Underground Electrical Construction

Nevantin Services builds the civil side of underground power: duct banks, conduit systems, vaults, and trenched or bored raceway for utilities, developers, and electrical contractors across 12 states.

What We Do

We install the underground raceway that power runs through: open-cut and bored conduit, concrete-encased duct banks, manholes, vaults, and pull boxes — built to the utility's or engineer's specification and proofed before turnover.

Electrical contractors and utilities bring us the civil scope — the digging, boring, duct, and structures — so their crews can stay on the wire. Developers bring us the whole underground package, power raceway alongside water, sewer, and fiber in one coordinated build.

Duct banks and conduit systems

A duct bank is engineered civil work: conduits spaced and secured, concrete encasement where specified, marker tape and tracer, mandrel-proofed and pull-stringed before anyone calls it done. We build single-conduit road crossings and multi-way banks feeding substations, campuses, and data centers — including the long bored crossings where open cut isn't an option, via our HDD practice.

Where we fit next to the electricians

Energized work belongs to licensed electrical contractors and utility crews; our lane is the civil construction that comes first — excavation, raceway, structures, backfill, compaction, restoration. That split is standard on utility and commercial projects, and it's why electrical firms subcontract the underground scope to a utility contractor rather than putting journeymen on shovels.

Dig-once with everything else

Power raceway rarely travels alone. In new developments we build it in joint trench with communications and gas where separation rules allow — one cut, one restoration — and our fiber practice means the empty conduit that should accompany every power trench actually gets placed.

Common Questions

Are you a licensed electrical contractor?

We build the civil scope — trenching, boring, conduit, duct banks, vaults. Terminations and energized work are performed by licensed electrical contractors or the utility; we work alongside them daily.

Do you proof and document the duct?

Yes — mandrel and pull-string every way, with as-builts showing depths, offsets, and structures.

Can you bore power conduit under existing streets?

Yes; bored crossings and long directional bores for electrical duct are core work for our drill crews.
