Deformation survey or deformation monitoring is defined as the systematic measurement and tracking of the alteration in the shape or dimensions of an object as a result of stresses induced by applied loads. The causes for deformation survey are changes in the bedrock, increase or decrease weight, changes of the material properties or outside influences. Deformation survey has the technique, calculation and instrument needed to monitor those structures. There are three types of monitoring uses to monitor structure. They are permanent monitoring, semi – permanent monitoring and epoch monitoring . Permanent monitoring is a long term of monitoring or continuous monitoring. Its required permanent observation of a structure using permanently installed instruments with recording facilities. Semi – permanent monitoring is identical to permanent monitoring but differs in intervals between recordings. Epoch monitoring uses geodetic or photogrammetric methods to determine the relative and or absolute positions of object that being motorize in time. The purpose of deformation survey is to ensure that whether there are movements taking place on the monitor structure and is it still safe to be used.
