This month we present key elements of a CROSS Safety Alert from December 2020 detailing the failures and lessons learned from the Florida bridge collapse in 2018.

This month we present a report about a permanent works design engineer who noticed that hydro-demolition of the end of a floor supporting beam had taken place out of sequence. This introduced a pattern of bending moments and shear forces that were not considered in the original design.

This month we present a report concerning the partial collapse of a cantilevered stone staircase without warning during a renovation at a stately home built around 1830.
