Speakers at a seminar Sunday said no building collapsed without showing any signal, even Rana Plaza gave the signal two days before its collapse.
If the signal is ignored, then heavy damage is inevitable. Quick steps should be taken without wasting time after getting the signal, they said.
The speakers made the observations at the seminar titled “Building Safety Assessment,” jointly organised by the leading cement producer of the country, Bashundhara Cement, and the Civil Engineering Department of the Bangladesh University of Engineering and Technology (BUET), at the Academic Council Bhaban of BUET.
Nowadays, building safety assessment is being done by creating awareness after the Rana Plaza tragedy, they said.
Engineer Mohammad Shahidullah said, “Every building gives signal at least one day before its collapse. The signal should not be ignored. If you ignore the signal, damage will be like that of Rana Plaza.”
If proper steps would have been taken quickly, then many lives could be saved, he said. He asked for taking proper steps after getting the danger signal without wasting time.
Prof Dr Md Mujibur Rahman, chairman of Civil Engineering Department of BUET, chaired the seminar while Engineer Mohammad Shahidullah was present as the special guest.
Dr Ahsanul Kabir, Professor of Civil Engineering Department of BUET, presented a keynote paper on “Safety Assessment Procedure for Existing Building: Bangladesh Context.”
Earlier, building safety assessment was rarely taken in Bangladesh but nowadays some people or organisations are doing building safety assessment as per requirement of the RMG buyers or as per directive of the government, he observed.
Dr Mehedi Ahmed Ansary, Professor of Civil Engineering Department of BUET, presented another paper on “Equipment Required to Carry out Detailed Investigation of Factory Building.”
In his presentation, Ansary showed how some instruments including Terrestrial Laser Scanning (TLS), Thermal Camra, Ferroscaners, Core Cutter, Microtremore, UPV, Hammer, PSI, PS Logger and other imagers, are being used for building safety assessment.
Dr Mahbuba Begum, Associate Professor of Civil Engineering Department of BUET, presented another paper on “Building Construction: Future Trend, Medium to High Rise Building of Bangladesh.”
Mahbuba Begum emphasised on composite construction by introducing the steel concrete framing system which can be incorporated in medium to high rise building in Bangladesh to ensure safety, ductility and economy.
Steel-concrete composite systems are a viable alternative to both bare steel and reinforced concrete structure, she further said.
Composite members exhibit enhanced stiffness, strength, stability, ductility and economy, she added.
Emdadul Islam, chief engineer of Rajdhani Unnayan Kartripakkha (RAJUK), said during construction of a building both the architecture and engineer remain absent. But their (architecture and engineer) supervision is very important during the construction of any building.
He also urged everyone to follow proper building code during its construction.
AMM Toufiqul Anwar, Professor of Civil Engineering Department of BUET, said: “Many buildings collapsed during their construction and we have to find out the reasons.”
“We must take lessons from our every engineering failure,” he further said,
Dr Sheikh Sikandar Ali, Professor of Civil Engineering Department of BUET, also spoke.
Many engineers, architectures, teachers and students of civil engineering departments of BUET and other private universities were present at the seminar.
Saiful Islam Hilali, chief marketing officer of Bashundhara Cement, and Engineer Saroj Kumar Barua, Manager, Technical Support Cement Sector of Bashundhara Group, were also present.
Saiful Islam Hilali, chief marketing officer of Bashundhara Cement, said Bashundhara Group has been working for welfare of the nation and its people since 1987.
Bashundhara Cement, sole brand of Bashundhara Industrial Complex Ltd (BICL) is produced in two most modern factories of the country at Mongla and Madanganj (Narayanganj), he also said.
Bashundhara Cement first started its production in Mongla in November, 2012, and is eyeing to start production at Madanganj factory within a few months. The Mongla factory has a capacity to produce 1.62 million MT per year and the production capacity of Madanganj factory will be, when in full swing, 2.10 million MT per year which will make the production of Bashundhara Cement 3.72 million MT a year.
