The Rajdhani Unnayan Katripakkha (RAJUK) and two city corporations in Dhaka were asked to find out the reasons behind the tilting of eight buildings in the capital during the tremors on April 25-26.
They were also asked to assess the extent of damage, fix responsibilities and submit a report to the government by May 20.
The instructions were given at a meeting of the National Earthquake Preparedness and Awareness Committee held on Thursday at the Secretariat with Disaster Management and Relief Minister Mofazzal Hossain Chowdhury Maya in the chair.
Disaster Management Secretary Md Shah Kamal and high officials of other ministries and divisions and authorities concerned also attended the meeting.
The Minister also asked the RAJUK and the city corporations to identify the risky buildings in Dhaka and mark them with special colours.
In the meeting, the authorities concerned informed that at least eight high-rise buildings tilted in Dhaka during the earthquakes that jolted the country on April 25 and 26.
The tremors originated in Nepal where death toll passed over 5,000 and thousands of people still remained missing.
Expressing dissatisfaction over negligence to the responsibility of finding out the reasons behind the tilting of the buildings, Maya asked the authorities of the two city corporations to look into it immediately and assess the extent of the damage.
The government will take further steps according to the report and its recommendations, he said.
Ministry's Public Relations Officer Omar Faruque Dewan told The Daily Observer that the RAJUK informed the meeting that the 'Building Construction Act (Building Code)' would be finalised by next September. Then it will be sent to the Cabinet for its approval.
The meeting also emphasised completion of the retrofitting works of older buildings of the Dhaka Medical College Hospital (DMCH) and other organisations.
The authorities concerned of different educational institutions, mosque and worships and markets were requested to test the capacity of their buildings immediately to avoid any destruction from such disasters.
