• Major earthworks across the Airport site. This involves taking earth from the peaks to fill the low points to level the site ready for construction

• Excavation using surface miner to break up hard rock material on the site. The surface miner works follow the ridge line along the old The Northern Road alignment at the western end of the site

• Importation of recycled sandstone material. This material is sourced from the WestConnex and Sydney Metro Projects and is repurposed across the site in a sustainability partnership between the projects. The high-quality sandstone is used as a supportive layer under the runway and taxiways

• Water treatment and water discharging activities. Excess rainwater captured in one of 15 temporary water basins located around the site is treated and discharged off the site. Where possible the captured water is used for dust suppression on the site

• Installation of permanent airport drainage across the site

• Ongoing surveying of site is undertaken to ensure each layer of earth is at the correct level

• Permanent landscaping - topsoil stockpiled in the early stages of the Major Earthworks project is now being respread around different parts of the project, which will form the base to grow vegetation

• Heavy machinery maintenance is carried out in two workshops, as well as in the field around the site
