The article describes the methodology for automating the design process of pile foundations using the Svaya-SAPR Pro software. The proposed method of automating the design process makes it possible to perform calculations and select optimal solutions for pile foundations. The application of Svaya-SAPR Pro reduces the complexity and timing of design, reduces the risk of errors when performing a large number of calculations. When performing a technical and economic comparison of options for the implementation of pile foundations, Svaya-SAPR Pro allows to reduce the cost of infrastructure projects. The article presents the features of calculations of pile foundations in frozen soils, which were not included in the official edition of SP 25.13330.2020 and presented by the N.M. Gersevanov Research Institute in the framework of the technical expertise of the local regulatory document Rosneft Oil Company, which was named "Design features of pile foundations". The technology was developed in a subsidiary of Rosneft Oil Company - NK Rosneft - NTC LLC and entered into a single line of the Company's software. «Svaya-SAPR Pro» application based on the test results was recommended by the N.M. Gersevanov Research Institute for performing calculations of foundations and pile foundations according to SP 24.13330.2021 and SP 25.13330.2020. The method presented in the article for optimizing capital costs using the Svaya-SAPR Pro software allows to select the most cost-effective technical solution for each pile in an automated mode, as well as to reduce capital costs by up to 15% of the cost of the projected foundations and up to 20% of the labor costs for design without reducing the mechanical reliability of the projected objects.
