 200mm diameter. Usually it is 200mm UPVC pipe (white in color). correct me if i'm wrong...

Withstanding the impact is one thing, in one project they even want to wrap it with acoustic wool to reduce noise in the pipe.
@ nicvoo,
What you say is soo true, there is a million pipes, cables, services running around the ceiling or floor that you are bound to knock into something.Mechanical services itself already have cold water pipes, sanitary pipes, fire-fighting pipes & cables, ACMV ducting, chilled water pipes (with insulation), BAS trunking etc.
For lift, one has to ensure all the lift manufacturers can masuk their lift into the shaft, otherwise the client will screw you coz you favor 1 supplier
