An evaluation of risk factors impacting construction projects in Ghana

Purpose – The purpose of this paper is to identify and assess the likelihood of occurrence and degree of impact of the risk factors on construction projects within the Ghanaian construction industry.Design/methodology/approach – A survey of randomly selected samples yielded responses from 34 contractors, 46 consultants, and 23 clients or owners (private and public) within the Ghanaian construction industry. Literature review is used to identify 25 relevant risk variables which were grouped into ten composite factors and then incorporated into the design of the survey instrument. Survey response data were subjected to descriptive statistics and analysis of variance (ANOVA), and subsequently the exposure rating levels were determined, which enabled the categorisation of the probability‐impact scores in low, medium and high levels.Findings – Results of this study indicate a disparity of the ranking of the degree of occurrence and impact among the groups. There was a statistical difference at the p<0.05 level...
