Abstract:
With popularization and application of the project general contracting model in the water conservancy and hydropower industry, the integrated design and construction model led by design has become an effective means of reducing costs and increasing efficiency, unified management, and scientific decision-making. This paper reviews the recent advances inthe research of general contracting models, design models, construction models, and design and construction collaboration models for the water conservancy and hydropower industry inChina and overseas; and clarifies the current pain points of this industry and its major bottlenecks in developingand implementing such integrated models. We investigatethe key roles and concept of applying the informatization technologyforefront, deepening technological innovation and practice, and adopting the top-down design and lean construction modelsin solving the existing problems of low design optimization efficiency in design and construction integration, cumbersome mutual feedback of design and construction information, and low level of intelligent construction. To further develop this concept, taking the digital twin technology as a basic application framework for the future, we expound key research directions for further research, and suggest how topromote the integrated design and construction in hydropower developmentand overcome the shortcomings in water conservancy informatization.
