Utilities
Utility Detection & Mapping
Using non-destructive technology to detect and record subsurface assets locations and depths. These surveys typically target buried architecture, water/sewer pipes, electrical lines, telecommunication cables, gas lines, and underground storage tanks (USTs).
Leak Detection/Pipe Inspection
Finding and examining underground spaces & materials impacted by the movement of fluids. Deliverables often include markings or maps that show where assets have been damaged, to informing repair operations, and assess asset health.
Multi-Channel GPR
Powerful technology to enhance GPR survey by multiplying the number of sensors employed during operation. These systems are designed to create much higher resolution imagery, which helps separate targets in congested environments & cover larger areas.
Earth Sciences
Archaeological Prospection
Mapping subsurface archaeological sites and sensitive cultural property with completely non-destructive technology. These surveys are commonly associated with Cultural Resource Management and the National Environmental Protection Act (NEPA).
Forensic & Cemetary Mapping
Surveys designed to collect evidence of anthropogenic activity & the deposition of materials into soil contexts. This can include cemeteries, clandestine burials, battlefields, & projects involved with the Native American Graves Protection & Repatriation Act.
Void & Sinkhole
Investigations designed to locate and examine the physical structure of subsurface void spaces and sinkholes at various stages of maturity, and in many environments. These features are often geological or hydrological in nature, or a result of decaying infrastructure.
Bathymetry
Measuring and modeling ground surfaces that are underwater. These non-destructive and cost effective surveys have become popular as a tool for tracking changes to waterways that result from natural disaters, development, natural geology. They have shown to be invaluable to both preservation and engineering.
Soil Contamination Studies
Tracking soil pollution across a landscape with minimal impact to active work sites and ecosystems. These surveys are well suited to providing detailed, accurate information for prevention and remediation. In many cases, geophysical exploration can provide depths and volumes of impacted areas, and asses their impact on ground water.
Infrastructure
Concrete Scanning
Examination of concrete, such as utilities, metal reinforcements, wall footings, grade beams, and support elements. Scans are performed to prevent utitility strikes and damages to structure during construction, repair, and modification projects. Used for design teams.
Concrete Testing
Concrete Testing and Inspection include investigations into the health and quality of concrete material itself. Typical targets are material hardness and slab thickness, along with rebar coverage, moisture and chemical infiltrations, delamination, and cold-joints.
Bridge Deck Inspection
Specialized concrete scanning and testing designed to examine bridgeworks specifically. Surveys are used to gather actionable information about the cause of damages, or at regular intervals to track health and degredation over time.
Road & Pavement
Non-destructive technology examine paved roadways & lots. Material thickness, drainage concerns, crack, sinkhole detection, & base material examination are all common targets of investigation. Some systems scan dozens of miles per day.
Dam & Levee
Specialized investigations for concerns common to these structures. Bigman Geophysical pioneered the use of robotics to conduct non-destructive testing over existing dams and spillways, and is well published for the results.
