Abstract: Traditionally, operation and maintenance information for MEP mainly comes from completion data in the forms of drawings or documents.When the information is needed, it requires manual searches from such a huge amount of paper files.In order to realize the information transmission from design and construction phases to operation and maintenance period, effectively organization of such information by electronic means is the key issue to be resolved in current building lifecycle management.This can also enhance the information-aided maintenance.By introducing Building Information Model (BIM) and two-dimensional code, a BIM-based Facility Intelligent Management System (BIM-FIM 2012) is developed to realize the electronic integrated delivery of MEP, and to improve the maintenance management and emergency management of a building during its operation and maintenance period.The system also provides an effective way and platform to ensure the safe operations of all MEP systems.
