The article proposes to consider the possibility of using pipes from ductile iron with spherical graphite in the construction of oil pipelines to solve the problem of corrosion formation. In addition to corrosion resistance, such pipes also have other positive properties. A comparison is made with steel pipes, and the basic physical and mechanical properties of ductile iron with spherical graphite are also considered.

The article is devoted to the question of the effectiveness of separate foundations. In particular, a specific version of the foundation with a modified geometry is considered - steps down. The foundation with a stepped sole has a greater bearing capacity and stability, as well as its device requires less labor, which makes it more efficient, analogs with a flat sole.

Keywords: foundation, construction, modified geometry, non-planar sole, soil mechanics, construction efficiency, earthworks, critical pressure
