681 Polyethylene core cladding panels used on residential high rise building

A reporter is writing as a precautionary measure following the Grenfell Tower Fire to say that a similar type of rainscreen panel, ie a polyethylene core with metal skin, was used at a residential tower block which they visited in 2011. It is believed that this block is privately owned so would not necessarily be picked up in a review of buildings owned by local authorities and housing associations.

664 Steel canopy collapse during building completion works

During the construction of a major new school facility, a 57 metre single span structural steel truss failed, resulting in the catastrophic collapse of a steel framed canopy supported by the truss. At the time of failure five workers were on the top of the canopy, some 15 m above ground level. All received significant injuries but survived. The immediate cause of the failure was associated with the fracture of a number of sub-size fillet welds joining paired load bearing tie bars at nodal points.

Confidential Reporting

Confidential reporting was developed as ASRS (Aviation Safety Reporting System) by NASA for the Federal Aviation Authority in the USA. This has been operating for over 30 years and as a result of its success similar schemes have been developed in a number of other countries. In the UK this is CHIRP the Confidential Reporting Programme for Aviation and Maritime.

CROSS is the first confidential reporting scheme to deal with structures.
