437 Mobile message board in strong wind

A mobile variable message sign was set up on a hard standing away from the hard shoulder on a motorway and when the wind caught the sign it acted as a sail and moved across the lanes.

CIRIA event on movement in buildings - January 2015

CIRIA have updated their seminal guidance about the effects of 'movements' in buildings. Quite a few of the problems reported to them include stressing or loss of support due to thermal, shrinkage and other movement effects. CIRIA are running a CPD event on 27 January 2015. Click on 'View Report' for web link.

Current matters
under consideration

  • Objects/components falling from buildings
  • Weather damage to buildings
  • Structures at the end of their design life
  • High strength steels

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



January 2015 CROSS Newsletter No 37 published

December 2014: Topic paper Elliot Mall Inquiry published

The success of CROSS depends 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/ submit-report/.



Structural-Safety combines CROSS (Confidential Reporting on Structural-Safety) and SCOSS (Standing Committee on Structural Safety) to work 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
  • helps to influence changes to improve structural safety.

CROSS aims to improve structural safety and reduce failures by using confidential reports to highlight lessons that have been learnt, to generate feedback and to influence change. SCOSS is the independent body established in 1976 to maintain a continuing review of building and civil engineering matters affecting the safety of structures. SCOSS aims to identify in advance those trends and developments which might contribute to an increasing risk to structural safety.
