How safe was the River Rea pipe lifting operation?

摘要

I'm sure I won't be the only civil engineer with a concern for site safety to be disturbed by the dangers to which the construction worker is exposed as seen in the photograph (see above) of the use of Weholite at the River Rea project (NCE last week).rnIt's clear that the man attempting to guide the very large load from his precarious footing on the top of the curved and gravel-strewn top surface of the 3.5m diameter plastic pipe has no safety equipment or other means of preventing a potentially serious fall.
