Under the basement of another four -story building in the fall, a pit was dug in a dry small sand with an admixture of 15% of clay at a pressure of 2 kg/cm2. The removal of surface water from the pit was not done. In mid -April of next year, a bottle laying of the foundation was launched with preliminary removal of the upper layer of frozen soil. In early May, to the paddock, it was suspended due to the cracks discovered in it, although it was erected to a height of only 0.5 — 1.5 m.
