A member of a team working on a major bridge reported a close call after the supporting mesh flooring on a new access staging system gave way under his foot. This failure of the flooring mesh could have resulted in a serious incident.  The access staging was being installed as part of a new system which had recently been fabricated and certified by specialist suppliers for maintenance purposes. 

The primary structural components of the system were globally load tested locally prior to their use and found to pass. However preliminary investigations indicate that the mesh flooring system provided differed significantly from that designed, commissioned and certified as having been supplied and this has had a direct bearing on the load bearing capabilities of the system.

As for report 672 (and many others) a generic issue for designers is to be sure that what is built is what they thought they had designed.  A proper quality assurance (QA) scheme should assure a client that what is being provided matches the design intent.
