Abstract: Managing construction resources of large-scale projects such as labor and equipment has always been the core of engineering management, and its dynamic and precise requirements can be met through modern information and communication technologies that provide a strong technical guarantee. Facing the management challenges of high resource mobility, multiple cross-operations, and complex professional technique, we have developed a comprehensive technology system of construction positioning–including personnel positioning and device positioning–that is applicable to different operations demanding different positioning accuracies and response speeds, in combination with the construction of hydropower projects in the lower Jinsha River. Applying this system and related data technologies, we can collect the real-time data of personnel and device positioning, analyze comprehensively construction behaviors and real-time feedback, and manage dynamically resource investment, moving track, operating status, etc. Thus, a real-time refined management of construction resources is achieved for large-scale hydropower projects, improving the safety and quality management of engineering construction.

Key words: hydropower projects, positioning data, dynamic management, behavior analysis
