Abstract
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.
Highlights
Industrialized construction is superior to traditional construction, as it reduces construction time and labor requirements [1,2], ensures building quality and work safety [3], and improves environmental sustainability [4]

Summary
Industrialized construction is superior to traditional construction, as it reduces construction time and labor requirements [1,2], ensures building quality and work safety [3], and improves environmental sustainability [4]. The main steps for industrialized construction are off-site manufacturing, transport, and construction site assembly of building components. To reduce costs and time taken, and to offer customization, mass customization is employed. Mass customization represents a method and technologies through the whole process of marketing, commodity development, production, and delivery [7]. Mass customization can customize goods or services for individual customers in high volumes at low cost [8,9,10]. It is a prerequisite for industrialized construction procurement (ICP). ICP methods need to be improved through the adoption of an information management and communication platform
