Industrialized construction has raised the requirements of procurement methods used in the construction industry. The rapid development of e-commerce offers efficient and effective solutions, however the large number of participants in the construction industry means that the data involved are complex, and problems arise related to volume, heterogeneity, and fragmentation. Thus, the sector lags behind others in the adoption of e-commerce. In particular, data integration has become a barrier preventing further development. Traditional e-commerce platform, which considered data integration for common product data, cannot meet the requirements of construction product data integration. This study aimed to build an information-integrated e-commerce platform for industrialized construction procurement (ICP) to overcome some of the shortcomings existing platforms. We proposed a platform based on Building Information Modelling (BIM) and linked data, taking an innovative approach to data integration. It uses industrialized construction technology to support product standardization, BIM to support procurement process, and linked data to connect different data sources. The platform was validated using a case study. With the development of an e-commerce ontology, industrialized construction component information was extracted from BIM models and converted to Resource Description Framework (RDF) format. Related information from different data sources was also converted to RDF format, and Simple Protocol and Resource Description Framework Query Language (SPARQL) queries were implemented. The platform provides a solution for the development of e-commerce platform in the construction industry.

With the development of information technology, many industries have greatly improved their production efficiency. At the same time, production efficiency in the construction industry has not only failed to grow, but is actually on the decline. The main reason for this problem is interoperability, which is the exchange and sharing of construction project information between the participants and the different application software in the project life cycle. At present, Building Information Model (BIM) is considered to be an effective way to solve the problems in the construction project life cycle. The integrated BIM information is a significant improvement in all processes where project participants have to use and communicate complex, accurate and interrelated construction project information. This paper first expounded the background, which is during the construction project life cycle management. The degree of information sharing and collaboration of construction units is low, which is the main reason for low efficiency in the construction industry. Then, a BIM-based information integration model is proposed. The information interchange of construction units is realized in this model. The efficiency of project management is improved.
