• 716.4m of stormwater drainage lines
• Major stormwater structures
• 1157m of sewer reticulation (including over 100m at 5.0m+ depth) constructed using wellpoint dewatering
• 901.2m of water reticulation
• Construction of three bio filtration basins involving base geotextile layer, drainage aggregate layer, transition sand layer and bio filtration sand top layer, with sacrificial geotextile, topsoil and turf


• Management of the site required specific environmental measures including silt curtains and water quality testing due to works extending past the lake edge.
• Provide temporary two coat seal diversion track alongside Rio Vista Blv to allow through traffic to flow during the construction and upgrade of the Dunlop Crt/ Rio Vista Blv roundabout.
