ISG’s “Construction Management” contract also includes providing infrastructure for the opening and closing ceremonies and installing the world’s largest temporary dining hall for competitors.

ISG will manage ‘overlay’ at the venues during the London 2012 Games – which includes temporary spectator seating, tents, cabins and platforms as well as utilities, fire safety, specialist sports lighting and drainage.

The contract incorporates the preparation, delivery and removal of all temporary facilities and services at venues, including the Olympic Stadium, Velodrome, Aquatics Centre and Water Polo Arena, Media Centre, Olympic and Paralympic Villages, Basketball Arena, Hockey Centre, Handball Arena and at Eton Manor.

ISG will directly manage the infrastructure requirements for the opening and closing ceremonies in the Olympic Stadium, as well as the installation of the largest temporary dining hall structure in the world, capable of serving 50,000 covers in one sitting.

David Lawther, CEO of ISG, said: “This latest award builds upon ISG’s relationship with the London 2012 Games, following the successful completion of the award-winning Velodrome and the delivery of the 2012 BMX facility.

“The continuation of our close relationship with the London 2012 Games is an outstanding success for our project teams and a major acknowledgement of our capabilities.”
