Special considerations should be taken into account when building on these sites Additional costs are generally incurred in building on such sites.Įxtremely reactive sites can experience extremely high amounts of ground movement. Highly reactive sites can experience a high level of ground movement. Moderately reactive sites can undergo moderate ground movement through moisture change, May be considered as your average site. Slightly reactive sites have only slight potential for ground movement through moisture change. Most shallow rock sites and some sand sites with little potential for movement through moisture change. Site classification is divided into various classes, dependent upon the “Ys” (potential movement). This includes the influence of “reactive” clay-based soils and/or the presence of fill, as well as the effect of “stable” materials such as dense sands or shallow rock. Potential surface movement and the resultant site classification are therefore consideration of the local depth of the zone of consideration of significant soil moisture variations and the entire ground profile. Methods adopted are in accordance with guidelines specified in AS 2870 – 2011, appendix D.
