Inspection Pit 4 was installed as part of the original building construction in 1980. The structural steel of the drive lane of Pit 4 has pulled away from the concrete stem wall and has been shored up twice in past projects. Currently, the concrete stem wall that supports the structural steel and also acts as a retention wall for Pit 4 shows signs of failure. The design for repair of inspection Pit 4 was conducted by the design team of S.E.H. The repairs in this project include removing all utilities from Pit 4, removing any remaining structural steel, cutting the concrete stem walls to 16” below finish grade, installing reinforcement that ties the stem wall to the structural deck, placing new concrete, then installing all structural steel and utilities.
