Ground-Penetrating Radar (GPR) and Demolition

Ground-Penetrating Radar (GPR)

R. Baker & Son recently performed selective demolition at a renovation project at a pharmaceutical plant. One of the Baker Team’s challenges was to make way for new laboratory exhaust ductwork without cutting through or damaging utilities hidden within foot-thick concrete walls, floors, and ceilings or compromising structural integrity. As-built drawings are can often be inaccurate, especially in older buildings, so R. Baker & Son turned to ground-penetrating radar, or GPR, to reveal what was hidden in the concrete.  

GPR is a subsurface scanning method that emits high-frequency radio pulses into concrete or ground surface. When the radar waves encounter a buried object, they bounce back and are captured by a receiver that that processes and interprets the data and displays real-time screen images. GPR used in construction and demolition can reveal rebar, mesh, conduits, post-tension cable, and voids. An effective alternative to GPR is X-ray, which provides a far more accurate image than GPR but comes back with a number of significant drawbacks.  X-ray requires access to both sides of a slab or wall, is slower and more expensive than GPR, and generates harmful radiation that requires special precautions and procedures. 

On this particular demolition project, R. Baker & Son opted for ground-penetrating radar over X-ray due to budget and scheduling constraints. A GPR specialist was brought in to identify and mark out areas where there was little to no concealed electrical conduit and rebar before Baker crew members could proceed with cutting and drilling through concrete. In areas where it was impossible to avoid cutting conduit, GPR allowed the crew members to carefully chip away the concrete to expose the conduit and trace it back to its origin, where it was safely locked- and tagged-out. Other project work included selective demolition of lab casework, existing ductwork, and lighting.
