: In depths up to 30 m beneath the centre of San Francisco, the enormous building structure Chinatown Subway Station has been realised.

The oval-shaped underground structure measures 15 m in diameter and is 60 m long.

The high load-bearing capacity of the system components facilitated the safe transfer of large loads while allowing flexible adaptation to accommodate the challenging tunnel cross-section.

In order to keep the supporting structure safely balanced, concreting was carried out alternately on both sides. Vibrators mounted on the formwork ensured uniform distribution of the concrete.

When adapting to match the change in the cross-section, the Telescopic Posts could be quickly adjusted to the correct length in just a few steps.
