Abstract: In the aim of improving project management efficiency, controlling project quality, and reducing the impact of human factors on project quality, the construction information, concrete temperature, concrete vibrating, and grouting in the construction process are intelligently monitored and controlled via information technology, digitalization, automatic control and other technologies. In view of this, an intelligent management system for construction quality under the intelligent construction environment for Yangfanggou Hydropower Station is developed based on the quality management modules of the BIM management system as well as the intelligent temperature control, intelligent vibrating, intelligent grouting, and whole-process image acquisition system integrated by the BIM management system. The construction quality information is managed dynamically through real-time collection, real-time analysis, and decision feedback. The problems in construction quality control, information collection, analysis, and decision-making in the EPC and traditional construction mode have been solved. The present intelligent system has improved management efficiency and management quality, and achieved better management results.

Key words: hydropower station construction, intelligent management system for construction quality, EPC, intelligent dam construction, BIM management system, Yangfanggou Hydropower Station
