Nuttall will procure and manage a number of specialist subcontractors to deliver the landscaping and public realm within the northern section of the Olympic Park in Stratford, east London.
The contractor, which has been delivering the demolition and remediation of the southern section of the Olympic Park, will now be responsible for hard and soft landscape works including tree planting and the construction of the concourse which will link all the venues, entrances and parklands.
The contract will also include the creation of new wetland and other wildlife habitats, installing new allotments and permanent park furniture, lighting, irrigation and drainage.
ODA head of parklands and public realm John Hopkins said: "This is another important step towards the creation of the parklands that will both enhance the experience of the Games for spectators, athletes and TV viewers and leave a fantastic new green space in legacy.
"The project is on track and we will be working with our contractor to quickly roll-out the process of buying the tree and plant packages for the whole of the Park."
A contract for the landscaping of the south of the park will be issued later in 2008.
