- the government strategy

4. The information revolution
• More than 30 billion items are shared by Facebook every month
• Data production will be 44 times greater in 2020 than 2009
• In 2015 20% of data produced will live in or pass through the cloud.
• Before 2003, 5 exabytes of information had been generated, this amount is now
created every two days.

8. • Focused towards the information needed to represent a building and its
components in 3D.

11. Challenges

12. Avoid Information Overload
−Focus on the information you actually need.

13. http://www.bimtaskgroup.org/

18. Information – the government strategy
• By April 2016 - All centrally procured projects to achieve Level 2 BIM.
- move from just geometry to 3D geometry AND the information behind it
- level 2 BIM - a managed 3D environment with data held in separate BIM
tools.
- information collected digitally at various stages of a project.
• Digital geometry + Digital information in an open standard (COBie).
(Level 3 BIM is a single BIM model created through integration of the
information in all BIM tools.)

19. BIM progress
• Early adopter projects underway.
• Reported savings so far of 18%
• Roll out of BIM to other central departments.
• For the MOJ BIM is becoming ‘business as usual’
• Focus is now on BIM implementation.

20. Agenda
1. Information
2. Information
3. Information
- the government strategy
- classification
- beyond level 2 BIM

21. Classification
The purpose of a classification:
−Information can be found and retrieved very easily.
−The rules (its taxonomy) are easy to understand and apply.
−Information can be added following these rules to ensure it appears in
the correct place.
−There is ideally no limit to the information that the classification can
accommodate.
−Information can be referenced.
−Information is maintained.

22. Uniclass
• First published in 1997
• Created by CPIC

23. Uniclass
Difficulties with current version
• It’s out of date
• Tables are not aligned to one another
• Inconsistent approach
• Inconsistent coding
• Doesn't support BIM, the project timeline or the draw-
specify, design-document approach.

24. Uniclass 2
ISO 12006-2

25. What can Uniclass 2 do for you?
−Arrange information about a particular topic
−Coordinate and disseminate information
−Find and understand information
−Join like information together

30. Beyond Level 2 BIM – What are the information Challenges
• Terminology
 Properties, attributes and names vary and can not be reliably
exchanged across different platforms, disciplines and jurisdictions.
• BIM content needs to be
 Open
 Accessible
 Standardised
 Structured
 Controlled and understood

31. Challenges
• Product information
 Inconsistent
 Generally incompatible with BIM
 Difficult to review, compare, update and share digitally
• Classification of information
 Different countries use different classifications
 Different classifications aren’t connected

• Independent
• Open
• Not for profit

naming of things.

49. Summary
• BIM is moving fast in the UK.
• High quality digital information that is structured and
connected is the future.
• Collecting and connecting information in an open accessible
manner enable comparison, analysis and review.

50. Summary
• Digital information will be used exclusively for electronic
transactions.
• Data is moving from collection to connection
• Information will become insight
• Analysis will become prediction
• Early adopter project success so far indicates that the UK is
on the right track.

51. And the UK is leading the way
