Abstract Solving the problem of rational use of building materials in the development of new fields helps to minimize ineffective consumption of applied resources. The purpose of the conducted research was to develop recommendations on the selection of rational parameters of drilling piles for engineering structures constructed on soils of the Chayandinskoye oil and gas condensate field. Bearing capacity of a base of a vertically loaded friction pile was calculated by means of existing methods. Selection of specific bearing capacity as a target parameter characterizing the efficiency of building materials and bearing capacity enabled to give a comprehensive estimate of influence of structural parameters and natural factors on bearing capacity of bored piles in a foundation soil. A complex nature of pile geometric characteristics and ground conditions’ influence on the target parameter was established during theoretical calculations. For geotechnical conditions of the Chayandinskoye oil and gas condensate field, it was established that the use of piles with a bigger diameter of 0.4-0.5 m and the length of 6 m in soils with a temperature of no more than -2.0 °C and an ice content of no more than 0.2 is rational. Practical recommendations to use the results obtained during the performed studies can reduce inefficient costs of not only material, but energy and time resources in conditions of remote industrial facilities and logistics bases.
