Adequate housing is essential to the general wellbeing of households. Thus, it is imperative for households to function properly within their residential spaces. However, housing is largely inadequate in the residential core of traditional towns in Nigeria and this is influenced by socioeconomic factors. A cross-sectional survey of 150 housing units was conducted in the residential core of Akure, Ondo State. It examined the impact of sociodemographic factors on housing adequacy in the study area using structured questionnaire. The data obtained were subjected to single-factor descriptive statistics, mean adequacy scoring and categorical regression analysis. The findings revealed that socio-demographic characteristics significantly impact housing adequacy in the study area. Education, income level, length of residence, numbers of bedrooms, household size and tenure status were significant predictors of housing adequacy in this context while tenure status contributed the most in predicting housing adequacy. The study concluded that socio-demographic characteristics of residents are important determinants of housing adequacy in the residential core area of Akure, Nigeria and should therefore, be of utmost considerations in the management and planning of such housing environments

Maintenance of buildings, especially high-rise types, poses a major challenge to resident property managers who are saddled with the responsibility of sustaining property value, building quality, and users’ satisfaction. This is without prejudice to particular factors that affect the condition of such building development. Hence, this study had the general objective of determining the factors that challenge the maintenance of high-rise residential buildings. Case study research design was adopted using a high-rise, multi-tenanted residential development in Lagos, Nigeria. Total enumeration survey and questionnaire administration was undertaken on respondents in the 155 residential units in the case study. The survey had 85.81% (133) return rate and the data derived from duly completed copies of the questionnaire were analysed using descriptive statistics. Major findings of the study suggest that design and poor workmanship, inadequate construction supervision, low quality of original construction, wear and tear, as well as ageing are the key factors that affect the condition of the high-rise residential development. Moreover, variables such as delay in carrying out repair works, service charge administration, outsourcing of services, disconnect between owners and managers, as well as late response to complaints are indicated as posing the major challenges to maintenance management of the high-rise building. This study adopts a case study approach; however, it does not limit the insights and the positive contributions to knowledge therefrom. The study provides significant information that could guide the maintenance decision-making of built-environment professionals with regards to factors of building condition and challenges of maintenance management of high-rise buildings. Also, this study constitutes a significant contribution to the subject of maintenance and management of high-rise buildings in emerging economies like Nigeria.

Choice Behaviour in Sustainable Property Features Adoption: A Tripartite Perspective

M. O. Komolafe , J. T. Gbadegesin — Thu, 21 Dec 2023 00:00:00 +0000

Stakeholders’ attitudes (demand and supply perspectives) on sustainable property features adoption vary, with implication on the sustainable property features market (SPFM). How do market players behave and make choices in the adoption of sustainable property features? This paper examines stakeholders’ choice behaviour within six filtered themes, underpinned in the consumer research theoretical perspective including market information (awareness level), relevance/importance, social cost and benefits, economic cost and benefit, environmental cost and benefit and market feasibility. The study drew upon a sequential exploratory mixed method comprising semi-structured interviews and a questionnaire survey within the six thresholds unraveled. After a pilot study, ten key actors in the sustainable properties sectors, limited by saturation point were interviewed which resulted in a conceptual framework that guided the survey. The questionnaire survey respondents included 56 building contractors, 91 property developers/investors and 404 users randomly selected within the Lagos’ market. The paper found divergent reactions from both demand (users) and supply (investors & contractors) sides. Investors downplayed the market feasibility, relevance and economic rewards of sustainable features. Sustainable building features are essential to contractors, yet their perceptions of economic worth and market feasibility are challenging. The supply side demonstrates lowered economic worth and market feasibility of sustainable structures. The demand side assessment demonstrates a lack of adequate awareness, relevance, market feasibility and economic benefits. On the supply side, there is a willingness to construct with sustainable features, but on the demand side, there is less enthusiasm. Policy directions and blueprint investment guideline on the SPFM for both local and international prospective investors in the developing market were subsequently recommended.

Spatio-temporal Analysis of the Pattern of Land-Use Change of Ife Natural Forest Reserve in Ile-Ife, Nigeria

This study examined the potential application of GIS to detect the spatial pattern of changes in forest land-cover over 33 years (1986 to 2019) using remote sensing data from Landsat Imagery captured. Supervised classification based on a minimal set of informative transition classes was followed. These are human settlements (built-up), cultivated land (Agriculture), Water (no data), forest and undisturbed forest. The study concluded that the natural forest has depleted to the tune of 2,012.71 hectares of land over the period. This implies that human activities in the forest region pose the threat of chasing the undisturbed forest into extinction with a replacement of planted forest

Critical Success Factors and Key Performance Indicators for Real Estate Service Business in Nigeria

J.O. Ogunbiyi , T. T. Oladokun — Thu, 21 Dec 2023 00:00:00 +0000

The goal of this paper was to create a model of Critical Success Factors (CFSs) and Key Performance Indicators (KPIs), which can be used to keep track of service business activities for enduring real estate practice in emerging economies. As a reference to real estate specialists in emerging economies, the study reviewed and analysed relevant papers with respect to the subject matter in various industries, both locally and in developed economies. Appropriate theories were also explored in the paper, which were drawn from the field of business management that suggest how business performance is measured. Using the narrative method of literature review, the study identified successful applications of the models of CSFs and KPIs that can be applied to the real estate industry. Thus, the CSFs in real estate practice are reported as comprising STEEPLE and POET factors and the KPIs are reported as comprising financial and non-financial performance indicators. Corporate real estate management is comparatively new in the real estate industry of African nations such as Nigeria. The corollary is the collapse of many real estate firms with its untold negative effect on the real estate profession. Understanding CSFs and KPIs in service business is a major pathway to developing sustainable real estate practice. This study is a good primer for real estate administrators in emerging markets who want to use CSFs and KPIs to improve their companies' operational effectiveness. This paper's contribution to knowledge is in the originality of bringing to the fore, the applicability of the concepts of CSFs and KPIs for real estate service business management and performance measurement. Quantitative research on the subject is likely to yield further discussions

Optimising Sawdust and Steel Fibre Ratios for Enhanced Compressive Strength in Sustainable Cement Composites

O.A. Obakin — Thu, 21 Dec 2023 00:00:00 +0000

The construction industry's increasing commitment to environmental responsibility and the preservation of resources has accentuated the essential role of sustainable building materials. This study investigated the optimisation of sawdust and steel fibre ratios to enhance the compressive strength of sustainable cement composites. The experimental results indicate that the compressive strength consistently improved over a period of 28 days, irrespective of the quantities of steel fibres and sawdust added. The control beams achieved a compressive strength of 31.92 MPa. The study revealed that an increase in sawdust content led to a decrease in compressive strength, while higher proportions of steel fibres led to increased strength. The highest strength of 38.14 MPa was observed in the group with 1.0% steel fibre and no sawdust. These findings offer valuable insights into optimising sustainable concrete mixtures, emphasising the intricate balance between sawdust and steel fibres in enhancing compressive strength while promoting eco-friendly construction practices
