为了应对建筑环境可持续管理和发展的挑战，工程师和设施管理人员需要利用近年来发展起来的3D城市模型，以包括内部空间。促进与这些3D城市模型交互的一个关键问题是将3D BIM集成到地理空间环境中的能力。这需要使用专门的软件和专门知识。为了简化这一过程，我们在这里提出了一个信息系统，便于使用BIM进行地理分析。BIM 4GeoA是一个将现有开源软件和开放规范相结合的概念，用于在其边界范围内对建筑信息进行有效的数据管理和分析。核心组件包括空间数据库PostgreSQL/PostGIS、建筑信息服务器、工业基础类（IFC）、Google Earth 3D查看器和现有的3D OGC标准（KML、CityGML）。本文介绍了用于使这种新的专家系统的开发应用到三维Web GIS的背景下的过程。对这些不同组成部分的优点和缺点进行了彻底的分析，以利用其优点并克服其缺点。该系统架构在操作上用于开发不同的应用程序，用于大学校园的管理;提供了一个很大的潜力，为设施管理部门的业务任务，如公用事业基础设施，以及公共社区（学生，工作人员），如路由应用程序，搜索一个人与定义的标准。
To address the challenges of sustainable management and development of the built environment, engineers and facility managers need to exploit the 3D City models which grown in recent years to include interior space. A crucial issue for facilitating interaction with these 3D city models is the ability to integrate 3D BIM into the geospatial context. This requires the use of specialized software and specific expertise. In order to simplify this process, we here propose an information system that facilitates the use of BIM for geo-analysis purposes. BIM4GeoA is a concept for combining existing open source software and open specification for efficient data management and analysis of Building Information within its boarder context. The core components are the spatial database PostgreSQL/PostGIS, the building information server, the industrial foundation class (IFC), the Google Earth 3D viewer, and the existing 3D OGC standard (KML, CityGML). This paper presents the procedure used to enable the development of this new expert system as applied to the context of 3D Web GIS. A thorough analysis of the strength and weakness of these different components has been undertaken to employ it is strength and override its weakness. The system architecture is operationally used in developing different applications for the management of a university campus; a large potential is provided for operational tasks of facility management department, such as utilities infrastructure, as well as public community (student, staff) like routing application, searching for a person with defined criteria.
