A study on data interaction among different levels of detail in planning phases for mega projects

Urban renewals in an area or district consist of multiple facilities construction projects, and thus, should be managed as a program. Successful program management is enabled by seamless information of subprojects during its whole lifecycle. In the aspect of data management, program is differentiated with project by its own management structure. Specified architectural design data of individual facilities become the source of program management as a project developed into architectural planning phase and even further, while the schematic data on program created in planning phase contain directions to plan individual facilities in the area. For this reason, the authors suggest schema of data interaction in the planning phase from the very initial planning phase to subsequent detailed planning phases. The data interacts based on product models of different management levels and different levels of detail (LOD), which is commonly introduced as BIM (Building Information Model) in architecture, engineering, and construction industry. Based on the advantages of BIM, the suggested data interaction schema is expected to bring managerial opportunities such as instant cost estimation on with its own management structure of megaproject and with data that are required for specific management activity.
