4. BIM Definitions
Charles (Chuck) Eastman, The BIM Handbook
…“an intelligent simulation of architecture.” To enable us to achieve integrated
delivery, this simulation must exhibit six key characteristics. It must be:
(a) Digital,
(b) Spatial (3D),
(c) Measurable (quantifiable, dimension-able, and query-able),
(d) Comprehensive (encapsulating and communicating design intent, building
performance, constructability, and include sequential and financial aspects of
means and methods),
(e) Accessible (to the entire AEC/owner team through and interoperable and
intuitive interface, and
(f) Durable (Usable through all phases of a facilities life).

5. BIM Definitions
BS ISO 29481-1 2010 - Building information modelling -
Information delivery manual
“Shared digital representation of physical and functional characteristics of any
built object (including buildings, bridges, roads, etc.) which forms a reliable basis
for decisions”
CPIC /RIBA – Proposed Definition
“Building Information Modelling is digital representation of physical and
functional characteristics of a facility creating a shared knowledge resource
for information about it forming a reliable basis for decisions during its life
cycle, from earliest conception to demolition.”

10. BIM Advantages - General Benefits
• Enhanced Design
• Greater Productivity
• Improved Delivery

11. BIM Advantages – Designers
• Conceptual design
• Central Source of information
• Multi-Discipline Integration
• Early detection of conflict

12. BIM Advantages - Construction
• Pre-construction assessment
• Reduction in no. of RFIs
• Fewer field coordination issues
• Quantity/cost tracking improvements
• Greater potential for off-site fabrication
• Reduce Risk

13. BIM Advantages – FM Advantages
• Asset management
• Facility maintenance and operation
• Life cycle of buildings
• Single Source of Information
• BIM virtual building and FM Software synchronisation

14. BIM -Reality
• BIM seen as an obstacle not an enabler
• We are adapting BIM to fit current practices
• ‘My’ BIM
• Varied Adoption
• Software collaboration needs to Improve
• Definition of BIM is not important it is about understanding what BIM
Enabled Technology can do for you.
• We need to understand BIM Better

15. BIM Enabled Technology – ‘Architecture’ BIM
BIM technology is being developed by a range of major CAD vendors
but is represented by three main staples for Architecture;
Revit Suite
NavisWorks
Grahisoft Archicad
Vecterworks
All-Plan
Microstation
Bentley Architecture Many More BIM packages for
Environmental and Structural
analysis

16. BIM Enabled Technology – Choice
NBS Survey 2010 – Current Primary Drawing Tools

17. BIM & Revit Architecture

29. iBIM / Integrated Project Delivery
BIM Definition
Chuck Eastman, The BIM Handbook Circa
…“an intelligent simulation of architecture.” To enable us to achieve integrated
delivery“
BIM alone fails to achieve a truly Common Shared Environment
Only when we have a proper working understanding of BIM will we be able to
begin the next step of integrated BIM (iBIM) and Integrated Project Delivery (IPD)

30. iBIM /IPD Overview
CPIC - Construction Project Information Committee –
2010 BIM Workshop - Principles of CAD evolution Levels 0-3

31. Conclusion - Why use BIM?
• Improve design quality
• Improve communication
• Single source of Information
• Co-ordination
• Increased collaboration with partners
• Reduction in waste
• Opportunities for re-use of data post construction
• Future Possibilities

32. BIM – Implementation
• Planning Implementation Is key
• Develop a sound, comprehensive implementation strategy,
• Assemble the right team,
• Select a suitable starting project
• Understand the learning curves
• Understand Cost and Benefits to business
• ROI –calculators
• Hardware requirements

33. Conclusions
• Industry needs to establish a clear best practice with BIM
• More Open about current BIM adoption
• BIM definition is not important it is about understanding the benefits of a
BIM Enabled Environment
• Once we are BIM enabled then we can move to Social and iBIM
• Working procedures need to adapt to enable iBIM/IPD
• Real risk that not having BIM experience could exclude you from future
projects
The introduction of BIM is not about the adoption of any software; it is probably
the most significant operational change process you will ever make
