It introduces the other parts of the standard, which will be used together with Part 1.It is applicable to all types of earth-structures, whatever their intended use is (roads, railways, airfields, waterways, buildings, landfills, tailing dams, etc.), except where listed below:- some specific types of works such as the execution of trenches and small earthworks may be organized using simplified or specific rules;- some structures, such as dykes and dams, need earthworks which have specific design and construction requirements: these may extend beyond the rules of this standard.
