1. All pipe is to be made of a long hole ,surrounded by plastic centered around the hole.
2. All pipe is to be hollow throughout the entire length of the pipe- do not use holes of different lengths.
3. The inside diameter of all pipe must not exceed the outside diameter otherwise the hole will be on the outside.
4. All pipe is to be supplied with nothing in the hole so that cables / liquid and other stuff can be put in at a later date.
5. All pipe over 150 metres should have the words " LONG PIPE " clearly painted on each end so the gangs will know it is a long pipe.
6. All pipe over three killometres long must also have the words "LONG Pipe " painted in the middle so the gang will not have to walk the entire length of the pipe to detirmine if it isa a long or short pipe.
7. All pipes over 100mm diameter must have the words " LARGE PIPE" painted on it so the gang will not mistake it for a small pipe.
8. When ordering 90 degree, 45 degree or 30 degree elbows, be sure to specify right hand or left hand bends otherwise you will end up going in the wrong direction.
9. Be sure to specify wether you want level, uphill or downhill pipe. If you use downhill pipe for going uphill, the cable / liquid will flow in the wrong direction.

Alas I can't lay claim to this logic. Author lost in time.
