Factors Influencing the Performance of Construction Projects in Akure, Nigeria (Published)
This study was carried out to identify the factors influencing the performance of construction projects in Akure, Nigeria. A questionnaire survey was conducted and forty six (46) factors were identified, categorized into eight (8) groups, evaluated and ranked according to participants’ perspectives. Fifty (50) questionnaires were distributed as follows: 12 to clients, 18 to consultants and 20 to contractors. The outcome of these analyses showed that all the respondents agreed that construction projects were influenced by all the forty six factors indicated by the questionnaire. However, the analysis indicated that the top ten (10) factors that have the highest average index showed how these factors are affecting construction projects. Based on these findings, this study recommended that contractors’ progress payment should be made on time as well as minimizing change orders during construction to avoid delays. Also, consultants should give full commitment to monitor the project progress and ensure the work was according to specifications and satisfactory quality; meeting owner needs and expectation within the project budget and stipulated time. Finally, continuous coordination and relationship between project participants were required through the project life cycle in order to ensure project performance.

Assessment of the Relationship between Risk Allocation and the Performance of Building Infrastructural Projects in Nigeria (Published)
Risk in building infrastructural projects is the exposure of construction activities (related to building) to economic loss, due to unforeseen events or foreseen events for which uncertainty was not properly accommodated. With building infrastructural projects becoming increasingly complex and dynamic in nature as well as the introduction of new procurement methods, many stakeholders are interested in an approach that will enhance project performance within their organizations. The study assessed the relationship between risk allocation and performance of building infrastructural projects. A total of one hundred and eighty copies of questionnaire (180) were administered on randomly selected stakeholders (comprising construction clients, consultants and contractors and insurance companies), out of which one hundred and fifty (150) was found valid and applicable for this study, and this constituted 86.6% of the sample size. Statistical techniques employed for data analyses were percentage of Relative Importance Index (%RII), Cronbach’s alpha reliability scale Test, T- test and Spearman’s rho correlation analysis. The analyses revealed that clients, consultants, contractors and insurance firms risk allocation affect project performance. Risk elimination by management was ranked first among the tools used to minimize construction projects risk. All the results of the Cronbach’s alpha reliability test were above 0.5 which indicated that the items were reliable for the measurement of risk allocation and risk factors. An average Spearman’s rho correlation coefficient of 0.6912 showed that risk allocation among stakeholders was significant and directly related to project performance at 0.05 level of confidence. The Paired samples T-test on risk allocation and project performance revealed that there was no significant difference between risk allocation and project performance. It was concluded that there was a positive relationship between building infrastructural risk allocation and project performance. The study therefore recommended that building infrastructural stakeholders should triangulate and use multiple models during the feasibility and viability planning stage of building infrastructural projects in order to reduce pit hole at the construction stage.
