Currently, a number of difficulties arise in the construction of dense urban areas, as well as in the reconstruction and superstructure of existing buildings and structures. Often when carrying out geological scene investigation, it is not possible to determine the strength parameters of the soil directly under the foundation. In most cases, this leads to understating of its characteristics, which is reflecting in the excessive economic costs resulting from the need to strengthen the existing building structure. However, in many situations, this can be discarded, justifying it by calculations. In this paper is shows the performed series of numerical experiments and were analyzed the changes of existing building foundation settlements, taking into account its long-term exploitation in assessing the impact of new construction. The base had defined by a single-layer half-space with a limited depth of deformation zone and composed of medium-sized sand. PLAXIS 2D software was chosen to create the calculation model. When processing the results, it was possible to identify a certain dependence that allows estimating the maximum settlement of existing building in the impact assessing from new construction taking into account the duration of building operation. The obtained data prove the necessity to take into account the change in strength properties of soils caused by long-term loads action of structures.
