We have been honored to be asked by the International Facility Management Association (IFMA) to write a white paper entitled "GIS for Facility Management". This is the third chapter in the series. A full copy of the paper can be downloaded from the IFMA web site. We would like to thank Manhattan Software and ESRI for their support of the white paper.
GIS for Facility Management - Chapter 4
For years, facility managers have been using GIS at the landscape level to manage a number of the assets in their facility portfolio. Some of the earliest applications of GIS in facility management were related to pavement management at airports, municipal water and wastewater infrastructure, and electric utility distribution. For example, facility managers of the US Air Force have developed a standardized set of GIS layers to support the management of Air Force bases.

The spatial data that exists in a facility geodatabase has often been developed from aerial imagery or global positioning systemenabled (GPS) field data collection practices. The limitation of these data collection techniques is that they are blind to building interiors. Aerial photography cannot see through the roof. GPS signals are not available inside buildings. The result of these constraints has been that significant holes have developed in the rich geospatial data fabric that describes our facilities. These holes correspond to our most concentrated financial investments and the places where people spend most of their time – inside buildings.
Today, it is becoming possible with GIS to think about and analyze the spatial aspects of every component of facility management workflows to decrease cost and increase productivity. None of
GIS is a platform that supports the integration of information from all of these spatial, temporal and informational dimensions. Examples of such integrations include:
4.1 Spatial Data Infrastructure for Facilities

Once this basic data has been added to the GIS, it is possible to provide geospatial support to a wide variety of information systems and business processes for the facility management community:
In order to provide best practices guidance and support for facility managers interested in establishing facility GIS capabilities, an independent committee made up of software vendors, government users, higher education facility managers and facility managers from various levels of government formed the Building Information Spatial Data Model (BISDM) committee in 2007. This committee has published several versions of the Building Information Spatial Data Model and continues to enhance and extend the model and its tools, making them available to the community. A diagram of the conceptual BISDM is shown in Figure 3.
