Liberty Mutual Group has announced that it is planning to open a new office in Springfield, Massachusetts, in the third quarter of 2008.

The company has signed a 10-year lease for office space on Federal Street in the STCC Park, formerly the Springfield Armory.

The new Springfield office will host a variety of business operations, including a customer service call center to support Liberty Mutual’s car and home insurance business in Massachusetts as well as the rest of the country. Other operations will include claims and legal administration.

Liberty Mutual will start hiring and training for the office this spring and plans to have over 150 employees in place by year-end.
