Polar camps require frequent relocation due to burial by drifting snow or site contamination by camp waste. Jamesway buildings up to 64 feet long are widely used in polar camps at outlying work centers and construction projects. In order to eliminate the labor required to completely disassemble and reassemble these buildings for relocating them, a mobile foundation for Jamesways up to 64 feet long was developed. This steel foundation is hinged 32 feet from the end to reduce bending moment when more than a 32-foot length is used, and is cross-braced in each 16-foot length to keep it square. A prototype 64-foot-long foundation was given two tests on snow near McMurdo, Antarctica. It was loaded with weights to simulate the weight of a Jamesway, and towed 3 miles without damage over terrain which had ridges up to 2 feet high. The following season, a Jamesway was erected on the foundation, and the building was towed 1 mile without damage. It was concluded that the mobile foundation provides a suitable means for relocating completely assembled Jamesways in the same general area, and that its use would produce significant savings in reduced building damage, manpower, and reoccupancy time. It was recommended that the mobile foundation be used in all areas where Jamesways up to 64 feet long require frequent relocation. Author
