Landslip repair - First Bay, Coolum

Dear community members,

Thank you for subscribing to project updates on the landslip repair works at First Bay, Coolum.

Project update: what’s happening behind the fencing?

While much of the work happening inside the exclusion zone isn’t visible from the outside, there’s been a lot of complex and technical progress made.

So far, around 65 metres of sheet piles have been installed. These are essential for safely digging out sections where we can build the concrete caps that sit on top of the foundation piles.

This process involves several steps: digging, installing soil nails (which help stabilise the ground), setting up formwork (the moulds for concrete), placing steel reinforcements, and finally pouring the concrete.

In total, 93 foundation piles have now been installed, each reaching approximately 18 metres deep into the ground.

One of the more challenging parts of the job has been the deep excavations needed for pile capping - some as deep as 3 metres. To make this possible, sheet piles had to be driven even deeper - 6 to 8 metres - through tough ground conditions.

Workers have had to navigate through layers of cobble, boulders and stiff clay with ironstone, which has slowed things down but is essential for long-term stability.

Weather, safety and site conditions

We know many of you are keeping a close eye on the progress, and we appreciate your patience as we navigate some tough conditions on site.

Because the work is happening close to nearby homes, apartments and underground utilities, we’ve installed vibration sensors around the site. These sensors are constantly monitoring construction activity to make sure nearby buildings remain safe and undamaged.

The site itself presents some unique challenges. Our team is working near a steep drop-off to the beach, which means extra care is needed to keep workers, vehicles and the public safe - especially during deep excavation works.

Weather has also played a big role in slowing things down. Over the past three months, we’ve recorded 75 to 130 mm of rain each month - that’s about 30 per cent more than average for this time of year. Wet conditions make it harder to carry out some of the more technical tasks safely and efficiently.

You may have noticed increased noise or vibration recently as we’ve delivered some of the more intensive parts of the project. We understand this can be disruptive and we’re sorry for the inconvenience.

A specialist consultant has confirmed that vibration and noise levels remain within safe and permitted limits. Council and contractors are continuing to monitor and manage these impacts closely to minimise disruption as much as possible.

We have worked with the Queensland Reconstruction Authority (QRA) to secure funding to repair this landslip and other damaged civil assets with assistance from the jointly funded Commonwealth-State Disaster Recovery Funding Arrangements (DRFA).

This is one of 15 landslips across the Sunshine Coast repaired using DRFA funding.
