Here the rebar is constructed in the beams of the foundation for support, along with a "carpet" of mesh along the top.  Note the extra large beams,
engineered to withstand any flex from the soil resulting from severe drought or heavy rains / flood conditions (the worst threat).  Next will come the
electrical wiring to be placed within the foundation, and final checks on form dimensions and stability prior to pouring the concrete.
