Engineer: Basler + Hofmann AG Zürich

Near the Zurich-Altstetten railway station, a complex including three residential towers is
was built on the former site of the Vulcano Automobile + Motorboot Factory. The base buildings which house hotel, catering and retail form a conspicuous contrast to the narrow rising residential towers. The base buildings are connected on three sides with the two
glass roofs creating a semi-enclosed urban space separated from the residential space
above. This allows for a wide range of uses and at the same time performs the function
of a sound barrier. In total, the two steel-glass structures cover an area of 2,110 m2 and require 175 tons of steel.

Pavilion Chilbiplatz (New Town Square) Egg

Category: News, Steel and Glass structures
Year of construction: 2017
Location: Egg

Architect: Hager Partner AG Zürich
Engineer: Tuchschmid AG Frauenfeld

With the redesign of the Chilbliplatz (new town square), the municipality of Egg has created a lively space for its residents. The main feature of the square is the cantilevered, translucent pavilion roof over the exit of the underground car park, which can be illuminated in various colors thanks to the integrated LED lighting. The main girders made of steel sheet are located eccentrically above the concrete structure and cantilever out free of support. They extend parallel to each other from the central integrated drainage channel over the entire length, tapering off at the ends. The right-angled cross members give the framework its checkerboard pattern. The roof is clad with a mix of aluminum panels and laminated safety glass. A smaller pavilion, consisting of four columns and a similar roof construction integrates vertical glazing as a windbreak.

For the Pritzker House, a separate building complex of the 7132 Hotel in Vals, Tuchschmid created 22 unusually shaped shower cubicles in  a white and yellow design. An intensive planning phase was required by Tuchschmid before the cubicles could be installed. The showers are composed of three spherical curved printed glass panels and an aluminum construction for the shower floor. The LED-lit shower cubicles are a central element of the rooms designed by the world-famous architect Thom Mayne.

Opera Terrace, Covent Garden, London

Category: Stainless Steel Construction, Steel and Glass structures
Year of construction: 2015 - 2016
Location: London
Owner: Capco London
Client: Ellmer London
Architect: Eric Parry Architects London
Engineer: Eckersley O'Callaghan London

The entire steel and glass structure over the first floor terrace of Covent Garden is being replaced. Trusses of a special duplex stainless steel are being inserted at grid intervals of
2.75 metres over the total width of the facade and to a depth of 7.50 metres. Where the roof joins the building, it will largely be covered with closed panels, but where it meets the terrace it will be fully glazed with exterior shading. Each 2,75 metre wide segment of the vertical glazing is split into three openable sections. The extension is connected to the existing structure, which has a variable height, hence the dimensions of each segment are individually adjusted, the trusses are slightly twisted and the glazing above the trusses has a distinctive spherical curvature. A 1:1 mock-up of one of the segments is currently on the grounds of Tuchschmid AG factory in Frauenfeld, and all the parties involved in the project have met regularly to examine the samples and refine the individual and highly ambitious solutions.

Site managem.: innoraum Kräher Jenni + Partner AG Frauenfeld

Currently on Langfeldstrasse in Frauenfeld the multi-storey commercial Business House Multiplex 1 is being built. The owner has given the forward-looking economic and ecological composite construction practice priority. This allows the master builder, in collaboration with the steel fabricators Tuchschmid, rapid assembly and construction. Thanks to the steel composite beams, which are placed on Tuchschmid-ATLANT® columns, less load is transferred to the foundations due to the light weight hollow ceiling elements being used instead of conventional poured concrete floors. Overall, more than 500 tons of steel was installed on building object.

Owner: Stadt Winterthur / Tiefbauamt
Architect: Stutz + Bolt + Partner AG Winterthur
Engineer: Dr. Schwartz Consulting AG Zug

The new roof of the bus station in Winterthur fits perfectly into Tuchschmid’s reference list of complex bus stations. The geometry of the “mushroom” creates the most complicated of elements and with its cantilevers, the largest being 34 m, is also a structural masterpiece.
Leading from the Mobility Centre at the foot of the roof, steel beams branch out radially in all directions, forming a hat-shaped, asymmetric structure with an overall roof area of 1’500 m2. The steel and glass structure also includes a perforated metal soffit. The extremely tight time window, from planning through to installation and commissioning within a year, is in addition to project’s geometry and location is a special challenge.

GMZ Herdern, Zurich

Category: Windows and facades, Steel and Glass structures
Year of construction: 2009
Location: Zürich
Owner: Genossenschaft Migros Zürich (GMZ) Zürich
Architect: Oppliger Architekten Zürich

The revival of the industrial district in Zurich-West has resulted in new traffic situations which led the Migros Cooperative Zurich to redesign their entrance area. The result was a free-standing glass cube which, via stairs, elevators and an attractive 40 m long footbridge regulates access to the business tower and reception. There, a new 35 m x 10 m steel platform was constructed to serve as a hub between administration, operation and restaurant and retail space. The energy requirements for this new building are covered by the solar facade on the cube. At night the façade exudes a special glow, as the solar panels provide power for the installed LED lights. A feast for the eyes is the sheet metal soffit to the footbridge which emphasizes the large structure down to the millimeter.

Paradise Street Pedestrian Footbridge, Liverpool

Architect: Wilkinson Eyre Architects London
Award: Prix Acier 2009 Anerkennungspreis, RIBA Award 2009

The unique shape of the new 60-meter-long pedestrian bridge that floats eight feet above Paradise Street in Liverpool draws attention to itself. The closed, fully welded steel bridge connects two differently oriented start and end points. 43 angle-shaped frames made of solid stainless steel serves as the supporting structure for the outer glass façade and the inner acrylic panels complete with integrated LED lighting. The bridge was transported from Frauenfeld to Liverpool in three sections, welded together on site and raised in various night maneuvers, partly under full traffic conditions. With its distinctive angular geometry of the steel and glass the structure was not only a technically complex challenge solved, it also created a distinctive landmark to the area. The interaction of design, fabrication and installation, all from one source, proved to be recipe to success for this very complex bridge.

The space frame construction with a length of 240 m and a width of 50 m is supported on the west side with 24 inward inclining and up to 17 m long columns, which also serve as a horizontal stabilizer. The east side is supported on 27 bearings plates which allow for + / – 200 mm horizontal movement. The white roof construction, which slopes in all directions, seems to float above your head. With 14,000 different steel parts, of which 3,000 were different shaped steel pipes, this project was one of the most demanding projects in Tuchschmid’s history.

When the members of the Hurlingham Club in London meet in the new east wing of the clubhouse, it is done under the glass dome and vault built by Tuchschmid. The steel and
glass structure serves as a showpiece for the club and transforms during the day into
a light-filled meeting place with southern charm. The dome, with its faceted glass panels, resembles a spider web. This faceted glass system is continued on the vaulted roof of seventeen equally spaced panels and an end panel.

Top performance on this project! The completion of this ambitious, three-storey project with 36,000 m2 of modern exhibition space in a construction time of less than ten months is a near record-breaking performance. The 11,000 tons of steel for the steel-concrete composite construction was, thanks to a high degree of prefabrication and to the meticulous planning and implementation of an elaborate assembly concept, all fitted in less than three months. The exhibition hall is 200 m long, 90 m wide and 24 m in height.
