Component 1: Multi-hazard Assessment, Vulnerability Analysis, and preparing the retrofit design for existing healthcare facilities

The latest post-disaster observations indicate that, even many Hospitals and Critical Urban Facilities which have been well-designed based on traditional regulations, have shown vulnerable, did not perform satisfactorily during the natural hazards and failed in continuation of providing services during crisis period.

Thus, as a major element of Disaster Risk Reduction and Management (DRRM), the objective of Component 1 in BEHTAB phase II project is shedding light on the vulnerability of existing Risk and provide the detailed knowledge about the vulnerability of the hospitals as critical facility inventory in urban areas against natural hazards. The Project also aims at Instructions for action on Risk Reduction and improving the resilience of the facilities through retrofit design for the vulnerable hospitals, upgrading the design methods for new hospitals, Development of designing retrofit methods for existing facilities.

Meanwhile the considering the resilience of the hospitals against earthquakes, the performance of the facility during the earthquake and continuation of the functions after the event has been taken as a major factor, resulting in the Performance-Based Design (PBD) approach identified as the best for the Project regarding the newly designed and building facilities vs. the traditional force-based methods which has been practiced in the expert communities before implementing this Project.

The Approach to the above Objectives is through a cooperation between UN-Habitat and EOGPBI for studies on vulnerability assessment and retrofit design for existing/under-construction public hospital facilities.


The Project was implemented in three steps for each hospital as:

Rapid Visual Assessment (RVA)More

Probabilistic Seismic Hazard Analysis (PSHA) More

Preliminary Engineering Analysis (PEA) More

Detailed Engineering Analysis (DEA) More


RVA, PEA and DEA studies were carried out by EOGPBI consultants in the field of hospital design and under the supervision of TWG members through review of reports and meetings with consultants. In this regard multiple sessions were held with consultants for presentation of their studies procedure and results to the TWG members as well as questions and ambiguities through question and answer sessions.

The main outputs of this component can be addressed as:

  • Determining the status of vulnerability of hospitals against natural hazards along with the need for retrofitting and detail design of retrofit methods for each facility of the 11 hospitals (with a capacity of over 4000 beds)
  • Knowledge sharing and capacity development in the partners (both public and private sectors) on DRRM and PBD for the public assets
  • Develop the institutional and expert required capacity for this transition.
