The article assesses the economic situation in the Far East and identifies the problems of effective development of the territory. The article considers construction technologies and engineering solutions that can be used by the participants of the state program "Far Eastern hectare" for the effective use of land. The territory of the Far East has been divided into regions that are relatively homogeneous in terms of natural and climatic conditions (the Republic of Sakha (Yakutia), Khabarovsk and Primorsky Territories), and optimal technologies for low-rise construction, technological solutions in terms of the device of autonomous heating and an autonomous solar power station for the designated areas are proposed.

Keywords: construction, low-rise construction, the Far East, "Far Eastern hectare", thermal efficiency unit, SIP panels, energy efficiency, "green" construction, construction 3-D printer, sandwich panels

Blasting operations are often the only way to prepare the material for the recess for laying roads and railways in the rocks. Explosive loosening is also used to extract stone as a building material. Field testing is costly and often dangerous. Therefore, it is necessary to first conduct a series of experiments on the model and find out the conditions for ensuring good quality loosening of rocks. In order for the results of model tests to be transferred to nature, a similarity between model and specimen is required. The approximate similarity is achieved by the equality of the similarity criteria for the model and specimen. The characteristic similarity criteria are obtained by analyzing the physical quantities inherent in a mechanical system using the theory of dimension and similarity. The received criteria are presented in the classical form. These are the criteria of Strouhal, Froude, Cauchy and Newton.
