Bulking refers to the expansion of materials after excavation where shrinkage refers to the opposite effect when material is compacted. Volume analysis of stockpiles and cut and fill exercises for earthworks should be mindful of the materials being measured and whether or not correction factors are to be applied.

A datum is a reference point or surface. Heights (elevations) of other points on the map or survey are relative to the datum. Most surveys in mainland UK use mean sea level as a 0.00 datum, so a level of 50.00 means 50 meters above mean sea level. Local arbitrary datums are sometimes used instead, such as a finished floor level or a man hole cover frame.

A monitoring project will typically consist of an initial installation of a control network placed on stable monuments outside of the area of interest. This is followed by careful installation and recording of the position and height of monitoring points. These are placed on features of interest within the monitoring area, or the entire monitoring area will be scanned with a 3d scanner. A series of subsequent monitoring surveys are carried out at prescribed intervals to repeat the measurement process and monitor changes in coordinates, representing movement and deflection.
