The introduction of modernized (improved) and new technologies is necessary to improve the quality of construction with a reasonable reduction in costs and terms of block-complete construction (BCS). There are various BCS technologies that combine known and developed methods and methods. Therefore, in order to increase the efficiency of construction, it is necessary to solve a number of tasks: to calculate the enclosing structures at BCS in accordance with their requirements for thermal

... on, to determine the economic feasibility of the measures under consideration. On the example of a research object, the choice of enclosing structures is presented in order to reduce capital costs. If the tasks are successfully solved, it will be possible to offer the restoration of objects destroyed by natural disasters, BCS of new buildings, as well as during the reconstruction of objects. The article presents: the object of research "Compressor station in the area of BPS-2 X field"; block buildings located on the site of the booster pump station are considered; the characteristics of the enclosing structures of the "sandwich" type with various heaters are given; their thermal engineering calculation and comparative analysis of the efficiency of the heat-insulating material were carried out. Conclusions, methods and ways of solving BCS problems are presented; modernization of construction technologies.
