The Company
1947 Technical Report «Journey through the Gotthard-Base-Tunnel in
the year 2000» by Eduard Gruner about the visionary idea of a
Gotthard-Base Tunnel from Amsteg to Biasca including a station
in Sedrun with an approx. length of 50 km.
1970 changed to the limited company Gruner AG.
1862 "Ingenieurbüro Dr. H. E. Gruner & Sohn" founded by
Heinrich Gruner with the focus on the Basle watersupply.

The Company
Gruner today:
Leading engineering and consultancy company in the area of structural
and underground engineering, building services engineering, energy
systems, environmental and safety with international focus.
Group of 14 independant companies at 31 locations with 1.000 employees.
Remarkable combination of 150 years tradition as a typical engineering office
with the high standard of a modern, capable and efficient group of companies.

1st V
Verification . . .
select clear and simple examples
mind adequate documented cases
to be done within manageable timeframe
keep up-to-date with new features and capabilities
should be a self-evident, permanent part of the workflow
. . . we don't spend a word on this!
6
2nd V
Validation . . .
select significant and detailed experiments
especially mind comprehensive and detailled documentation
to be done with a manageable effort
keep up-to-date with new approaches and methods
. . . could be as difficult as expensive!
7
3rd V
Visualisation . . .
establish extensive network of interdisciplinary resources
be aware of new methods and technologies in presentation and documentation
focus on easy access through the most common interfaces
stay in close touch with related disciplines
. . . looks that promising to be pushed seriously!

The Consequences
consecutive proof of simulation against experiment, empirical approach and theory
install DoE-approach to predesign fires and smoke tests
get authorization to verify of emergency and evacuation plans, smoke discharge
concepts and statutory requirements for individual safety and protection
most intelligible presentation of results to a wide range of project parties
prepare your presentations under consideration of the parties being involved and with
respect to their specific CFD-knowledge and understanding
use up-to-date presentation techniques like Virtual Reality, 3D-Visualisation and
Augmented Reality
ensure that your presentations show results in a most vivid and realistic way
