MCI Garage Case Study - Post-Tension Cable

Upgrading the Kansas City International Airport parking garage facilities to incorporate new payment gates and automatic capacity counting system required extensive conduit installation. Several core drilled penetrations through the post -tensioned garage deck were required for these upgrades. Project requirements stipulated that existing services could not be disrupted and that post- tension cables and rebar could not be compromised or cut by the core drilling operations.

Construction Solutions was contracted to perform Ground Penetrating Radar analysis of the garage deck in order to locate all conduit, rebar and post-tension cables.

Because drilling was concentrated at the parking garage entrances and exits which had to remain open and functional, all GPR scanning was performed from the underside of the garage deck noting structure locations and depths directly onto the deck underside surface. Scan documentation consisted of digital photographs of each core drill location accompanied with a dimensioned drawing of each location noting all in slab structures.
