This study proposes a process that constructs 793 KBIMS libraries using a cloud-based platform and overcomes the limitations of BIM data compatibility through a unique property conversion technology using ASCII codes.
ABSTRACT
This study presents a method for constructing a BIM library containing architectural and structural member geometry and property data applied with KBIMS, and a method for converting to KBIMS IFC files by resolving issues in the property data conversion process.
Although various BIM tools are utilized in projects, library research has largely relied on specific tools; this study utilized CATIA V6 embedded in a cloud-based database integration platform to develop libraries for a total of 793 architectural and member geometries and dimensions across 12 major categories.
The study identified database input restrictions caused by data types and special character property names during the KBIMS IFC property input process. Usable data types were identified and entered, and an alternative input method using ASCII codes for special character property names was developed.
A prototype converter was developed to convert the extracted IFC files back into IFC files containing the original KBIMS property names, which was then verified using a pilot model. The results of this study will help expand the range of choices for BIM tools when applying KBIMS in actual projects and reduce project data compatibility issues.
Finally, for the continued utilization of the KBIMS library, discussions on maintenance and management strategies among relevant organizations are necessary.
