The document discusses the emergence of 3D digital cities as a convergence of building information modeling (BIM), computer-aided design (CAD), and geographic information systems (GIS). 3D digital cities combine mapping, building, civil, and utility data into accurate 3D models that can be visualized, analyzed, and shared. They are part of municipal sustainability initiatives and help analyze projects, visualize designs, and simulate city planning initiatives. The trend is moving towards more detailed real-time navigation and analysis of intelligent 3D city models.

30. What is the Value of BIM to an Owner (PWGSC)?
 Integrates fragmented and duplicated information between stakeholders
 Incorporates facilities management into coordinated database
 Verifies that information is accurate, concise, and measurable
 Leverages data as an asset for streamlined life cycle management
 Accommodates future government priorities and reuse of data (models provide
relevant computable information for many potential applications)
 Allows more time for value-added tasks (e.g., design iterations, building performance
schemes, etc.)
 Provides opportunity for analysis and validation of information
 Leads to informed choices about sustainability and energy performance
PWGSC will enhance its future potential as a service provider and owner of assets, while
departmental processes will benefit from reduced errors and redundancy.
