The Program: During expansion of a casino entertainment complex in Atlantic City in 2003, a portion of the parking garage collapsed, causing numerous construction worker fatalities and injuries. Garage construction consisted of stay-in-place, precast, prestressed concrete formwork and cast-in-place composite floor system connected with mild steel reinforcing to cast-in-place concrete columns and shear walls. The collapse occurred during placement of floor concrete at an upper level, leading to progressive failure of multiple levels. Various methods of investigation and analysis were used to assess the cause of the failure. Results of this investigation and recommendations on how to avoid such accidents in the future will be presented.

Gene Corley serves as CTL Group’s managing agent for professional and structural engineering, and leads structural evaluation projects related to industrial, transportation facilities, parking facilities, bridges, and buildings. His wide range of experience includes evaluation of earthquake- and blast-damaged buildings and bridges; investigation of distress in prestressed concrete structures; repair of parking garages damaged by corrosion; evaluation and repair of high-rise buildings, stadiums, silos, and bridges; design and construction of repairs for prestressed and conventionally reinforced, precast and cast-in-place concrete, and structural steel facilities and foundations.
