Vertical shaft reinforcement features type 1 mechanical splices, staggered at four feet typically, and terminates above at least a single layer of the mat foundation or pile cap reinforcement. Additional vertical reinforcement and ties are provided per the typical drilled shaft schedule, alongside a temporary steel casing as required by the geotechnical engineer. Backfill is installed per the contractor's specifications.
