Assessment of the qualitative adequacy of newly constructed public housing in Ogun State, Nigeria

Purpose – The purpose of this paper is to present research assessing the level of qualitative adequacy of newly constructed public housing in urban centres in Ogun State, Nigeria.Design/methodology/ approach – The study followed a quantitative research strategy. A survey of 517 housing units constructed through four different strategies and selected based on quota of their existence in nine public housing estates was conducted with a questionnaire as the key data collection instrument. A five‐point Likert scale was used in measuring the level of qualitative adequacy of four key housing sub‐components. The data were analysed using descriptive statistics.Findings – Residents found the overall housing to be inadequate; they indicated that housing unit attributes were the most adequate and thus contributed most, while neighbourhood facilities were the least inadequate and contributed the least to qualitative housing adequacy.Research limitations/implications – The sample population comprised mainly house head...

Public-Private Partnership (PPP) in Housing Provision in Lagos Megacity Region, Nigeria

Abstract The adoption of Public-Private Partnership (PPP) in housing provision in Nigeria is intended to increase urban housing stock and address housing affordability and accessibility challenges. However, to date, very little is known about how PPP housing schemes have addressed these challenges. This paper therefore explores the extent to which PPP in housing provision has so far contributed to solving the housing challenges in the Lagos Megacity Region of Nigeria. The paper presents the result of a cross-sectional survey of operators of PPP schemes and housing consumers in the study area. The results show that the PPP approach is basically a formal joint venture partnership involving government providing land at subsidised cost and the provision of serviced plots or construction of housing units by private sector partners. Although the approach has provided affordable serviced plots and housing units for a few high income elites, it has contributed very little to the volume of housing units available to low-income people in Lagos. The paper suggests the adoption of a uniform policy on PPP in housing provision and the establishment of a co-ordinating agency. In addition, government involvement in the provision of infrastructure in PPP housing schemes could increase the affordable housing stock accessible to low-income people in the city.

They evaluated housing adequacy based on four key dimensions: ambient condition of interiors spaces, security, utilities and neighbourhood facilities...

e-Procurement adoption in the Nigerian building industry: Architects’ perspective

e-Procurement adoption by architects in the Nigerian building industry was investigated using data derived via a questionnaire survey of 75 architects in consulting and contracting firms, government and clients’ organizations. The data were analyzed using descriptive statistics, Pearson product-moment correlation and content analyses, and the results reveal that most of the organizations employing architects were not using e-Procurement. However, the very few adopters identified used e-mails and websites in communicating, exchanging project information, and sourcing for building services, materials and equipment. The key barriers to the uptake of e-Procurement among architects in the survey were unreliable power supply, low level of awareness among people; and the lack of forum to exchange ideas on e- Procurement use. The paper emphasized the need to address these challenges to ensure a critical mass uptake of e-Procurement by architects in Nigeria.

E-tendering in the South African construction industry

E-tendering is gaining recognition in the construction industry in many countries across the world. However, there is a limited understanding of the extent of its adoption in construction in African countries. Therefore, this research investigated the state of e-tendering in the South African construction industry using data derived from an online questionnaire survey involving 593 respondents, and oral interviews with selected construction clients, professional consultants, contractors and supply chain managers conducted in 2014 in South Africa. The data were analysed using descriptive statistics and content analyses. It was found that 26% of the respondents were involved in e-tendering, and that 72.4% of them used e-mail, while 21% used web- based systems to support the execution of e-tendering activities. It was also revealed that the main benefits were reduction in transaction cost, and turnaround time of the tendering process, while the barriers to e-tendering in construction were slow Internet connectivity; resistance to change; expensive Internet services; and the inability of small-, medium- and micro-sized enterprises (SMMEs) to afford the technology, training and skills needed to engage in e-tendering. The paper concludes by suggesting ways for ensuring a critical mass uptake of e-tendering and maximising its benefits in the South African construction industry.

Assessment of residential satisfaction in the core area of Ibadan Metropolis, Nigeria

ABSTRACT Traditional core areas of urban centers in the developing countries are known for poor housing quality and deteriorating neighborhood environment. However, there is a paucity of empirical studies on the extent to which residents of such areas are satisfied with their housing situations. This study investigated residential satisfaction amongst residents in the traditional core area of Ibadan, southwest Nigeria. The study relied on a questionnaire survey of 856 residents conducted in 2013 in the study area to achieve this goal. Results of the descriptive statistics, factor, and categorical regression analyses reveal that the residents were generally satisfied with their housing situations. They were most satisfied with relationships with their neighbors but least satisfied with the sizes of open spaces within their neighborhoods. Satisfaction with housing units’ attributes and social characteristics of the neighborhood; layout and cleanliness and the provision of utilities and recreational facilities in the neighborhood emerged as the top three predictors of residential satisfaction amongst the residents. The study concludes that instead of contemplating on total clearance and eviction of residents as measures for improving the livability of traditional core areas of urban centers, governments in developing countries need to engage in innovative strategies that will improve the quality of the physical environment and social networks in these communities.
