4. Construction Methodology
The Reef patches are to be comprised of locally sourced igneous porphyry rock (the
substrate) with a size range of 100mm to 600mm.
The substrate will be loaded onto the barge using a Posi - track loader and excavator, the
barge then travels to the build site which will have individual patches marked out using a
combination of marker buoys and star pickets, located using GPS.
Once on site the barge uses steel spuds rather than anchors to ensure precise placement of
the barge and to eliminate both swing and potential environmental damage from anchor
chains.
The barge is then unloaded using an excavator with a customised thumb and blade
attachment which allows us to pick up the rock and place it into the water precisely and
carefully, minimising plumes.
