A framework of an integrated sustainability and value engineering concepts for construction projects

Abstract

Sustainability and value enhancement are major considerations in the modern construction world. Thus, the integration of sustainability and Value Engineering (VE) will have the potential to boost the value of a construction project. This research was therefore aimed to develop a framework that integrates VE and sustainability concepts in the construction industry in Sri Lanka to improve project values. Both quantitative and qualitative research approaches were used in the research. The questionnaire survey that was carried out as a part of the research had a response rate of 68.9% and collected data were analysed using Relative Importance Index (RII). The survey was followed by 15 individual interviews conducted with experts and the findings were analysed using content analysis. The study revealed that both VE and sustainability are used in isolation in the Sri Lankan construction industry. Hence, the relationship between the two was determined and a framework was developed for integrating SC and VE.
