method (FEM) was used. First, the initial state was generated. Next, the southern tunnel of the metro construction was simulated. Then, the northern tunnel of the metro construction numerical model was prepared. Based on this simulations and cumulative settlements of a particular building above the metro were calculated. The results were confirmed by land surveys. The calculations show the maximum vertical displacement of 8 mm below the building’s foundations. This value does not affect the stability of the building or the slope nearby. Nevertheless, it can impact serviceability. Such settlements can generate cracks in buildings. Furthermore, the value of the calculated safety factor of the Warsaw Slope in this section is 1.1. Hence, slope changes require continuous observations. The numerical procedures presented show the usefulness of FEM and its suitability for the purposes of building an extension of the 2 metro line.
