- The document discusses the enabling works conducted at the Olympic Park site in London for the 2012 games, including taking possession of the land, extensive site investigation and remediation, treatment of contaminated soils, relocation of businesses, and construction of venues and infrastructure that transformed the area. - Over 2,800 intrusive site investigations were conducted, with over 44,000 meters sampled and tested for ground and water conditions and contamination. Treatment methods included soil washing, stabilization, and bioremediation to treat over 800,000 cubic meters of excavated soil. - The remediated site supported the construction of the Olympic venues and was transformed from a largely vacant and contaminated site to a space that successfully hosted the 2012 games
