Value added, from concepts to completion

Our professionals can partner with you to clear the hurdles needed to make your electrical transmission line project a reality. The linear nature of transmission lines can bring different environmental factors into play. Terracon’s siting and routing services can quickly help identify the optimal path. Our environmental professionals can then advise on local, state, and federal planning and permitting regulations – anticipating challenges and providing reliable timelines to keep projects on schedule.

Terracon’s geophysical surveys provide rapid, safe data acquisition with minimal site disturbance, offering a major advantage over traditional methods. Using non-intrusive techniques alongside intrusive methods, we deliver enhanced site characterization and valuable subsurface information — even in remote areas — while reducing the risk of unexpected conditions.

Efficiency at every step

Armed with subsurface data, we develop the geotechnical site evaluation needed to build an economical design solution. Additionally, we perform modeling of soil and rock mechanics and collaborate with structural and construction professionals to identify appropriate construction techniques for specific site conditions.

We’re ready to assist when construction starts, too. Our design, inspection, and materials testing services are all under one roof. Tower foundations and substation sites can be optimized and streamlined, while accurate inspection and laboratory testing data is delivered quickly, without the need to subcontract those services to a third party. With one of the nation’s largest networks of accredited and approved laboratories, we deliver the fast, accurate data needed to verify the performance of construction materials. From asphalt, concrete, and soil to aggregates, we make sure materials perform as intended.

No matter the location of your next project, Terracon’s footprint of more than 200 offices across the country means the equipment, expertise, and resources you need are never far away.

From the early planning stages required for a range of geotechnical explorations on public and private lands (including public land approval and environmental requirements) to the execution of the tasks and final documentation, Terracon staff have been professional and provided high-quality services.
