Research on information models for the construction schedule management based on the IFC standard

摘要

Purpose: The purpose of this article is to study the description and extension of the Industry\udFoundation Classes (IFC) standard in the construction schedule management, which achieves\udthe information exchange and sharing among the different information systems and\udstakeholders, and facilitates the collaborative construction in construction projects.\udDesign/methodology/approach: The schedule information processing and coordination are\uddifficult in complex construction projects. However, Building Information Modeling (BIM)\udprovides a platform for exchanging and sharing information among information systems and\udstakeholders based on the IFC standard.\udThrough analyzing the plan, implementing, check and control, the information flow in the\udschedule management is reflected based on the IDEF0. According to the IFC4, the information\udmodels for the schedule management are established, which not only includes the each aspect\udof the schedule management, but also includes the cost management, the resource\udmanagement, the quality management, the risk management and so on.\udFindings: The information requirement for the construction schedule management can be\udsummarized into three aspects: the schedule plan information, the implementing information\udand the check and control information, and three aspects can be described through the existing and extended entities of the IFC4, and different information models are established\udrespectively.\udOriginality/value: The main contribution of the article is to establish construction schedule\udmanagement information models, which achieve the information exchange and sharing in the\udconstruction project, and facilitate the development of the application software to meet\udrequirements of the construction project.
