Boring Projects - Arizona Underground Construction

Each of our directional drilling and horizontal auger boring projects primary objectives is to honor the environment in which we operate and restore it upon completion of your project.

To help us achieve this in your behalf, before drilling any project we classify it into one of six categories based on the diameter of the bore hole to be drilled.

The Boring Project Classification System:

(XS) Extra Small Bore = less than 2”

(S) Small Bore = more than 2” – less than 4”

(M) Medium Bore = more than 4” less than 8”

(L) Large Bore = more than 8” less than 24”

(XL) Bore = more than 24” less than 48”

(XXL) Bore = more than 48”

By classifying each bore to be drilled in advance, we are able plan for the right resources to be present during the entirety of your project.

Medium (M) to extra large (XL) directional and horizontal auger bores are our specialty.

The following projects represent some of the boreholes we have drilled over the years.

Arizona Underground Construction Project Gallery | River Crossing Directional Bore Camp

We have directional bored under creeks, streams, riverbeds, ponds and lakes.

Arizona Underground Construction Project Gallery | River Crossing Bore Exit Pit

We have successfully directional drilled waterway, creek and river utility crossings up to 2,000 feet.

Arizona Underground Construction Project Gallery | Horizontal Directional Drilling

With horizontal directional drillings steerable trenchless method of installing underground pipe, conduit, and cables we have horizontally bored water crossing projects with minimal impact to the surrounding environment.

Arizona Underground Construction Project Gallery | Corps of Engineers Directional Water Bore

Levee crossings, beneath rivers, and within levee rights-of-way using HDD and auger boring techniques provide tremendous cost savings to the U.S. Army Corps of Engineers and the pipeline industry in general.

Arizona Underground Construction Project Gallery | Underwater Utility Pipe Installation

We directionally drill and auger bore water crossings with minimal impact to the surrounding environment.

Arizona Underground Construction Project Gallery | Bore Pit 30 Deep

Our bore pits have rigorous check-in/check-out procedures, control of access and egress, ground support of portal and subsidence areas, ground support of underground areas, ground support of shafts while also following industry fire prevention and control standards.

Arizona Underground Construction Project Gallery | Downtown Bore Under Hospital

We specialize in directionally drilling challenging projects such as boring underneath an urban hospitals basement to provide a more secure route for their backup generator power lines.

Arizona Underground Construction Project Gallery | Auger Bore Sideview

Our horizontal auger boring teams specialize in drilling water and sewer projects with pipe sizes between 24 inches and 48 inches in diameter up to distances of 300 feet.

Arizona Underground Construction Project Gallery | Horizontal Auger Boring

Our jack and bore (horizontal auger boring) crews are approved to drill under various railroads including Union Pacific, BNSF, CSX and Norfolk Southern.

Arizona Underground Construction Project Gallery | Creek Crossing Bore Target

We have successfully completed bores under otherwise inaccessible creeks and waterways. Our only requirement is that we can track the drill head.

Arizona Underground Construction Project Gallery | Creek Bore

When directional boring under water bodies and areas to dangerous or difficult to navigate by foot, we use boats or wire line technology to locate the drill head.

Arizona Underground Construction Project Gallery | Airport Directional Boring

We have completed directional bores for the Federal Aviation Administration (FAA) at numerous airports (FBOs) under their runways, taxi-ways and aprons as well under both United States Air Force and Naval Air Station military airfields.

Arizona Underground Construction Project Gallery | Directional Boring Natural Gas Distribution Line Right of Way

We have directionally drilled natural gas distribution lines in right of ways (ROW) and easements for gas utilities on both state and federal lands.

Arizona Underground Construction Project Gallery | Under Street Boring and Reel Trailer

We have our own reel trailers for transporting reeled pipe to jobs when and where needed.

Arizona Underground Construction Project Gallery | Parking Lot Bore

Parking lots are often directionally bored instead of open-cut or trenched to avoid business traffic disruption while installing new electric, communication, gas, water, sewer and irrigation lines. We have directionally drilled from parking lot islands to utility easements and utility demarcs and everything else in between.
