The park, to be renamed the Queen Elizabeth Olympic Park once the athletes have gone home, will include a mixture of elite sports stadiums, housing and community facilities such as a school and medical centre.
BAM Nuttall will remove temporary stadiums, including basketball and water polo, double the amount of parkland, reconfigure Games-time bridges and underpasses, and link the park to surrounding communities as part of the new phase called 'Clear, Connect, Complete'.
It will also prepare the media center and handball arena for new tenants, and work on the velopark by creating a mountain-bike trail and outdoor cycle circuit.
BAM Nuttall has been working at the site the past four years.
The park will reopen in phases from July 2013.
