The Limbach Company LLC, a Pittsburgh-based mechanical construction and service firm, is expanding its regional office and fabrication facility in Maryland and plans to create 75 new jobs over the next three years.

Gov. Martin O'Malley and Prince George's County Executive Jack Johnson announced Tuesday that the company is moving effective March 1 from Lanham to a 40,000-square-foot space in the Brick Yard Business Park in Beltsville.

The new location will allow the company to add 75 employees to its 150 workers, state officials say.

Maryland's Department of Business and Economic Development has offered the company a $100,000 loan to assist with the cost of improving its new building. In addition, Prince George's County has offered a $20,000 loan through its Incentive Leverage Fund. Limbach is also eligible for state job creation tax credits.
