Digital dynamic control over whole construction process of large hydropower projects

Construction of large-scale hydropower projects is faced with the complexity of production factor flow, the accuracy and effectiveness of physical measurement, and the problems in forward-looking and real-time management caused by the differences in management systems, business processes and technological processes of all parties involved. This paper reports a series of in-depth studies on how to integrate engineering construction and information technology for hydropower development in the lower reaches of Jinsha River, such as positioning technology and other new-generation information technologies. These studies focus on conducting integrated research and development of a hybrid superposition positioning technology with different accuracies in positioning and different speeds of response in complex environment; formulating a standardized process flow with a uniform management form and coding system for each specialty of electrical construction; developing mobile online application systems; conducting research and development of key process intelligence technologies and equipment systems; and building an information system through the whole process of project pricing. Achievements in these studies ensure the acquisition of comprehensive, true, accurate and real-time data through project construction management, and realize digital dynamic control over the whole process of engineering construction ? flow factors of personnel and equipment, core business processes such as quality and safety; key technological processes such as concrete pouring temperature control and cement grouting; and real physical costs such as unit engineering measurement. The management technologies presented in this paper would promote the optimization of whole management chains such as business chain and process chain, and lay a basis for intelligent construction, and it should be a core part of intelligent technology in engineering construction.
