Black Hawk aids weir upgrade

“It took just a few hours on Thursday morning for the Sikorsky Black Hawk helicopter to replace the walkway on the downstream face of the weir,” a WaterNSW spokesperson said.

“A comprehensive analysis of the project indicated that a crane of sufficient capacity to undertake the work could not access the worksite without being disassembled and then reassembled on site, as well as building a temporary crane pad and removing nearby gardens.

“This costly and time-consuming exercise would then need to be repeated to get the crane to the other side of the river to complete the work, making a helicopter the most cost-effective solution.

“Work to install handrails on the new walkway will continue over the next few weeks to complete the safety upgrade.”
