Civil Excavation & Trenching for Underground Utilities

Our team performs precision trenching and excavation to prepare the groundwork for underground electrical systems. Using excavators and support equipment, we dig and prepare trenches for the installation of electrical conduits, raceways, and utility distribution systems, ensuring proper depth, grading, and soil preparation.

• Excavation for electrical conduit and raceway systems
• Sand bedding and compaction in rocky or specified soils
• Compliance with depth and separation requirements for electrical utilities
• Coordination with locates and underground utility providers

We handle projects of all sizes, from site‑wide distribution builds to targeted excavation for specific electrical infrastructure.

Conduit & Raceway Installation

We install a range of conduit systems including DB2 conduit, rigid PVC conduit, and HDPE pipe for primary and secondary power distribution, communications pathways, and future‑ready utility infrastructure. These conduit networks serve as the backbone of underground electrical systems.

Our conduit services include:

  • Primary and secondary power conduit systems for electrical distribution

  • Raceway installation for communications, fiber, coaxial, and control cables

  • Conduit placement for feeder lines to outbuildings, pumping stations, and sites

  • Protective measures and separation between power, communications, and lighting circuits

Conduit pathways are designed for durability, accessibility, and compliance with local and utility standards.

Concrete Vaults, Pull Boxes, & Equipment Foundations

We provide excavation, placement, and installation of concrete vaults, pull boxes, transformer pads, and equipment foundations as part of underground power distribution infrastructure. These structures protect critical electrical connections and provide accessible points for maintenance and future expansion.

Our civil electrical crews:

  • Excavate and place concrete vaults and pull boxes

  • Integrate transformer pads and switchgear foundations

  • Coordinate precision placement using boom trucks and mobile lifting equipment

  • Ensure accurate alignment with electrical design and utility requirements

Precast and cast‑in‑place vault solutions deliver secure and long‑lasting support for underground electrical infrastructure.

Lighting & Site Electrical Infrastructure

We install underground conduit and associated civil work for site lighting systems, including parking lot, roadway, and exterior facility lighting. This includes vertical infrastructure support such as pole bases, concrete foundations, and electrical connections. Our services cover:

  • Excavation and trenching for lighting circuits

  • Augering or hydro excavation for pole foundations

  • Pouring and finishing concrete lighting bases

  • Conduit installation for power and control wiring

Lighting infrastructure is integrated into the overall distribution system to ensure dependable performance and code compliance.
