In January and February of 2011, the first of the large 72-inch-diameter piles were driven 160 feet in to the sea floor at Piers 15 and 17 in San Francisco, the new home of the Exploratorium. These new piles were installed between the two piers and along the south apron of Pier 15. In early March, the steel casings were filled with concrete.
