S-Bahn connection Tunnel Update

The awarded section of the S-BAHN project in Berlin was safely completed in April 2019. On 9/5/19 a visit was conducted as the entire building pit was pumped dry and it is a amazing site to see the incredible large hall construction which was completely dredged and constructed underwater and underneath the exciting infrastructure. Aside from the impressive concrete floor pouring, the very large concrete slab (left in the picture) is as impressive. Both floor and slab were poured underwater underneath the existing infrastructure.
