RVDAThe M7.8 Nepal Earthquake of April 25, 2015 struck at 11:56: NST, with its epicenter located at 28.147°N 84.708°E in Gorkha Area of Nepal, at a shallow focal depth of 15.0 km. The unfortunate event killed more than 8000 people and injured more than 15000 populations. Further the earthquake cause damage to more than 300000 structures in the country.

The official of the Center of Resilient Development (CoRD) undertook a rapid damage assessment of the affected buildings through mobilization of its resources and staffs. The houses/buildings have been generally categorized after inspection into 3 categories i.e safe to use, use with certain restrictions and unsafe to use. The assessment has been carried out by trained Civil/Structural Engineer. The report is prepared on the basis of rapid visual assessment survey carried out by Civil/Structural Engineer aftermath of the April 25 earthquake. DUDBC Guideline /ATC 20 form has been used for the assessment and onsite counseling and advice were given to the building occupants.

Methodology Of RVDA

Graduate Civil Engineers along with professional from structural engineering background and geotechnical backgrounds have been mobilized as surveyor. The selected surveyors were oriented and trained for carrying out assessment using Rapid Evaluation Form from the MoPPW publication “Seismic Vulnerability Evaluation Guideline for Private and Public Buildings” / ATC-20 Evaluation Safety Assessment form. After 4 hours of orientation trainings, the engineers were taken to the field where onsite discussion and data collections were discussed with the participants. Only after this, the engineer was sent to field for the assessment. A group of experts from Structural Engineering, Geotech Engineering and Architectural background were stationed in the office to provide supports to the engineer in the field through mobile communications. Further, in the evening when they returned back, an interaction was organized to discuss the nature of failure, problems of surveyors and expert opinion on their observations. If necessary, the house owners were contacted for specific advice. The data collected were tabulated and an initial report has been prepared with preliminary analysis.
