A Semi-Explicit Practical Coding Method for Prefabricated Building Component Parts in China

In the context of building industrialization, the dissemination and transmission of information related to prefabricated building component parts are of paramount importance throughout the building’s life cycle and the entire industry chain, necessitating high standards of information integration. At present, the development of information coding for prefabricated building component parts in China is hindered by various challenges, such as the lack of uniform norms and standards across different regions, as well as significant differences in the composition and character length of coded information categories. Through reviewing academic papers and society, group, and local standards related to the coding of prefabricated building component parts, this article identifies the importance of component part coding information categories. Considering the readability of codes, a practical coding system is adopted for the coding design, proposing a semi-implicit practical coding method for prefabricated building component parts. This method has strong flexibility and wide applicability. Additionally, a common coding system for component parts is devised to address the issue of missing information caused by the limited characters of component parts codes. This system enables comprehensive life cycle information management of component parts of prefabricated buildings and promotes the application of prefabricated buildings in China.
