THE VALUE CREATION MECHANISM OF DESIGN-LED EPC PROJECT CONSORTIUM

The design-led EPC model has become a widely adopted engineering construction approach internationally. However, it still faces challenges such as the lack of clear understanding among consortium members regarding its value creation mechanisms, which significantly hinders its broader application. To address this issue, this study conducts an in-depth exploration of the value creation mechanisms among consortium members under the design-led EPC model. Focusing on the value creation processes of each consortium member in design-led EPC projects, this research systematically identifies the relevant elements and constructs value creation networks for both the design leader and the contractor. Through a literature review, the core elements of value creation within the consortium are identified, including enterprise needs, value creation behaviors, and the multidimensional value dimensions of EPC projects. On this basis, from the dual perspectives of fulfilling enterprise needs and enhancing project value, the study systematically investigates the specific value creation pathways of each consortium member. It further analyzes the hierarchical structure of value creation for both the design leader and the contractor, respectively building value creation network models for each. This reveals the internal logic and driving mechanisms behind the value creation processes of all consortium members.
