Structural safety and CPD: what's changing and what do I stand to gain?

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 on conversion and refurbishment work on a listed building that led to structural failures of beams and subsequent difficulties in resolving safety matters between the various agencies involved.

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.
