Abstract:
Recently, use of integrated procurement systems became popular among private and public sector projects. As a result, ‘Design and Build’ (D&B) method has been increasingly adopted in Sri Lanka’s construction industry during the past decade, even though, stakeholders lack a proper awareness about their role in the project life cycle. Thus, the aim of this research was to identify the role of stakeholders in successful implementation of D&B building projects in Sri Lanka. The methodology of this research incorporated a mixed approach with semi-structured interviews and a questionnaire survey to attain the aim of developing a frame-work for the roles of stakeholders for successful implementation of design and build building projects in Sri Lanka. A purposive sample of nine professionals were interviewed to validate the findings of the literature survey, and manual content analysis was used to analyze the interview findings. In the second part of the study, data collection was done using a questionnaire which was distributed to different parties in the construction industry which included clients, D&B contractors and consultants. Questionnaire findings were analyzed using weighted mean rating statistical methods. According to the findings, client, contractor and consultant were validated as the key stakeholders. The results identified that there are eight stages in D&B project lifecycle and that there are specific roles for stakeholders at each stage. Also there are, enablers and barriers at each stage. Twelve solutions were identified to mitigate the barriers. This research recommends to use for the D&B to Clients, Contractors, Consultants and other stakeholders related to D&B projects. Further, practitioners in D&B construction industry can also use this study to identify the different stages of D&B projects and the roles of stakeholders.
