    Assessment of the Correlation between the Quality of Building Materials and Strength of Concrete Members in the Building
    (International Journal of Applied Engineering Research, 2018-03) Ogunde, Ayodeji, O.; Egbanubi, kehinde, C.; Ameh, John , O.; OPeyemi, Joshua
    The constituents of concrete have a significant amount of influence on the strength of concrete. Consequently, this research work addressed the use of compressive strength test to determine concrete strength. To achieve the aim, experiments were carried out on three different aggregate sizes-19mm, 16mm, and 13.2mm. The results showed the silt percent contained in each tested aggregate, 3% for fine aggregate, 1% for 13.2mm aggregate, and 0.05% for both 16mm and 19mm aggregate size. It also showed the moisture percent contained in the fine aggregate sample was 2.56%, the workability of the tested concrete of mix ratio1: 1 1 2 2 was 0.95, the Impact Value (toughness) of the aggregates; 9.01% for the 13.2mm size, 7.13% for the 16mm, and 7.95% for the 19mm size of aggregate. The compressive strength test showed that the 19mm size aggregate had the highest strength after each seven days. For the test on concrete members (column), Schmidt hammer test was carried out to determine the strength and variation in the workmanship of each tested column. The result of this research work showed that the 19mm aggregate had the most strength; and that the aggregate sizes influence the strength of the concrete. The research also showed that for each concrete member there is high variation in strength due to variation in workmanship. It is recommended that columns should be tested periodically for variation in strength to avoid building collapse.

    Ethical ideology and Nigerian building professionals’ ambivalence toward ethical issues
    (London South Bank University, 2018-11) Ameh, John , O.
    Consensus is that corruption and other ethical lapses are prevalent in the construction industry. Professional ethical lapses often lead to huge economic loss in the form of additional cost of projects, rework engendered by poor quality of works, frequent maintenance management of buildings, and in extreme cases collapse of building. Ethical ideology accounts for variation in individuals’ perception about moral issues and consequent behaviour notwithstanding existence of professional code of conduct. The purpose of this study is to examine the dimensions of ethical lapses within the Nigerian building industry, and also investigate factors that influence professionals’ ultimate decision to engage or refrain from ethically questionable behaviour in the procurement of building project. The study methodology involves cross-sectional survey of key built environment professionals in consulting, contracting and client organisations. The findings will form needed benchmark for resolving ethical issues in the building industry in developed and developing countries.

    Human Resource Management in the Nigerian Construction Firms: Practices and Challenges
    (Journal of Construction Business and Management, 2017-07-13) Ameh, John , O.; Daniel, Emmanuel, I
    Improvement on human resource management is critical to overall productivity and cost effectiveness in the construction industry. This study assesses the current human resource management practices in the Nigerian construction organisation and the challenges confronting it. Questionnaire survey was adopted for data collection while the sampling technique was purposive. Ninety eight human resource managers and construction professionals in two categories of construction organisations (client organisations involved in housing development and contractor organisations) were sampled. The results reveal that due process was followed in the recruitment process but the selections of desired candidates were often hampered by interferences and competitive work conditions. Furthermore, training and development practices were superficial, involving orienting newly recruited employee on facilities for optimum performance rather than developing employee job related competences. Provision of appropriate/modern working tools and equipment and provision of incentives and benefits to staff were the prevailing motivation and labour union practices. Challenges facing human resource management practice in the Nigerian construction industry include high labour turnover, interference at the selection stage, competitive wages and compensation issues among others. Further research is required to assess the impact of identified human resource practices on productivity and project performance.

    Stakeholders Response to the Menace of Building Collapse in Lagos, Nigeria
    (London South Bank University, 2018-11) Ameh, John , O.
    The phenomenon of building collapse in Nigeria and the accompanying fatality and magnitude of economic loss have been issues of concern to stakeholders, particularly the professionals in the built environment and the government. This paper outlines historical records of building collapse incidences in Lagos State, Nigeria in the last 10 years and examines stakeholders’ response to the menace with a view to providing intervention policies for resolving ethical issues in the building industry in developing countries. Content analysis was used for data obtained primarily from secondary sources. Findings reveal that the menace of building collapse is pronounced in the Ikeja and Lagos administrative divisions, and common among the two- and three-storey residential building categories. Timely interventions of Building Collapse Prevention Guild and Building Control Agency led to significant reduction in the incidences and fatalities. It is hoped that other developing countries facing similar ethical issues in their building industry will lean from the interventions in Lagos State, Nigeria.
