Environmental impact of long-term construction objects on urban systems

The significance of unfinished building object as elements of urban systems of modern Russian cities is shown. The existence of these objects can impact on urban environment conditions at a significant distance from the places where they are located. The urban environment is considered as a dynamically developing urban system, which includes a combination of potential-controlled natural and technical systems. The appearance of areas of uncontrolled environmental degradation around objects under incomplete construction reduces the level of comfort of urban environment.
The main types of incomplete objects under construction and their impact on the environment are given. The article is based on observations of the state of more than 30 objects under construction and on the results of studies of environmental processes at the areas where they are located. The classification of objects under construction is proposed. The classification takes into account the stages of destruction of objects under construction and related environmental impacts. The need for a integrated hazard assessment of long-term construction objects as unmanageable degrading natural and technical systems is justified.
