Project Description:

In recent years, Bangladesh has reformed its approach to natural disastrous events like cyclones and floods. The threat of an earthquake, however, is less visible but significant given that Bangladesh lies on the seismically active zone of the Indian plate.

The main objective of the Project was to assess the vulnerability and risk of Dhaka’s critical facilities and develop a prioritized investment plan through an analytical approach. Consequently, the main outputs of the Project were as follows:

1. A Long-Term Vulnerability Reduction Investment Plan, and
2. The Dhaka Urban Resilience Strategy.

The Project was organized in 3 stages and included the following assignments:

• Data Collection
• Rapid Visual Assessment (RVA) of roughly 5 million square meters of critical public assets
• Preliminary Engineering Analysis (PEA) on the prioritized buildings in the previous step
• Detailed Engineering Analysis (DEA) on the prioritized buildings in the previous step
• Preparation of the Long-Term Vulnerability Reduction Investment Plan and the Dhaka Urban Resilience Strategy.
• Performing Capacity Building.

Service Provided:

The main tasks of the project were as follows:

Task 1. Conducting Rapid Visual Screening/Assessment of 3252 public facilities including schools, hospitals, universities, fire stations, and police stations; encompassing 5,382,000 square meters; and submitting complete reports on the findings of all the buildings/facilities that have been assessed with prioritization ranking of each building in terms of vulnerability and risk.

The main activities and deliverables were as follows:

• Data collection from engineering and architectural perspective
• Risk assessment of structural and non-structural components
• Risk identification and vulnerability scoring of all the structures
• Prioritizing the most critical facilities among them up to a level of 20%
• Comprehensive report on the outcomes of the Rapid Visual Assessment (RVA)

Task 2. Preliminary Engineering Assessment using internationally recognized methodologies tailored to the project case for the most critical facilities identified during the rapid visual assessment with approximately 1 million square meters built-up area (Approximately 600 schools and hospital buildings).

The main activities and deliverables were as follows:

• Architectural and structural surveying of the structures
• Destructive and non-destructive testing to verify the material characteristics and strength.
• Retrofitting schemes to overcome the associated vulnerabilities
• Preliminary cost estimate for the feasibility of the structures to go for retrofitting
• Prioritizing the most critical facilities among them up to a level of 40%
• Individual final reports for each structure analyzed
• Retrofitting and rehabilitation designs including Energy Efficiency designs
• The synthesis reports

Task 3. Detailed engineering assessment using internationally recognized methodologies tailored to the project case for the most critical facilities – 200 facilities with more than 400,000 sqm of built-up areas.

The main deliverables were as follows:

• Material test report covering soil investigations, geotechnical and geophysical studies, surveying, concrete core sampling and exposure of the steel, ferro-scan readings along with all the architectural, structural, mechanical, and electrical findings and information gathered through foundation pit openings.
• Assessment findings and methodologies
• Approval documents from the principals and directorates
• Preliminary structural and non-structural analysis, calculations, and designs for different retrofitting alternatives and recommendations including structural, architectural, mechanical, and electrical findings
• Cost and cost comparison estimates
• Final design report and drawings including detailed structural retrofitting design, detailed non-structural retrofitting designs, and detailed architectural, mechanical, and electrical designs
• Final costs and cost comparison for alternatives
• Tender documents and bill of quantities.
