Project Description:
As part of the new construction of an ÖBB bridge over state road L270 and the Salzach river in Unterlend, two new bridge superstructures were erected for Track 1 and Track 2.

The bridge has a span of 58.0 meters and a total weight of 487 metric tons. In addition to the new construction, the project also included the demolition and professional disposal of the existing superstructures.

Scope of Services:
Engineering, fabrication, corrosion protection, and assembly of the new construction, including demolition and disposal of the existing superstructures

Client:
Steiner Bau GmbH

In the summer of 2019, the existing Stössingbach Bridge was renovated. The project included the dismantling of the old bridge structure, as well as the fabrication and assembly of a new bridge superstructure.
Special attention was paid to rapid implementation while traffic was ongoing and under confined space conditions, which required a high degree of logistics and precision.

Scope of Services:
Fabrication and assembly of the bridge superstructure

Client:
Porr Bau GmbH

Execution Period:
June – September 2019

For an infrastructure project by Verbund AG, two composite steel bridges with a span of 21.2 meters and a bridge width of 6.21 meters were manufactured and installed. The total weight of the structure is 85 metric tons.

The project encompassed all services from planning and manufacturing to corrosion protection and professional on-site installation.

Scope of Services:
Engineering, Manufacturing, Corrosion Protection, and Installation

Steiner Bau GmbH
End Customer: Verbund AG

In the fall of 2017, we were awarded the contract to manufacture a new bridge near Mayereinöd in Salzburg as part of the flood protection measures along the Salzach river.

The new structure was designed as a composite bridge. Precast TT slabs with external reinforcement were used in the transverse direction—a solution that allowed for both high slenderness and a short construction period. All steel components and the reinforcement were manufactured in our plant and provided with the initial corrosion protection.

The main girders, each 25 meters long, were transported to the construction site and welded there. A particular highlight was the lifting of the 50-meter-long girders using a 600-metric-ton crawler crane—an event that also attracted numerous spectators from the surrounding area.

Scope of work:
Manufacturing, delivery, assembly

Steiner Bau GmbH

Execution period:
October 2017 – June 2018

A new pedestrian and bicycle bridge was constructed over the Traun river in the municipality of Ebensee.
The bridge has a span of 72.0 meters and was built to execution class EXC3 according to EN 1090-2.

Scope of Services:
Delivery and installation of the structural steelwork, including corrosion protection and surfacing work

Client:
Marktgemeinde Ebensee
4802 Ebensee

Execution Period:
Spring 2018

In October 2017, we were awarded the contract for the new construction of the Eichstraßenbrücke in the center of Salzburg. The 70-meter-long arch bridge was manufactured at our plant in St. Paul, transported to Salzburg by special transport, and assembled considering the inner-city conditions. The pedestrian walkway was directly attached to the main supporting structure.

The shifting operations took place during night hours to minimize disruption to safety and traffic flow.

Key Data: Weight 450 metric tons of steel

Client:
City of Salzburg

Execution Period:
April – August 2018

In spring 2017, we were commissioned with the fabrication and assembly of the structural steelwork for a movable bridge over the Salzach river in Mittersill, municipality of Zell am See (Salzburg).

The lift bridge consists of six bridge subassemblies with individual weights between 38 and 48 metric tons, as well as four steel pylons, each weighing approximately nine metric tons. In case of flooding, the bridge can be raised by 1.80 meters.

Scope of Services:
Fabrication and assembly of the structural steelwork
Key data: approx. 250 metric tons of structural steelwork

Execution Period:
Spring 2017

For the expansion of the Ötztal Cycle Path, the Ferdinand Cycle Bridge was constructed over the Ötztaler Ache in Längenfeld. The bridge has a span of 65.7 meters and was manufactured in execution class EXC3 according to EN 1090-2.

Due to the confined space conditions on-site, the 72-metric-ton structural steelwork was fully pre-assembled at an assembly site. Transport to the lifting point was carried out using special module transporters. The final positioning was performed with two mobile cranes.

Scope of Services:
Delivery and assembly of the structural steelwork, including corrosion protection and bridge equipment

Client:
PORR Bau GmbH, Civil Engineering / Tyrol Branch

Execution Period:
Summer 2018
