Specifies design methods and loads for use in the structural design of walking tracks. It covers boardwalks, galleries, pedestrian bridges (including wire crossings), platforms (for viewing), ladders, stairways, stiles and barriers.

This Standard specifies requirements for the structural design of walking track structures, to protect natural and cultural assets and for use as aids to recreation in outdoor areas where the environment is the focus of recreational activities.The general design of tracks including their layout, environmental management, aesthetics, and pathway design is not covered by this Standard.The structural design criteria given in this Standard take into account factors such as location, expected use and type of recreational opportunity through reference to the track classifications given in AS 2156.1.The following structures and parts of structures are covered in this Standard:(a) Boardwalks.(b) Galleries.(c) Pedestrian bridges, including wire crossings. (d) Platforms (for viewing).(e) Barriers.(f) Stairways.(g) Ladders.(h) Stiles.This Standard does not cover structures intended to carry livestock (e.g. horses) or vehicles (including bicycles and light maintenance vehicles).NOTES: 1 This Standard is intended primarily to be applied to new structures; however, existing structures may be assessed using the criteria given in this Standard. The track class should be specified before structural design of new structures commences.2 For structures such as huts, shelters, barbecues, toilets, vehicle bridges, heritage structures, lookout towers, jetties and launch ramps, the approving authority should be referred to.3 Background information and guidance for the use of this Standard is given in Appendix A.4 Information on durability is given in Appendix B.5 Information on design for light maintenance vehicles is given in Appendix C.
