CONTRACTS TO clear and prepare the site of 2012 Olympic Park were awarded by the London Development Agency last month.
The work is split between two contractors. Morrison is responsible for the northern part of the park and Edmund Nuttall the southern half.
Halcrow is Nuttall's consultant.
Work will not start until the compulsory purchase order process ends in July 2007. The LDA has already secured 90% of the land needed for the park in the Lower Lea Valley. Both teams will have to demolish any structures on the 202ha browneld site.
They will then be responsible for remediating the land to provide suitable ground conditions before main construction works begin in summer 2008.
Heavy contamination at the postindustrial site means much of the remediation work will be done by specialist contractors, who will be appointed by the LDA. These companies will then feed into the main contractors' teams.
The LDA refused to comment on appointments as it said the tender process was ongoing.
