Construction Project Quality and Safety Management System Based on Blockchain Technology

Blockchain technology has unique advantages in quality management and traceability. It has had successful cases in food, medicine, e-commerce and other fields, but it is still less applied in the construction industry. According to the requirements of cscec-2020-z-12 funded by the science and technology R & D plan of CSCEC, this paper introduces blockchain technology into the construction industry and constructs a blockchain based construction project quality management system to help improve the quality of construction projects. Design the blockchain technical architecture, select the alliance chain to build the system, complete the setting of data layer, network layer, consensus layer, incentive layer and contract layer, and ensure the normal operation of the system. Then, four functional modules of the system are designed in the application layer, which are user management module, contract management module, quality management module and quality traceability module, and the business processes of quality management and quality traceability using the system are displayed. The experimental results show that the construction project quality and safety management system based on blockchain technology proposed in this paper has a shorter management time, a management range of more than 90%, and a strong management ability.
