DESCRIPTION
More than 1,500 cast units have been delivered and installed, which equates to more than 38,000 cubic meters of concrete and 1,000 kilometers of post-tension cable.
A project of such a scale required a thorough rethinking of processes; the methods of delivery and installation had to be extended and roads and bridges had to be temporarily reinforced to allow the passage of large prefabricated elements and equipment.
The limits of the concrete were pushed with the first ever use of superplasticizers in North America..
