AS 5181:2017 pdf free.Use and installation of turf as an erosion, nutrient and sediment control measure
This Standard does not address the growing, production or transportation of turf,biosecurity issues, or the hydraulic calculations that apply to the specification of turf for erosion, sediment and nutrient control purposes. It also does not apply to situations where seed is being sown at the specific work site, or to the use of washed turf for specialist applications (e.g. for sport fields).
The objective of this Standard is to provide land owners, developers, project personnel and contractors with requirements on how to select, install and maintain turf in order to prevent or control erosion, nutrient loss and sedimentation. This will minimize the adverse impacts of development works and change in land use on the surrounding and downstream environments.
This Standard recognizes that there are various methods for erosion, nutrient and sediment control such as turf, straw bales, jute logs or filter fences, etc. The control selected should be made after considering the relevant characteristics of the control (see Appendix A) and the specific site and use characteristics (see Section 3).
This Standard is intended to be specified in contracts and consents for all types of development, building and construction and maintenance works, from single residential homes through to major public infrastructure projects (e.g. roads, bridges, ports, urban precincts, parks and recreational facilities) and natural resource developments (e.g. mining).
A soil that has been excavated from the ground. Natural soil may be excavated natural material (ENM), recovered site soil (RSS), or virgin excavated natural material (VENM) as defined in Clauses 1.5.14.2 to 1.5.14.4.
NOTE: Natural soil could include topsoil and subsoil or quarried soil-like materials. Typically it will have a bulk density of greater than 1 .0 kg/L as determined in Appendix B of AS 4419.
The appearance created by the leaf structure of the turf.
NOTE: A fine texture is a large number of small leaves in a small area, and a coarse texture is a small number of large leaves in a small area.AS 5181 pdf free download.
