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.

Location:

Brooklyn, Wondabyne, NSW

Budget:

$1m – $2m

Duration:

12 weeks

Completed:

2009

The scope of works included

  • Sandstone was delivered using barges to ferry trucks
    from Brooklyn to Long Island and then loaded onto
    barges which were taken to Wondabyne.
  • The Wondabyne seawall was reconstructed using a
    drilling rig to install stainless steel rock bolts and then
    shotcreted using barges carrying a concrete truck,
    shotcrete pump, compressor and personnel.

The Results

This project overcame huge logistic issues but most
importantly was performed in a way to ensure no impact
on the environment and secured the protection of the
endangered sea grass and mangroves.
