GAI Consultants is exceptional in helping clients manage the ground materials and geologic processes that affect their facilities, properties, and project sites. Our geotechnical engineers and geologists are highly experienced in the basic principles of engineering geology, soil and rock mechanics, foundation engineering, subsidence, and mine studies. With years of academic training, and extensive research, and field experience, GAI’s depth of experience and knowledge represents a viable and valuable solution for unforeseen foundation issues.

A reputable source of professional consultants skilled in engineering geology, soil and rock mechanics, foundation engineering and subsidence means better long-term solutions.

Thorough site explorations detect geologic and environmental hazards that can disrupt site or

project development. GAI’s geotechnical expertise in site design includes addressing areas subject to expansive materials, sinkholes, and subsidence such as those underlain by karst and underground coal and limestone mines. GAI also has extensive site design experience in areas of potential seismic activity and those with liquefaction potential.

For many projects, soil is a finite and critical resource. GAI moves projects forward by evaluating subsurface and soil conditions, and recommending effective use of available soils. Knowing that projects require large amounts of soil and unconsolidated rock material, we help clients plan excavation sequences, processing needs, and optimum soil placement.

GAI’s broad range of services includes feasibility studies that identify contaminated soils. We evaluate chemical, biological, hydrological, and regulatory factors, and recommend acceptable, cost-effective monitoring and remediation solutions that meet regulatory requirements. Our plans to

re-establish permanent vegetation cover on disturbed lands and contaminated sites includes customized fertility programs and seeding mixtures, and we specialize in using coal combustion residuals to expand limited soil resources.

Soil is an excellent medium for re-using wastewater for farmland irrigation, and GAI’s innovative design technologies include developing and implementing wastewater spray systems for vegetative fields. These systems evapotranspirate wastewater and organic contaminants are biodegraded into the topsoil.

Covering the entire expanse of geotechnical engineering, geology and soil science, GAI remains a reputable source of professional consulting. We address the myriad of soil, rock, and foundation factors that affect existing features and future land use.
