Abstract
This paper is an attempt to explore the barriers to integrating sustainability into construction project management in developing countries. To this end, a comprehensive review of the literature is conducted, as a result of which a list of 30 barriers is culled from existing studies. The list of barriers is subsequently assessed in terms of relative importance index (RII) through a survey questionnaire administered to Iranian construction industry experts, resulting in a dataset of 176 completed questionnaires. Findings bring to light the most influential barriers to incorporating sustainability in construction projects for a developing country. These were: (1) lack of understanding of the potential selfbenefits of proactivity and high economic risks that unsustainable practices may carry, (2) inadequate assessment of risks and a silo-based approach, namely, insufficient cooperation among practitioners, research institutions and environmental organisations and (3) the lack of a systematic approach to planning and acting for the fulfilment of sustainability goals. As one of the first studies in its kind, the paper offers invaluable insight for researchers, practitioners, and policy makers, in supporting the transition of construction project management practices towards fulfilling sustainable development goals.
Highlights
There is an enormous demand for delivering construction projects in developing countries, as a result of their agenda for providing much needed infrastructure for advancing their economies
relative importance index (RII) values are showing the importance of each factor (Holt, 2014)
Higher RII value proves that respondents have assigned a higher score to the specific variable
Summary
There is an enormous demand for delivering construction projects in developing countries, as a result of their agenda for providing much needed infrastructure for advancing their economies. A review of the literature, shows that very few studies have targeted construction project management This presents a major problem, given that as announced By (International Energy Agency, 2018) in 2018, the construction industry is responsible for about 41% of total energy consumption globally, and close to 40% of total CO2 emissions. Despite these facts, integration of sustainability into construction project management practices has been very slow, with outcomes being far from satisfactory (Marcelino-Sádaba, González-Jaen, & Pérez-Ezcurdia, 2015).
