    Analysing the Knowledge Management Culture of Construction Firms in Abuja
    (Environmental Technology and Science Journal, 2023-12) Olubajo, Oluseun Olukemi
    Construction projects are temporal in nature and involves project managers assembling construction professionals that are often disbanded immediately a project is completed. This disbandment causes construction knowledge that firms accumulate from the experience of teams to be lost or go uncaptured. This is a concern for firms that need to retain knowledge to remain competitive and often compete for limited contracts. Research into construction knowledge tends to focus on the relationship between the culture of organisations and construction knowledge. A second piece of the literature focusses on the nexus between construction knowledge and organisational performance. However, investigations that examine the knowledge management culture in construction firms with a view to analyse various issues and factors involved is limited. Therefore, the aim of this study is to examine the knowledge management culture within organizations in the Federal Capital Territory, Abuja, Nigeria. A descriptive survey approach is adopted, and data is obtained through questionnaires in Abuja. The results showed that many construction firms struggle or fail to formally capture/share construction knowledge because many employees have little or basic knowledge of knowledge management techniques or tools and often rely heavily on face-to-face interactions to share knowledge. The study argues that a superior knowledge of as well as an increased adoption of knowledge management techniques and tools by employees can significantly enhance the ability of an organisation to share and capture construction knowledge to minimise knowledge loss.

    Examining the Resilience of Construction Supply Chains to Disruptions Triggered by Covid-19 in Abuja,Nigeria
    (Environmental Technology and Science Journal, 2024-06) Olubajo, Oluseun Olukemi; Olusola, Ezekiel Ayodeji
    Disruptions are a concern to construction practitioners because it hinders work flow and construction activities. Research into disruptions in construction work tends to focus on the causes of disruptions in the flow of materials or labour. Another theme in the literature focuses on the relationship between disruptions and the performance of sectors in construction. However, investigations that examine the resilience of construction supply chains to incidents of disruptions are limited. This study aims at examining the resilience of construction supply chains to disruption triggered by Covid-19 in Abuja. The study adopted a survey approach, and data was obtained from structured questionnaires administered online to 90 stakeholders and 70 participants involved in different aspects of construction responded. The study found that contractual disputes and scarcity of materials ranked highest as the effects of disruption and that construction practitioners adapted to the disruptions majorly by reducing the number of material requisitions or by integrating equipment to cater for the shortage of workers. The study argues that members of construction supply chains responded to disruption triggered by Covid-19 with changes and adapted the way they worked or operated as acts of resilience

    Quality and Perception of Public Housing Provision in Nigeria andImplications for Low-Income Earners
    (Journal of Salutogenic Architecture, 2024-12-14) Akande, Oluwafemi Kehinde; Olubajo, Oluseun Olukemi; Ibraheem, Yusuf
    This study critically evaluates the quality of public housing provisions for low-income earners in Abuja,Nigeria, aiming to enhance housing policies and delivery outcomes. Employing a descriptive survey approach, data were collected from 150 residents using structured questionnaires focusing on housing quality and occupant preferences. The findings reveal a significant mismatch between the housing options provided and the disposable incomes of low-income residents, leading to widespread unaffordability. Despite increases in housing supply, the needs of low-income earners remain unmet, adversely affecting their living conditions, health, and well-being. The study highlights that current housing policies inadequately address the economic realities of low-income households. It recommends a thorough review of housing provision policies to better align with residents' financial capacities. Furthermore, the research advocates for a collaborative approach among housing designers, developers, and government agencies to promote the development of high-quality, affordable housing. By addressing these issues, the study seeks to contribute to policy amendments that ensure sustainable housing solutions for low-income populations,ultimately improving their quality of life and social inclusion.

    Analysing the Physical Condition of Buildings: A Case Study of an Institution of Learning in Nigeria
    (School of Environmental International Conference (SETIC 2024), School of Environmental Technology, Federal University of Technology Minna. PMB 65, Minna, Niger State Nigeria, 2024-11-29) Abass, Abdulshakur; Ogunbode, Ezekiel Babatunde; Olubajo, Oluseun Olukemi
    Buildings depreciate with time and gradually perform less than they are expected. This is a concern for building owners and users. Research on depreciation of buildings tends to focus on identifying or categorising defects. However, investigations that examine the condition of public buildings that inhabit large and frequent users is limited. The aim of this research is to analyse the physical condition of public buildings in an institution of learning. This study adopts a case study approach involving physical observations and the condition rating of three buildings in an institution of learning in Nigeria. The results of the analysis showed that there were several similar defects on the walls, floors, roof, electrical and mechanical services. The results on the condition of the buildings showed average condition index values indicating that the buildings were in moderate condition with the laboratory in a better condition with an average condition rating of 0.58 and the offices with an average condition rating of 0.52 and the classes with an average condition rating of 0.44. The study argues that improving the condition or state of the buildings would lead to enhanced building performance.

    Managing Ambiguity in Construction Projects in Nigeria: The case for Selecting and Achieving Set Milestones
    (Proceedings of the 8th International Project and Construction Management Conference (IPCMC2024)-Resilience in the Built Environment, Yildiz Technical University, Faculty of Civil Engineering, Department of Civil Engineering, İstanbul, Turkey., 2024-06) Olubajo, Oluseun Olukemi; Akande, Oluwafemi Kehinde; Daniel, Emmanuel Itodo
    Investigations that explore the knowledge, selection, and influence of milestone management practices on the performance of construction projects are limited. This study examined the dynamics involved in managing ambiguity and achieving set milestones in construction projects in Minna, Nigeria. Using the quantitative method, questionnaires (n = 150) were distributed to obtain data from construction professionals who adopted milestone management practices on their projects, of which 119 responded. This resulted in a remarkable 79% response rate, and high data reliability (0.962) was obtained. Notably, the findings underscore the pivotal role of specific milestone selection criteria in building construction projects as identified and ranked by the respondents. Scope of work (0.861) ranked first; schedule estimation (0.845) and quality assurance (0.845) ranked second; budget significance (0.844) and resource allocation (0.844) ranked third. Further findings show a significant relationship (i.e., p-value = 0.00) between the dynamics of milestone management and the performance of projects. The study accentuates the urgent need for appropriate selection and management of milestones for timely project completion in Nigeria. With this widely known practice, construction professionals would be able to represent and manage work activities and achieve set time expectations regardless of project disruptions.

    Exploring the Circle of Consumption Around Reused Construction Demolition Waste: Evidence from Construction Sites
    (Proceedings of the 5th International Conference of School of Environmental (SETIC 2024), October, 2024, School of Environmental Technology, Federal University of Technology Minna. PMB 65, Minna, Niger State Nigeria., 2024-10-14) Akale, Sokolayam Favour; Daniel, Emmanuel Itodo; Olubajo, Oluseun Olukemi
    Reuse of construction materials/components from dismantled structures is an economic sector that is scarcely regulated and highly fragmented. Research into the reuse of components or materials extracted tends to focus on maximising the benefits when deconstructing building or civil structures. However, investigations that explore the dynamics involved in dismantling a built structure, trade and reuse of materials or components extracted with multiple actors is limited. This study aims at exploring the circle of consumption around reused materials or components extracted from dismantled structures. The study adopted a mixed method approach, and data was obtained from observation, interviews and structured questionnaires from stakeholders involved in deconstruction works. The results revealed that there are patterns in the consumption of extracted components from demolished structures that should be regulated involving construction supply chains. The study argues that construction practitioners actively shape the way components extracted from demolished structures are repurposed and reused in subsequent construction works. The study contributes to the literature on circular economy and deconstruction by focusing on the dynamic relationship between members of construction supply chains and the reuse construction materials or components.

    Condition Surveys and Assessment of Buildings: A Review of Approaches Adopted
    (Proceedings of the 5th International Conference of School of Environmental (SETIC 2024), October, 2024, School of Environmental Technology, Federal University of Technology Minna. PMB 65, Minna, Niger State Nigeria., 2024-11-07) Abass Abdulshakur; Olubajo Oluseun Olukemi
    Building condition surveys and assessment is increasingly becoming an important issue. This is because people spend a lot of time residing or working in buildings and knowledge of the condition of a building can reduce the likelihood of fatalities in the event of a disaster or building collapse. Research on building condition surveys and assessment tends to adopt varying approaches that seems to be contradicting. This study aims at examining the dominant research approaches on building condition surveys/assessment and to underline their assumptions, limitations and arguments. A review of the literature on condition surveys and assessment of building is executed. This literature is categorised into major themes, synthesised and the typical focus is challenged. The results show that four dominant approaches have been adopted in literature namely: model-based approach, fuzzy theory approach, condition index approach and the digital approach. The study argues that a combined or hybrid approach provides an alternative approach that will unearth reliable data on a building that can be triangulated or validated by comparing the different data on the condition of a building.

    Equipment Acquisition and Maintenance Capability of Construction Firms in Abuja, Nigeria
    (ATBU Journal of Environmental Technology, 2024-06-01) Olubajo Oluseun Olukemi
    Research into construction equipment tends to focus on output and criteria for selection. However, investigations that examine the capability of construction firms to acquire and maintain equipment are limited. This study examines the capability of construction firms to acquire and maintain equipment in Abuja, Nigeria. A survey approach was adopted, and data was obtained through self-administered questionnaires to 45 construction practitioners from 45 construction firms purposively sampled in the Federal Capital Territory Abuja, Nigeria. The study used descriptive statistics to analyze the capabilities of firms, and the results showed that the method of acquisition ranked as the highest factor, with a mean score of 4.70, which affects the equipment management capability of firms. The results also showed that 65% of firms cannot outright purchase construction equipment, 56% rely largely on renting, and 62% often adopt an outsourced maintenance approach rather than in-house maintenance. This explains why many construction projects do not always benefit fully from the potential or output of construction equipment. The study argues that construction projects can benefit maximally from the potential of construction equipment when construction firms leverage their capabilities and project resources prudently. The study contributes to knowledge by shifting the debate in the literature on equipment and focusing on capabilities. The study has implications for construction firms that seek to develop capabilities that can promote their business interest and competitive advantage.
