| Summary: | When performing zero-cycle works in Saint Petersburg, it is necessary to take into account the properties of soils of surface strata represented by late glacial and post-glacial lake and marine deposits that serve as the Foundation of shallow foundations - they contain most of the body of friction piles in pile foundations. The presence of a large number of different technologies for manufacturing piles often puts developers before a difficult choice, which must take into account many different factors – the design of the construction object, the specific engineering and geological conditions of the construction site and of course the cost of the work performed. For many new technologies, the regulatory and technical framework is still insufficient. Their information provision is also lagging behind. Developers and investors sometimes do not know the advantages and disadvantages of a particular technology for making piles and the limits of their applicability, often stopping at the cheapest offers that do not always ensure the reliability of the future foundation.
