As a pillar, the construction industry in China specifies a schedule control in project operation phases which matters project cost, materials and security. Unlike general construction projects, the chemical production and construction processes have an awfully cumbersome management for the field schedules such as fire protection and hydropower installation. This paper takes the chemical construction project PVC complex as an example, analyzes the application of BIM technology in the schedule management of the whole construction project. The findings show that the BIM technology implemented with the Revit platform, Project platform and Navisworks software can improve the field construction efficiency in the operation phase of the PVC complex construction project by the schedule management, reduces labor and time costs, shortens the construction period, and improves the work efficiency of project managers. This study provides the important clues to the development of chemical construction industry towards industrialization and modernization.
