The organisation argues that these are basic alterations that will streamline the delivery of the Olympic Park, designed by Edaw, HOK Sport, Foreign Office and Allies and Morrison.
The changes to the masterplan have been agreed by all involved with the bid-winning designs and will, according to the official line, result in no cost increases or delays.
The most significant changes are:
More close alliance with the existing topography of the whole Olympic Park area
Broadcast and Media Centre
Moves from the Stratford City plot to a site at Hackney Wick in the Northwest corner of the park
To accommodate the move of the Media Centre, the Volleyball courts are moved of the site to Earl's Court in East London
The temporary basketball courts are moved to a site northwest of the stadium
The fencing facilities are reduced to one hall rather than two and moved to a temporary site near Stratford City
The hockey pitches are moved to a site nearer the Olympic Village
The velodrome moves south of the A12 to make space for a new Paralympic tennis centre
