Electric Infrastructure Services
Riggs delivers end-to-end electric infrastructure solutions that prepare North America for what’s next. From high-voltage line construction to substation maintenance, our diversified, highly qualified union and non-union workforce pairs technical skills with enterprise-scale resources, ensuring projects are completed safely, on schedule, and built to withstand the grid-hardening demands of today’s energy transition.
Transmission Line Construction & Maintenance
70% of U.S. transmission lines are over 25 years old, prompting utilities to modernize the backbone of the grid (Department of Energy, 2023). Riggs is playing a critical role in transmission line modernization. We build and maintain overhead and underground transmission lines up to 500 kV. In addition to new builds, we provide upgrades, reconductoring, line relocations, right-of-way construction, and emergency storm maintenance services.
Distribution Line Construction & Maintenance
Reliable neighborhood service starts with robust distribution lines. Our turnkey overhead and underground programs include distribution line construction and maintenance, cable replacement, pole change-outs, and grid-hardening upgrades. With minimal disruption, Riggs keeps electricity flowing to homes and businesses.
Foundations for Electric Infrastructure Projects
Transmission towers, monopoles, and substations require foundations engineered for decades of service. We deliver drilled caissons, micropiles, helical piles, and deep-pier concrete placement tailored to geotechnical conditions. Our in-house geotechnical experts model load paths to ensure structural integrity, even in challenging soils or flood-prone terrain. To support foundation work on electric infrastructure projects, we routinely utilize environmental matting in wetlands and other protected areas to enable access to transmission structures.

Substation Construction & Engineering Expertise
Modern load growth and renewable integration call for agile electrical substation construction. We handle full-scope site prep, civil works, cable, transformer, and circuit breaker installation, protection and control wiring, and testing and commissioning for greenfield and brownfield sites. Whether it’s a greenfield 500 kV yard or a downtown substation building construction retrofit, our engineering team optimizes for reliability, resiliency, and future capacity expansions.
Energized Services for Utility Projects
Taking circuits offline is costly, which makes safe and efficient execution essential. Riggs’s energized (live-line) methods—bare-hand, hot-stick, high induction stringing, and insulated overhead transmission line lifts—allow line and structure repairs, substation maintenance, spacer-damper installs, and hardware replacements without interrupting power. Continuous service and rigorous safety controls make our energized portfolio a trusted option for time-critical upgrades.
Engineering & Support Services for Electric Infrastructure Projects
Riggs understands that early-stage planning saves time and capital. Our multidisciplinary engineers provide PLS CADD design, asset management, route selection, thermal rating evaluations, and complete circuit analysis. Throughout execution, we supply project controls, material management, and as-built data analytics to ensure each asset delivers full lifecycle value.
