Edinburgh Napier University,UK Ashraf Elhendawi Construction mega-projects are typically associated with cost overruns and time delays due to conflicts of interest between diverse stakeholders. This research investigates the influence of the partnering approach and the adoption of Design and Build (D-B) contractual agreement on the behaviour of stakeholders on mega-projects. Through a case study, the significant factors that influence stakeholder management are appraised, such as cooperation, developing trust, and a dearth of communication. The research concluded that mutual trust, transparency, leadership, the well-defined scope of work, a clear definition of responsibilities, collaboration, and training are the main success factors of partnering projects. The research also emphasised that Building Information Modelling (BIM) plays a vital role to secure the mentioned key successful factors for partnering. Furthermore, BIM facilitates achieving project objectives with the adoption of D-B contracts. This research contributes to the developing body of knowledge addressing the application of partnering in construction. The outcomes of this research will be beneficial for clients, contractors, project managers, and contract managers when taking into account future execution plans for D-B projects. Forthcoming studies can develop a framework to combine various stakeholders to obtain optimum satisfaction. 2020 2020 01 17 10.54216/IJBES.030101 https://www.americaspg.com/articleinfo/22/show/875
