The Calgary Cancer Centre is a $1.2 billion cancer research and treatment facility in Calgary, Alberta. PCL led the team in creating an as-built BIM complete with asset information as a resource to support the owner in their post-construction facility management workflows.
From the earliest stages of the project, Alberta Health Services and Alberta Infrastructure (“the Province”) saw the value of Building Information Modeling (BIM) as a way to “deliver high value in quality, timeliness, cost and to maximize building performance during operations.” The ultimate goal was to “provide a fully integrated, coordinated and site verified as-built model complete with facility management related information of all maintainable building elements in a form appropriate for use by the Province’s end users throughout the life of the facility.”
Here are some challenges encountered:
The solution comprises two parts: the as-built BIM and asset information management.
A thorough 3D BIM coordination process involving MEP services, structure, interior, and envelope scopes helped identify and resolve tens of thousands of issues early and prevented them from happening on site where they could cause delays to the schedule or escalate cost. Layout information was given to field crews via installation drawings and survey data generated directly from the coordinated model. Completed site work was then verified against the coordinated model using as-built survey points, drone photography, 360° photos, and laser scanning. The model was updated with any differences to produce an accurate and complete as-built BIM.
The AIM scope was clarified early and documented in a BIM and AIM Execution Plan. It was critical for the owner and facility management teams to identify which assets (pumps, boilers, electrical panels, etc.) and data points (location, manufacturer, serial number, etc.) needed to be included in the as-built BIM and COBie file.
Asset information was generated throughout various project stages; from early design to final commissioning. Establishing workflows early helped ensure data continuity as it was created and passed through various applications. BIM and AIM schedule activities were integrated with the master schedule to clarify dependencies and create accountability. Progress was tracked through a spreadsheet that referenced reports exported from the various applications that were used. Interim model and COBie file submissions to the Province gave them the opportunity to perform reviews and test interoperability with their systems.
