Identifying barriers in constructing green buildings in Oman: A study on project contractors' experience

Purpose: Oman commitment for Sustainable Development Goals 2030 pushes green building at the forefront of construction industry. However, its green building progress is slower than other Gulf Cooperation Council countries, and only a handful of local contractors have been involved in green project development. Understanding the barriers to green project delivery will open avenues for better project planning and preparation. This research aims to identify the barriers experienced by the contractors when constructing green buildings in Oman. Design/methodology/approach: Qualitative research, via a semi-structured interview process, explores the barriers experienced by 14 contractors when constructing Leadership in Energy and Environmental Design (LEED) green building projects in Oman. Using NVivo 12 software, thematic analysis was conducted through the generation of coding and themes which enable the identification of the relevant barriers. Findings: The research uncovered 10 barriers and grouped them into five categories. The five categories are as follows: (1) insufficient skills development, (2) lack of government support and regulatory adjustment, (3) limitation in materials procurement, (4) documentation and coordination limitation and (5) difficulty in green rating compliance. Originality/value: The research identified 10 barriers of constructing green buildings in Oman. These barriers gravitated on 4 issues: knowledge and competency, green rating requirements, government involvement and materials procurement. It streamlined clusters of the potential research area for more effective green building action plans in the future. Two barriers are deemed uniquely applied to Oman, namely "lack of needed regulatory adjustment" and "absence of local rating tools". This insight can serve as a valuable steppingstone to push more green buildings for the country.
