Engine maker Cummins Inc. plans to add 600 new professional employees in an office building it will build near its headquarters in Columbus, IN, as part of its expansion effort to keep up with burgeoning sales. The company said it expects to break ground almost immediately on the new 130,000-sq-ft facility, which will connect to a similarly sized office building that Cummins began occupying in 2009.

Cummins said this is the third expansion project of its expansion in southern Indiana over the last 12 months. Once the new building is filled, by 2013, the company said it will employ nearly 3,000 professionals – three times its local presence in 2008.

“Our success in global markets over the past few years allowed us to remain strong during the recent economic downturn and has positioned us for a period of accelerated growth,” said Tom Linebarger, Cummins president & COO. “These professional jobs will be crucial as we chart a course for future growth both here and abroad.”

He added that 2010 turned out to be the most profitable year in Cummins’ history, largely due significant growth in international markets such as China, India and Brazil.

Cummins noted that it expects further strong growth in 2011, as its key U.S. markets recover from the economic downturn, as part of a period of accelerated profitable growth over the next several years.
