Underground Construction

Underground Fiber-Optic Construction Services

At Goliath Utilities, our underground construction capabilities deliver robust, future-proof fiber networks—whether deploying along busy roadways, beneath city streets, or across sensitive landscapes. From precision trenching to advanced directional boring, we ensure minimal disruption, maximum reliability, and full compliance every step of the way.

Advanced Subsurface Planning

  • GIS-Driven Route Design: Using detailed terrain and utility-mapping data, we optimize alignment for minimal environmental impact and simplified permitting.
  • Subsurface Utility Engineering (SUE): Comprehensive locating and vacuum-excavation surveys prevent costly conflicts with existing gas, water, or power lines.
  • End-to-End Permitting: We navigate municipal, county and state regulations—securing highway, railroad and DOT permits to keep your schedule on track.

Precision Trenching & Microtrenching

  • Open Trenching: From 12″ distribution trenches to deeper duct banks, our crews maintain precise grade control, backfill compaction, and restoration to original surface conditions.
  • Microtrenching: Ideal for urban corridors, we cut narrow, shallow trenches (often under 1″ wide) to house microducts—reducing pavement restoration costs and permitting delays.
  • Environmental Stewardship: Trenchless transitions under driveways, sidewalks and sensitive areas preserve landscapes and infrastructure.

Horizontal Directional Drilling (HDD) & Boring

  • High-Pressure HDD: We employ state-of-the-art rigs for bores exceeding 1,000 ft—installing conduit under rivers, highways and existing utilities with minimal surface impact.
  • Auger Boring & Pipe Ramming: When HDD isn’t feasible, our auger-boring crews deliver straight-line bores for duct banks beneath tight rights-of-way.
  • Conduit & Microduct Installation: Single- and multi-duct systems are installed with meticulous tension control, ensuring long-term integrity and easy future expansions.

Vaults, Manholes & Handholes

  • Custom Vault Construction: Precast and cast-in-place vaults sized to your network architecture, with built-in cable-management and splice bay provisions.
  • Handhole Deployment: Strategically placed, fiber-rated handholes provide access points for splits, testing and maintenance—minimizing OPEX.
  • ADA & Traffic-Rated Designs: All structures meet or exceed ADA, NEMA and roadway load-rating requirements for safe public integration.

Quality Assurance & Network Turn-Up

  • Fiber Blowing & Pulling: High-capacity blowing machines and tension-monitored pulls prevent micro-bends and cable strain.
  • Optical Testing & Certification: We perform OTDR, insertion-loss and continuity testing—delivering “as-built” test reports and full documentation for your records.
  • As-Built Mapping: GIS-anchored deliverables include detailed maps of every conduit, vault, splice and drop, ensuring seamless future maintenance and upgrades.

Safety & Compliance Culture

  • OSHA & DOT Standards: Our crews are trained in confined-space entry, trench-safety shoring, traffic-control flagging and trenchless-operations protocols.
  • Restoration & Site Cleanup: Following completion, we restore pavements, sidewalks and landscaping to pre-construction condition—leaving work sites cleaner than we found them.
  • Community & Stakeholder Coordination: Proactive notifications, public-information signage and on-site liaisons keep neighbors and agencies informed throughout construction.
