“…Resulting from these, research efforts have been focused on identifying the various factors that contribute to the burgeoning cases of collapsed buildings in this country through physical observations and or sample collection of debris from building collapse sites and oral interviews of eye witnesses or residents within the vicinities. Among the factors identified by the existing studies include the lack of soil test investigation, poor design, dysfunctional construction, lack of adherence to established building standards, lack of enforcement of building codes/regulations/bye-laws, use of substandard construction materials, engagement of non-professionals and poorly trained workmen, poor supervision, excessive loading of buildings, poor maintenance practices, heavy downpour, greed and corrupt practices and others [ 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 ]. Specifically, Oyewande noted that around 50% of the factors leading to building collapse in Nigeria can be linked to faulty design, 40% to fault on construction sites and 10% to product failure [ 34 ].…”
