Mooloolaba Caravan Park Revetment Wall

Sunshine Coast Council requested Projex Partners undertake design and approvals of refurbishment of the existing rock wall protecting the caravan park on Mooloolaba Beach foreshore.

This project is currently on hold pending outcomes of Sunshine Coast Council’s Mooloolaba foreshore planning.

Shelley Beach Revetment Wall, Caloundra

Projex Partners was engaged by Sunshine Coast Council to undertake detailed design of a new rock revetment wall to protect the existing vegetation and replace the rock pitching around the stormwater pipe outlet with a grouted rock pitched wall. Design included sections of dry stack and grouted rock pitching and extended from the existing fence north of the pipe outlet to the existing rock revetment wall on the southern side of the pipe outlet.

The project is due to start construction in late 2016.

Maloja Boat Ramp, Caloundra

Sunshine Coast Council requested Projex Partners undertake survey, concept and detailed design for rehabilitation of the existing boat ramp.

The project required the design of a topping slab over the existing concrete slab as well as new toe planks below the tide line.

The design had to allow for the extremely harsh conditions of the coastal environment.

River Esplanade Revetment Wall, Mooloolaba

Projex Partners was engaged by Sunshine Coast Council to undertake detailed design and approvals for a grouted rock pitched revetment wall at River Esplanade including detailing of the pipe outlet through the revetment wall, construction cost estimate and review of geotechnical report.

The design was consistent with similar designs provided to Council for the Bindaree Crescent and Penny Lane projects.

The project is due to start construction in late 2016.

Penny Lane Revetment Wall, Mooloolaba

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.
