Russky Island Bridge – Formwork & Shoring Systems

Project

Construction of Russky Island Bridge, Russia

Scope

Develop a safe formwork and shoring solution for one of the world’s longest and tallest cable-stayed bridges

Challenge

The sloping geometry of the bridge's pylons

Performance

With its span of 1,104 meters, the 3,100-meter-long Russky Island Bridge is not only one of the world’s longest cable-stayed bridges, but also one of the tallest. Crossing the Eastern Bosporus strait, the bridge links the Siberian port of Vladivostok with Russky Island.

A quick and safe ascent was the overriding principle during the construction of the bridge’s pylons, each just over 320 meters tall. The bridge was built with Hünnebeck’s modular self-climbing formwork (SCF). Fully enclosed with a temporary roof, the formwork defied extreme weather conditions. The enclosure ensured risk-free operations at extreme heights where the wind forces can be exceptional and also permitted the heating of the work chamber to allow the concrete to set and be patched — even at external temperatures of minus 40 degrees Celsius.

With the help of Hünnebeck’s formwork solution, the Russian construction company USK MOST completed the ambitious project in the record time of only 43 months.
