Abstract: This article considers the problems of obtaining construction products in winter, along with complex technological processes, in the light of scientific achievements and analysis of influencing factors when solving thermophysical problems, as well as evaluating the results on production indicators, especially those related to economics. The accumulated domestic and foreign experience reflects years of intensive work carried out by scientists and engineers, which continues to this day. In Eastern Siberia and neighbouring regions characterised by a prolonged winter period, construction works are carried out all year round. Special attention should be paid to planning construction activities in winter and developing working documentation in view of the seasonality of work. The material and technical resources of the construction contractor should be taken into account, mainly the feasibility of the operational plans for construction and installation activities and the financing schedule. The paper includes examples of winter construction demonstrating the existing limitations, in particular the increased energy consumption. Some recommendations are given aimed at improving the quality of project documentation.
