description
With urban populations expected to double by 2050, an increasingly urgent need exists for implementing sustainable urban design and infrastructure rehabilitation initiatives. Digital 3D models of our urban infrastructure form part of the solution as engineers, architects and geospatial professionals collaborate and share information across the infrastructure lifecycle. This presentation explores the reasons behind developing such a model and examines the convergence of the information and technology needed to make it real such as Smart Infrastructure Modeling (SIM), CAD, GIS and BIM. Demonstrations and plenty of eye-candy will be used to highlight the benefits. The presentation concludes with an examination of today’s trends and future opportunities as they relate to the emerging digital cities phenomena.

Policies and Actions
Complicated problems require new
ways of thinking and new tools
Build partnerships with climate
leaders, abandon the skeptics
Long term policies can be attained
through repeatable processes
Refurbishments and Shovel Ready
Projects can be starting points

BIM is Now
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.
