Site-failure examples show why the anchor and bracket need to be considered as one support assembly. For M&E pipework, ductwork and cable containment, use each case to ask whether selection matched the substrate and load, and whether installers followed the product instructions.
The CFA (Construction Fixings Association) has published case studies of anchor failures. For each case, check what the source records about the product, substrate, load and installation method.
In the UK, the CFA (Construction Fixings Association) have written a few case studies highlighting past anchor failures.
