1. Pipe compaction limits shown on this plan are for pipe
construction in an embankment. For pipe construction
in a trench, the horizontal limits of the pipe compaction
zone shall be the walls of the trench.

installed in accordance with design A.
3. Concrete pipe with elliptical reinforcement shall be
installed in accordance with design A.
4. Concrete pipe, plain or with circular reinforcement, shall
be installed with design A.
5. D.D. Is equal to the outside diameter of a pipe or the
outside span of pipe -arch. The dimensions shown as
O.D. with T maximum shall be O.D. until O.D. equals
3'; at which point 3' shall be used.
* 1'-0" for diameters 12" through 42" and spans through
50". 2'-0" for diameters greater than 42" and spans
