Repair and Rehabilitation Design

Adam Clayton Powell State Office Building, Bronx, NY

   Water leaks through the plaza pavement and the planter boxes caused extensive damage to the parking garage  below.  The reinforced concrete parking structure suffered  extensive damage consisting of concrete spalls, cracks, and corrosion of the reinforcing steel.  FKC performed an investigation to identify the water leak sources, and to determine the extent of damage.  An engineering report with findings, conclusions and recommendations was issued.  FKC  prepared repair drawings and specifications, and performed construction administration services.

Summit Plaza, Newark Avenue, Jersey City, NJ

 The one-way joist reinforced concrete parking structure, exhibited extensive deterioration as a result of corrosion of the reinforcing steel.  Additionally, the end columns of this very long structure suffered extensive damage due to the thermal movements of the plaza level.   FKC investigated the structural damage and designed repair details and specifications.  New end columns were designed with sliding slab supports in order to accommodate for the slab thermal movements. 

Marcus Ave., Lake Success, NY

The expansion joints at the plaza  level of this office complex exhibited extensive deterioration in a relatively short time (about five years) after construction.  FKC investigated the causes for the premature expansion joint failure and issued a report on the findings, conclusions, and recommendations.  FKC designed repair details, prepared design drawings and specifications, and performed construction administration services.

Due to the expansion joint failure and water penetration, the metal deck and slab had deteriorated and several supporting steel beams had extensively corroded.  FKC used ultrasonic testing to determine the extent of beam corrosion, and evaluated the loss of beam strength.
