Green Island Groyne

Project Description / Overview:

CivilPlus were engaged to construct a Seawall, 60m long to reduce sand migration on the island. This involved the design and installation of 13 precast piles in a very sensitive environmental location. All plant, equipment and materials were barged onto the site, the barge was taken across the reef flat and then grounded adjacent to the wall. Once unloaded the barge was removed off site, the new wall was installed, old wall removed and then the barge was brought back to site for demobilisation works. The piling works involved having a 40 tonne crane suspending a 8 tonne pile hammer to complete the works. All works carried out in GBRMPA with no incidents or damage to the environment.
