The ten-year Amundsen-Scott South Pole Station Replacement Project, located in Antarctica, involves buildings designed to be built above a 10,000 foot deep snow field. At the site, the temperature varies between –120 degrees and 5 degrees Fahrenheit. Consequently, the snow never melts; the snowfield is growing at a rate of about 8 inches per year, presenting a key structural challenge. The increasing snow pack in combination with the weight of the buildings generates significant settlements as the snow compacts over the life of the structures. Also, at South Pole the only relief is the Station itself, so that structures at grade quickly drift with snow.
