5. Conclusion and recommendations
The construction industry plays a pivotal role towards the social and economic development of countries worldwide. At the social level, it aims to construct projects and infrastructure facilities that fulfil the community needs, meet or exceed clients’ and end-users’ requirements on time, within budget and as specified. At the economic level, it increases countries’ GDP, offers job opportunities and supports other industries to excel. However, it has a negative impact on the environment in terms of resources and energy consumption, pollution and waste generation. This called for the construction industry to be more sustainable. ADP is one of the important stages of the construction process, as many of the decisions adopted during this stage affect the sustainability and performance of the project throughout its life cycle. RM is widely applied in different phases of the construction projects; however, its application in ADP received scant attention in construction literature. The research identified 18 key risks that affect the sustainable delivery of construction projects during ADP. The architect, the client and the project manager were the highest ranked responsible parties for the occurrence of these key risks. Based on the results of the field study conducted by the authors, the research developed a framework to facilitate the integration of RM into ADP as an approach for delivering sustainable construction projects.
