Overall, the turnkey setup and efficient project management made it possible to open section by section for a public demo run starting in July 2019. The full extension was already in operation on December 23, 2019 – three months before contractually agreed. The project team also had a focus on safety, achieving a total of 742,000 man hours with zero safety incidents.
