Services - GSI Engineering: A Division of Alt & Witzig Engineering (formerly Geotechnical Services, Inc.)

Get the Job Done Right

What is under a piece of property can be just as important as what is on it. This is especially important when construction is being considered or when there may be contamination of soil or ground water. Properly performed geotechnical engineering characterizes the properties of earth materials and predicts the reaction to loading conditions, resulting in improved foundation design, fast-track construction time, lower costs, reduced delays and increased awareness of environmental risks.

For nearly four decades, GSI (formerly Geotechnical Services, Inc.) has been recognized as a leading expert in the geotechnical engineering field. We maintain a large fleet of subsurface exploration equipment. Our in-house drilling enables us to offer time-efficient scheduling and the ability to mobilize the appropriate equipment and crew within hours.

Innovative Solutions Experienced and safety-trained personnel, superior equipment, geotechnical and environmental expertise, and project management capabilities are combined to form a professional and cost effective drilling division.

In House Certified Laboratories provide specialized services for inspection sampling, testing, and documentation, as well as Quality Assurance/Quality Control activities to determine physical properties of soils for construction materials and geotechnical projects..

Protecting Your Investments Protect yourself by performing Phase I, II and III Environmental Site Assessments (ESAs). Since landowners can be held financially responsible for contamination on their property, an ESA can help real estate purchaser and lenders minimize environmental liability by revealing past, current, and potential environmental issues.

Chemical Releases - What should you do when they occur?

Unfortunately, chemical releases can occur despite your best efforts. GSI can conduct release investigations to determine the extent to contamination, whether at a petroleum, solvent, agricultural or other industrial site.
