Terracon's Charleston, W.V., office was established in 1980 as a branch office of H. C. Nutting Company (HCN). In 2007, HCN joined Terracon, after operating in Ohio, West Virginia, Kentucky, and Indiana since 1921. The Charleston office provides geotechnical engineering, drilling, environmental assessment, materials engineering and testing and inspection, and laboratory services. The Charleston, W.V., office has worked on projects such as bridge construction which included geotechnical investigations and materials consulting. Terracon has also consulted on site redevelopment for building construction projects.
The Blennerhassett Bridge is the final project in a decades-long effort to complete the four-lane Appalachian Corridor D from I-79 at Clarksburg into Ohio. HCN, a Terracon company, completed three geotechnical phases for the originally planned suspension bridge alternate. During the first phase, a preliminary geotechnical investigation was performed initially by drilling 21 test borings in November of 1999. A second geotechnical study was performed by drilling 34 borings in December of 2000. The second and third phases provided recommendations for the foundation alternatives at the towers,…
Adjacent to the existing school site, a new school development site was proposed. Terracon drilled seven standard penetration test borings as part of our geotechnical exploration. Based on the exploration, Terracon provided recommendations for two types of foundation systems. The foundations would be supported on the newly placed granular fill. This option had risk associated with it as uneven settlement across the footprint of the building could have occurred. The owner evaluated the options and chose the deep foundation system consisting of auger cast piles.
