Causes and remedies of Building Collapse in Nigeria.
| Major Causes of building collapse | Major recommendation | Author(s) |
|---|---|---|
| Structural defects, poor material, construction defects | Pre-investigation of building materials before incorporation into the building works. | Olusola & Akintayo, (2009) |
| Poor concrete practices and technology | Improvement of the existing concrete technology. Tests on the quality of cements has to be conducted regularly by the concerned regulatory agencies. | Ede, et al. (2016) |
| Structural problem due to the presence of smectite in the soils. | Soil characterization must be conducted before building is done. Government should assist people in cases where smectic contents are high. | Una, et al. (2015) |
| Geotechnical and geological reasons. | Soil characterization must be conducted before building is constructed, especially for high rise buildings. | Oyediran & Famakinwa (2015) |
| Low quality reinforced steel bars | Continuous random test of building materials is done to determine when specifications are deviated. Tests are to be conducted on the materials to ensure that they are of the required standards. | Adeleke, & Odusote (2013). |
| Low quality reinforced steel bars | Ensure that quality steel bars are used and sanctions are prescribed for observed corrupt practices as it regards to local production of reinforced steel bars. | Kolawole, & Akanni, (2012) |
| Lack of pre & post construction investigations, under design, improper supervision, use of substandard material, poor quality funding & construction. | Geotechnical reports must be available before, during and after construction of buildings. | Amadi, et al (2012) |
| Management, structural defects, construction defects, poor materials, Geophysical, corruption, legal. | Awareness and trainings on the dangers and causes of building collapse should be regularly conducted for stakeholders in the built environment and landlords, property developers and contractors. Safety measures are to be ensured during the building process | Ayedun, et al (2011). |
| Substandard concrete and concrete materials. | Emphasis on strict adherence to specifications. Closer collaboration among the professionals in the built environment is very key to ensure quality control and assurance. | Oduola (2010) |
| Flaws in the structure, poor quality materials, construction defects, improper design and dilapidation, foundation issues in buildings on reclaimed lands. | Compressive investigations of the geophysical characterization of building sites are highly recommended. | Oni (2010) |
| Lack of adequate building survey. | Government and professional buildings should regulate the practice of building survey. | Dahiru, & Okotie, (2010) |
| Incompetent construction workers, low quality of construction materials. | Recruitment and effective supervision of skilled and competent workers. Quality checks on, and sanitization of the building materials before incorporation into the building works. | Oke & Abiola-Falemu, (2009). |
