Engineering preparation of the territory for the construction and development of a residential complex is a difficult task. In the development area, fluctuations in the groundwater level are possible due to natural processes - flooding of the territory or during operation due to man-made processes. The work presents the results of the survey and assesses the impact of future construction on the hydrological situation of the built-up areas. Materials from engineering-geological surveys of the composition of soils in the lake water area and the building area were studied in order to determine the possibility of using alluvial soil from the lake for engineering preparation of the territory.

In order to speed up consolidation, vertical drainage has proven to be a good option for the construction of modified bases . A set of experimental field studies was conducted to study the influence of self-forming vertical sand drains on the process of consolidation of water -saturated soil. Experimental equipment for the construction of vertical sand drains for work in Western Siberia has been developed.
