Modern construction should be of high quality and economical. The construction of buildings and structures must be carried out in a short time. Often, in pursuit of speed and optimization, developers adopt modern technologies, not always assessing the risks associated with them. As a result, this can lead to a decrease in the quality of the object being built. The technology of producing piles “Fundex” is one of the most common in St. Petersburg. The simplicity of this technology makes it possible to produce up to 10 piles per shift. However, this technology has a number of disadvantages, including: possible problems when concreting, a significant zone of influence on the stress-strain state (VAT) of the base. This paper considers one of the most important aspects of the production of these piles: the impact on the surrounding development and previously manufactured structures. In the course of constructing two pile fields, totaling 1,711 piles with a diameter of 520 mm and a length of 28.2 m, the changes in the planned and high-rise position of five buildings of the surrounding development, the previously completed underground part of the building under construction, as well as deformations of structures enclosing the future pit were monitored. Various measures aimed at reducing the negative impact of the construction of “Fundex” piles were tested and their effectiveness was evaluated. Based on the observation made, practical recommendations for the use of this technology are given.
