One Thousand Museum: One Thousand Museum by Zaha Hadid Architects is a high-rise residential condominium under construction in Miami, Florida, U.S.A.  The deep foundation required drilling to record depths of over 170 ft .  The 62-story building is expected to rise over 700 ft when completed in 2018, making it one of the tallest buildings in Miami.  The depths of two auger-cast piles broke a record for Miami-Dade County that had recently been set by the Porsche Design Tower in Sunny Isles Beach.  The building, which is located at 1000 Biscayne Boulevard, across from Museum Park, was designed by Pritzker Prize-winning architect Zaha Hadid.  The exotic design of the building features a curving exoskeleton partially obscuring the balconies that also serves structural purposes, allowing the interior space to have fewer columns.  The effect of the design and height on wind loading is part of the reason the foundation had to be exceptionally deep.  The building is considered ultra-luxury, containing about 83 large units priced at about double the cost per square foot of nearby condominium towers, with amenities possibly including a rooftop helipad.
