Projex Partners was engaged by Sunshine Coast Council to undertake the design and approvals of a new retaining wall at Penny Lane, Mooloolaba to protect from further Mooloolah River erosion including organising and lodgement of owner’s consent with DERM and a tidal works application for the proposed revetment wall construction.

West Coolum Boat Ramp
The West Coolum Boat Ramp is located on the shore of the Paynter River at the western end of West Coolum Road, west of the Sunshine Motorway.
The project included the reconstruction of a failed boat ramp with a precast boat ramp in accordance with TMR specifications for Sunshine Coast Council.
Projex Partners designed the boat ramp as well as concrete anchor beam, bedding material and shoulder design. Poor subgrade support required the use of piled foundations for the anchor beam..
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.
