- Аннотация: The report is dedicated to the study of various approaches in regards to the reconstruction of residential buildings and structures in the Arctic zone using a risk-based approach. The aim of the research is to develop methods that take into account the specific climatic and geological conditions of the Arctic in view to minimising risks in the design and construction works. The objective of the study includes the following (i) analysis of existing methodologies, (ii) assessment of their applicability in Arctic conditions and (iii) development of new approaches that take into consideration the regional specificities. The relevance of the topic is due to the growing interest in the development of the Arctic and the need to ensure the safety and comfort of living in harsh climatic conditions.The study uses data on climatic and geological peculiarities of the Arctic zone, as well as modern methods of risk analysis. Modelling and forecasting methods have been applied to assess the impact of various factors on the stability and durability of buildings. Expert judgements and empirical data from research and monitoring of existing construction projects in the Arctic have also been used.The results of the study have shown that the application of a risk-based approach can significantly improve the reliability and safety of reconstructed buildings in the Arctic zone. Key risk factors were identified, such as interalia geotechnical risks, risks of heat losses and energy efficiency of buildings, specificity of building materials, risks in adapting to changing climate, transport and logistics. An algorithm for calculating the degree of risks in the reconstruction of buildings and structures in the Arctic zone was designed accordingly, which includes 4 actions. The formula for assessing the degree of risks in reconstruction in the Arctic zone is developed. Weight characteristics of each risk factor are determined by the method of expert evaluations. Variation of each risk factor at three levels: unsatisfactory, good, excellent is performed. An adapted scale for qualitative assessment of the degree of risk in reconstruction in the Arctic zone was also developed.The details of the obtained results have an important practical significance for construction and reconstruction of facilities in the Arctic. This implies that the recommendations can be used in the design and planning of construction works, which will reduce the probability of accidents, risks and hazards, thus increase the durability and life span of buildings. The implementation of the proposed methods shall largely contribute to the sustainable development of infrastructure in the Arctic zone, hence ensuring the safety and comfort of living.Keywords: Arctic, reconstruction, residential buildings, risk-based approach, climatic conditions, geological features, wind loads, construction technologies, efficiency improvement
