The Donohoe Cos. Inc. plans to construct a $50 million Residence Inn by Marriott at the Founders Square project in Ballston.

D.C.-based Donohoe will break ground on the 183-room hotel in the third quarter of 2011, pending Arlington County approval. The hotel, which could be the first in Arlington to start since 2008, would be finished in 2013.

The 150,000-square-foot project would be part of The Shooshan Co.’s Founders Square, a mixed-use project at Randolph Street and Clarendon Boulevard anchored by the Defense Advanced Research Projects Agency.
