GROUND PENETRATING RADAR (GPR) SURVEY SPECIALIST

Ground Penetrating Radar (GPR) survey is a non-destructive geophysical method used to investigate and map the subsurface of the earth. It uses high-frequency electromagnetic waves to detect objects, structures, or changes in material beneath the ground surface. The GPR system sends signals into the ground, and when these signals encounter different materials or objects, they bounce back to the surface, where they are recorded and analyzed. 

Subsurface Utility Engineering (SUE) Survey is a highly specialized process used to accurately locate, identify, and map underground utilities. It involves the use of various advanced technologies, including Ground Penetrating Radar (GPR), electromagnetic induction, and vacuum excavation, to safely and precisely detect utilities like water pipes, gas lines, electrical cables, and sewer systems beneath the ground. The primary goal of SUe surveys is to reduce the risks associated with construction projects by preventing utility strikes and minimizing disruption to services. 

Topographic Survey is a detailed survey that maps the contours and features of the land's surface, including natural elements like hills, valleys, trees, rivers, and man-made features such as buildings, roads, fences, and utility lines. The goal of a topographic survey is to create an accurate representation of the land's surface, which is crucial for planning, design, and construction projects. 

Cable/Pipeline Locating Survey is a specialized survey used to identify the precise location, depth, and routing of underground cables and pipelines. These surveys are crucial for construction, maintenance, or repair projects that involve working around or near existing underground infrastructure, such as water, gas, electric, and communication lines. 

 Seismic Refraction Tomography (SRT) Survey is a geophysical method used to map subsurface properties, particularly in relation to the speed of seismic waves passing through different materials. This technique is based on the principle of seismic refraction, where seismic waves are refracted (bent) when they encounter layers of materials with different seismic velocities. By measuring the time it takes for these waves to travel through the ground and analyzing how they refract, an SRT survey can provide detailed information about the subsurface structure, including material composition, depth to bedrock, and soil conditions. 

Electrical Resistivity Tomography (ERT) survey is a geophysical method used to map subsurface features based on the variation in electrical resistivity of materials in the ground. It is a powerful tool for imaging the subsurface in 2D or 3D and provides detailed information about the type, structure, and distribution of subsurface materials like soil, rock, groundwater, and contaminants. ERT surveys are commonly used in environmental, geotechnical, and water resource investigations.
