West Metro, Espoo and Helsinki

The construction of the West Metro, connecting Helsinki’s Ruoholahti to Matinkylä, in Espoo, involved designing eight separate and challenging station entities and 33 kilometres of train tunnel, including 15 complexes comprising escape routes, pressure-balancing ducts, and technical premises. Other noteworthy tunnel structures include 55 connecting tunnels, large-scale pump systems, a water reservoir for fires, track switch points, and maintenance tunnels and tracks. The project was granted an honourable mention in the Tekla BIM Awards in 2016.
