Most parts of the Indian Himalayan region are susceptible to severe earthquake shaking. Non-engineered construction practices in this region, due to lack of awareness/negligence of the stakeholders, are prevalent which may lead to disastrous consequences during any seismic event. For ensuring uninterrupted public services post-earthquake, it is utmost important to perform seismic vulnerability assessment of important buildings in this region to understand their expected performance during an earthquake. To conduct seismic vulnerability assessment of buildings at large, rapid visual screening (RVS) can be opted as a tool to quickly segregate them based on their expected performance. In this study, RVS of 108 important buildings (hospitals, educational institutes, and government offices) is performed in Mandi district of Himachal Pradesh, India. The observed building typologies for the important buildings and various vulnerability attributes in those buildings are presented here. Further, the surveyed important buildings are assessed based on different structural irregularities using three different RVS methods and it is observed that most of the surveyed buildings require detailed vulnerability assessment.
