Setting out implies that what it is drawn on the situation plan is marked on the ground. The setting out thus shows where the planned measure will end up on the site. Setting out  is sometimes called staking.

There are two types of setting out (demarcation), rough demarcation and fine demarcation. Rough demarcation is usually done before blasting, excavation or filling takes place and means that the corner of the future building is roughly marked. If the earthworks have already been carried out, a fine delineation is made before the construction work begins. Fine demarcation means that the corners of the building and any planned height are marked with sticks or on profiles. Staking is normally done by fine staking. 

The demarcation must be made after the building committee has given a go ahead notice.
