The long-running building on clay soils with a life span of more than 25 years foundations sediments are considered. In the immediate vicinity of the building under consideration, the new neighboring building construction was completed at a distance of 6 m in light. The foundations of the long-used building are tape from monolithic reinforced concrete, and the new neighboring building in the monolithic reinforced concrete slab form. Both buildings foundations are arranged at the same mark. The foundation soils are represented by two engineering-geological elements: from the surface - soft plastic loam (EGE-1) 10 m thick, then - semi-solid clay (EGE-2) more than 12 m thick. The foundations bearing layer is soft plastic loam (EGE-1). The calculation revealed the long-term operated building strip foundation additional precipitations from pressure on the foundation transmitted by the new neighboring building. To reduce the additional sediment foundations considered options for the dividing wall structural solutions (different bending stiffness EI) between buildings. The buildings foundations sediment numerical calculations and their increments are made in the Midas GTS NX software package; given the results assessment.
