High-rise construction is an urgent way of development of modern megacities in conditions of constant growth of the urban population and the accompanying shortage of land for the construction of residential and civil facilities. At the same time it is necessary to preserve the urban planning herit-age, which forms the individual character of the city. On the one hand it is necessary to orient to his-torical and cultural peculiarities of urban environment and available urban resources, on the other hand it is necessary to strive for individual architectural and urban solutions that would make the high-rise buildings under construction attractive for investors as well as for the urban appearance of the city and attract tourists. However, for the realization of creative ideas in the construction of high-rise buildings is necessary to search for adequate technological solutions, which is often a difficult task, especially in conditions of dense urban development.
The objective of the article is substantiation of organizational and technological solutions for high-rise construction under the conditions of dense urban development.
The analysis of experience in the construction of high-rise buildings has been carried out and substan-tiation of organizational and technological solutions of high-rise construction under the conditions of dense urban building has been provided in the paper.
On the basis of the conducted research there has been shown a possibility of increasing the efficiency of high-rise building management by means of improving the method of substantiation and selection of rational organizational and technological solutions of high-rise building construction, aimed at ef-fective use of resources and reduction of the cost of construction output due to taking into account the urban planning value of territories and the complex influence of energy saving and environmental fac-tors. At the same time the study results showed that during the construction of high-rise buildings with a developed underground part in the conditions of dense urban development it is necessary to solve a number of complex technical problems associated with technological features of construction and en-suring the stability of the existing building. Nevertheless, modern construction technologies and equipment make it possible to carry out a choice of available methods of construction of high-rise buildings with underground structures, for example, the technology "up - down", which makes it pos-sible to carry out work on the underground and aboveground parts of the building almost simultane-ously and thus accelerates construction time of buildings, especially high-rise and high-rise.
The results of the study can be used in the practice of high-rise construction in dense urban develop-ment.
