Children's Hospital Case Study - Utilities

Demolition of the Pennsylvania Hall and Civic Center in order to construct the Children's Hospital of the University of Pennsylvania (CHOP) expansion in downtown Philadelphia required driving piles to hold a retaining wall along Civic Center Boulevard and Riverview Drive. Numerous utilities and services were known to be located below ground in the area.

Construction Solutions was contracted to perform GPR surveys to locate services and utilities in and around the area where retaining walls need to be constructed. Locations and depths of piping and conduits were denoted on pavement and sidewalks as located. All located piping and conduits were documented via a drawing in plan view and by digital photographs.
