PROJECT GOALS
The Dortmund-based world market leader
and pump manufacturer WILO SE is
converting its headquarters into the WILO
campus.
As part of this development, WILO SE
plans to complete the master plan for the
efficient consolidation of administrative
and production areas on the traditional
WiloPark-Allee
(formerly
Nortkirchenstrasse). The aim is to secure
existing jobs in the region and to create
the basis for additional modern jobs in
Dortmund. The further development and
expansion of the company's premises in
Dortmund is thus a clear commitment to
the Ruhr region.
WILOPARK
To be future-oriented, flexible and adaptable and
WILO GROUP AND
SUSTAINABILITY
The concept aims to connect the two
parts of the area as closely as possible
and the function-related
heterogeneous typologies and
dimensions on both sides of the Wilo-
Park-Allee. The subject of this service
description is the design and
construction of a new turnkey facility
for use as an office and administrative
building of the development. Directly
related, is the new construction of the
laboratory building EE-LAB, which is
being built.
The goal of the project is to achieve a
functional and economical construction,
taking into account the requirements of
WILO SE to acquire. By this, its urban
development, architectural and
functional qualities, as well as energy
and ecological quality, attach great
importance to ecological sustainability.
to be able to provide space for a broad product
portfolio and production technologies of the
future, a total area of 20 hectares was required for
the new plant structure. For this reason, Wilo
decided not to simply expand and extend the
traditional location.

GREEN CERTIFICATION
A S Y S T E M A T I C A P P R O A C H T O S U S T A I N A B I L I T Y
In March 2021 Wilo achieved climate neutrality
and received LEED Gold and DGNB Gold
certification. The Wilo Group celebrated no
fewer than three sustainability milestones
during this time: The successful completion of
TÜV certification as a “climate-neutral
company in Dortmund” as well as the
Leadership in Energy and Environmental
Design (LEED) Gold certification award from
the U.S. Green Building Council (USGBC) and
Gold certification from the German
Sustainable Building Council (DGNB), both for
the “Pioneer Cube” administrative building.
The goal for this project is to be certified by
DGBN Mix 18 (common certificate for the
office building and EE-lab) and LEED v4 Gold
(for each building separately).
LEED
LEED (Leadership in Energy and
Environmental Design) is the most
widely used green building rating
system in the world. Available for
virtually all building types, LEED
provides a framework for healthy,
efficient, and cost-saving green
buildings. LEED certification is a
globally recognized symbol of
sustainability achievement and
leadership.
DGNB
The DGNB certification system is
considered the most advanced
system of its kind in the world and
is internationally recognized as the
global benchmark for
sustainability.
The DGNB System is based on
three fundamental factors:
Life cycle assessment
Holistic approach
Emphasis on performance

OUR ROLE ON THE
PROJECT
WHAT WE DO
We work as subcontractors for the
General constructor – Hellmich group –
connect all subcontractors' solutions in
one BIM model, with the support of
consultants and experts involved in the
project to come to the desired result.
Modelling architectural part
Modelling concrete structures
Coordination of electrical and mechanical models
Coordination and clash detection between disciplines
OUR APPROACH
All Ržišnik Perc solutions are designed with the customers’ success in mind. We strive to build
long lasting and mutually beneficial relationships rather than focus on short-term business.
Integrated design and construction management relies on the interdisciplinary and collaborative
efforts of all parties involved on every stage of design, construction and operation.

ARCHITECTURAL MODELLING
T H E M O S T D E M A N D I N G P A R T O F T H E P R O J E C T
The architectural model is the basis for all
other disciplines, that is why it is the most
demanding and responsible part of work.
If something goes wrong in the
architectural model, the cost of changes is
too high, as it affects every other project
party.
The very first challenge is that another
company did the initial project. From the
time of submission of the conceptual
design, a lot of changes happened, that
have to be implemented in a new design.
One of the significant modifications was a
complete change of the structural schema
- from the precast concrete system to a
monolithic type. High demand on the
market for prefabricated concrete panels
did not allow the construction to be
finished on time.
The architectural model is in Revit based
on the template and according to the
investor standard. The model of LOD 350
will be delivered at the end of the detailed
design phase.

Our role is to provide formwork and
reinforcement shop drawings first to the
proofer for verification and then directly
to the construction site.
The main challenge is the high speed of
changes (change in the construction
type, architectural plans or MEP systems).
DESIGNING CONCRETE
STRUCTURES
One of the peculiarities of this project is
the high groundwater level. In
collaboration with other structural teams
taking part in the project, our structural
engineers implemented a solution for a
waterproofed connection of the existing
building concrete structure to the new.
The solution for the construction of a
waterproof concrete foundation slab was
implemented in the project. The problem
solved there was a high heat release
during the hardening process that could
cause concrete cracking in large areas.
Also, based on the preliminary design and
calculations provided by Hellmich, our
structural team developed the Vierendeel
beam for eight meters-long cantilever.
The main challenge in this project is
the high speed of changes
An additional level of complexity was
added by the fact that construction
started before the design phase was
finished. That is why, all the changes that
are happening, are important to
implement and communicate with other
participants as soon as possible.
Apart from the fast velocity of work
demanded, we have structural puzzles to
solve in this project.

MEP MODEL COORDINATION
C R U C I A L P O I N T S O F M E P I N T E G R A T I O N
Integrating MEP model with the structural and
architectural solutions is a sensitive task. Some of
the crucial points that need consideration for
MEP BIM integration include – space allocation
during the design phase, fulfilling spatial
requirements for MEP systems and individual
equipment etc. Even though we are not the main
MEP systems designer, we play a substantial role
in coordinating them all in one model.
We collect drawings and models in different
formats from 4 design companies. The goal is to
coordinate them between each other and
architectural and structural parts, as well as
provide an optimal solution for the building. That
is all while constant changes in design are
happening and construction of the building is
ongoing.

COORDINATION AND
CLASH DETECTION
Project coordination and clash detection are
critical parts of the integrated BIM design
process. At this point, all the inconsistencies and
problems are coming out. It is a necessary
process because several models are integrated
into one BIM model. In the case of the current
project, the high complexity of the systems and
a big number of participants could cause
multiple bigger and smaller mistakes,
discovered only during the construction.
More than 20 different design companies are
involved in this project. They all use different
software and must be coordinated in the same
model to avoid all possible conflicts during
construction. We coordinate in Navisworks and
communicate weekly with all project teams.
BENEFITS OF CLASH DETECTION
Accurate engineering design
documentation
Fewer iterations during the construction
phase
Better coordination and collaboration
between teams
A streamlined and integrated approach
