Demystifying COBie Standards and how to integrate them into BIM
John Sullivan (concepts)
COBie-construction operations building information exchange (allows professionals to explore a project’s key physical and functional characteristics digitally-before it’s built.
-internationally recognized data exchange standard
-exchange building systems information between design and construction with building owners
-format for delivering construction handover data
Revit COBie Tookkit
-template and tools that collect COBie and passing it on
-Facility info and contact info
-spatial information
-building components
HOW design team use COBie
-coordinated, consistent information is used to:
- design
- visualize, simulate, and analyze
- document
- deliver
Contains model elements
- doors
- walls
- windows
- rooms
- equipment
Element definition
- graphics
- attributes/properties
- relationship to other elements
5 ways your project will benefit from BIM
BIM is idea of modeling a building before constuction
BIM-to optimize the building process
BIM execution planning BIM PXP-optimize BIM project
Who will do BIM work
What BIM work will be done
When BIM will be used
Why BIM is being used
1. roles and responsibilities (clarify who’s doing what)
-who’s in charge
-manage a federated model
-accountability
-who to invite to this meeting
-time zones
-avoid duplicate work, rework
2. determines level of detail
-AIA E202 Documentation (defining level of detail)
-who’s responsible for what?
-gives team a reference
-don’t overstate capability
-“ideally, we’ d model everything”
-avoid misunderstandings
3. clear up milestones and dates
-know your target dates (gives something to measure the progress)
-accountability
-level of detail leads to schedule improvement
-provides reference and accountability
4. Improve your RFI Process
-reduce the number of RFIs
-RFIs get more focused-better
-more pertinent questions
-helps team”speak the same language” (misunderstandings between designer and contractor)
-May have more, not fewer RFIs ,but it can open a dialog
5. Potentially Reduce Project Cost
-all parts of the BIM PXP lead to improved results (accountability to finish on time)
-creates known quantites
-a lot of field rework gets reduced
-avoids work stoppages/changes
-insurance policy-risk reducer
