Research of buildings in permanent frost area shown that using of the I principle of building is an acceptable way to secure constructions. The high pilework is common and an acceptable way of realization of the I principle. Besides, high pilework make functions of seismic isolation. Researchings of buildings with high pilework in 7, 8, 9 point seismic areas show that increasing of «free» length of pile increase period of oscillations. This decrease seismic load, but increase square of reinforcement. Acceptable section for 7-point area is 40x40 cm for reinforced piles. In higher than 7-point areas using other different constructions of piles or dampers is required.
