Integrated education
for integrated design -
teaching BIM to
Architecture and Civil
engineering students

Current status in Germany
Best construction products
Outstanding engineers
Excellent handicraft business and
construction companies
Paradox of the construction industry:
Despite the high quality there are noticeable
problems in many construction projects!

Are we in the AEC trying to reach individual targets or a common one?

Which problems have to be faced in
the construction industry?
Planning/Design
o Missingcommunicationbetween involvedparties
o No direct costs-feedbacks duringplanning-decisions
o Unstructured,heterogeneousinformation
Execution
o Missing or inaccuratedesign information
o Inadequate quantities
o Rigid and inflexiblecosts- and timeplanning
o Quality control basedon inadequateinformation
o Frequentinterruptions
Operation/Use
o Insufficient as-builtdrawings andprojectdocumentation
o Renovation,upgrade anddemolition planningis time-consumingand difficult tocalculate(unpredictableconstraints)

Meaning of the acronym BIM
Building Information Modeling (BIM):
• Is a digital representation of the physical and functional properties of a h2h betting tips construction.
• Is a common source of knowledge for information about a
system, as a reliable basis for decision-making during its
life cycle; since the early design until demolition.
Short definition of BIM:
Life cycle management of the built reality,
supported by process modelling and digital technology.
(NBIMS – National BIM Standard – United States)

Summarizing the potentials
• Complete knowledge for:
• Owner (marketing)
• Planner
• Execution companies
• Operator (reconstruction, demolition)
• Representation of complex relationships
• The entire project documentation (lists,
evaluations, analysis, ...) will be in all phases
automatically updated!

BIM in Germany – Current status /
Outlook In an international comparison the German construction industry is a step
behind concerning BIM implementation. Possible reasons for this are:
• Language barriers (English)
• Limited experience with high-quality work in 3D
• Fragmentation of the German construction industry
• Some parties involve in planning have no advantage because of the
German “Free Structure for ACE”
• Investigated pilot projects reveal inadequate results
• Basis’ understanding and skills are missing trained staff will be
required in order to increase the quality of the exchange
Current impulse:
• Selective promotion from the public authorities
• The federal government shows its support in the „Digitale Agenda“
• Federal associations face the big challenge
Seite 11
Political impulse in Germany
• Reform commission
• The aim is “Open BIM” for buildings and civil constructions
• Digital Agenda 2014 – 2017
• Federal government’s High – Tech strategy
• Publication: “BIM-Leitfaden für Deutschland” (BIM-Guide for Germany)
• „Maßnahmenkatalog zur Nutzung von BIM in der öffentlichen Bauverwaltung unter Berücksichtigung der rechtlichen und ordnungspolitischen
Rahmenbedingungen“
Seite 12
Reform commission for large-scale
project building
Task force „Moderne IT-gestützte Planungsmethoden (BIM)“
• Aim: Improve transparency of building projects’ planning and
development.
Cost Certainty and increase of the efficiency in the
construction industry
Construction quality improvement
Optimization of the ecological characteristics, CO2 reduction
Improvement of the position of German planners and the
German construction sector (incl. German construction
suppliers) in the international market
• Time horizon: implement an integrated model-oriented approach
in large-scale projects during the next 5 years

and many more…
Seite 14
Specific objectives of the Planen
Bauen 4.0 GmbH
• Design the digitalization of the entire construction value
chain over the whole life cycle of the facilities and draft
planning of the implementation and operation until
demolition and recycling
• Setting-up and running a national platform for BIM
• Development of requirements, standards, behavior
patterns and guidelines for BIM
• Generate, relate and communicate the Know-how in the
field of digital building and BIM

Who looks for a BIM manager?
Seite 27
What do we have to do?
• Standards and guidelines have to be developed
• The knowledge and the correct use of BIM has to be encouraged education and training
Universities
Companies
Professional associations • Reference projects must be supported and encouraged
• Certification for quality asssurance (Software, products, services, staff)
• Integrative information and services must be provided
• Specific public relations with events and training
Seite 28
Conclusion
The importance of BIM growing continuously,
however in Germany we are still at the beginning.

IFC development and implementation
Source: “Open Standards for BIM” | buildingSMART Canada
IFC2x3: current common version
IFC4: published, but not consistently
available
Status Quo:
Use of
proprietary
exchange
formats
(companies-
related)
The consistent
use of IFC is
still
problematic
Seite 34
Summarizing the potentials
• Digital building model enables:
• Consistent use of building information
in all phases Life cycle management
• Analysis and simulations
• Higher costs- and time planning accuracy
• Lower coordination errors
• Higher planning- and execution quality
through clash detection and alternatives
comparison before starting construction.

Response of the market
• Public buildings management association, regions and
municipalities No use
• Planning companies Mainly used by large-scale companies
• Executive companies Occasional use of BIM in construction projects (corporate strategy!)
• Software companies Growing IFC-based applications, e.g. for the bill of quantities, costs
estimation, constructability, building simulations (energy, fire, ...), integration of construction-related knowledge, sustainability certification, etc.
• Universities Emerging integration of BIM in teaching and research
• Al companies The beginning of training offers Establishment of the planen bauen 4.0 GmbH
