    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.

    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.
