36: Big Dig

Listen Later
A series of concrete ceiling tiles in a tunnel portal collapsed on a moving car killing the passenger in downtown Boston in 2006. The selection of the epoxy used in the ceiling tile anchors was unusual and a failure to heed the warning signs were at odds on a huge project under pressure to deliver when already twice over time and five times over budget.
With John Chidgey.
