description: This paper presents the design documentation for a public building in St. Petersburg, as well as evaluates the relevance of using the "Top-Down" method when arranging recessed parts of buildings erected within the boundaries of the central district of St. Petersburg. The analysis was carried out by the method of software modeling using software - Plaxis 2D. The tasks that were solved during the study: 1. Development of design documentation for a public building in accordance with the Decree of the Government of the Russian Federation No. 87 "On the composition of sections of design documentation and requirements for their content"; 2. Review of the principle of work performance when implementing the "Top-Down" method; 3. Analysis of the geological situation within the central region of the city of St. Petersburg; 4. Software modeling and comparison of two methods of constructing the underground part of structures: by the method of open excavation of a pit with a wall in the ground and by the âTop-Downâ method. On the basis of the studies carried out, the âTop-Downâ method was chosen as the optimal one to ensure the lowest settlement of the surrounding buildings when constructing underground parts of structures in the central region of St. Petersburg.
