Principal component analysis of challenges facing the implementation of value engineering in public projects in developing countries

摘要

Over the past decade, value engineering (VE) has developed to become a recognized methodology with ordinarily comprehended tools and procedures. Its adoption in public projects in developed countries is credited with meeting stakeholders' expectations. Although this may be so for construction industries in developed countries, the situation is bleak for developing countries. This paper considers the challenges facing the successful implementation of VE in public projects among developing countries. Using an empirical questionnaire survey, respondents were invited to rate their perception of 22 challenges identified from literature. This paper is based on a survey of construction and consulting firms based in Ghana. The data set was subjected to factor analysis. Correlations between the 22 variables show that five key components underlie the challenges facing VE in developing countries. Findings and recommendations of this study may be useful to construction professionals who are seeking innovative ways to enhance value for money.
