| Abstract: | Construction of large buildings is currently part of the major infrastructure development plan at McMurdo Station. Therefore, the overall goal of this study is to provide recommendations for selecting better-suited foundation designs for the new facilities by using existing geotechnical studies recently taken on site. Based on a detailed visual assessment of photos from the geotechnical coring conducted by a third-party consultant, we interpreted the results to indicate that ice-poor to nearly ice-free ground-ice conditions exist nearly everywhere across McMurdo Station and at a depth less than 3 m. This assessment provides foundation design options to prepare for the new development by excavating the near-surface ground-ice interval, replacing with compacted non-frost-susceptible fill material, and constructing shallow foundations with at-grade first-floor design. The benefits of the shallow foundation design include lower construction material needs, increased energy efficiency, optimized drainage and snow/ice accumulation prevention, increased seismic safety, and more appealing architecture for an austere environment. |
