As a result of changes in regulatory documents on acceptance of residential premises, there is a need to develop illustrative methodological materials that would allow the future owner to independently, i.e. without the involvement of an external qualified specialist, to perform the acceptance of the apartment, pointing out to the representative of the developer involved in the acceptance of significant construction defects. The purpose of the study is to determine the structure of construction defects in residential premises and to identify the most common defects in this structure, which will allow the future owner to independently perform the acceptance of the apartment. In the article, based on the analysis of a significant number of claims from apartment owners to the builder and the results of the authors' research in the scope of forensic examinations and pre-trial construction-technical investigations, the structure of construction defects, which are massively identified in the process of acceptance of apartments, is defined and presented. The groups of defects that are most frequently encountered in practice are presented. To ensure the clarity of practical use of the obtained analytical materials, a list of mass construction defects identified in the process of acceptance of residential premises, indicating their category necessary for making a decision on the mandatory elimination of defects is defined.

Over the past 35 years, long-distance wells in Russia and the CIS countries have been drilled and blasted. The big disadvantage of this technology is the lack of the possibility of combining the most labor-consuming tunneling processes in the borehole bottom: drilling and blasting operations and rock removal. Because of this, the average rate of shaft construction did not exceed 30-50 m / month, which is 2-3 times lower than when driving horizontal and inclined workings.A promising direction for solving this problem is the widespread introduction of mechanized complexes of a new generation of domestic (SPKV, ASP) and foreign (Herrenknecht AG, etc.) production in deep hole drilling. However, their wider implementation is restrained by a number of undeveloped issues related to the justification of a rational field of application and parameters of an effective technology of shaft sinking with mechanized complexes.The article discusses the concept of a mechanized technology of shaft sinking with variable, technically and economically justified speeds, implemented within the framework of the flow organization of the construction of a complex of shafts. The main stages of designing the flow method are considered and an algorithm for determining the optimal speed of mechanized shaft sinking in various mining conditions is presented.
