New Reuss Bridge Gnadenthal, Stetten/Niederwil

Category: Bridges, News
Year of construction: 2015 - 2016
Location: Niederwil, Stetten
Owner: Departement Bau Verkehr und Umwelt Kanton Aargau
Client: Rothpletz Lienhard + Cie AG Aarau
Engineer: Bänziger Partner AG Baden

The existing bridge over the Reuss River between the municipalities of Stetten and Niederwil is being replaced in early 2016 by a new steel composite bridge. The new bridge consists of a rust-coloured box girder made of weathering steel and a deck slab of pale coloured concrete. The 100 meter long structure incorporating a double-curve and a sweeping camber is supported by two Y-shaped concrete pillars anchored in the riverbed.

Bridge over the river Murg, Frauenfeld

Category: Bridges
Year of construction: 2013 - 2014
Location: Frauenfeld
Owner: Stadt Frauenfeld / Tiefbauamt
Engineer: ITK Planungen GmbH Frauenfeld

As
part of the development of the regional bike trails in Frauenfeld, a new bicycle and pedestrian bridge over the Murg River has been constructed. The 40 meter long bridge of welded tubular trusses with a steel substructure to support the orthotopic floor panels including railings was erected by Tuchschmid, the local steel bridge specialist. Many spectators watched the special transport thorough the canton capital and the spectacular installation operation beside the main railway line. With a 500 ton mobile crane, the two 20 meters long and 21-ton bridge
sections were lifted and fixed during a night shift.

Gangway Senevita, Spreitenbach

Category: Bridges
Year of construction: 2013 - 2014
Location: Spreitenbach
Client: S + B Baumanagement AG Olten
Architect: S + B Baumanagement AG Olten
Engineer: WLW-Ingenieure AG Zürich

When the residents of the newly built Senevita Seniors Home in Spreitenbach head off to
the neighbouring shopping center they now use the gangway built by Tuchschmid. The 34 meter long connecting bridge consists of a steel base construction, which is resting on steel supports. The flooring is of ribbed aluminium plates and the roof of corrugated sheet. The trusses are vertically clad with chain link fencing which is pierced with bright green framed openings allowing an unobstructed view of the surroundings.

Silo 6 Sugar Refinery Frauenfeld

Category: Bridges, Special structures
Year of construction: 2013
Location: Frauenfeld
Owner: Zuckerfabriken Aarberg + Frauenfeld
Client: Stutz AG Frauenfeld
Engineer: BHAteam Ingenieure AG Frauenfeld

Frauenfeld Sugar Refinery’s largest silo (Silo 6) was completed just in time for the 2013 sugar processing season. It includes a 51 m high staircase consisting of both interior and exterior stairs and a 54 m long conveyor bridge constructed by Tuchschmid. The conveyor bridge comprises of a lateral support structure, the floor structure as well as supports and openings for filling devices. The bridge is clad with a facade and a continuous hand rail to three sides.
A ring rail was also planned, produced and installed to the inside of the Silo roof. Surface treatments were given particular attention, as the components inside the silos required hygienic coatings. The spectacular installation of the bridge components on the roof of the
silo also attracted many spectators.

Lumino Bridge

Category: Bridges
Year of construction: 2013
Location: Lumino
Owner: Comune di Lumino
Architect: Blue Office Architecture Bellinzona
Engineer: Office for Structural Engineering F-Dole, Pini Swiss Engineers Lugano

In the spring of 2013 the Ticino community of Lumino opened a new, sun-yellow steel bridge for pedestrians and bicycles. A special feature is the load-bearing, round balustrades, which give their arrangement on the bridge a playful, lightweight, yet elegant look. The 16 m long and 2.5 m wide bridge including the special silica sand bridge surface was completely manufactured by Tuchschmid in Frauenfeld which allowed for immediate usage after lifting it
into place.

Paradise Street Pedestrian Footbridge, Liverpool

Category: Bridges, Steel and Glass structures
Year of construction: 2006 - 2007
Location: Liverpool
Owner: PSDA Project Management 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.

New Footbridge Klösterlisteg, Frauenfeld

Category: Bridges
Year of construction: 2010
Location: Frauenfeld
Owner: Stadt Frauenfeld
Engineer: SJB.Kempter.Fitze AG Frauenfeld

The modern, steel trough bridge spanning the Murg River at Schloss Park in Frauenfeld is well integrated into the landscape. The new, 3 m wide, clear-span bridge with a span of 25 m offers functionality and aesthetics. The handrails follow the delicate arched form of the bridge which is constructed of monolithic, spatially curved steel box girders. At night the LED lighting integrated into the handrail shows off the bridge its best.

City bypass Berne, freeway access Wankdorf, bridge T2a

Category: Bridges
Year of construction: 2010
Location: Bern
Owner: Astra Bern
Client: ARGE Brücke T2a c/o Frutiger AG Thun
Engineer: ACS Partner AG Zürich

At
the Wankdorf Junction of the multi-year renovation and expansion project of the Motorway Tangent for the City of Berne, Tuchschmid AG constructed a temporary bridge over the SBB railway lines as a bypass. The sophisticated steel structure made of weathering steel has a length of 110 meters and a carriageway width of 13 m. It consists of four box beams with cross-sections varying between 1.5 m and 1.8 m in height with a constant width of 1 m. The bridge features a radius of 1,600 m. The assembly as well as the extension of the bridge took place in stages, which corresponded to the phases in which the bridge was slid into its final position.

Reinforcement SBB Aarebridges, Uttigen

Category: Bridges
Year of construction: 2009
Location: Uttigen
Owner: SBB Projekt Management Olten
Engineer: TSW - Trachsel Schibli Walder + Partner AG Olten

Structural tests concluded that reinforcement of the beams and traverses of both SBB Railway bridges was unavoidable. The measures included bolting additional cross members with the necessary connections to the existing framework for a length of 66 m and a height of 8 m. 30% of the complex assembly work was carried out during the night when the tracks were clear. Along with this work a new steel pedestrian bridge was installed.

Simme bridge, Wimmis

Category: Bridges
Year of construction: 2001 - 2002
Location: Wimmis
Owner: Tiefbauamt Kanton Bern
Engineer: Marchand + Partner AG Bern

The new bridge at Wimmis connects the Lake of Thun A6 Motorway to the Simmental (Simme Valley). The S-shaped curves of the rock-gray steel structure blend beautifully into the impressive and pristine landscape. The 175 meter-long structure – a continuous welded bridge beam construction on steel stanchions – required millimetre precision in the production even at the cutting stage of the individual pieces. Our erectors welded the voluminous beams for continuous steel bridge in situ high above the foaming Simme River.

Three Roses Bridge in the Northern Urban Motorway, Basle

Category: Bridges
Year of construction: 1999 - 2003
Location: Basel
Owner: Tiefbauamt des Kantons Basel Stadt
Client: ARGE Dreirosenbrücke Basel
Engineer: Bänziger + Baccetta + Partner AG, Cyrill Burger Partner AG, Dauner Ing. Conseils SA, Steib W + K Architekten

The double-decker “Three Roses Bridge” in Basel reflects the art of steel and concrete bridge construction. This delicate structure is characterized by its transparency. Special truss nodes are the key elements of this 265 m long, 15 m wide and 8 m high composite truss bridge. The most difficult challenges to overcome during installation was the barging of the 265 m long bridge segments to the site, turning them 90° into position and then raising them to the proper height. In their final position the segments were then welded together.
