Geophysical

BSK Associates provides geophysical services that help clients better understand subsurface conditions while minimizing disruption to active project sites. Using non-invasive technologies, our team collects high-quality subsurface data that supports informed engineering, environmental, and construction decisions. Whether identifying buried utilities and infrastructure before excavation, evaluating unknown subsurface features (e.g. underground storage tanks, landfills, drums, wells, etc.), or supplementing geotechnical investigations, our geophysical services improve project planning, reduce uncertainty, and help manage risk.

Our geophysicists work closely with geotechnical engineers, environmental professionals, surveyors, and project teams to develop practical solutions tailored to each project’s objectives. By integrating geophysical methods with traditional field investigations, we provide a more complete understanding of site conditions while often reducing the amount of invasive exploration required.

Geophysical Investigations

Geophysical investigations offer an efficient means of evaluating subsurface conditions across large areas while minimizing impacts to existing infrastructure and site operations. BSK utilizes a variety of proven geophysical methods to characterize subsurface conditions, locate buried features, evaluate geologic conditions, and support engineering and environmental investigations.

Our services support a wide range of applications, including:

• Geotechnical site characterization
• Bedrock depth and rippability evaluations
• Void, anomaly, and buried object detection
• Landfill investigations
• Environmental site characterization
• Underground storage tank investigations
• Pavement and infrastructure evaluations
• Groundwater and geologic investigations
• Subsurface mapping for design and construction planning

Depending on project needs, our team employs technologies such as Ground Penetrating Radar (GPR), Electromagnetic (EM) surveys, Electrical Resistivity Imaging (ERI), Seismic Refraction, Multichannel Analysis of Surface Waves (MASW), and other specialized geophysical techniques. We select the most appropriate methods based on site conditions and project objectives to deliver reliable, actionable results.

Private Utility Locating

Underground utilities represent one of the greatest sources of risk during construction and subsurface exploration. BSK’s private utility locating services help owners, engineers, contractors, and developers identify and map privately owned underground utilities before excavation begins.

Our utility investigations on both private and public property help reduce utility strikes, improve worker safety, minimize costly delays, and support regulatory compliance. The utility location on public property is also used in design engineering.

Our utility locating services include:

• Utility locating and mapping
• Utility corridor investigations
• Pre-design utility engineering support
• Utility verification for construction planning
• Subsurface Utility Engineering (SUE) support
• Ground Penetrating Radar investigations
• Electromagnetic utility locating

By combining utility locating with our broader geophysical capabilities, BSK provides clients with a comprehensive understanding of subsurface conditions before construction or drilling activities begin.

Integrated Solutions

One of BSK’s greatest strengths is the ability to integrate geophysical surveys with our geotechnical engineering, environmental consulting, construction materials testing, and laboratory services. This multidisciplinary approach allows our clients to work with a single trusted partner throughout the life of a project while receiving coordinated recommendations based on a comprehensive understanding of site conditions.

Whether supporting transportation, public infrastructure, education, healthcare, commercial development, industrial facilities, renewable energy, or environmental remediation projects, BSK delivers practical geophysical solutions that improve decision-making, enhance safety, and reduce project risk.
