"As a matter of fact, over 91 buildings have collapsed resulting in the death of over 354 persons in Lagos from 2012 to date," COREN President Sadiq Abubakar said.
Mr Abubakar said the leading causes of building collapse vary from one location to the other.
He said some buildings collapse as a result of ageing as well as the use of substandard construction materials.
He said that other factors included illegal change of use of buildings, illegal addition of floors, quackery, and inadequate or lack of supervision and oversight.
He added that other factors included faulty foundations, a lack of soil/geotechnical investigation, and sharp and corrupt practices.
