BHI’s skilled field survey & inspection crews provide expert data that can be relied upon to streamline the design process and optimize construction time. Our use of drones, infrared thermography, ground penetrating radar, LIDAR and GIS system mapping, along with traditional survey techniques reduces revisions and changes in the field and provides more accurate field data for substantial cost savings.
BHI utilizes Drones flown by FAA certified pilots to provide more thorough data cost-effectively.
Ground Penetrating Radar (GPR) provides a safe, non-destructive and cost-efficient means of collecting underground utility data. With an understanding of the construction process and using certified technicians, BHI intelligently GPR-scans underground sites, marks strategic grid locations and avoids costly soft digs. GPR can locate the position and depth of metallic and non-metallic objects, up to 35 feet deep and with accuracy within 1-2 inches.
BHI uses Light Detection and Ranging (LIDAR) survey technology to rapidly analyze transmission and distribution lines, substations and other critical electrical infrastructure. LIDAR sends eye-safe laser light pulses that create millions of survey data points in high-resolution digital elevation models and 3D representations. As an example, LIDAR can be deployed as a tool in planning construction of new transmission and distribution lines as well as analysis of existing lines and substations.
With accuracy within 2-5 centimeters, and fast collection of 75 miles/day, LIDAR provides time- and cost-effective survey data that can be stored for future use and can save up to 50% over traditional survey methods.
Electrical equipment gets hot prior to failure, and identifying trouble spots early prevents failures and reduces the cost of maintenance and repairs. BHI provides reports on potential or emergent problems quickly and accurately using an infrared thermographer or drone, without using bucket trucks and full crews.
