Underground Infrastructure Technologies

What Underground Infrastructure Technologies does

Underground Infrastructure Technologies, LLC (UIT) is a Lakewood, Colorado-based specialty contractor that delivers trenchless underground utility installation and rehabilitation for public and private clients across the Rocky Mountain region. Founded in 2014 as a wholly owned subsidiary of Harrison Western Construction Corporation, the firm operates as the parent company's trenchless division, sharing leadership (Joe Diesslin serves as President of both entities) and back-office resources. UIT combines multiple installation methods — guided and unguided horizontal auger boring, slurry microtunneling with MTBM, full-scale tunnel boring machine (TBM) work, pneumatic pipe ramming, conventional hand tunneling within shields, and large-diameter segmented sliplining — to address projects ranging from $50,000 to over $75 million in size and from 20 inches to over 142 inches in diameter.

The firm serves municipalities, counties, water and sewer authorities, Class 1 railroads, federal and state agencies, departments of transportation, and private industrial clients (e.g., Suncor Energy), with named projects including the award-winning Cottonwood Siphon 142-inch sliplining rehabilitation for the City of Loveland, microtunneling under light-rail and rail crossings for the City of Denver at 40th and Blake, and multiple guided auger bores for the City of Broomfield. Its technical differentiator is the combination of geotechnical engineering capability (licensed PEs across 18+ states, a Diplomate Geotechnical Engineer on staff) with practical execution in challenging ground conditions including boulders, loose alluvium, raveling soils, and unknown underground obstructions.

UIT generates revenue through project-based contracts procured via competitive bidding on public infrastructure work and direct engagement with private sector clients, engineering firms, and general contractors. Pricing is quote-based with no published rate card; projects are billed as multi-year unit-priced contracts. Marketing is relationship-driven (company website project portfolio, LinkedIn presence, industry awards) rather than outbound. The company holds contracting licenses in eight states and most Colorado counties and municipalities, giving it a prequalified bidding footprint that exceeds its current Colorado-centric operating geography.

Functional benefit

Products and services

• Guided and Unguided Horizontal Auger Boring A trenchless installation method that forms a casing or pipe under railways, roads, and structures without open-cut excavation. Suitable for diameters including 20"-36" (standard) and 42"+ sizes, used by municipalities, agencies, and private owners needing to install or replace underground utilities beneath surface obstacles.
• Microtunneling A remotely controlled, laser-guided trenchless installation method (MTBM) used to install pipe to precise line and grade tolerances, ideal for gravity sewer and other high-accuracy utility installations. Capable of handling challenging ground conditions and used for municipalities and developers requiring precision installation.
• Tunnel Boring Machine (TBM) Operations Mechanized tunneling using a tunnel boring machine for larger-diameter and longer-drive underground installations, supporting tunnel programs beyond the diameter range of typical auger boring or microtunneling equipment.
• Pipe Ramming / Pipe Jacking A trenchless installation method that uses a percussive hammer to drive a casing or pipe through the ground, often for steel casings under roads or rails. Used where ground conditions or project requirements make pipe ramming the most efficient installation option.
• Hand Tunneling Conventional hand excavation method used for short, small, or specialty tunnel drives where mechanized equipment is impractical, including utility installations in tight urban or industrial environments.
• Sliplining A trenchless rehabilitation method that pulls or pushes a new, smaller-diameter pipe inside an existing host pipe, restoring service and extending asset life. UIT performs sliplining on diameters up to and greater than 142 inches.
• Tunnel Rehabilitation Services to extend the life of existing underground infrastructure, including sliplining and related rehabilitation methods, used by municipalities and owners needing to renew aging tunnels and pipelines without full replacement.
• Geotechnical Services Pre-construction geotechnical assessment, planning, design, and permitting support for tunneling and underground utility projects, leveraging the technical background of UIT's leadership team including a Diplomate Geotechnical Engineer.

Emerging players

• Northwest Pipe Company: Manufacturer and installer of engineered steel pipe systems for water, wastewater, and trenchless applications. Adjacent rather than direct competition, but comparable in serving underground water/sewer infrastructure projects.

Broad incumbents

• Aegion Corporation: Public infrastructure services company with trenchless rehabilitation and installation subsidiaries (including Insituform). Comparable in sliplining and tunnel rehabilitation offerings, though operating as a much larger diversified infrastructure services platform.
• Michels Corporation: Large diversified infrastructure contractor with a substantial trenchless utility installation division offering microtunneling, auger boring, and pipe ramming services nationwide. Directly comparable on core trenchless methods, though operating at a much larger scale across multiple construction segments.

Regional players
