Construction Safety

After the disastrous earthquake in Nepal, we are entering into a new era of reconstructions. The main focus should be given to protect people’s lives and provide quality assurance. There is a lot of work being put in the design process while not much attention is being given to the construction safety. There should be no more loss of public lives during the time of reconstruction in future.

Preliminary Findings

  • Old houses made from stone, mud, motor joint completely collapsed
  • RCC houses were very less effected
  • High story buildings collapsed due to being built in less plinth area
  • Low story buildings built in large plinth area weren’t collapsed
  • Some of the buildings were found collapsed near the Balaju and Basmati River
  • Some houses found collapsed due to share failure
  • Some houses found collapsed due to insufficient depth of the foundation
  • Some houses found collapsed due to not being symmetric
  • Some houses found collapsed due to poor concrete quality used at the time of construction
  • Some houses found collapsed because of reinforcement not being put in proper places

When asking the owners of the collapsed house, they stated that that none of the houses have been designed with detail by structural engineers, supervised by civil engineers nor have their soil bearing pressure capacity tested. All the destroyed houses were supervised by only local contractors. No mechanisms were set up to produce specifications and the testing of materials. No structural design was in place, no proper architects were supervising the construction site and poor methodology of construction was being used.
