Construction of a 3,000m2 bio-retention basin with a storage capacity of 3ML for a new land division in Reid; including installation of pipework, outfall structures and a gross-pollutant trap. The project scope included a considerable bulk earthworks component of 2,000m3 cut-to-fill and importation of a further 7,000m3 of fill. The basin included a compacted clay liner with multiple drainage layers comprised of imported aggregate with layers of coarse sand. Installation of 3,000m2 of JutemasterTM matting for batter protection and weed control and 1,100m2 of GrassrootsTM revegetation and erosion control matting was also required. Additional works included placement of topsoil for planting of aquatic and dryland plants and approx. 4,300m2 of hydro-seeding.
The construction of two professional size football/cricket ovals incorporating subsoil drainage, bulk earthworks, gabion retaining walls, and importation of 12,000t of special blend loam. The project scope also included an irrigation system and cricket pitch. All playing surfaces were finished utilising GPS & TPS machine control.
Construction of two detention basins totalling 5,000m2 at two separate locations approximately 9km apart. The first location being at the Torrens Linear Park, Dernancourt and the second location at Kingfisher Reserve, Modbury Heights. This project involved the bulk cut-to-fill and cut-to-dispose of approximately 12,000m3 of spoil including the construction of a compacted clay liner. Additional works included construction of rubbled path ways, precast concrete boardwalks, outfall structures and pipework to feed the 'Waterproofing Northern Adelaide' ASR scheme.
Damming of the existing creek and realignment of the 140m x 10m x 3m waterway, cut to fill on site of 30,000m3, gabions, clay lining, rock drop structures. Major erosion and sediment control procedures were required to ensure protection of the native flora and fauna.
