The purpose of the study was to find methods to reduce the construction time of special purpose structures. The analysis of the factors influencing the terms of construction of nuclear power plants is carried out. Using the example of calculating the parameters of the ventilation pipe installation of a really erected nuclear power plant, the advantages of replacing the traditionally used for the construction of these structures with the method of "falling arrows" are noted.

The aim of the study was to identify the optimal choice of the set of leading machines according to the ratio of such parameters as "Time" and "Cost." Within the framework of the study, the scheme of selection of the set of machines in accordance with geotechnical and production conditions of the construction area and economic conditions of the potential customer was determined, as well as a table of selection of machines depending on the initial parameters was drawn up.
