摘要:To optimize the organizational and technological model of construction of buildings and structures in a dense urban environment, it is necessary to take into account the factors that have a destabilizing effect on the process of construction and installation works, and arising from the very definition of " constrained urban development", which involves getting near buildings, structures and linearly extended objects in the zone of influence of new construction or reconstruction. This article highlights a number of destabilizing factors that most strongly affect the time and economic costs that must be considered when developing a construction project.
