Deformation monitoring is the systematic and comprehensive measurement and tracking of the alteration in the shape and the dimensions of a civil engineering structure such as a bridge, dam and/or building; for this case Athi River Bridge deformation   which may be induced by applied loads of vehicles on transit and pedestrian use of the bridge.
