To date, there is no comprehensive geotechnical monitoring of pile foundations for residential and industrial buildings in Russian regions located in the permafrost zone and, accordingly, there is no reliable information about which part of them annually undergoes deformations caused by changes in geocryological conditions. This study presents the results of fieldwork on inspection of buildings in Amderma village (Zapolyarny district of the Nenets Autonomous Okrug, the North-East of the European part of Russia, part of the Arctic zone of the Russian Federation). The article presents the main reasons for the deformation of buildings in Amderma. Data were collected on climatic and permafrost conditions and their dynamics, construction features and the current state of engineering structures of Amderma. Based on studies of engineering structures, a general description of the buildings is given. It was identified that in 2021, 59% of the total number of buildings were deformed, of which 80% were wooden, 46% brick and concrete, and 31% buildings made of light structures. Thus, only 40% of the heat-generating facilities in Amderma are not deformed. The main factors of foundation deformations are identified: soil salinity; watering underground or directly near the building; thermokarst in the building area; coastal processes; rise in temperature due to climate change or creep in the base soil. The results of the study made it possible to fill in local information “gaps” for the Arctic coast of the Nenets Autonomous Okrug in the range of works devoted to the problem of buildings and structures deformations. The new results obtained can be integrated with other similar studies.
