Project Currumbin Ridge
Project Engineer Bret Arthur
Medium density residential development (sixty nine individual units and duplex). The site is very steep with a history of slope instability. Construction of the access roads to service each unit required extensive cut and filling to achieve required grades. Access for construction was very restricted due to only one entry location and the steep narrow roads proposed.
The roads were designed with cut and fill to minimise excessive earthworks. To stabilise the slopes, engineer designed masonry retaining walls with deep piles were adopted. This enabled minimum excavation into the existing slopes while maintaining a strong and durable retaining system.
The finished stage one area now enables a sealed all weather access to all areas of the site with stabilised batters for the construction of future dwellings. The roadworks and stormwater drainage installed has helped control erosion on the site and managed the discharge of stormwater from the site in such a manner as to not effect downstream properties.
