I Innovative technologies are just one reason Springboro, Ohio-based Kelchner Inc. became one of the 20 largest excavation companies in the United States. The company, founded in 1948, was one of the first contractors in the United States to start using GPS, and today more than 90 percent of its equipment uses machine control. Founded in 1948, Kelchner was a family-owned business until the end of 2015, when it was acquired by Houston- based Wood Group—a $7-billion company that serves the energy sector in more than 50 countries. The Ohio company continues to work in its specialty areas of large site development and energy sector work, noted Troy Norvell, a Kelchner executive who now has the title of President, U.S. Onshore East with Wood Group. Some of the company’s recent and current projects include site work for the 2-million-square-foot Sofidel plant in Circleville, Ohio, and earthwork at the 650-acre site for the Volvo car manufacturing plant in Charleston, South Carolina. “We focus on large projects that are fast paced where we can flex our muscles and demonstrate who we really are,” Norvell said. The company began using Topcon systems for machine control about a decade ago and started using Komatsu intelligent Machine Control (iMC) machines two years ago. “The Komatsu i-machines really fit into what we are trying to do,” Norvell said. And Komatsu’s fully-integrated, machine control system eliminated the need to fight with cables and antennas that come with add-on systems. iMC offers several benefits for the kinds of projects Wood Group performs. “We do a lot of work where we are creating contours and doing slope construction,” the kind of work that requires lots of staking, checking and rechecking when using conventional equipment, he noted. Using iMC machines allows the company to eliminate staking and still meet quarter-inch tolerances. “Having a machine that is capable of delivering a high degree of accuracy without having to stop and check grades eliminated people on the ground. It sped things up 100 percent compared to where we used to be.” Kelchner Inc./Wood Group: TRUST IN KOMATSU iNTELLIGENT MA CONSTRUCTION DIVISION: iMC “Having a machine that is capable of delivering a high degree of accuracy without having to stop and check grades sped things up 100 percent compared to where we used to be.” Troy Norvell; President, Kelchner Inc./Wood Group 14 Valued at over $2-million, the Fedex Miamisburg site development project involved moving over 150,000 cubic yards of dirt and over 20,000 tons of aggregate—a perfect application for Kelchner Inc., Operator Sean Copley … and the Komatsu D39PXi iMC crawler dozer.
