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.
