390 Fabrication issues with imported steelwork truss in Australia
A truss structure was tendered locally (in Australia) but fabricated overseas and imported. The construction, says the reporter, illustrated significant defects and deflected after erection requiring rectification.
433 Failure of pre-cast concrete 'L' shaped retaining wall
A recent incident occurred on a site, where a temporary pre-cast retaining wall failed leading to a pile of clay approximately 3m high spilling through the wall.
The success of CROSS depends on individuals and firms participating by sending reports of their experiences and concerns in confidence to Structural-Safety. There are far more failures or concerns than are reported so there is considerable scope for progress. The names of reporters are never revealed and only the technical aspects that could help structural engineers are published.
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:
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.
