About 24 persons died while 133 injured across the 25 states in 2012.

The other incidents within the year was also linked to the use of substandard building materials as 132 died, while 163 sustained injury in 2014. In 2015, one person died when a 3-storey building at 87 Swamp street Odunfa, Lagos Island collapsed on October 21.
The other incidents within the year was attributed to gas explosion and deserted building marked for demolition, just as 19 persons were injured. Only one death case and 19 injuries were recorded in 2015, considered to the lowest number of fatalities so far.
However in 2016, the highest death recorded was during the collapse of a church building (Reigners Bible Church) in Uyo, Akwa Ibom state on December 10.
About 50 persons died , while over 100 others were injured/trapped at the time of the incident, due to inadequate roof support and poor construction/ supervision. This was followed by the collapse of a 5-storey building at Lekki Garden, Lekki Phase 1 Ikate Lagos on March 8, where 35 persons died and several injured over poor quality construction materials, workmanship and supervision, increase in the number of floors from three to five.
The third highest incident recorded in the same year involved a 2-storey building under construction at Kano State University of Science and Technology , Wudil that collapsed on August 22, killing 20 persons and injuring five.
Throughout the year, 137 persons died, while over 50 were injured. The incidents were linked to heavy rainfall, structural defect, poor quality of construction materials, workmanship and supervision. Also, the highest incident recorded in 2017, was the collapse of a four-storey building in Lagos on July 26, 2017, that led to the death of eight persons.
About 32 persons died , while over 62 sustained various degrees of injury within the year under review. The entire incident in 2017 was rated as distressed building marked for demolition, weakened and dilapidated building. Also, in 2018, the highest fatality recorded was when a seven-storey building under construction in Port Harcourt, Rivers State collapsed on November 23, killing 17 persons due to overload.
About 23 persons died, while over 12 were injured all through the year. The collapses were attributed to weak and dilapidated structures likewise distressed buildings marked for demolition.

About 20 persons died , while 43 others were injured.
Within the year, 58 persons died in different locality where similar incident occurred. They were linked to poor concrete casting and the developer’s failure to liaise with approving authorities before embarking on the project.
To this end, experts who spoke to LEADERSHIP advocated compulsory Environmental Impact Assessment (EIA) on all proposed building sites before construction. The chairman of NICE, Abuja chapter, Engr. Dominic Onuh Akuboh, sought the strengthening of student’s industrial training and work experience scheme, adding that government should prioritise technical education at all levels.
He recommended that government should collaborate with professional bodies to review building codes and educational curricula especially in tertiary institutions to include relevant courses such as failure analysis, forensic science, reliability, probabilistic analysis of failure modes, geotechnical/foundation engineering.
While disclosing that developers should comply with all regulations pertaining to building designs, modifications, construction approvals, supervision, standard material specifications and permits, he challenged them to provide details of soil investigation and land survey in their sites.
Akuboh pleaded with regulators and professional bodies to collaborate by ensuring proper supervision of design, work, quality of materials and personnel at all stages of construction projects. Lending his voice, Engr. Kanno Ukoabasi, pointed out that qualified civil engineers should supervise the execution of buildings and ensure strict adherence to contract specifications. He recommended that soil investigation, material test and Environmental Impact Assessment(EIA) must be made compulsory for all residential, institutional, industrial and commercial buildings. Ukoabasi noted that the Standard Organization of Nigeria (SON) should be vigilant to ensure that building materials imported into the country conformed to standards requirements.
To curb the menace of building collapse, he enjoined stakeholders in the building and construction industry to join forces with the regulatory and professional bodies to tackle the problems headlong.
