A feature of modern construction is the large-scale reconstruction of blocks in the center of large cities. In recent decades, investors have increasingly sought to increase the number of storeys of buildings. However, the construction of high-rise buildings (above 75 m) in the conditions of the current development of the metropolis has a number of problems that can negate all the benefits of placing a real estate object in the central districts of the city. The greatest problems are identified already at the design stage of the foundations of high-rise buildings. The article discusses 5 key problems that have the maximum impact on the increase in the cost of construction of high-rise buildings.
Keywords: high-rise buildings, the conditions of the existing development of the metropolis, engineering and geological surveys, dense urban development, geotechnical forecast, geotechnical monitoring, excavation, pile foundations
Engineering and geological conditions of the reconstructed territories are important town-regulating factors in the development of Master Plans and Rules of land use and development. They should be taken into account both at the pre-investment stage and at the stages of development of preliminary and working projects of construction projects. Data on the degree of exposure to dangerous engineering and geological processes will allow calculating the stress-strain state of the foundation depending on changes in the physical and mechanical properties of the soil, which means making the most effective organizational and technological decisions for the reconstruction of urban development.
