    Assessment of void periods in residential buildinds in Minna, Nigeria
    (UNIVERSITY OF THE WITWATERSRAND, JOHANNESBURG, 2024) Rukaiyat Adeola Ogunbajo; Shien Stephen Kuma
    The period of void is a major challenge faced by investors in residential buildings in Minna. Re-letting vacant apartments takes a while, and in many cases, newly completed residential buildings experience voids. Therefore at what level of void periods, residential building types are most vulnerable, as well as locational differences are the critical questions that informed this study. Thus, the study aimed to provide an in-depth assessment of void periods in buildings among residential neighbourhoods in Minna, Nigeria. The objectives are to assess the level of void periods, analyse variations across residential building types, and explore neighbourhoodlevel differences in the study area. The study utilized a quantitative research design, employing a structured questionnaire that was distributed to ESVs, LEAs, and property owners who oversee the management of the 1,500 residential units that were selected for the sample in 13 different sted analysis of variance, and the Games-Howell post hoc test were used for data analysis. The findings revealed aggregate mean void periods of 4.87, 5.47, 5.13, and 7.03 months for tenement, 1-bedroom, 2-bedroom, and 3-bedroom residential building types. This outcome varies significantly among the building types across the 13 neighbourhoods in terms of those with high and low void periods. The study concludes that there are relatively high void periods in the Minna residential property market and the need for collaborative efforts towards stemming the tide.

    Influencing Factors of Land Dispute in South West Nigeria
    (FEDERAL UNIVERSITY OF TECHNOLOGY, MINNA, 2024) Dairo O. Elizabeth; Sule A.I.; Nuhu M. B.; Ogunbajo R.A.
    In Nigeria, particularly in the South-West, the unpleasant consequences emanating from land ownership disputes such as killings, destruction of properties, ethnic and tribal violence, political protests, and multiple sales of land result in a seeming or assumed ambiguity about the real ownership of the land. It was on this basis that this work comparatively analyses measures adopted in managing land disputes in Southwest Nigeria, with a view to developing guidelines for the most effective and efficient measures. A systematic random sampling method was used in selecting the landowners and lawyers, and a purposive sampling technique was used in selecting the directors in the states. Primary data were collected using a questionnaire administered to 955 landowners, 456 lawyers, and 17 directors. Also, seven experts were interviewed, which was made up of 4 lawyers and 3 directors. Descriptive, chi-square, Anova, content analyses, and case studies were used for the analysis. The findings as regards the overall type of disputes in communities in the south west indicate that 22.5% of the respondents encountered boundary disputes, 21.8% encountered land grabbing disputes, 21.5% encountered community land disputes, 30.6% encountered ownership property rights, and the remaining 13.6% encountered encroachment disputes. The land owners found that greed and lack of love generate land disputes in Ondo State, coownership and idle land in Ekiti State, and poverty and lack of love in Osun State. The lawyer found that encroachment and virgin land cause land conflicts in Ondo, Ekiti, and Osun states. The director found that co-ownership, encroachment, and virgin land cause land disputes in Ondo State, Ekiti State, and Osun State respectively. The study recommended that the government, through its agencies, should look into the establishment and creation of more land resolution agencies to resolve issues around land matters. The government should mitigate the nefarious activities of land officers or community land owners by encouraging them to do the needful.

    Assessment of Public Real Estate Investment Performance in North Central Nigeria: A Literature Review
    (FEDERAL UNIVERSITY OF TECHNOLOGY, MINNA, 2024) Zakari U. Dodo; Mohammed B. Nuhu; RukaIyat A. Ogunbajo; Adeyosoye B. Ayoola
    This paper examines the performance of public real estate investments in North Central Nigeria, focusing on their impact on economic development, infrastructure, and social welfare. A comprehensive literature review was conducted, drawing from recent studies on public real estate investment in developing nations. The methodology is a systematic literature review to assess the performance of public real estate investments in North Central Nigeria. Academic journals, government reports, and conference proceedings from the past decade were reviewed to gather relevant information on the subject. A search was conducted using keywords such as "public real estate investment," "North Central Nigeria," "housing development," "infrastructure," and "economic impact." The findings highlight how public real estate investments contribute to job creation, housing development, and infrastructural improvements. However, significant challenges such as inequitable housing distribution, limited access to amenities, and inefficient planning remain. The paper provides insights into how these investments can be better aligned with community needs for improved social and economic outcomes.

    Potential Impact of Smart Building Elements on Commercial Property Investments in Lagos State, Nigeria
    (FEDERAL UNIVERSITY OF TECHNOLOGY, MINNA, 2024) Joy E. Omoare; Unekwu J. Adama; Namnso B. Udoekanem; Rukaiyat A. Ogunbajo
    The impact of smart building elements on commercial property investment in recent years including the landscape of real estate investment has undergone significant transformation across the globe, particularly in emerging economies such as Nigeria. This study explores the potential effect of Smart Building Elements (SBEs) on commercial property investment in Nigeria, as the global narrative of real estate investment has been progressively influenced by the Fourth Industrial Revolution Technologies (Industry 4.0), particularly through the integration of (SBEs). In developed regions like the United States, evidence in literature suggests that investors are securing higher premiums in rents and transaction prices by incorporating technologies such as the smart building elements which include sensors, smart meters, smart security cameras, smart thermostats and smart lighting systems into commercial properties. SBEs address the complex demands of commercial spaces which include enhanced comfort, improved accessibility, heightened security, and efficient energy management. The study methodology is based on a review of published articles in peer-reviewed journals and conferences, accessed from online search engines including Google scholar, ResearchGate and Scispace. Results show SBEs facilitate predictive maintenance, enhance space utilization, achieve significant returns on investment, increase tenant satisfaction and retention. Notably, stakeholders (investors, facility managers and tenants) in the real estate sector are aware and accept SBEs. Nevertheless, predominant literature did not capture the tangible economic impact and the operational benefits SBEs can deliver in Lagos state, Nigeria. This research gap underscores a critical need for in-depth empirical study on how SBEs specifically affect commercial property investment outcomes in Lagos state, Nigeria.

    CHALLENGES OF RENTAL HOUSING AFFORDABILITY BY TEACHERS IN MINNA, NIGER STATE, NIGERIA.
    (International Anatolian Scientific Research Congress, Kayseri – Turkey, 2022) Falilat Abdulmalik; Rukaiyat Ogunbajo; Sekinat Abdulkareem
    Affordable housing has become a serious and considerable challenge especially for low incomes households which resulted from continue growth and expansion of the urban centre. There has been a serious threat to rental accommodation in the urban areas especially to certain grade of workers whose income in most cases are based on their salaries. The challenge becomes not only to provide the houses but to make the houses affordable to the average Nigerian worker. The study examined the challenges of rental housing affordability by teachers in Minna, Niger state, Nigeria. Data were collected from 927 teachers between grade levels 07-17 in 20 purposively selected public secondary schools within Minna metropolis. Information were obtained on the annual income, property rental value and challenges of rental housing affordability by teachers in the study area. Appropriate descriptive and inferential statistics were employed in analyzing data collected. The study revealed that there was a positive significant correlation between annual income and property rental value of the teachers, which implies that as long as there is increase in annual income of teachers, property rental value of teachers in the study area will increase. Lastly, high cost of building materials among others is the strongest predictor of rental value and thus a key contributor to explaining the level of rental housing affordability of teachers in the study area. Among other recommendations to reduce the rental values of properties occupied by teachers in the study area, government should implement existing staff housing programme. While implementing this programme, various income groups should be put into consideration. Emphasis should also be placed on low and medium housing units specific for teachers. This will reduce the housing cost thus making it more affordable to many teachers.

    Determining house prices in low income neighbourhoods of north-central nigeria: a categorical modelling approach.
    (University of Sao Paolo, 2022) Ogunbajo, R. A.; Olabisi S. A; Wali R.I
    Research shows that the most widely used estimates of the impacts of housing attributes on house prices are derived from hedonic models. The hedonic model assumes that the prices of dwelling units is composed of a number of factors, thus using a regression analysis, the impacts of each of these factors often measured on numeric scales can be estimated. However, researchers from social and behavioural sciences in developing countries have recently begun to look in the direction of the quality of the influencing housing attributes on house prices. These attributes are best measured qualitatively on ordinal and/or nominal scales. As such, an important development in multidimensional data analysis is the optimal assignment of quantitative values to qualitative scales. This form of optimal quantification (scaling, scoring) is a general approach to treat multivariate categorical data (Srijan, 2009). This study utilised the categorical modelling approach to determine the contributory effect of housing attributes on rental house prices in North-Central Nigeria. The categorical regression model uses the optimal scaling methodology as developed in the Gifi system to quantify categorical variables according to a particular scaling level, thus “transforming” categorical variables into numeric variables. Having adopted + 10% precision and 90% confidence level, a total of 1,134 housing units were sampled by stratified and random selection. The data used were generated through questionnaire. Nine housing attributes were found to sustain residential buildings in the study area and these accounted for 45% and 61% variance in the rental prices of two major low income house types. Results suggested that the identified housing attributes significantly predicted rental values for the low income house types. The mean of predicted rental values were further computed for each house type and compared to the means of the actual rental values collated in the course of data collection and presented with line graphs. Results showed predicted values that are reasonably similar to the actual rental values of the dwelling units. Thus suggest a reasonably accurate prediction of rental house prices using the categorical regression approach.

    THE CONTRIBUTORY EFFECT OF EXTERNALITIES TO THE VOID PERIODS FOR RESIDENTIAL BUILDINGS IN MINNA, NIGERIA
    (FEDERAL UNIVERSITY OF TECHNOLOGY, MINNA, 2018) Ogunbajo, R. A; Adewusi, A. O; Usman, B.S.; Ayoola, A. B
    A number of residential buildings have been observed to suffer longer void periods in recent times despite the increasing demand for residential accommodation across urban areas. Landlords and real estate investors are sometimes faced with the challenge of replacing tenants within the shortest possible time, thus being unable to adequately recoup the invested capital on residential properties developed in particular neighbourhoods. This study provides evidence on the contributory effect of externalities on the void period for residential buildings in Minna. The sample for the study constituted a total of 207 three bedroom bungalows which fell into void at any point between January 2014 and December 2016 – covering a three year period. Adequate data were provided for 144 of these dwellings which spread across nine neighbourhoods, representing 70% response rate. Data were sourced from practicing estate surveyors & valuers, and estate agents in the study area, as well as occupants of housing units that fell within the sample. The sourced data provided information on the void periods of sampled dwelling units as well as required information on selected externalities. Collated data were analysed using the optimally scaled categorical regression analysis. The regression model explained 51% of the total variation in the void period of residential buildings. Findings revealed that the void periods of residential buildings reduced with closer distances to shopping centers, recreation centers, major roads, and improved electricity supply. On the contrary, educational institutions, health care centers, refuse dumps, security and sources of water supply were found not to have significant contributions to the void period of three bedroom bungalows in the study area. The study recommended that real estate investors’ should be mindful of externalities in an area before embarking on real estate developments in order to ensure satisfactory returns on their investment.

    Assessement of Ergonomic Factors among Non Acadamic Staff of School of Enviromental Technology, Federal University of Technology Minna
    (School of Environmental Technology Conference, SETIC, 2016, 2016) Y.D. Mohammed, Alumbugu, P.O. & R.A. Jimoh
    Implementing ergonomics in workplace improves health and safety among staff, increase job satisfaction of workers, thereby leading to increase work quality services and productivity. In a related development, ergonomics can also increase overall employees’ morale, decrease workers compensation costs and decrease absenteeism and turnover among the workers. However, implementing ergonomic principles at work place has been low; hence this study assessed ergonomic related factors of workers within the School of Environmental Technology using physical measurement and personal observation of 10 nonacademic staff. The 3 factors identified for assessment were anthropometric measurement (using measuring tape), light intensity measurement (using Lux meter) and quick exposure check (using checklist). The results of the anthropometric measurement assessment showed that only Hip width was found to match with current furniture for most workers, while other parameters were found to be highly mismatched. The results of quick exposure showed, that most workers have experienced moderate exposure levels for back (static and moving), shoulder/arm, wrist/hand and neck. Based on the lighting level at workstation of workers, there was an indication of inadequate lighting level. It can be concluded that based on the 3 ergonomic factors assessed, implementation level was low. Additional improvement to workers workstation is required coupled with long term planning of new chairs that are customized for workers need, ability to rest or lumber support with additional head support and adjustable table. This will enable the user to adjust the height of the table to ensure that his hand is able to wrest nicely on the table
