Booming Business South Fayette company continues to shape the future of new landscapes. by Earl Bugaile 28 724.942.0940 to advertise | South Fayette I t would be quite easy to say that business is “booming” for Senex Explosives Company. Yet, out of this unobtrusive block structure located along Miller’s Run Road in South Fayette, Senex has been changing landscapes in all parts of the United States by helping contractors and builders create new buildings, highways, transit terminals and virtually moving mountains for many years. Established in 1992, from a company formerly known as H.L. & A.G. Balsinger, Inc., Senex staff have been involved in the development of the site of the Midfield Terminal at Pittsburgh International Airport. They have also assisted in the construction of the Allegheny County Port Authority transit tunnels between Mt. Lebanon and Dormont. Senex has also completed highway projects for PennDOT, PA Turnpike Commission, the West Virginia Department of Transportation, and others. It has recently completed site preparation for a 1.9 billion dollar power plant in Wise County, Virginia, and in the last two years, worked with CSX Transportation to open rail tunnels in Somerset County, as part of the CSX National Gateway. The CSX project will allow the rail carrier to haul double stack container trains between the ports of the East Coast to Chicago and the Midwest. “The most challenging and memorable project of my career,” is how Senex General Manager Dale L. Ramsey described the rail project which took place over a two-year period between 2011 and 2013 in Somerset County where crews from Senex and Joseph Fay Contractors of Tarentum removed three tunnels as part of the National Gateway. It was not only a task to move more than 1.2 million cubic yards of rock and earth while excavating one tunnel alone, but another challenge to keep some 40 trains a day running on a close-tonormal schedule around, under and through the construction area. Senex coordinated the work with a CSX coordinator at the site, who stayed in touch with train crews and train dispatchers in Jacksonville, Florida, to “platoon” freight trains and Amtrak’s daily Capital Limited through both the tunnels and a run-around track that was built to handle traffic while one tunnel, the Pinkerton, was demolished. The Pinkerton tunnel project also proved to be one of the most interesting for Senex crews. Built in 1885, the Pinkerton tunnel was constructed of hand-cut stone and brick. It was 1,080 feet long and built along a curve next to the Casselman River and the Great Allegheny Passage, the 150-mile bike and hiking trail between Pittsburgh and Cumberland, Md. Part of the challenge to the project was not only opening the tunnel, but to preserve the integrity of the former Western Maryland Railroad’s Pinkerton tunnel which was built adjacent to the one being opened on CSX. Although the tunnel along the Great Allegheny Passage has been closed and trail users detour
