Children’s Hospital of Philadelphia Plaza
The Children’s Hospital of Philadelphia (CHOP) Plaza encompasses the entrance area at the front of the Wood Center building. Water was infiltrating the Plaza, requiring repairs to preserve the structure.
The Wood Center building is connected to the main inpatient facilities and provides specialized care and imaging services.
Water was penetrating the grade plaza level through the ceiling of the Wood Center parking garage causing the deterioration of the concrete structural elements.
PULLMAN was contracted to address the water infiltration and preserve the below-grade garage structure. The team was brought on during phase 4 of a multiple-phase project. The scope of work included removing and replacing brick paving systems, concrete curbs, asphalt road, and stamp concrete walkways. The team also had to replace the waterproofing system, drainage layers, add an expansion joint assembly, and install a new topping slab.
One challenge the team faced was the site location was isolated to the sidewalk areas adjacent to the drive lanes. The drive lanes remained open to the public to maintain traffic flow for the duration of the project. In order to mitigate the issues, the team placed multiple safety barriers to separate the work zone from the drive lane.
The project was safely completed on time.
