Abstract

The use of substandard materials for the construction of residential buildings within Lagos metropolis is experiencing a growing concern for both the government and the residents. The construction of half-lived and substandard buildings contributes to negative consequences ranging from rapid deterioration of building elements, premature failures of key building components, and sometimes building collapse. This study attempts to investigate the factors influencing the use of substandard construction materials for the construction of residential buildings in Lagos State. This research collected primary data through a cross-sectional survey of professionals engaged in the construction of buildings and building owners within the study area. Two sets of structured questionnaires were developed and administered to each of the groups of respondents, respectively. The collected data were analysed using descriptive and inferential statistical tools. The results show that factors influencing the use of substandard construction materials for the construction of residential buildings include corruption, use of quacks, contractor’s greed and selfish interests, and client’s financial constraints. The results suggested no significant difference in the perception of contractors and building owners on the factors influencing the use of substandard materials for the construction of residential buildings. The study concludes that the use of substandard building materials for the construction of buildings could cause structural failure, high maintenance costs, incessant building defects, and accelerate deterioration of building elements and components. Building clients suggest to engage professionals and refrain from patronizing quacks.

Abstract

A house is an essential facility that affords an abode, provides habitation and shelter adequacies. Affordable housing presumes access to a conducive, functional, and sustainable dwelling by the majority of the people within a locality. The study investigated the factors mitigating the actualization of affordable housing for low-income masses in the selected area. Survey research was adopted for the study. The population for the study is made up of two groups comprising low-income masses and construction professionals. The study adopted a multi-sampling method. Both convenient and random sampling techniques were utilized to gather information from the respondents. Statistical Package for Social Sciences (SPSS) was used for descriptive (frequency, percent, and mean score) and appropriate inferential analysis. Results indicated factors weighing down the provision of affordable housing as well as factors precluding accessible housing for low-income masses. Also, the response from construction professionals showed the level of agreement on factors impeding the provision of affordable housing. The trail to alleviate the effect of the non-affordability of housing for low-income masses becomes perceptible and addressed.

Abstract

The ongoing digital transformation of the construction industry, known as Construction 4.0, requires students in built-environment programs to gain adequate exposure to emerging technologies. Despite this need, many faces significant barriers to meaningful engagement. This study explores the factors limiting students’ learning experiences related to Construction 4.0 in Nigerian universities and polytechnics. Using a stratified random sampling method, 154 students from one university and one polytechnic were surveyed through a structured questionnaire. Data were analyzed using frequency distribution, relative importance index, and the Mann-Whitney test. Results identify key obstacles such as limited peer collaboration, insufficient funding and resources, and weak infrastructure. There were no statistically significant differences in these barriers between university and polytechnic respondents. The study concludes that addressing the current limitations requires institutional reforms, including infrastructure investment, curriculum development, faculty training, and support for student collaboration, particularly in polytechnic settings.
