The aim of this work is the instrument-aided structural survey to recover the operability of a five-storey brick building on a pile foundation after significant deformation. Methodology: The MicroFe software is used to simulate the stress-strain state of the building and develop the base–foundation–building system model. Research findings: During both construction and operation of the building, its spatial stiffness is disturbed with the crack formation in brick walls due to insufficient pile installation, i.e., the pebble-gravel layer is not reached owing to difficult engineering and geological conditions. Practical implications: The obtained results are used to develop recommendations to ensure the required spatial stiffness of the building by the outer wall reinforcement with strained steel bars locating at the level of intermediate floors.
