619 Unrestrained stone cladding

A leisure complex completed in the early 2000s has a steel frame with infill panels of block covered with thin stone cladding and a person was injured when a large piece of cladding fell. Local investigation revealed that there were insufficient vertical or horizontal dowels to restrain the cladding.

615 Inadequate bolted connections supporting stairs

When precast concrete stairs are installed, the landings are normally supported using either proprietary telescopic connectors (AKA ‘invisible connections’), or by means of an RSA bolted to the wall. When an RSA is used, the wall is drilled to fix the bolts, whether they be expanding fixings or chemical fixings, and frequently the drilling may hit reinforcement.

Current matters
under consideration


  • Quality of construction
  • Quality of supervision on site
  • Use of Resident Engineers
  • Fire stopping
  • Gas explosions and robustness
  • Weather damage to buildings

Reports on these subjects are sought, as well as on any other concerns.

We depend on individuals and firms participating by sending reports of their experiences and concerns in confidence to Structural-Safety. The names of reporters are never revealed and only the technical aspects that could help structural engineers are published. 

If you have an experience that could be useful to others please contribute by sending a report to www.structural-safety.org/confidential-reporting/.


Structural-Safety works with the professions, industry and government on safety matters concerned with the design, construction and use of building and civil engineering structures. It:

  • collects confidential data on the concerns of structural and civil engineers and others
  • provides comments in relation to these concerns
  • maintains a data base of reports and publications
  • collects data from public sources on failures, collapses and relevant incidents
  • considers whether unacceptable risk exists, or might arise in the future
  • promotes a positive attitude to learning from experience
  • influences change to improve structural safety
  • collects data on weather related damage to structures.

Weather damage reports

Severe weather events have caused extensive damage and disruption to infrastructure and buildings with serious consequences for many. Creating a record of damage to buildings and structures has the support of DCLG and other government agencies in the UK to help formulate long term strategies for the Building Regulations. The CROSS system will be used for collecting and processing information and has been adapted to gather the data needed. More information here.

It is recognised that climate change is having effects which may manifest themselves in weather events that result in damage. This study is not concerned with the reasons for climate change but only whether the consequences might lead to changes in regulations and practices.

We are therefore interested in damage caused to buildings and building related infrastructure by weather events. These can be sudden actions such as tornadoes or lightning strikes, or longer term events such as floods. The aim is to gather information that can be used to assess the capability of our buildings to withstand the weather patterns that may be becoming more common. Reports can be made here.
