Illinois-based construction and mining equipment manufacturer Caterpillar Inc. selected Tucson as the new location for the manufacturer’s surface mining and technology offices, according to an announcement from the office of Gov. Doug Ducey.

This new facility is expected to add 600 new jobs in the state over a five-year period, offering positions in management, engineering, product development and support positions, according to the governor’s office.

The state estimates the new offices will have a $600 million economic impact. Caterpillar has been operating in Arizona for 70 years, and the new facility will boost Caterpillar’s employment base to 1,000, according to the governor’s office.

“This decision positions us to build on the tremendous capabilities present at our Tucson Proving Grounds and Tinaja Demonstration Center and deliver the next generation of mining technology and leadership,” said Tom Bluth, Caterpillar vice president with responsibility for Surface Mining and Technology.

Caterpillar will lease approximately 40,000 square-feet at 97 E. Congress St., in Tucson for now, according to the statement.
