Solar

Investment and proprietary innovations in test pile installation and pile load testing data collection provide clients with the timely, accurate data needed to make informed project decisions. Our team of owned and operated piledrivers dedicated to solar clients eliminates the expense and wait for subcontractors. No matter where your project is located in the continental U.S., we can dispatch a test piledriver to collect the data needed to keep the project on-schedule.

Pile Driving

Environmental

Environmental regulations can be intimidating at first glance. Our environmental planning experts bring clients local- and state-level experience, as well as access to our nationwide services, to guide you through every step of environmental compliance and help keep power generation projects on track while minimizing impacts to nearby natural habitats.

Transmission line

Our network of experts across the country can perform the spectrum of services necessary for siting, permitting, design, construction, and operational phases of electric transmission. As an experienced, versatile partner with the local knowledge and resources to fit the needs of dynamic transmission projects as they arise, we are ready to put our expertise to work for you.

Wind

The key to more sustainable wind projects is simple – a smarter foundation. Our exclusive GripTerra family of wind turbine foundations is at the forefront of wind foundation design, offering a faster construction time while using significantly less concrete. These patented foundations also have the potential to be repowered, eliminating the need to build new foundations for the next generation of larger wind turbines.

With thousands of wind projects completed, our industry-leading teams can meet your project needs, from development and design, through construction and post-construction.

Offshore wind

Offshore wind development comes with regional challenges and specific issues that our locally based experts are already familiar with. By working with our collaborative team, we can assist with horizontal directional drilling, environmental permitting, and the evaluation, planning, siting, and development of these complex projects.

You get technology and capability at every step to help you build and maintain long, multi-state linear projects. Location intelligence services like Pivvot and Stage1 deliver essential siting information and expected geotechnical and environmental conditions fast, to make informed decisions.
