Geotextile design options selected for Maroochy groyne project tender


Sunshine Coast Council’s coastal engineers work at the Water Research Laboratory at UNSW in Manly to comprehensively test geotextile design structures.

After embarking on a 12-month contract to research and develop suitable options for the groyne renewal at Maroochy River, two preferred designs for the river mouth’s geotextile containers have been selected.

This extensive research and design development follows the award-winning community engagement process to determine the most suitable upgrade option for the Maroochy Groyne Field Renewal Project, designed to protect the Cotton Tree precinct from erosion.

The two preferred design options will now be key components of the construction tender, which goes to market on Saturday, November 23.

Sunshine Coast Council’s Coastal Engineer Georgia Keeshan said the tender process would request pricing for both a herringbone design and stretcher bond pattern for the geotextile structures, with the final chosen option considering both constructability and value for money.

“Our team has taken the community’s feedback on board and, with help from the Maroochy River Estuary Consultation Group (MRECG), we took the opportunity to investigate the best and latest technology options to help protect this distinct and highly valued waterway,” Ms Keeshan said.

“In addition to extensive consultation with geotextile manufacturers and other engineers from the Water Research Laboratory at the University of New South Wales, our coastal team undertook physical modelling of the different design structures and tested them using an in situ structure.”

The successful tender will be awarded late February 2020 after a detailed assessment process and it is expected construction will start late April 2020.

Construction works will be undertaken in two stages, with Stage 1 focusing on the two northern-most groynes and the seawall surrounding the Cotton Tree Holiday Park.

This initial work is expected to last approximately six months, depending on weather and tidal conditions.

Stage 2 will start in 2021 on the two southern-most groynes as well as a ramp to facilitate emergency access to the north of the site.
