The development of a sports hall in the Unika Soegijapranata Campus in Central Java is constrained by geological conditions. At the time of land preparation, a crack appears on the fence of the sports hall foundation that was predicted as a sign that they have a soil creep. This condition has threatened the implementation of such development. Therefore, it is necessary to know the subsurface conditions, especially the sliding surface location and pattern of the existing cracks in the ground. This information is beneficial to avoid soil creep risk. In order to support the information, both the geological survey and seismic refraction were conducted in this location. According to the survey, it is found that the sliding surface was identified as volcanic breccia with the depth from 5 m up to 20 m. There are many faults found based on the seismic data, and many cracks appear on the surface, which suspected as the creep crown. Some areas of the sports hall are located in the soil creep crown. According to the drilling data and geo-electrical survey, the sliding surface location of the soil creep was identified within volcanic breccia layers. It is recommended to shift the planned location of the sports hall in order to avoid or minimize the soil creep risk.
