3D Visualization of Sub-Surface Pipelines in Connection with the Building Utilities: Integrating GIS and BIM for Facility Management

Buildings cannot be used for their intended purpose without utilities. Maintenance workflows require work to be performed from the inside and outside of the buildings. The inside information can be extracted from a fully built building information model, and the outside information can be extracted from a Geographical Information System (GIS) map. GIS is the platform that integrates maintenance workflows for mechanical, electrical and plumbing systems for facility infrastructure. In order to perform efficient maintenance work, it is necessary to get the related information of the pipe network in advance. The purpose of this paper is to investigate how to use GIS and BIM information to get the detailed information for facility operation and maintenance. Field workers, without strong GIS and CAD background, need to visualize and analyze the subsurface pipelines. This study proposes a method to use data from BIM and GIS for 3D visualization.
