It is such a minimal intrusion I don't even design for it when I design a
foundation. Really the outside edges of the concrete and the embedded steel
carry almost all of the load from a tower so the center portion of a
foundation doesnt matter. In fact my tower foundation is only thick enough
to cover the top and bottom steel reinforcement in the center. I have seen
guys use 4" sewer pipe for their tower conduit with no problems.
