         reinforcement can be conveniently placed in bed joints to reinforce walls in the horizontal
         direction.
         1. Deformed reinforcing wire conforms to ASTM A496/A496M-05: Specification for
           Steel Wire, Deformed, for Concrete Reinforcement [3.35].
         2. Welded wire fabric (WWF), which may consist of plain wire conforming to ASTM
           A185/A185M-06: Specification for Steel  Welded  Wire Reinforcement, Plain, for
