This month marks the 25th anniversary of the September 11th attacks on the twin towers of the World Trade Center in New York City.
For a brief time after the catastrophe that claimed 2,977 innocent lives, public feeling soured on skyscrapers as unsafe and uniquely vulnerable to attack.
More recently, supertall glazed towers have been criticised as unsustainable as temperatures rise to new extremes.
In our latest episode, two prominent and leading proponents of tall have their say.
Structural engineer Kamran Moazami is managing director of WSP’s UK Property and Buildings business, whose credits include 22 Bishopsgate and One Blackfriars.
Building services engineer Nick Offer is head of London building services at WSP. Before that, Offer worked for Arup, where he was project director for building services at the Shard – a project he worked on with Moazami.
In a fascinating discussion including Construction Management editor Will Mann, we probe how 9/11 changed tall-building design, the emerging strategies for building tall in a hotter world, and why, according to Moazami, “tall is the answer” when it comes to effective land use and urban development.
