THE REGISTRATION OF UNCERTAINTY AT THE TECHNICAL AND ECONOMIC SUBSTANTIATION ON DESIGN DECISIONS OF CONSTRUCTION OF HIGH-RISE MULTIFUNCTIONAL COMPLEXES

The design decision represents the description or an assessment of a designed project sufficient for consideration and taking of the conclusion about the end of design or ways of its achievement. The feasibility study on design solutions of construction of facilities assumes determination of cost and duration of their construction. When developing the feasibility study it is necessary to recognize that the construction cost coordinated with contract organization, provided in the approved feasibility study, is a limit for the entire period of design and construction. Preliminary development of the feasibility study is an indispensable condition of the tender. Today in the large cities of Ukraine is more actively carried out process of design and construction of high-rise multipurpose complexes, despite difficult architectural, space-planning, constructive and organizational and technological solutions that is caused by deficiency of the free land plots and their high cost, and, as a result, need of the most effective use of the territory, increase of consumer requirements to quality, comfort and safety of objects. However so far there is no exhaustive scientific justification predicted costs and durations of high-rise construction though these indicators are defining when carrying out the contract auction. For a possibility of adoption of the most rational design and organizational and technological solutions of construction of high-rise multipurpose complexes at systematization of factors which influence process of decision-making and further implementation of the project, for a choice of the better decision uncertainty should consider when carrying out system researches. It will allow to determine the specific weight of influence on result of each of the considered factors with a bigger accuracy. Purpose. Consideration of influence of fundamental and utilitarian uncertainty to the studied processes of construction of high-rise multipurpose complexes. Conclusion. Understanding and registration for potential uncertainties in conducting of analytical research in the field of planning of construction of high-rise multipurpose complexes will significantly improve their effectiveness.
