Standardization plays a fundamental, strategic, and leading role in the sustainable and sound development of prefabricated buildings. Aiming at the problem of the lack of information technology-supported full-life standard and high-efficiency management mechanism after the official release of the construction industry standard, this paper has made relevant explorations and practices, and proposed and implemented a design of the construction industry standard management system based on the alliance chain. First, we use the high reliability of the alliance chain and the decentralization of smart contracts to solve the problem of reaching consensus based on trust and efficiency during the standard update process. Then, combined with the IPFS distributed file storage technology, the problem that the blockchain cannot save files was overcome. Finally, the developed sharing community subsystem and standard users are used to establish a process feedback mechanism and collect usage opinions to facilitate the iterative improvement of the standard and achieve the full life-cycle management of the standard.
