I've received a structural engineer report where the engineer has defined the dimensions of the required padding. It's the padding that a steel column post will be bolted into. I noticed he's put some spec for concrete reinforcement using rebar. I'm just wondering, from the design below how do I understand the required rebar needed?
The only thing I can understand is that U-Bars are required but can I not use the ordinary mesh cages that is normally used for reinforcing concrete?
