Project Overview / Description

Port of Townsville engaged CivilPlus Constructions for the shortening and reconstruction of the eastern breakwater at the Townsville Port. This project involved the reduction of the current length of the Eastern Breakwater, situated within the inner harbor of the Port.

This was achieved by extracting rock and bed material using long reach excavators and articulated dump trucks. Demolition of approximately 115m of existing breakwater was completed during periods of low tides, and a new 50m round head was construction with imported material. Overall this allowed dredging of the shipping channel at the end of the shortened breakwater as part of POTL’s $251 million Channel Upgrade.

Project Features:

    • Removal of existing Breakwater, approximately 10,000m³ of material
    • Placement of approximately 500 tonne of Core Rock
    • Placement of approximately 1,200 tonne of Secondary Armourstone
    • Placement of approximately 3,000 tonne of Primary Armoustone (2t to 5t rock)
    • Grouting works between old and new breakwater interface.
