Is it possible that an above-grade structure could support your tower?
Consider gathering up your tower specifications, antenna load data, any
available engineering data from the tower manufacturer, manufacturer's
technical contact information, your below-grade structural design, and
anything else pertinent. Visit a local structural engineer and ask if he
can do a preliminary feasibility analysis for an above-grade structure, and
provide a proposal for a full design if one is feasible. Would probably
cost you a few hours of his labor at most for the preliminary look.
Judicious use of engineering talent can be a money saver!
