Item Optimization of Fire Stations Services in Minna Metropolis using Maximum Covering Location Model (MCLM)(Journal of Applied Sciences & Environmental Sustainability, 2017-07-04) E.A. Adesina, J.O. Odumosu, O.O. Morenikeji, E. Umoru, A.O. Ayokanmbi, E.B. OgunbodeThe study is aimed at determining the optimal locations for the present geographical location of fire stations service in Minna Metropolis considering the distance and benefits of the users to the facility or if there is needs for an additional fire stations service to be added using Maximum Covering Location Model (MCLM). The existing fire stations service in the study area were three (3) which served as facilities (Supply) while 2012 and 2014 number of fire incidences and the population were used as the centroid points for the wards and also utilized as demand points which are twenty-five (25) in the study area. The impedance time was set to be 5-minutes and 2000 meter radius was used as a distance factor. After the assessment of the coverage of the existing fire stations service using (MCLM), It was discovered that two wards were uncovered (based on the imposed time constraint) while nineteen (19) wards were uncovered based on the distance factor. Thus, the three fire stations service could not guarantee total coverage in the study area. Therefore, recommendations was made for the location of five (5) new fires stands to serve the uncovered wards in the study areas in case of emergency.Item Analysis of spatial distribution of worship centres using maximum location model in part of Minna, Niger state, Nigeria(Journal of Advanced Research Design, 2017) E. A. Adesina, J. O. Odumosu, O. O. Morenikeji, O. G. Ajayi, E. S. Onuche, K. H. BabalolaThe research uses the Maxisum Location Model to determining optimal location of existing worship centres in part of Minna Metropolis with the primary goal of locate p facilities such that the total demand-weighted distance between demand nodes and the facilities to which they are assigned is maximized (i.e. This model was adopted to solve the problem of noise generated from the sound-speaker) used by these worship centres during their services to the nearest neighborhood using 500meters as a distance factor. Since there are no restricted rules governing siting of worship centres it may not be located everywhere optimally, therefore, more areas were affected when a distance less than 500meters criteria was used while some areas are farther from the noise based on their location at optimal distance of 500meters and above. Spatial analysis was carried out on the sufficiency or otherwise of churches and mosques within the study area. Multi-criteria queries were carried out and results revealed that some worship centers need to be relocated because the area they were are too congested and also generate more noise to the environment through sound-speaker used. Recommendations were made to predict future deficiencies if relevant government agencies fail to provide more rules and regulations in siting of worship centers as the population increasesItem Construction Programmes and Programming: A Critical Review(Emerald Reach Proceedings Series, 2019-05) Olubajo, Oluseun Olukemi; Hughes, Will; Schweber, LibbyPurpose–The purpose of the study is to explore the dominant ideas in research on the management of time in construction. The focus of research has been to improve techniques for optimising the timing and sequence of activities. Design/Methodology/Approach– A critical review of research on construction time management, challenging the typical focus. We examine the assumptions different authors make, underline the limitations of the dominant research approaches and examine the prospects for developing a new approach to researching these issues. Findings– The dominant approach in literature focuses on unique activity traits in construction planning and measurable patterns between time-related variables. This assumes that time in construction can be managed by changing the way activities are calculated. These approaches have not been correlated with improvement in performance. Social practice theory may help to explain how programmes figure as one of many objects used during construction. Research Limitations/Implications– The focus is on reviewing indicative literature from key journals in construction management. The implication is that research is needed about how such documents are used in practice, which goes further than optimising plans in theory. Practical Implications– Future research could focus on understanding the context of construction planning practice and shift the debate from a focus on optimisation to practice. Originality/Value– An interpretivist approach with a focus on how tools such as planning documents are used on site. Social practice theory may provide a clearer explanation of the place of construction planning within the practice of construction management. This could provide solutions that deal effectively with stakeholder expectations around timely completion of construction projects.Item Factors Affecting Project Planning Efforts in Akwa-Ibom State(School of Environmental Technology International Conference 2016, Federal University of Technology Minna, Niger State, Nigeria., 2016-05-12) Olubajo, Oluseun Olukemi; Idoro, Godwin; Jimoh, Richard AjayiAll construction projects are unique and the amount of effort invested into planning activities will depend on the nature or the character of that project; as no two construction projects are identical. This prompted an investigation to evaluate the factors affecting the efforts invested into project planning activities at the pre-contract stage in Akwa Ibom state. The aim of the study is to evaluate the factors affecting efforts invested in project planning amongst selected consultants. A field survey involving 92 project consultants was adopted to achieve this objective. Data was collected using structured questionnaires and analysed using mean and relative importance index. It was discovered that the demands of the client, the clients budget and the construction method to be adopted ranked highest amongst others as having more impact on the measure of efforts invested in planning and indirectly on the performance of the construction Projects. The study suggests that all stakeholders collaborate more frequently by building stronger partnerships and aligning all actors as an integrated supply chain.Item Strategic Management Initiatives in Small and Medium Scale Construction Companies in the Federal Capital Territory, Abuja(School of Environmental Technology, Federal University of Technology Minna. PMB 65, Minna, Niger State Nigeria, 2018-04-12) Olubajo, Oluseun Olukemi; Olawuyi, Babatunde JamesSmall and medium scale construction companies’ account for the bulk of Nigeria’s construction industry and the impact of this sector on the growth of the national economy is seminal. The practice of strategic management in small and medium scale companies is low, however this does not imply that these firms lack intent or initiatives to grow and compete. It is on this grounds that this study seeks to examine the initiatives of small and medium construction companies and their performance in the Federal Capital Territory Abuja. The objectives are to examine the competitive strategies adopted by Small and Medium Construction Companies, to evaluate the dynamics involved in initiating and implementing strategic intentions and to determine its relationships with their performance. The study adopted a survey design approach using questionnaire to gathering data from supply chain participants involved in 50 construction projects sites. The study data was analysed using descriptive statistics, mean item score and correlation test. Findings revealed that differentiation strategy is the most highly adopted competitive strategy by small and medium construction companies and the formation of strategic alliances improves the delivery of business objectives as a supply chain strategy. A competent the work force is essential for the success of any organisation and a significant correlation exist between the strategic management initiatives of small and medium and organizational performance. The study recommends the harmonisation of company efforts in small and medium scale organizations in line with strategic objectives for improved performance and growth of developing economies.Item Evaluation Of Factors Influencing Planning Efforts in Building Projects In Uyo, Nigeria(Journal of Contemporary Research in the Built Environment, 2017-09-01) Olubajo, Oluseun Olukemi; Kuma, ShienPurpose: This study investigates the factors influencing planning efforts in building projects in Uyo, Nigeria. The focus is specific on those factors that significantly affect the pre-contract planning stages of building projects. Design/Methodology/Approach: A survey approach was adopted in the collection of data among key professional consultants involved in building project planning and execution. A sample selection of Architects (32), engineers (43) and Quantity Surveyors (38) was drawn from 56 project sites and 9 consulting firms in the study area adding up to a sample size of 113 professional consultants. Structured questionnaire were administered with 81.4% response rate. Finding: The outcome from analysis of the square sum of ranks indicates factors such as client’s demand, client’s policy and planning procedures as the most significant factors influencing pre-contract building project planning efforts. Research limitations/Implication: The investigation of the factors was limited to those most applicable to the pre-contract planning stage of building projects. Originality/value: The conclusion is that clients have significant influence on the amount of efforts invested in planning and performance of building construction projects
