ECONOMIC AND ENVIRONMENTAL ASSESSMENT OF THE CHOICE OF PLANNING AND ENGINEERING PREPARATION OF TERRITORIES FOR CONSTRUCTION

Due to the fact that the process of urban engineering of territories includes procedures for socio-economic and engineering-economic assessment of the planning decision of the territory, there is a need to develop appropriate methods. Common for comparing different areas for construction and engineering preparation of the territory should be considered the amount of costs, consisting of the cost of different types of work to compensate for loss to the stability of the territory, as well as the cost of special studies to identify potential ways to reduce damage and engineering preparation and engineering protection of territory being developed or reconstructed. Damage assessment can be carried out based on the specific location of the territory (a certain part of the site) and landscaping of this area, with due regard for the types of buildings. The inclusion of procedures for the socio-economic and engineering-economic assessment of the planning decision of the territory in the process of urban engineering is justified. The dependences of the total values of losses in case of loss of stability of the territory depending on the type of object are established. Separately, the cost of measures for the engineering preparation of the territory depending on the angle of inclination of the relief was determined. An environmental assessment of the choice of planning option and engineering preparation of the building area is carried out. The largest share in the structure of economic losses from the possible activation of destructive processes in the soil brings housing – about 60% – so special attention in the analysis of anthropogenic impacts on the stability of territories should be paid to anthropogenic factors arising development of housing. The cost of engineering training measures is determined by the capacity of the soil layer, which loses stability, the capacity of the groundwater flow and the angle of inclination of the sliding surface of landslides in unstable areas of housing. To determine the degree of increase in the stability of the territory per unit of costs, it is necessary to take into account both simultaneous and current costs to be developed. Of all the possible options for stabilization measures, the best is the one that, under equal conditions, provides a minimum of reduced costs.
