Procurement of RABIT™ Bridge Deck Assessment Tools

Procurement of RABIT™ Bridge Deck Assessment Tools

Through Pennoni’s Performance Management of Bridges IDIQ contract with Federal Highway Administration (FHWA), Intelligent Infrastructure Systems is working with Infratek Solutions Inc. to design and build the commercial version of the RABIT™ Bridge Deck Assessment Tool.

Intelligent Infrastructure Systems and Infratek are providing the services necessary to manufacture, calibrate, validate, prepare operations documentation and deliver maintenance and warranty services for four (4) RABIT™ Bridge Deck Assessment Tools. This includes providing expertise in determining Nondestructive Evaluation (NDE) sensor payload on the robotic platform, automation of NDE data collection, analysis, postprocessing, visualization leading to condition evaluation of bride decks and using navigation of the robotic system to spatially locate and stitch NDE data and images. We are also providing technical support and training for Long-Term Bridge Performance (LTBP) program field personnel on the proper deployment, operation, and maintenance of the systems.

RABIT™ is a robotic nondestructive evaluation (NDE) platform designed to enhance the assessment of bridge decks and was developed as part of the Federal Highway Administration (FHWA) Long-Term Bridge Performance (LTBP) program. RABIT™ includes high resolution cameras and imaging systems, Electrical Resistivity to characterize the corrosive environment of concrete, Impact Echo and Ultrasonic Surface Waves to evaluate concrete delamination and concrete deck strength, Ground Penetrating Radar to map rebar and other metallic objects below the surface, and a Global Positioning System to record and mark location data.
