Messrs. TRUMPF, a technology venture focusing manufacturing and medical technologies, erects a new works restaurant on the premises of their headquarters in Ditzingen near Stuttgart.
The polygonal low building is approximately 10 m high, 60 m long and 45 m wide, and is provided with a continuous façade consisting of a pure mullion construction without transoms made of welded steel T-profiles.
The mullions support the glazing via welded transoms disappearing in the horizontal glazing joint. Vertically the glazing joint is carried out with pressure beads, horizontally with silicone. Fabric sunscreens that can be drawn up from floor embedded shafts are used inside.
The wooden truss roof construction has 32 no. polygonal recesses with varying geometry and is closed by skylights. These 2 % sloping skylights consist of a subconstruction made of steel hollow setions, an accessible glazing and a continuous sheet coating.
Areas: curtain wall 1,200 m2, skylights 260 m2, windows, doors 80 m2.
Glazing curtain wall (with antifall guard): Solarlux neutral 68/34 external: laminated glass 16 mm made of 2 x heat strengthened glass 8 mm, 1.52 mm PVB, 16 mm cavity, internal: toughend safety glass H 12 mm;
(Standard) façade: Solarlux neutral 68/34, external: toughened safety glass H 12 mm, cavity 16 mm, internal: toughened safety glass H 12 mm;

ROYAL ONTARIO MUSEUM (ROM), Toronto, Ontario (Canada)
Architect: Studio Daniel Libeskind with B + H Architects, a Joint Venture, New York
The Royal Ontario Museum ROM is located directly in the centre of the Canadian city Toronto. ROM is famous for its great variety of collections from the history of civilisation of men and for its unique exhibits of prehistoric dinosaur skeletons. The New York Architect, Daniel Libeskind, was instructed with the enlargement of the building. Libeskind adjusted the building, shaped like a crystal, to the existing old building.
The spectacular “Crystal” does not only offer further space for the collections of the museum, but has itself become a unique architectural exhibit of the museum and a salient new landmark of Toronto.
The Crystal consists of five individual crystals combined with each other. Each crystal has 4 to 6 separate areas. The Atrium and the connecting areas form the sixth independent crystal closing the gaps between the old and the new structure. It is remarkable that the new building does not have any straight walls. All areas of the Crystal are sloped in one or two plane surfaces. This results in very unusual cuttings of the individual inclined planes and accordingly in complications during the engineering.
The main structure of the individual crystals is built with rolled steel sections in skeleton construction, whereas the complete structure is stiffened by reinforced concrete slabs in sandwich structure and by the lifting cores. A horizontal curtain wall panel construction (size: approx. 8,500 m2) was elevated onto the subconstruction.
The complete panel/stick construction is made of light profiles. Grid 1200 x 1200 mm was chosen for the heavily loaded areas and grid 1300 x 2000 mm for the standard areas. As tight and water leading level sandwich panels were inserted in the stick construction, which are sealed and fixed with pressure beads.
Finish: natural anodized in E6-C0.

C42 VITRINE MONDIALE DE CITROËN, Paris (France)
Architect: Manuelle Gautrand, Paris
After breaking down the ancient showroom on the Champs Elysees the building gap has been used to erect the new exhibition hall. The external view of the glazed pyramid façade optically reflects the company logo of Citroën.
The curtain wall area comprises approximately 900 m2. The building is 10.5 m wide and approximately 29 m high. Material used for building purposes: approximately 40 tons of steel profiles (V-shaped welding profiles S355), sizes 100/160 mm, wall thicknesses 5 mm and 20 mm.
The glass pyramids have been executed without visible structural steel sections inside and without pressure beads outside in order to obtain the required all-glass crystal look imitated from the Citroën logo. Due to structural reasons a tensioning device has been developed using steel flat 90/10, running blind within the glazing joint. Only a silicone joint is visible on the outside and inside. As prevent fall protection the glass panes are mechanically supported by point fixings on top of the pyramid and on the bottom area of the tension cables. For the removal of the glass panes the tensioning cables can be slid over the top of the pyramid.
Glazing: white glass 12 mm laminated, 24 mm cavity, 12 mm, high performance coating 67/34, cavity partly with Kapipane transparent, Citroën signs with a four-layer red PVB-foil RAL 3020 and an inner laminated glass pane.
Finish: RAL 9001 with 6 % gold particles.
Completion: 2007

Drugstore Publicis in Paris (France)
Architect: Building Inc., Los Angeles, USA
Executive Architect: HDA, Paris
The building of the Publicis drugstore is situated directly on the Champs Elysées, about 150 metres away from the Arc de Triomphe. This building dates back to the sixties, which has been furnished both in the internal area and in the area of the outer façade with a futuristic design.
All the way round the entire building (Champs Elysées, Rue de Preßbourg, Rue Vernet), front-suspended glass sails in various geometric shapes have been attached, total area approx. 710 m2. The basic elements of these glass panes are cylinders that have been cut slanted, cones and rings, etc. The existing glass façade of the building has been retained in its entirety. The new façade panels are fastened using wall fastening brackets to the main columns of the building clad with natural stone.
Glazing: Optiwhite 16 mm laminated glazing from float glass.
Finish: Steel DB704, stainless steel fins, glass bead blasted.

University of Chicago Graduate School of Business, Illinois (USA)
Architect: Rafael Viñoly Architects PLC, New York
Situated in the heart of the University of Chicago Campus the building of the New Graduate School of Business reflects the surrounding architecture - Frank Lloyd Wright's Robie House to the north, Ida Noyes Hall to the south and the Rockefeller Chapel to the west. The imposing columns and soaring arches of the winter garden echo the traditional gothic architecture. The winter garden is a central meeting place for the Graduate School of Business community offering views to the surrounding landscape.
Each column is made of eight circular hollow sections, each 228 mm in diameter and 18 m in height. The arches are 15 m long, curved in three different radii and taper from 228 mm at the spring point to 152 mm at the top of the winter garden.
The winter garden roof and sidewall glazing comprised insulated glazing units with recessed edge sealant to facilitate the Gartner clip system providing a flush outside/inside surface. The skylight glazing is made of insulated glazing units tied back to the skylight steel via pressure caps.
3-layer coating system: zinc-rich primer, epoxy intermediate coat and polyurethane top coat.
Completion: 2005

The Children´s Hospital of Philadelphia, Phase III Facade Replacement, Philadelphia (USA)
Architect: Ballinger, Philadelphia
Situated in Philadelphia's university quarter, the Children's Hospital of Philadelphia ranks among the world's leading paediatric hospitals. As part of a comprehensive development and refurbishment scheme, the main building was upgraded by the addition of a curtain wall with skylight plus a roof over the main entrance.
Sleeve façade:
The sleeve façade is supported by 24 m tall steel lattice columns at 7.3 m centres. The glazing comprises point-fixed panes with edges enclosed by stainless-steel sections. The roof incorporates a steel-section skylight which runs the entire length of the façade and admits additional daylight into the artistically styled façade cavity.
Canopy:
The canopy over the main entrance is constructed from four projecting steel lattice beams tied back to the façade at the top. The canopy panes are supported lengthwise by on-edge laminated glass beams.
Glazing: curtain walling with laminated safety glass comprising 2 x 12 mm toughened glass with 1.52 mm Sentry Glass Plus interlayer; laminated art glass comprising 2 x 6 mm toughened glass with 1.52 mm PVB interlayer (Vanceva Colour); skylight insulating glass units with 6 mm (low-E) toughened glass, 12 mm cavity, laminated safety glass comprising 2 x 6 mm heat-strengthened glass; canopy glass beams in laminated safety glass comprising 4 x 12 mm toughened glass with 1.52 mm PVB interlayer; roof panes in laminated safety glass comprising 2 x 12 mm toughened glass with 1.52 mm Sentry Glass Plus interlayer.
