Duct Banks & Conduit

Concrete-encased duct banks, multi-way conduit, and the vaults and pull boxes that make up the underground pathway for primary distribution and communications.

What We Provide

Duct Banks & Conduit — in detail

Concrete-encased duct banks, multi-way conduit runs, manholes, and vaults — here is how we build the pathways that primary distribution rides on.

Duct Banks & Conduit

  • Concrete-encased duct banks — For primary feeders and critical runs we build concrete-encased duct banks — racked, spaced, and tied conduit encased in concrete to protect and identify the run.
  • Multi-way conduit runs — We install single and multi-way conduit in PVC, fiberglass, or steel, sized and arranged for the conductors plus spare capacity for the future.
  • Mandrel and proofing — Every duct is mandreled and proofed so conductors pull clean — no surprises when it is time to wire.

Vaults, Manholes & Pads

  • Pull boxes and hand holes — We set the pull boxes and hand holes that let conductors be pulled and spliced along a long run.
  • Manholes and vaults — We set precast manholes and vaults for primary distribution, with the racking, grounding, and sumps they require.
  • Transformer and switchgear pads — We form and pour the pads and stub up the conduit for pad-mounted transformers, switchgear, and equipment.

Coordination & Records

  • Stub-ups and terminations — We stub conduit into buildings, gear, and equipment at the right location and elevation, ready for the electrical crews to land.
  • Utility and trade coordination — We coordinate duct-bank routing with the utility, wet utilities, and other trades so crossings and code separations are right the first time.
  • As-built documentation — We record the installed routing and depths so the owner knows exactly what is in the ground.

Where It Applies

Markets we serve

Duct bank work takes our Tucson crews to campuses, industrial plants, and municipal and utility projects across Arizona.

  • Primary distribution
  • Campus and site power
  • Communications backbone
  • Utility coordination
  • Industrial and commercial

The Design-Build Advantage

Designed, self-performed, and accountable

A duct bank is excavation, conduit, concrete, and survey tolerance all at once. Self-performing all of it means the bank lines up with the gear pads — and the cable pull goes smoothly the first time.
