The work is a continuation of the study of cable-stayed roofs of large-span sports buildings, it focuses on the technological aspect of the construction of stadiums and sports palaces. Due to the introduced criterion of the location of the assembly of structures, the systematization of technologies for the construction of facilities currently commissioned has been carried out. The result of the work is a comparative table that allows to rationalize the choice of methods of pre-assembly and installation.

Modern construction industry is actively introducing new technologies and innovations in the field of high-rise buildings. This dictates certain requirements for the architectural and design features of the frameworks of buildings and the strengthening of foundations. It is necessary to give sufficient rigidity to the object in order to withstand external loads and impacts. All activities are aimed at ensuring the safety of people staying in a high-rise building. In recent decades, the construction of skyscrapers has increased, and such a notion as progressive collapse has become relevant. Therefore, the article examines and analyzes exactly progressive collapse as a problem requiring attention and a scientific approach to its elimination. The report concludes with some conclusions and recommendations.
