5. What’s BIM?

6. 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”
BIM Definitions
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.”

What’s BIM?

9. BIM – A Change to Process
”MacLeamy Curve” Patrick MacLeamy , CEO, HOK

10. “The number of construction professionals using bim (building information modelling) has
jumped from 13% to 31%, according to the results of the NBS’s annual bim survey.
Of the 1,000 respondents to the national survey, almost 19 out of 20 expected
to be using bim within the next five years;
80% of those who had already adopted bim agreed that it increases the coordination of
construction documents; while 65%said it delivered cost efficiencies.
Why BIM?
Bim adoption more than doubles

11. • 2D communication in a 3D world
• Traditional problems
• Sustainable design and energy performance compliance
• Building performance regulation
• Waste within construction
• Latham / Eagan Reports
• Best practice
Why BIM?

12. Government Construction Strategy
• 20% reduction in costs targeted for UK construction
procurement
• BIM confirmed as an essential element in the reduction
waste within construction.
• BIM working party strategy published June 2011.
• Begin phased roll out to all government projects from
summer 2012
• Introduction of Construction Operations Building
Information Exchange (COBie 2.4)
• All UK public funded construction projects will require
fully collaborative 3D BIM (level2) as a minimum by
2016.

13. BIM Levels

14. BIM Technology – Architecture
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

15. BIM Technology - Consumer (3D-5D and beyond)

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

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

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

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

20. BIM Development
BS 555

21. BIM Awareness

22. Government has given BIM a big boost, but;
• Currently still Confusion
• 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
BIM -Currently

23. BIM Definition
Chuck Eastman, The BIM Handbook
…“an intelligent simulation of architecture.” To enable us to achieve integrated
delivery“
BIM alone fails to achieve Level 3 objectives.
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)
iBIM / Integrated Project Delivery (BIM Level 3)

24. • Only Suitable for Large projects?
• Just 3D CAD?
• Can’t Do refurbishment?
• Costs too much?
• Takes too long?
• Doesn't Suit Our Process?
BIM POSSIBLE?

25. Project Examples – Oldham BSF
Oldham BSF: North Chadderton School & Sixth Form
Contractor: Balfour Beatty
Value : £20m
Consultants:
Clarke Bond (SE)
RPS Group (M&E)
Arup (Fire)

26. Advantages
• BIM Implementation project
• Single source of information – Co-ordination
• Ability to adapt design during all stages
• Able to produce drawn information quickly
• Automated schedule / take off
• Worksharing environment
• Contractor using BIM for Co-ordination
Disadvantages
• Consultants were not using BIM
• Software learning curves for design team.
Project Examples – Oldham BSF

27. Advantages – 3D Environment & Rendering
Project Examples – Oldham BSF

28. Project Examples – Kearsley Academy
Contractor : BAM
Value: circa £10m

29. Project Examples – Kearsley Academy

30. Project Examples – Kearsley Academy

31. • Grade 2 Listed
• Refurbishment & Extension
• ty+ Rombol (Gifford)
• Lonely BIM(s)
Proposed Image (3Ds Max)
Existing Market
Revit Model View
Project Examples – Chesterfield Market

32. Project Examples – Housing Team

33. • 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
BIM – Implementation

34. • Improve design quality
• Improve communication
• Single source of Information
• Increased collaboration with partners
• Reduction in waste
• Opportunities for re-use of data post construction
Summery- Why use BIM?

35. The introduction of BIM is not about the adoption of any software; it is probably
the most significant change process you will ever make
Conclusions
• Industry is developing 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 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

36. Questions?
Darlington top 5
• How will BIM effect construction SME’s ?
• What support can the government offer SME’s (training and education
being a priority)
• What software tools are appropriate for BIM in a contracting environment?
• Will all sub-contractors to the main contractor be expected to use BIM
tools? If they don’t have them – how will the main contractor share
information?
• What is the cost of up-skilling and ‘tooling up’ in readiness for BIM?
• How quickly will businesses see a return?
