Milestone Companies was under contract to install 3.5 miles of 8” steel pipe along E-470 in Colorado. This pipe lays in the same ditch where Milestone had another project which included the installation of a 20” gas pipeline. Because of this additional pipe in the mix, Milestone had to take extra precautions to ensure safety standards were met.
The bore under E-470 proved to be the biggest challenge faced throughout the project. Rather than using tracking wires across the freeway, E-470 Engineers and the Milestone team deemed it necessary to use a gyro to steer under the freeway.
