A method for tracking the deformation of structures is called deformation and movement monitoring (also known as deformation survey). Monitoring for deformation and movement measures and tracks any changes to a building’s dimensions or shape.
Buildings or landscaped areas can be subject to movement such as land settlement or subsidence resulting in the need for one of three surveys, to check ground, floor and wall levels. Depending on the project, a Subsidence Survey, a Levelling Survey or a Settlement Survey is required.
Catching movement early on ensures remedial costs are kept to a minimum and so pinpointing this with absolute accuracy is imperative. An initial survey models and contours the face of the wall or floor. This highlights any movement or deformation by establishing a series of permanent points along it. If the levels appear to be moving, then a monitoring survey is implemented to see how far and how quickly the movement is occurring.
We’ve engaged Powers on survey projects in the past and have always been very impressed with their efficiency and professionalism. They share our ambition and we were able to communicate directly with the owner and discuss our requirements for this complex and large scale project.
