GSSI updates BridgeScan bridge condition assessment system for concrete inspection and utility mappingEngineering Ground penetrating radar
The ground penetrating radar equipment is tailored for bridge condition assessment, accurately representing bridge data by automatically accommodating for bridge skew angle.
GSSI, manufacturer of ground penetrating radar (GPR) equipment, has announced an updated version of its BridgeScan, a flexible GPR system for assessing concrete condition on bridge decks, parking structures, and balconies. Accurately determining concrete condition improves repair cost estimation, saving time and money.
With BridgeScan, identification of rebar location and depth is easy and quick, making it well suited for bridge deck condition assessments, determining concrete cover depth on new structures, and concrete inspection, as well as measuring slab thickness, and void detection and location. Engineers can also use the unit as a basis for a utility locating GPR system to map and locate underground infrastructure – pinpointing the depth and position of metallic and non-metallic pipes in real time.
Unlike other systems, BridgeScan is tailored for bridge condition assessment, accurately representing bridge data by automatically accommodating for bridge skew angle. Using a non-destructive method of evaluating bridge deck thickness, the BridgeScan system can obtain thickness measurements in minutes, eliminating the need to core.
Updates to the BridgeScan system include the SIR 4000 data acquisition system, designed for single-user operation, which incorporates advanced signal processing and display capability for ‘in-the-field’ 3D imaging. The unit features an enhanced 10.4-inch LED display and on-screen post-processing. The SIR 4000 control unit can be used for multiple applications.
The new BridgeScan features a self-contained cart-based design, and also includes a 1600 MHz antenna, a survey cart with encoder wheel, 2 meter control cable, and 2 batteries with battery charger, as well as a custom transit case for the control unit, AC adapter, and a sunshade. The system’s cart design and integration with GPS makes it intuitive and easy to use. BridgeScan comes with a 2-year warranty.
