GAI Consultants uses advanced technology in applied mechanics to address the complex needs of the electric power industry. Blending academic training with research experience and practical engineering concepts, GAI provides a unique background for successfully solving complex problems in structural mechanics.

Proven capabilities in foundation analysis and design and 50 years of geotechnical experience means better solutions for reliable power delivery.

GAI’s structure modeling expertise has developed through many years of working with electric power clients providing consulting services for structure analyses and failure investigations. With a keen understanding of theoretical and experimental stress analysis theories combined with practical field experience, our engineers and technicians develop tower models for new design and conduct

investigations on existing structures and lines.

GAI’s foundation services for electric transmission are based on more than 50 years of geotechnical engineering experience. Geotechnical engineers and geologists conduct subsurface investigations, geologic assessments, subsidence evaluations and remediation, and detailed foundation testing, analysis, and design.

Over the years, GAI has amassed formidable experience in the full-scale load-testing of foundations, calibrating analytical models to the results of full-scale load tests, and developing computer programs for designing foundations efficiently. We conduct state-of-the-art studies and have prepared design manuals for clients on a variety of geotechnical topics.

With proven analysis and design capabilities, GAI also focuses on using detailed quality control procedures to monitor the construction of all types of structures and foundations. As a matter of routine, we perform pile, pier, or plate load-testing,
