The Army Inspector General also opened an investigation of Balfour Beatty, an Army spokesman said. After reviewing the incentive fee system for all of its housing partners earlier this year, the Army docked more than 50% of Balfour Beatty's bonuses at bases including West Point in New York, Fort Eustis-Fort Story in Virginia and Fort Detrick-Walter Reed in Maryland. Other housing landlords also had fees withheld. The Air Force had already suspended all incentive fees to Balfour Beatty and referred allegations of fraud at four bases to the Air Force Office of Special Investigations and the Federal Bureau of Investigation. The new safety concerns at Tinker included a fire in a row home at Tinker in July. The Air Force said it discovered fire code violations involving 77 duplexes built by Balfour Beatty.
