    Contributions of Construction Project Team to Cost Overruns: The Contractors’ Perspective
    (American Society of Civil Engineers (ASCE), 2014-05) Akinsiku, O. E.; Akintola, A; Ameh, O.; Ige, A.
    A project is adjudged successful if it is completed to time, within the budgeted cost and meets client’s expectation. However, there is the global issue of construction cost and time overruns, which has contributed to poor project performance. Contractors have always been seen as the culprit in this regard, whereas, the contractor is not solely involved in construction projects, there are other project team members who determine the path of the project success. This study assesses the causes of cost overruns, viewing this from the contractor’s assessment of the contribution of its project team members. The study was conducted using questionnaire surveys in which 100 questionnaires were distributed to contractors using purposive sampling; data were analyzed by the use of descriptive statistics. The results show that lack of adequate pre-contract planning and project team coordination are the most significant factor among construction professionals leading to cost overruns. The study made recommendations which are of good benefit to the client, project team members and contractors.

    A study of quantity surveyors’ role in the implementation of public private partnership
    (INTERNATIONAL COUNCIL FOR RESEARCH AND INNOVATION IN BUILDING AND CONSTRUCTION, 2014-01) Sanni, O.A; Hashim, M.; Akinsiku, O.E.
    The procurement of public projects using Public Private Partnership is aimed at achieving value for public money. It is a way of increasing the provision of public works and services without increasing government borrowing. However, quantity surveyors are professionals who specialize in construction cost management and assist clients in achieving value for their money. This paper reviewed the roles of quantity surveyors in the implementation of public projects under public private partnership in Nigeria with the aim of identifying the benefits of their active involvement in the procurement process. This is a report of preliminary study based on literature and interview of selected participants in the implementation of public private partnership projects in Nigeria. The findings showed that few quantity surveyors are involved in the planning and implementation of public projects under public private partnership arrangement. Since quantity surveyors are experts in the contract management, it is recommended that more quantity surveyors should be encouraged to participate actively in the procurement of public projects under public private partnership contracts.

    Causes and effects of rework in building projects in Lagos state, Nigeria
    (INTERNATIONAL COUNCIL FOR RESEARCH AND INNOVATION IN BUILDING AND CONSTRUCTION, 2014-01) Ajayi, O. E.; Akinsiku, O. E.; Oyeyipo, O.
    Rework occurs as a result of design, construction changes and also as variation which is addition, omission and modification of design. Rework cost is on the increase as a result of these changes and it has indirectly affected contract sum, period of completion and quality of the project. Hence this study intends to examine the causes and effects of rework in building projects. Descriptive research design was used for this study and the population consists of construction professionals from consulting and contracting organization. Simple random sampling technique method was used. A structured questionnaire was used as the principal instrument for collecting data from construction professionals in the industry. A total of 98 questionnaires were distributed and 52 were returned given an average response rate of 52%. Statistical package for social sciences (SPSS) 17th version was used for analysis via descriptive and inferential statistic. The findings of the study indicates that changes, defect and quality deviation are the most significant sources of rework on construction projects. Poor communication with design exerts the greatest influence on the rework occurrence on construction sites. The paper also showed that there is significant relationship between rework cost and initial contract sum, initial and final contract period, with exception of final contract sum. In conclusion poor communication with design consultant, use of poor quality materials and poor workmanship are the main causes of reworks in building projects, hence this will affect the client and the project performance in terms of time, cost and quality standard. The paper recommends that early identification of the causes and sources of reworks by consultants and contractors on building projects will reduce the effect of reworks cost on the contract sum, completion time and changes during the design and the construction changes either from the part of the client or the consultant.

    Factors influencing development of small construction companies in Abia and Akwa Ibom states, Nigeria
    (INTERNATIONAL COUNCIL FOR RESEARCH AND INNOVATION IN BUILDING AND CONSTRUCTION, 2014-01) Asuquo, C.F.; Ogbu, C.P; Akinsiku, O.E.
    The economic significance of small construction companies (SCCs) has been globally recognized, especially in developing economies. This study was carried out in Abia and Akwa Ibom States. Its objective was to identify and evaluate factors affecting the growth and development of SCCs in the research area. SCCs in Nigeria often experience stunted growth and show high mortality. Sixty Five (65) SCCs were randomly selected and administered with questionnaires. Data obtained were analyzed using descriptive statistics, and binary logistic regression. The study reveals that majority of CEOs of SCCs are first degree (n=31, 47.69%) and higher national diploma (n=24, 36.62%) holders. Key findings are that there are significant relationships between SCC growth and development and the entrepreneurial/managerial competence of the SCC leadership (p =0.007), financial problems (p= 0.028), work availability problems (p =0.027) and equipment problems (0.034). By implication, addressing these problems will lead to a virile SCC subsector in the Nigerian construction industry. On the bases of the key findings of this study, adequate entrepreneurship training of construction professionals is recommended to the government and other stakeholders in the affected states. It is also advocated that professional and educational institutions should work together to improve the construction management competence of SCCs.

    Effects of project management on abandonment of building projects in Lagos State, Nigeria
    (University of Lagos Press, 2014-10) Dosumu, O.S.; Akinsiku, O. E.
    The study was conducted to investigate the roles of project management on building projects in Lagos, Nigeria. The objectives of the study are to determine the project management factors responsible for project abandonment, effects of poor project management on construction projects and the ways of reducing project abandonments in Lagos state. The study made use of 66 questionnaires out of the 80 that were administered on project managers within Lagos metropolis. The project managers of selected public and private abandoned projects were used for the study and the results of the study were analyzed with SPSS software using percentages and mean scores. The results of the study show that 15 project management factors lead to project abandonments to a high extent while another 15 lead to project abandonments to an average extent. The effects of poor project management on construction project abandonments and stakeholders include conflicts, loss of economic value and reduced standard of living. Project abandonment could be reduced by adequate planning, use of competent professionals and standard project management procedure. The conclusion of the study is that poor project management is key to construction project abandonments and to prevent project abandonment, the study recommends that project managers must engage in adequate planning, cost control and resource management.
