Abstract: In this study, the educational building fall on natural slopes in the Kinnaur region, where the stability of buildings seems to be compromised by certain damages and settlement. Geotechnical analysis was carried out to determine the inherent soil properties that affect the study area. Stability check (FoS) was calculated by using software and applying Bishop's method of stability analysis for static situations. The study area was divided into three sections; under natural conditions, FoS is found to be in the range of 0.52-0.65. After applying the remedies, the FoS of the stable sections were 1.59, 1.99, and 1.58, respectively. As a direct consequence of this, various adjustments and preventative measures have been proposed.
