Olympic Delivery Authority (ODA) head Dennis Hone has defended exit payments paid to 144 officials, which amounted to £2.8m in 2012-13.
Chief executive Hone was paid £80,000, plus £373,000 for his pension.
"I'm very proud of what has been achieved by myself and my colleagues," Hone told BBC Sport.
"We delivered all of the venues a year before the Games and a billion pounds under budget. All of these payments were made under contract."
The OAD annual report noted that Hone was entitled to receive statutory redundancy pay and a terminal bonus equivalent to 60% of his salary as part of his employment rights.
An ODA spokesman said hiring the best people required many to give up long-term jobs elsewhere.
Shortly after he was made redundant Horne was appointed chief executive of the London Legacy Development Corporation.
