Industrial construction

Strict requirements for the best production facilities

Customer: Kleemann Immobilien GmbH, Göppingen
Construction time: November 2008 - September 2009

Project description:
Creation of a production or with an adjoining social area, with an overall floor area of 25,000 square metres in Göppingen for Kleemann GmbH.

Special features:
Advanced engineering and structural analysis on behalf of LEONHARD WEISS. Costly production of pits and machine foundations with very high flatness tolerance requirements. Planning and implementation of the Water Act requirements. Extensive construction with finished parts and steel. Execution within a very tight schedule.

 

 

 

Building a confined space

Customer: Hochtief Projektentwicklung GmbH, München
Main shell construction time: December 2007 - August 2008
Extended shell: September 2008 - April 2009

Project description:
The "Altezza" office building with casino and underground car park was built at in München-Westend at Barthstrasse 4 / the corner of Landsberger Strasse. The building is designed for use as offices and commerce. The 2-storey underground car park with 261 parking spaces, storage areas and functional areas extends under the three vertical building sections.

Vertical building sections: G, 1 - 4. The upper floors and top floor are made up of an L-shaped structure 1 in the north, a rectangular frame 3 with quadrangle in the south and a connecting central rectangular building 2.

Special features:
Underground execution as "waterproof concrete". Access via Barthstrasse only (very cramped, hungry pumps, mostly only with piping and rotary distributor).
Facade formwork:
- 800 precast facade parts
- 22,000 cubic metres of concrete (2,750 mixers)
- 3,200 t of reinforcing steel
- 68,000 square metres of formwork

 

 

 

Architecture for the most demanding requirements

Customer: Linde AG, Geschäftsbereich Linde Engineering
Construction time: November 2006 - May 2007

Project description:
The building has an irregular shape and an air space that runs through all floors. Its floor plan is approximately 60 m x 85 m. A complex, three-dimensional structural system with large spans and numerous strain relief systems emerged as a result of the staggered ceiling edges, staggered projections of several upper floors and inclined and eccentric cores.

Special features:
- Inclined stairways
- A variety of inclined walls and ceilings,
- Canteen to seat 700
- Meeting room to seat 160
- 6. Upper floor VIP Lounge

 

 

 

A modern exhibition centre with spacious exhibition areas

Customer: Projektgesellschaft Neue Messe, Stuttgart
Construction time: September 2004 - June 2006

In September 2004, LEONHARD WEISS and consortium partners, Bögl M., F. Kirchhoff and K. Fischer were instructed to execute the most complex project in Baden-Württemberg, with extensive road and engineering works and prestigious buildings.

On 19/10/2007, the official inauguration of the future exhibition site took place with the participation of the then Federal President, Horst Köhler, Secretary of State Dr. Horst Mehrländer and Lord Mayor Dr. Wolfgang Schuster, as well as the manager of the consortium partners and other representatives from politics, industry and the press.

 

 

 

The project took off despite poor site subsoil

Customer: Knell Nord Entwicklungsgesellschaft mbH & Co. KG, Darmstadt
Construction time: September 2008 - March 2009

New office and administration building with 7 floors above ground level and a basement (for storage, technical and social areas). The building volume is 60,000 cubic metres with a surface area of 15,000 square metres. The layout of the proposed building is in the shape of the star with three wings and the dimensions of each wing is approximately 15 to 32 metres. The floor heights are approximately 4 m on the ground floor and 3.20 m on the upper floors. The total building height is 25.50 m, excluding technical equipment spaces.

Because of the soil conditions, the pile foundation method was chosen for the building. The building was built as a reinforced concrete frame construction and consists of flat slabs, columns, walls, reinforcing cores and load-bearing parapets. From the ground floor ceiling upwards, mixtures of concrete were selected to aid cooling.
- Concrete: 7,800 cubic metres
- Reinforcing steel: 1,100 t
- Concrete core activation: 8,500 square metres

 

 

 

An engineering masterpiece

Customer: EMBL Heidelberg, European Molecular Biology Laboratory
Construction time: 18 months, 2007 - 2008

Special features:
As with DNA, buildings consider a double helix to be a basic geometrical structure. In the same way as two strands of DNA that are spirally wound around each other, in the ATC, two building strands are wound around each other to form a double helix. Similar to DNA strands in the form of "spokes", the so-called base pairs are linked to each other to connect the glass bridges of the ATC building strands.

The new building consists of two building parts, which are connected to each other above two basement floors:

The Casino has four floors and is used as a canteen, kitchen, teaching laboratories and seminar rooms.
The Helix consists of "six upper floors" with levels in the shape of a double helix strand, as well as two basement floors, and is used as a conference, training and exhibition building. The 450-seat auditorium is in the basement. The auditorium ceiling is intercepted by two lens-shaped concrete pillars. The "upper floors" consist of a total of 66 levels, which are connected to each other by three steps. Adjacent to these, a steel inner ramp and an outdoor concrete ramp connect the segments to each other. The top of the building consists of an exposed concrete ring on supports.

 

 

 

Major challenge for planners and executors

Customer: Wissenschafts- u. Kongresszentrum Darmstadt GmbH & Co. KG, Darmstadt
Construction time: 2005 - 2007

Special features:
Conference centre with conference hall (1,650 seats). 20 conference/seminar rooms, restaurants and the Cybernarium are located on the three upper floors. Three basement levels consisting of a service floor square and 2 parking levels with 420 parking spaces have a floor area of 8,000 square metres.

On the upper floors, the inclined columns/pylons and wall elements were constructed using SB4 facing concrete. The formwork plans were all converted from 2D to 3D by LEONHARD WEISS.
- BRI: 120,000 cubic metres
- Gross floor area: 28,000 square metres
