Ocean Reef Marina Breakwaters

The JV constructed the breakwater and revetment structures with a combined length of 2km of seawall and 1km of revetment wall. The work scope included reuse of existing breakwater material; placement of geotextile, limestone core armour and granite armour; and excavation of dredging areas. Material supply was the biggest challenge for the project, with the management of importing 1.25 million tonnes of rock across more than 30 delivery sites impacting the delivery schedule. Working with inclement weather and completing significant trucking and earthworks within an urbanised area were also challenges.
