How BIM and GIS integration is critical to achieve a digital twin capability for the Department of National Defence

The Department of National Defence, as steward of a real property (RP) portfolio that includes tens of thousands of buildings and supporting infrastructure, is seeking to manage its Real Property (RP) assets more effectively by modernizing and improving its digital capability. In this effort, interoperability between BIM and GIS through open data standards is crucial to enable the Integrated Digital Built Environment. BIM allows representation of detailed information regarding building elements while GIS allows representation of spatial information about buildings and their surroundings. Overlapping these domains provide support to important activities such as construction and maintenance, and sustainable urban design.
