Kings Beach Rock Groyne Rehabilitation

The existing rock groyne at Kings Beach had succumbed to prevailing wave action and was no longer on its original alignment. Sunshine Coast Council engaged Projex Partners to provide engineering services and approvals for the design of a rehabilitated rock groyne (on the original footprint) and to assist in gaining statutory approvals associated with the construction of the structure.

Project due to start construction in 2017.

Mooloolaba Beach Sand Reclamation Pipeline

Projex Partners was engaged by Sunshine Coast Council to design, document and certify a buried Sand reclamation (dredging) pipeline. The pipeline was designed to allow rapid deployment of the dredge at the harbour mouth and to provide for sand re-nourishment to the Mooloolaba Beach. The project extended from the Mooloolaba Spit to the surf club at a distance of 1.5 km. Due to cost of the project, the project was staged to meet with councils budgetary constraints.

The pipeline was a 400DN polyethylene pipeline, selected for its toughness and flexibility. To provide a resilient design the pipeline was buried at 2m below the eroded beach level. This also served to improve public safety and aesthetics. To provide further resilience the pipeline was anchored along the beach to secure the pipeline; in the event the beach is eroded in extreme weather event.

The design featured regular buried discharge points (located by GPS) and breakout points to allow insertion of a booster pump.
