Mongolia is landlocked country located between Russia and China. The climate of Mongolia is characterized by arid and semi-arid conditions. The aim of this study is to determine the engineering geological condition based on the soil properties at the construction site of tourism conmplex where located in Khan-Uul disctirct, the southwestern part of Ulaanbaatar city. In the study area, a total of 34 boreholes were drilled in May 2024. The borehole depths range 10-20 m. A total of 139 unbroken soil samples were collected to define the physical and mechanical properties of soils. The soil in the study area were classified into four engineering geological elements based on the results of laboratory analysis. The depth of seasonal freezing varies depending on soil type, ranging from 2.78 to 3.97 m. The study area was determined to have moderate engineering geological conditions based on the physical and mechanical parameters of soil.
