Howard -
Regarding the discovery of a storm drain pipe at the location of a proposed footing
for the new patio cover, I make the following recommendations for resolution based
on the owner deciding not to relocate the pipe
1. Provide a minimum 6" diameter schedule 40 pipe, cut in half lengthwise over
the top of the existing pipe and extending a minimum of 3" outside the
formwork for the footing; fill gap between drain pipe and covering pipe at
each end with compressable neoprene.
2. Provide#4 rebar over and perpendicular to the pipe with 2" clearance at 6"
on center.
3. Footing to be increased in plan dimension by 6" each side of pipe.
4. Hold schedule 40 pipe in place with rebar driven 8" minimum into the ground
at 45 degree angles each side at 12" on center.
5. When depositing concrete, do not place on top of pipe until both sides are
placed.
