Mott MacDonald’s Post

In 1964, John Bartlett of Mott, Hay & Anderson pioneered a visionary idea that led to the invention of a new methodology that changed #tunnelling history forever. 🚇 Hear the full story from John Bartlett’s family and our specialists in this #heritage podcast episode with Engineering Matters: https://mottm.ac/3DoWZWn The bentonite tunnelling shield transformed the way tunnels are excavated and contributed to a subsequent rise in safer, more cost-effective designs in challenging ground conditions worldwide. We discuss how this innovation paved the way for a new generation of metros and subaqueous crossings that would not have been possible without pressurised face machines, such as Denmark’s Storebaelt Tunnel and the East Side Access project in New York. Our guests include: - Mike Bartlett, son of engineer John Bartlett - Michael Savill, global practice leader for tunnels - Andy Thompson, head of tunnel design for the US eastern region - Sam Lo Grasso, principal structural engineer for tunnels - Emily Farmer MICE, tunnelling engineer #ThenNowTomorrow #DeliveringExcellence
