Bangladesh is known as an earthquake prone country due to its geological location. Expert says a moderate tremor will cause thousands of buildings collapse only in Sylhet city and we all know what happened when Rana Plaza collapsed on 24 April 2013. Given its vulnerability, Oxfam with other organizations are targeting the semi-skilled workforce, in terms of earthquake preparedness who are liable for all the buildings construction. The major work behind the construction of residential building in Bangladesh are mostly done by the informal sector like masons, bar-binders, plumbers who are employed by the owners or builders. This workforce neither has academic lessons nor any formal training. While there have been initiatives by the governments towards improving seismic performance of new constructions by incorporation of seismic design in the building construction process, it can be still anticipated that local masons and small contractors will continue to play significant role in the building construction process. So any enhancement in their skills in seismic resistant construction can significantly help in improving the earthquake resistance of informal and non-engineered building and hence considerable reduction in the loss of human lives and properties can be addressed due to earthquake. Specialists are expecting a severe earthquake in this area in near future, which will cause serious infrastructure and other losses. By the initiative of human casualty, damages of Bangladesh Government, a seismic zoning map of Bangladesh was prepared in 1993. Where the country was divided into three zones. The most severe zone is the zone no. 3, which includes the north and northeastern parts of the country. Sylhet is the northeastern region of Bangladesh and probability of earthquake in Sylhet is higher than other areas of this zone. But most of the population and policy makers do not perceive seismic risk to be important.

The data table and pie charts below will help to
understand the result.

only 25% construction project supervised by engineer.

26. Awareness program should be encouraged.
Owner should provide good quality material
that the contractor must follow.
Supervision engineer must be provided.
Arrange a campaign for unskilled worker for
good construction work.
