The Trans Alaskan Pipeline runs from the north to the south in a pipe that is above ground.
You need a welder the flex pipe part and a saw and a car lift.
You use a welder, not jumper cables!
The pipe must be fixed (not rolled) in the horizontal position. With the pipe horizontal, the weld is vertical.

With the pipe horizontal, the weld is vertical. The pipe being fixed requires the welder to weld flat (top), vertical (sides), and overhead (bottom).
Given one invert, and the length of the pipe and the slope of the pipe, you multiply the the length of the pipe by it's slope (expressed as a decimal ratio) and add the result to the known invert.
For proper fall. Pipe should slope 1" for every 8'.
