The project did throw up some health and safety issues, we had to overcome with working at height on the top of a shear drop into the moat of the Redoubt. This was overcome with the use of man safe running lines with ground anchors.
The client was very happy with safe and timed installation date. Feedback from the end client has been very positive and was well received and lead on to further work with the end client.
