Brooklyn Foreshore Restoration - Marine Seawall Construction
The works involved the remediation of 3 seawalls at various locations on the Hawkesbury river. The foreshore restoration could not be performed from land. To overcome this hurdle all works were performed from barges with further logistic issues including the transport of sandstone to a remote part of the river surrounded by National parks which had no vehicular access.
