RVA & PRIORITIZATION FOR SEISMIC RISK REDUCTION OF INFRASTRUCTURE
COUNTRY: Mindanao & Siargao Island, Philippines
CLIENT: The World Bank Group
COMPANY’S ROLE: See lateral description

The objective of the World Bank assistance is to support the regional and provincial governments in their capacity to implement ex-ante seismic risk reduction evaluations in the area affected by the earthquake. In this regard, the Bank deployed a team to undertake a rapid visual evaluation of a sample of public buildings in the Province.
The specific objectives of this assignment are to:
i. conduct Rapid Visual Assessment (RVA) of selected public buildings in the earthquake-affected area with a prioritization of the most vulnerable to seismic hazard;
ii. based on the RVA, provide risk reduction options (retrofitting/strengthening measures) for the assessed buildings, and the corresponding rough cost estimates.
RVA covered 31 buildings on Mindanao Island and 8 buildings in Siargao Island. The pre-earthquake inspection surveys are based on the FEMA-154 Rapid Visual Screening of Structures for Potential Seismic Hazards. These instruments, developed in the United States and adopted worldwide, have been adapted locally in order to consider the local conditions of structures exhibiting different seismic capacity compared to the US buildings stock.
Based on the findings of the previous task, the consultant supported the Government in developing the priority list of public buildings for seismic retrofitting/strengthening and developed a preliminary cost estimates to provide the Government with a budget estimate for the proposed retrofitting or strengthening options for the most vulnerable buildings.
