ESTIMATED EVALUATION OF ALTERNATIVE ENGINEERING CONSTRUCTION TECHNOLOGY IN DENSE URBAN AREAS

The process of construction works in terms of building renovation or new construction is associated with a number of features of urban development. The dominant feature is the lack of facilities. This factor is a consequence of the economic interest of investors to develop most fully allocated in the city land. Special attention to this factor focuses on the stage of development of projects of manufacture of works. In this regard, in the process of designing and engineering preparation of construction, it is necessary to conduct an informed analysis of the conditions and characteristics of construction. To date, scientific, design and construction organizations of Ukraine, Europe and USA already has considerable experience of successful implementation of even the most complex projects of construction and reconstruction in complex urban terrain. Created new advanced design and technological decisions on construction of objects, including for the protection of the land, developed the methods of calculation and numerical simulation of the behavior of the object being built and located in the zone of influence of existing objects, methods and means of monitoring. However, most of existing organizational and technological decisions relate only to the general principles of construction under these conditions. Lighting practical experience at specific sites may provide a basis for improvement of existing and development of new more efficient and cost-effective technological solutions for construction of buildings and structures. Decisions must, in the first place, to ensure safe working conditions, to be economically justified, based on the results of the preliminary comprehensive examination and technical diagnostics of building structures. This is very important when making urgent technological solutions in the construction of individual buildings, to assess the possibility of use of hoisting machines and other means of mechanization, which are based on or are in contact with existing designs, the choice of the sequence of installation works. Adopted organizational and technological decisions are subject to scrutiny and obligatory reflection in specially designed and duly approved design documentation. The article highlights the experience of alternative engineering technology building construction in the special conditions cramped. An example of the basis of organizational and technological scheme of construction works on the basis of calculations of the bearing capacity erected building structures for the purpose of using them for the disposal of construction cranes and other mechanisms. The presented variant of unconventional solutions provides a rational construction technology reduces the impact of cramped facility on the efficiency of construction works, increase economic efficiency. The variant allows you to implement the adopted organizational and technological solutions on similar projects.
