The Pentagon, Washington DC
A Ground Penetrating Radar (GPR) investigation was performed at a ramp at the Pentagon Mall, Washington DC
The procedure was done in 3 phases – (i) Investigation of the road surface using a 900 MHz antenna, (ii) Investigation of two 6’x6’ surfaces at the top & bottom of ramp using a 1600 MHz antenna, and (iii) Investigation of the ceiling / beam from the underside of ramp using a 1600 MHz antenna.
CCBC - Catonsville, Maryland
A Ground Penetrating Radar (GPR) investigation was performed at the loading dock area by Building K at CCBC, Catonsville, Maryland.
The procedure was done in 2 phases – (i) GPR Investigation of the road surface using a 900 MHz antenna, (ii) EMF Induction investigation of the road surface with targets marked.
8045 Kennett Ave, Maryland
An extensive study of the sub-surface elements in the concrete slab and beam were conducted at the test site with post processed radar images.
By using GPR practitioners can identify where rebar and other embedded objects are within the concrete decks and beams, locate safe and unsafe drilling areas, and can use the resulting 3D map to document the embedded objects for future retrofit or rehabilitation of the concrete decks & beams.
Camden NoMa, Washington DC
A 1600 MHz antenna was used to collect the data scanning to an approximate depth/height of 18 inches for future slab penetrations at Camden NoMa.
A total of 3 locations were scanned using 3D GPR methods with 2'x2' and 1’x1’ grids. All targets were marked on the concrete slab with permanent markers as shown in the photographed site conditions. The corresponding 3D grid images are shown as well.
