London's 2012 Olympic Park Opens After Years Of Preparation
Hosting the Olympics is a massive undertaking for the host city. In 2006, London demolished more than 200 buildings to make room for what would eventually become the Olympic Park. When those buildings were demolished, an impressive 98 percent of the materials were reused and recycled in the construction of the Olympic Park and elsewhere. The Olympic Park was built on former industrial brown fields, which cleaned up before the games. About 1.4 million cubic meters of contaminated soil was excavated from the site, and five enormous soil washing machines were brought in to wash the soil and filter out oil, tar and heavy metals.
After the 2012 Summer Olympics are over, the Olympic Park will again be transformed. In 2013, the roughly 500 thousand square meters Park in East London will reopen as Queen Elizabeth Olympic Park. The 114.5-meters tall ArcelorMittal Orbit will still tower over the park, and the Olympic stadium will be downsized to a permanent stadium that will seat 25 thousand people.
