Underground Construction

Underground Fiber Construction

HDD, plow, trench, microtrench, and vault placement — wherever the route demands.

Underground fiber construction is where program risk concentrates: locate accuracy, restoration quality, traffic control, and bore documentation are the difference between a program that closes on schedule and one that loses a season to rework. FCC's underground crews and vetted construction partners run the full spectrum of placement methods — directional drilling, mechanical plow, open-cut trench, microtrench, and surgical urban placement — with the locate discipline and as-built documentation that keep programs auditable from day one.

What FCC Delivers in Underground Fiber Construction

From rural long-haul backbone to dense metro overbuilds, FCC matches placement method to terrain, restoration scope, and program economics. We field directional drill rigs from 2"-12" class, vibratory and static plow tractors, rock saws, and microtrenchers — paired with vault, handhole, and pedestal crews and a full restoration capability that closes the loop with municipalities and DOT inspectors.

Capabilities at a glance

  • Horizontal Directional Drilling (HDD) — 2" through 12" bores
  • Static plow and vibratory plow placement on rural and suburban routes
  • Open-cut trenching and rock saw on hard-rock conditions
  • Microtrenching for urban FTTH overbuilds
  • Vault, handhole, and pedestal placement
  • Full surface restoration: concrete, asphalt, sod, landscape repair
  • MUTCD traffic control and DOT-compliant work zones
  • 811 locate ticket management and damage-prevention discipline

How We Run an Underground Build

Every FCC underground build opens with locate verification, sub-surface utility engineering review, and a daylight-and-pothole pass on critical conflict points. Our HDD operators are documented with bore logs that capture entry/exit, depth, deviation, and pull-back — closed out into the GIS as-built we hand back to the program. Restoration is treated as part of the build, not an afterthought: we close municipal coordination, DOT permits, and final inspections in the same sprint as cable placement so program managers don't carry restoration risk into close-out.

Standards, Equipment & Safety

FCC underground operations comply with OSHA excavation and confined-space standards, MUTCD traffic control, and DOT-specific work-zone requirements. Our HDD operators carry HDD-specific damage-prevention training, and every crew runs daily JSA briefings against site-specific hazards. The fleet ranges from compact urban rigs for tight-quarter microtrench through Class 4 and 5 directional drills capable of long-pull intercity runs — owned where it matters and partnered where capacity demands.
