Impacts of Using Sub-Standard Building Materials on Building Collapse

Abstract

This research was centred on effects of substandard materials usage on building collapse in Nigeria. The study was guarded by three research questions to achieve the aim of the study. Data collected was analysed with statistical tools of mean, percentage and presented with table. Based on the findings of the study, causes for the use of substandard construction materials during construction projects during were analysed that poverty, ignorance, high cost of building materials, inflation of the cost of building materials, greediness of construction workers and lack of good supervision which were verified from the fact that the scores range from 2.50 – 4.00 as established by the cut off mark. The effects of substandard materials on building collapse include among others as comprised constructed building lack standardization, deterioration, cracks, lack of strength to withstand natural disasters,, it makes a building unsafe to inhabit, continuous repairs and checks and building liable to collapse at any time while all the respondents’ negative response comprised only building unable to withstand vibration which were verified from the fact that the scores range from 2.50 – 4.00 as established by the cut off mark while the negative responses were also established from the fact that the mean scores were less than 2.50.The study was concluded by giving some recommendations among which was workshops and seminars should be organized through media and physical means for all the construction teams and the general public on the effect of building collapse.
