1 Overview
BIM on GIS project overview
To realize BIM on GIS technology for productivity of AEC industry, we should have some questions like these.
Questions Research and try to
• What is the benefit from the fusion • find the useful use-cases between BIM and GIS as the viewpoint of the public sector • define the technology and the organization • What do we should do first? including people etc • What is the barrier to realize it? • survey the issues and define the considerations • How to develop it? • collaborate and research it with the institutes and the industries

Lesson & Learn
Lesson & Learn
• To obtain the user satisfaction, the pilot system using the standard file format MUST ensure
• the scenarios about the use-cases to realize the business value ex – interview with the owner or the user
• the data process performance (they disliked the low speed) ex – lightweight format using the LOD, the compression strategy like JT format
• the data exchange between the heterogeneous system (they disliked the missing data or the low information compatible between the commercial system) ex – ETL
