The article defines and compares the obtained sediments based on the results of applying the current regulatory methodology of the set of rules 22.13330.2016 "Foundations of buildings and structures" and numerical calculations using various models of the soil base implemented in the SCAD office software package, using the example of a frame-monolithic building of the residential complex which is called "Novaya zhizn" in Belgorod. A brief overview of methods for joint calculation of the foundation and aboveground parts using various models of the ground base: Pasternak with two bed coefficients, variable area bed coefficients in the sattilite CROSS program and the model of linear deformable half – space implemented in SP 22.13330.2016. Analytical calculation of the sediment value for set of rules 22.13330.2016 is performed "manually" by the method of layer-by-layer summation. The numerical calculation of the frame-monolithic building is performed as a single system "building-foundation – base". The values of sediments and bed coefficients C1 and C2 based on the results of numerical calculation are presented in the form of graphical isofields of displacements and bed coefficients. Based on the results of analytical and numerical calculations, the main conclusions are made and recommendations were presented on the applicability of each of the considered models of soil bases
