The upgrade project has advanced current systems, enhancing public safety and reliability of the city’s transport network.
Environmental events such as hurricane Sandy have had devastating effects on New York and its transport infrastructure, highlighting the need for advancement in design and technology. COWI and CHA were contracted to provide expert quality oversight and coordination of new ventilation and fire systems, including advanced smoke detection and communication systems in the tunnels. All upgrades were completed on budget during the pandemic and on-time, without closing the tunnels to traffic.
Steven Kramer, Senior Vice President and Project Director for the project at COWI said: “This project was very close to home for our engineers, most of us have used these tunnels and know how vital they are to the ecosystem of New York. Working on such a deep-rooted part of our transport network can be challenging but our proactivity and collaboration with construction partners provided a design-build model that offered significant cost and schedule reductions.”
