Bangladesh and Dhaka
BangladeshArea = 147,570 sqkm Population = 162 MillionLocation = South AsiaGDP growth = 6%GNI = 923 USD (2012‐13)
DhakaArea = 1,528 sqkm Population = 18 MillionLocation = Central Bangladesh
88,000 people <1.3 %> will be killed (out of 7 million citizens)
Many & Various facilitieswill be damaged remarkably
Loss will be 25% of Annual National Budget
Government of Bangladesh has started to prepare future earthquakes
“First Step Towards Retrofitting” 22, June 2011
Options for solutionMost vulnerable (existing)
>> demolished and rebuilt (new)
Most important and vulnerable (existing)>> retrofitted
Newly construction (new)>> built following BNBC
CNCRP, 2011

Everyone knows and says “Buildings in Bangladesh are vulnerable”
butAlmost all people do not know
“How much they are weak quantitatively”

• Nations– Citizens, Families
– Students, pupils
– workers
• Owners– executives
– administrators
• Finance & Donors– National Bank
– City/Local Bank
– JICA, WB, etc.
• Engineers– Design (architecture, structure)– Design (Equipment, fire safety)– Construction, supervision– (public and private)
• Consultant, contractor– Design consultant– Construction contractor– Site workers(bar‐binder, mason)
• Government officers– MoHPW, LGED, EED
– Other ministries
– Building Officers,
organizations

• Option 2Enforce BNBC for new buildings, (with raising awareness)
• Option 3Retrofit existing important buildings (government and private)

Bangladesh Bank has started a fund by loan of Tk. 100 crore with assistance of JICAfor RMG sector
MOU signed among JICA, BB, BGMEA, BKMEA and PWD of MoHPW on October 3rd, 2013. 22

34.5% 65.5%
[Findings by Initial Assessment]36/55 (65.5%) Factories do NOT comply the standards set by Bangladesh National Building Code (BNBC)
How much finance is required for the entire RMG sector (including fire safety)?
3,000×65%×$600,000= $1.17 billion ?
300RMG factories
85RMG
factories
215 do not have necessary information for seismic assessment (71% cannot do assessment).
30 are not target buildings.

Retrofitting of Public Buildings
53 years oldTejgaon Fire Station
Dissemination to the Public of Building Disaster Awareness Raising
• School Disaster Management program
– 3 schools (~ 1000 students and guardians)
• Colony Residents CBDM Program with FSCD
& volunteers
– 3 colonies (Evacuation, Fire Safety & First Aid)
27
What to do next?• Continue CNCRP, and RMG project as well as Raising Awareness and following BNBC
• ProvideMethodology & Manuals for Bangladesh– Simplified and Detailed Evaluation–Retrofitting building Design–New building Design–Construction Management and –Quality Control
• Assist the basis forSafer Buildings and Resilient Cities
