Donges SteelTec builds new Rhine bridge

Bridge construction division is pleased with major contract for the replacement construction of the Pfaffendorfer Bridge in Koblenz

Donges SteelTec, as part of the ARGE Pfaffendorfer Brücke consortium, has been awarded the contract for the replacement construction of the Pfaffendorfer Bridge in Koblenz.

As an important link across the Rhine, the existing bridge must be completely replaced by a new one. For this purpose, the 311 m long steel composite bridge, which is broken up in the area of the pier coves, will first be built in the lateral position next to the existing bridge and, after the demolition of the existing bridge, will be moved transversely into the final position.

Donges SteelTec is taking over the technical responsibility for the entire structure by preparing the structural analysis of the river bridge, the assembly planning and the execution and workshop drawings within the consortium. Around 5,500 tonnes of steel structure will be manufactured and corrosion-protected in the halls of Donges SteelTec GmbH in Darmstadt. Afterwards, the steel elements, weighing up to 450 tonnes, will be successively transported by ship via a pre-assembly site on the Rhine to the construction site, where they will be assembled above the Rhine by means of floating cranes.

The work for the new Rhine bridge will be carried out between 2023 and 2027

Major order from Salzgitter Flachstahl GmbH

Another milestone in the company history of Donges SteelTec GmbH.

 

Structural engineering division receives major order from Salzgitter Flachstahl GmbH for the construction of a new 63-metre-high production hall. The contract includes the delivery and erection of the primary as well as the secondary steel structure including the building envelope with doors and gates. Drainage, lightning protection and SHEVS are also part of the contract.

Donges SteelTec is preparing the shop drawings and the erection planning. It is planned to erect the 8500 tonne steel structure using conventional lifting assembly. Erection is scheduled to start in mid-2023.

The 183 m long, 46 m wide and 63 m high hall will be equipped over its entire length with a crane runway for two bridge cranes with a load capacity of 500 tonnes each. Due to the partially large distances between the columns, the crane runway girders are designed as open welded profiles with an overall height of 4500 mm.

The entire project is being realised as a joint venture with the company GP Hoch- und Ingenieurbau GmbH, Hanover.

“We are very proud to have been awarded the contract for this forward-looking project. In this new hall construction, we can perfectly combine our know-how and experience from structural steel engineering as well as bridge construction,” says Dr Wolf Cornelius, Managing Director of Donges SteelTec GmbH.
