Even after many developments in project management tools and techniques, there is still a loophole in the traditional approaches, due to which it is no longer effective for managing projects in a dynamic environment. As a result, there is a rising urge amongst the practitioners to implement flexible approaches in large complex projects for its successful completion. However, there is a lack of practical recommendations on how to add flexibility into practice in the construction industry. Thus, the objective of this research is to contribute to the knowledge of flexible project management in the construction industry by identifying the flexibility enablers that can be incorporated in practice, investigating the barriers in its incorporation and providing practical recommendations to overcome them.In this research, five flexibility enablers- iterative planning, iterative delivery, short feedback loops, late locking and continuous locking, have been analyzed and investigated for its application in the infrastructure and healthcare real-estate projects. A case study methodology was adopted to conduct this research. Further, this research has identified 30 barriers that occur in the identification and implementation of flexibility enablers. These barriers were mainly classified into five clusters- Lack of awareness/methodologies, Change resistance, Organizational behaviour, Management processes and Miscellaneous. The research findings suggest the five enablers are not well-established in the construction industry, and there are not many methods available to incorporate these enablers. As a result, it lacks recognition and incorporation in practice. One of the main findings of the research is: planning-based enablers (iterative planning & iterative delivery) are more preferred in the infrastructure sector, while decision-based enablers (late locking & continuous locking) are more preferred in healthcare real-estate sector. Most of the barriers in implementing the enablers occurred as a result of lack of awareness and methods to implement them as well as resistance to change to a new and flexible way of working from the traditional approaches.In order to stimulate the incorporation of flexibility enablers and make them explicit, it is necessary to overcome the barriers that occur in its implementation. This research has proposed a conceptual framework following a linear step-by-step approach of creating awareness, providing insights, encouraging teams and implement these enablers, and further proposed suggestions to overcome the most commonly identified barriers. As the main idea behind stimulating flexibility by incorporating flexibility enablers was to identify and overcome the barriers that occur in its incorporation, hence adopting the proposed framework helps in achieving flexibility in construction project management.
