The collapse of building has been an issue of great concern to all and sundry in Nigeria and yet these buildings are major contributors to the development of any nation. Therefore, when a building collapses, it fails to render the functions which it should perform to the people and the government. A building is regarded as collapsed if the whole st...

... results obtained in Table 4 corroborated the view of literature that the implications from the menace of building collapse wreaks havoc on the people and the environment. Results obtained in Table 5 shows the response from the respondents on the (remedies) ways to prevent the collapse of building in Owerri, Imo State Nigeria. We have, adherence to designed reinforcement details which have theRIIof 0.99 ranking 1 st , avoid the use of non-professional (quack) and testing of soil to 0.97 ranking 4 th while the constant supervision has the RIIof 0.82 Ranking 5 th in the table. ...Context 2
... implies that when buildings collapse it either kills the occupants and or destroys their properties, and the occurrence further renders them homeless, emotionally wrecked and inancially destabilized. In Table 5 , 'adherence to designed reinforcement details' had RII of 0.99 and ranked 1 st position whereas 'constant supervision ranked 5 th position amongst the remedies associated to building collapse. This implies that it is only an incorrupt professional that can adhere to the designed details and carry out soil testing and make use of high-quality material to achieve a high degree of construction work that will last the text of time. ...Citations
... Evaluation of naturally occurring construction materials is important for sustainable development. The rate of building collapse in Nigeria is on the rise (Anosike, 2021;Bamigboye et al., 2019;Owoyemi and Bamigboye, 2013). Additionally, buildings are experiencing the phenomenon of rising damp. ...
The quality of the aggregates used in plastering mortar contributes to the properties of the mortar. This study
evaluated the suitability of two grades of sand – sharp sand collected along active/old river courses and plastering
sand collected from borrow pits – as plastering materials. X-ray diffraction and X-ray fluorescence analysis were used
to study their mineralogy and major, minor and trace element components. Grain-size distribution analysis, natural
moisture content, specific gravity, Atterberg limits, matric suction and permeability tests were also carried out on the
sand samples. In both sands, the silica content was more than 80%. The plastering sand had a higher natural
moisture content than the sharp sand. The fineness modulus ranged from 1.31 to 1.83 and 0.53 to 1.01, respectively,
for the sharp sand and the plastering sand. The permeability coefficients and matric suction of the sharp sand were
larger than those of the plastering sand. This implies that sharp sand will allow easier water passage through its
pore spaces, therefore tending to exist in a dryer state than plastering sand. The tested sharp sand may be suitable
for plastering because the test results were within the acceptable limits for good plastering materials according to
national and international standards.

... Building collapse happens to be a phenomenon which spreads round the globe. This implies that it is an occurrence not restricted to just underdeveloped and developing nations but is also found in developed nations (Anosike, 2021). Many individuals have been made homeless due to recurring building collapses, and many have been devastated by the death of loved ones. ...
High-rise residential and commercial development in developing countries like Nigeria has been spurred by both the rapid growth of the population and the pressing need to protect the country's limited land supply in areas of commercial development. However, recent years have seen an increase in the number of building collapses in Nigeria, which is a cause for concern. This study uses statistical method on historical data to highlight the scenarios of the collapse of high-rise buildings in Nigeria and drawing a relationship with it to sustainable construction. According to this study, Nigerian high rises have a low rate of collapse despite the country's high rate of collapse, but the number of fatalities in the collapse of these structures is alarming. The high death toll associated with these collapses is a negative indicator for achieving the Sustainable Development Goals of the United Nations (SDGs).
... Standard organization of Nigeria (SON) conducts quarterly factory inspection visit to all manufacturers of these materials quarterly to ensure that the materials produced meet the requirements of the relevant standards. All reinforcement steel rods for reinforced concrete produced in the country have identification mark for purpose of monitoring and traceability [2]. From council for the regulation of engineering in Nigeria, it has been established that construction of any single storey in waterlogged area as well as building of two-storey and above including fall structures and factory buildings, shall be carried out by a registered engineer or registered engineering company [3]. ...
Population growth in cities couple with lack of spaces for building forced people and government to embrace the concept of high-rise building. The construction of high-rise building involves proper idealization, estimation of loads, analysis of idealize structure, adequate specification of sizes and material. The paper investigated the mechanical compliance of market supply by reinforced concrete iron rod in with BS 4449 requirement of diameter, yield strength, elongation, and stress ratio through hydraulic universal testing machine. As a result, among the eight manufacturers only F and H complied to the size specified on the reinforcement. On yield strength only F and on % elongation only C, E and H complied with standards.
