Rockford completed a total of 134 miles of 36-inch pipeline as part of the M2E3 project. Segment 4 was laid in mostly dense rock formations that required blasting and rock trenching while Segment 7 was very congested, running through pipeline corridors south of Houston. Included in Rockford's scope were 26 horizontal directional drills, 188 bores, and 15 mainline valves. Welding was performed using a combination of CRC's automatic welding system and manual stick rod.

Rockford constructed 77 miles of 36-inch and 49 miles of 30-inch for a total of 126 miles of pipeline from Lake Wales, FL to Okeechobee, FL. The project included 12 directional drills totaling 25,637 feet, 63 road bores totaling 8,089 feet, 30 open-cut roads, an interconnect, and a large meter station at the south end of the project. There were 5 successful mainline test sections to complete the project.

The Rancho Pipeline Expansion Project for Enterprise Products included the construction of 86 miles of 36-inch pipeline near Houston, TX. A total of 18 horizontal directional drills, 14,600 feet of bores, and the placement 62,000 timber mats were needed to complete the project.

Rockford constructed 31.4 miles of 42-inch in OH for Kinder Morgan/Conoco Phillips.

Rockford constructed Spreads 6 and 7 of the Ruby Pipeline Project for El Paso Natural Gas which ran from Vya, NV to Malin, OR. Totaling 127 miles of 42-inch pipeline, this challenging project included winter work, multiple winch line hills, large waterbody crossings, and the utilization of over one million pounds of dynamite for the excavation of both grade and ditch rock.

Rockford constructed Spread 6 of the Sabal Trail Pipeline Project as well as the Hunter Creek Lateral for Spectra which consisted of 76.6 miles of 36-inch pipeline that ran from Near Wildwood, FL south to Kissimmee, FL. Included in this project were 6 horizontal directional drills, 30 road bores, 6 mainline valves, and the utilization of 135,000 timber mats.

Rockford constructed over 125 miles of 8-inch to 24-inch in PA for Williams Midstream.

This project involves a complicated, single microtunnel drive with the installation of 372 feet of 96-inch diameter steel casing pipe launched from a chamber tunneled under the Anderson Dam and recovered in the Anderson Reservoir. The microtunnel boring machine (MTBM) lake tap is launched from inside of a 24-foot Horseshoe tunnel mined chamber under the Anderson Dam, this 1,600-foot conventional tunnel will incorporate steel horseshoes and a reinforced concrete lining. A reaction frame and portal launch seal are used to tunnel from the chamber to a lake tap Landing pad deep below the surface of the Anderson Reservoir where the MTBM is recovered using specialty divers, barges, and cranes.

This project consisted of a single microtunnel drive of 696 feet of 64-inch diameter x 0.75-inch wall Trinity Products Tri-Loc Weldless Steel Casing. The microtunnel was installed under two frontage roads, an active railroad, and four lanes of Interstate 90 progressing through silts, sands, gravels, cobbles, and boulders beneath the groundwater table.

This project consists of installing fiberglass reinforced pipe (FRP) sanitary sewer totaling approximately 3,600 feet of 42-inch diameter and 990 feet of 48-inch diameter. The pipe installation is completed in five separate tunnel drives all at approximately 30 to 35 feet in depth with the tunnel reaches varying from approximately 700 feet to 1,000 feet. The entirety of the project is below the natural groundwater table through soils that are saturated with contaminated water requiring extensive coordination with the City of Houston to provide water-tight shafts and mitigate all potential environmental impacts.
