RECONSTRUCTION OF HIGH-RISE BUILDINGS AND FACILITIES

Modern tendency of architecture for development in densely populated cities in Ukraine is closely related to the increase in building height, this is due to the density of urban development, land prices and the ambitions of architects, but the experience of high-rise buildings identified by the SCN V.2.2-24: 2009 as tall buildings from 73,5 m to 100 m inclusive, is small enough that leads to defects and errors in the design - hence determines the relevance of the criteria for determining the complex dismantling and installation work on the reconstruction of buildings of this class. Tall buildings and facilities designed to meet the domestic, industrial and cultural needs of the people. In this regard, you must constantly take care of their preservation during their entire life cycle, consisting of technically correct operation and maintenance. The performance of high-rise buildings can be enhanced through a major overhaul and reconstruction performance. The aim is to improve the reconstruction or modification of functional, structural and aesthetic properties of buildings with a comprehensive view of social and urban problems, as well as economic and technical efficiency of its implementation. When reconstruction is often a need in the superstructure, strengthening the individual designs, eyeliner foundations, and in some cases, shifting buildings. This work is often carried out in cramped conditions, making it difficult to storage of materials, the use of lifting devices, increases the demands on safety, increases the cost and duration of the works. The main factors to reduce the cost is to decide on the basis of well feasibility studies on the choice of working procedures, the use of modern production technology and a clear, coordinated organization of workers [1; 4]. Purpose. Defining criteria for dismantling and installation of construction work on the reconstruction of high-rise buildings and structures in high external constraint. Conclusions. Question reconstruction of tall buildings seem not so sharp due to the weak development of the construction of high-rise buildings themselves, demonstrates this and the lack of literature on this topic, including a relatively young regulatory baza. The time of writing in Ukraine put into operation a total of about 10 buildings, stepped 100 m mark, but these buildings enough to commemorate the arrival of the era of high-rise construction and stimulate the development of the regulatory framework and the literature devoted to the construction so as to further remodeling of the whole class to the reconstruction of high-rise buildings similar to the reconstruction of buildings and other structures, apply similar steps in the preparation of the package design and estimate documentation, preceding and accompanying works, unlike most directly on the selection and the further application of organizational decisions, namely the choice of mechanization schemes dismantling and assembly works of reconstruction, especially storing and organizing the transport of materials. Carrying out work in conditions of reduced external and internal, is likely to continue operation of the building also imposes a number of restrictions on the timing of the works, and requires careful consideration of all the organizational and technical issues for the reconstruction work.
