Integrating BIM for DES-based resource scheduling

Abstract

Due To The Complexity Of Construction Projects, Building Information Modeling (BIM) Has Been Put Into Use At Present And Can Be Seen As The Data Base For The Digital Twin (DT) In Construction Industry. One Kind Of DT Is Discrete Event Simulation (DES) As A Proven Tool To Build Up Complex Systems For Calculating The Optimum Scenario. With Increasing Data Collection On-Site, BIM And DES Can Be Used Not Only For Planning But Also For Decision-Making During Execution. Today, DES Is Not Used In Practice Due To High Efforts To Set Up And Update A Model. The Paper, Therefore, Presents A Methodology For The Integration Of BIM In DES. The Focus Of The Paper Is The Heavy Civil Engineering Where Only a Few Efforts Is Put Into BIM And DES. An Overview Of Existing Standardized Data For BIM And Telematics Data Is Given. Furthermore, Currently Available IFC Software And Libraries Are Applied To Implement An Appropriate 4D Model Following The BuildingSMART Standards Of Industry Foundation Classes (IFCs). Finally, A Case Study Is Used To Validate The Method.
