Accident Fund Insurance Company of America has started to transform the Lansing (Mich.) Board of Water & Light's Ottawa Street Station power plant into its new national headquarters. The $182 million project includes the conversion of the main structure into 160,000 sf of office space and the construction of a 120,000-sf office building and a 1,000-car parking garage north of the power plant. The headquarters will feature a four-story atrium that will connect the refurbished Ottawa Street Station property to the building's addition. Construction on Accident Fund's seven-acre campus will begin in 2009, with completion slated for 2011. Lansing-based Christman Company will act as the developer and owner for the project. Accident Fund will lease the property with an option to buy.
