Substations pose unique geotechnical challenges. Foundations must be designed for transmission towers, sensitive electrical equipment and yard areas. AET must consider equipment support, settlement and frost heave movement tolerances of equipment, and large loads and over-turning moments on transmission towers. Soil resistivity is important for designing the grounding system.
Our Geotechnical Group provides an array of services for various utility companies and design engineers throughout the Upper Midwest for new substation design and upgrades of existing substations. Our Construction Services team performs necessary field observations and testing to ensure design standards and specifications are followed. Our Nondestructive Testing Group performs testing during fabrication and construction.
