When a national telecom carrier needed conduit placed to spec at an FAA-regulated site in central Florida, they called AMDDS. Here's how the job came together.

Underground conduit installation and handhole placement at an FAA-regulated VOR navigational aid facility.

FAA sites don't leave room for shortcuts. Between permitting requirements, grounding standards and the need to protect active navigational infrastructure, every decision on this job had tp be right the first time.

Scope of Work:

The scope covered full underground conduit placement from the site entry point to the building, including innerduct, pull strings, tracer wire, and a maxcell fabric duct system, all installed inside a 4-inch host conduit bore. The run extended over 1,000 linear feet to reach the facility building.

From there, the work extended into handhole placement, building entry, and interior rough-in:

17 precast 24×36 tier-rated handholes were set to telco spec and bonded with ground rods and ground wire, meeting the grounding requirements for an FAA facility.

A galvanized steel pipe was run from the last handhole to the building, bonded to the existing building counterpoise — standard practice for maintaining ground continuity on a protected site.

A lockbox and building penetration were installed at the point of entry, keeping the pathway secure and code-compliant.

A 4×4 fire-retardant backboard was mounted inside and painted with fire-retardant paint, ready for termination equipment.

Details:

Our utility locating team cleared the bore path before a single drill entered the ground. On a regulated site with existing underground infrastructure, that step isn't optional — it's the foundation of a clean job. Horizontal directional drilling let us place the conduit without open-cut disruption to the facility grounds or operations.

Handhole placement followed a coordinated layout to maintain proper span spacing and grounding continuity across the entire run. Every box was set level, bedded correctly, and bonded to spec before the lids went on.

The building entry was made clean: the galvanized pipe transition, the lockbox, and the fire-rated backboard were all finished to telco infrastructure standards,  the kind of detail that matters when the next crew on site is a carrier tech expecting a ready-to-use pathway.

The Result:

The project was completed on schedule with zero safety incidents. The carrier now has a compliant, future-ready conduit system in place at an active FAA facility — installed by a crew that knew what the job required and executed it cleanly.
