Fiber Optic Installation
Telecommunications and directional drilling are what 406 Underground specializes in — and fiber is where most of that work goes today.
Fiber Optic Installation from 406 Underground
We place fiber conduit and innerduct by boring, plowing or trenching — whichever fits the ground and the route — and set the handholes, vaults and markers the network needs.
From long rural runs to neighborhood laterals and individual drops, crews work cleanly, locate every crossing and leave the right-of-way the way they found it.
What we do
- Fiber conduit and innerduct placement
- Directional bores for road, driveway and waterway crossings
- Plowing for long rural routes
- Handholes, vaults and pedestals
- Service drops to homes and businesses
- Locate wire and route markers
How it works
Route review
We review the design, permits and existing utilities along the route.
Place pathway
Conduit goes in by bore, plow or trench.
Structures
Handholes, vaults and markers are set.
Restore
Yards, shoulders and surfaces are restored.
Why it pays
- Right method for each section of the route
- Clean right-of-way work
- Telecom-focused experience since 2003
“The crews not only provide accurate bores, but also take responsibility for their actions and clean up after themselves without being asked when leaving a jobsite. Four O Six is also proactive in locating utility crossings… Montana owned and operated, this company has a family touch to it and it shows in their desire to do a good job at a minimal cost.”
— Rob Hanson, PE, Contractor for NorthWestern EnergyQuestions
