The study investigates the effects of building collapse risks on the stakeholders in the Nigerian built environment. Survey research design was adopted in carrying out the research and five cities in Nigeria were selected (Abuja, Ibadan, Port Harcourt, Owerri and Lagos). The target population for the study is the stakeholders in the Nigerian built environment: key professionals in the construction industry, clients/developers and users of the finished product. A sample size of 1999 was chosen using Taro Yamane method. The data generated from 1860 respondents representing 93 % of the distributed questionnaires were presented using frequency tables, pie -charts and bar charts, while analysis was done using percentages and weighted mean. The findings of the study show that building collapse risks have multifarious factors which were categorized as Economic/Financial risks, Socio-political risks, Human related risks, Physical risks, Environmental risks and Law/legal risks. The negative effects of these risks are: loss of property, loss of reputation and integrity of the contractors, loss of lives, legal tussle among the stakeholders, etc.. It was also found out that economic/financial risks have the predominant effect on the stakeholders, followed by Human related risks, Socio-Political risks, Physical risks, Environmental risks and lastly Law/Legal risks. It was recommended that all hands should be on deck to curb the havoc caused by building collapse as the effect is usually felt by all and sundry. There should be adequate funding and monitoring of the activities of all Emergency Management Agencies.
This paper investigated the critical success factors of project implementation in Nigeria. The study is motivated by the very low success rate of project delivery in the country which has created obvious problems of economic waste and end user unsatisfaction. The study sampled the opinion of fifty selected project professionals presently working in six project sites located in Anambra, Imo and River States. An objective realization instrument developed using twelve (12) factors identified in the literature as possible drivers of success in project implementation based on the Likert five-point scale of ranking. Weighted scores of respondents to the factors were analyzed using factor analysis, while the effects of the quantified weight of the critical factors were analyzed using the regression tool. Results of the analysis among others show that Environmental factors are more critical to the success of project implementation than skills portfolio of the project team. Collective responsibility among project stakeholders is a necessary condition for successful project implementation; Ability of project professionals to generate accurate designs, cost and time estimates will minimize the negative effects of economic instability on successful project delivery. Commitment of Clients to project financing obligations is a necessary condition for contractor commitment to project plans. The recommendation is that there is need for adequate environmental scanning, monitoring and evaluation at the planning stage of projects.
This study presents a fuzzy decision-making trial and evaluation laboratory (DEMATEL) analysis of the internet challenges of the internet of things (IoT) implementation of construction projects in Nigeria. The identification of the IoT challenges was carried out through a thorough literature search and discussions with 27 built environmental experts. In addition, DEMATEL, an expert judgement-based tool, was used to pick, design, and evaluate a structural model consisting of a causal relationship between defined IoT challenges. Subsequently, the fuzzy DEMATEL was deployed with a view to constructing a structural relationship between the various challenging factors by visualising the dynamic associations between them. Based on the findings of the literature survey and expert evaluation, 18 obstacles to the implementation of IoT in construction projects were classified into cause and effect classes based on their relative parameters of impact. The results suggest that 8 challenges were categorised into the cause group, while 10 were listed into the impact group. The results of this study will enable construction companies, construction industry experts, project managers in Nigeria to enhance their search to design and execute an effective and productive IoT application for their construction projects.
The ERP system has been identified as a tool for delivering information technology (IT) services through software and other critical infrastructures using internet technologies. Given its nature as an industry-driven concept and system, this is universally accepted in industry as a tool to solve practical problems with a view to achieving an integrated enterprise information system. However, a developing country like Nigeria still faces a lot of hurdles in managing its construction supply chain. The aim of this study is to investigate the factors affecting the successful implementation of enterprise resource planning (ERP) systems in the Nigerian construction industry. After a literature search, expert input via the Delphi technique, the study identified four main factors and 21 sub-factors. The Decision-Making Trial and Evaluation Laboratory (DEMATEL) method was used to prioritise the factors and to identify the relationship that exists between the factors. The findings revealed that the key factors affecting the implementation of ERP systems are "A lot of security concerns" (T7), "The management of ERP projects is too complex" (P5) and "The inability to align the ERP solution with the business plans of the organisation" (P2). This study recommends that the findings of this work will help both local and international practitioners alike.
