4. Just to be sure, that we are on the same side …
• Digital Building Model
– (Building Information Model, Virtual Model, …)
– Data schema
• Describes geometry, properties and relationships of buildings and
their components
• Supports storing, sharing, exchanging of digital building information
– Cumulated information about a building
• BIM – Building Information Modeling
– Integrated building life‐cycle process
– Supported by a digital building model
– Create & manage building data
– Team‐oriented working processes

5. Definition of integrated BIM
Integrated BIM means
• Improved
– collaboration,
– Communication
– and decision support
• enabled by
– horizontal
– and vertical
integration of data,
• and information
management
– in the whole value
network
– throughout the
building lifecycle.

6. To BIM or not to BIM?
• Is BIM an overrated phenomena to a paradigm shift?
• Do we need a paradigm shift?
• If we need a paradigm shift:
– What do we need to shift?
– Where to start?
Prof. Rasso Steinmann Institute for
Okt. 2012 6
Applied Building Informatics

7. The shift in Automotive Industry 20 yrs ago
• The Carnegy Mellon augury some 20 years ago:
– “The German car industry will fade away in a couple of
years”
• => Main lessons learnt:
– Reduction of in‐house production depth
– Digitalization of information
– Standards for data‐exchange with partners
– => Total new processes in design, production, logistics
Prof. Rasso Steinmann Institute for
Okt. 2012 7
Applied Building Informatics

8. And the Building Industry?
• Yes we have …
– Innovations in production and materials
– Pre‐fabrication (but only to a certain extend)
– Online workspaces
• But basically …
– We are still communicating like the pharaohs some 2000
years ago
– We have digital data, but we use them only as digital
documents
• This is faster
• But still quite stupid
– => we are going on to delete information before we exchange it

9. How can we share what we think?
Is there a better way than 2D‐plans and text‐documents?

is such a Semantic Product Model

13. BIM‐Situation in Germany
• Some Key‐Players adopted BIM
– Some large Contractors
– Some authorities
– Some innovative architects and
consulting engineers
• Contra‐productive
– HOAI (German fee structure for arch.
and eng.)
• However: International impacts • New approach together with
– International building owners
contracting in Germany
• Key BIM‐Technology comes from
Germany
– Basics of IFC came from Germany – BIM‐Bau: Advisory Committee
– BIM‐Software available since 25 years • Chambers of Architects and Engineers
– BIM‐Middleware solution was available • Building Associations
already 10 years ago • Building Software Association
– Technical experts are available • buildingSMART
– Pilot Projects

14. Industry leaders are convinced, e.g.:
Patrick MacLeamy, CEO HOK, Chairman buildingSMART
This is
important!
We need to
change industry!

15. BIM is today
• Key‐Players are already doing it
• Following slides, already some years old

16. e.g. Some BIM/IFC projects of Finnish Senate Properties
HAKA6
Lohipato school
All
Aurora 2
participants
used BIM HUT-600 Helsinki Music Centre
Tietotalo 2, Oulu TUT Administration
Upinniemi Central Warehouse
As the result of testing
Torikatu 36, Oulu Didacticum Senate Properties
HU Animal Hospital announced in 2006 that
VTT Digi Building they will demand BIM in
Only one all projects starting on
participant Canthia October 1st, 2007
used BIM
BIM used only in one BIM used in all
phase of the project phases of the project

handover to FM
new extension based on Data handover in IFC
architectural competition

Software: ArchiCAD FM Data – IFC from ArchiCAD to CAFM Morada
Prof. Rasso Steinmann Institute for Applied Building Informatics

31. Where is the budget for BIM?
• The overall project costs
– Remains 100 %
– may not be increased for BIM
• Only very, very few building owners are able to understand
the need for BIM
• Quality improvement by BIM is not yet well understood
• => The budget has to come out of savings in the
project
– Reduce errors
• Bögl: “Errors on construction sites are much more expensive
than BIM and BIM‐Managers.
With BIM we can save 20%‐30%”
– Savings in workload
• Have to be shared in the consortium
– Biggest impact on total costs is in the early design
phases

32. Let’s talk money:
New fee diversification for BIM in budget for planning
Fee diversification, up to now 100%
Basic evaluation
Preliminary planning
Outline planning
Approval planning

38. Lessons learnt form automotive industry:
The product model is evolutionary
=> Data Synchronization and Consolidation at certain milestones
Something like this seams to be more realistic
