What is the purpose of monitoring surveys?

A monitoring survey will detect the movement, if any, of a building or structure progressively over time through 3D laser scanning technology. Red Laser, provides extensive building movement monitoring surveys that will determine any changes to a building or structure. The latest 3D laser scanning technology and building movement monitoring equipment, such as laser scanners for scanning the whole structure, total stations which accurately measure angles and distances, tilt sensors for measurement of angles and send data to a central hub at regular intervals, and Crack Gauges or monitoring studs for crack monitoring and detection of motion. Our building movement monitoring surveys can quantify and report the amount of movement and any changes that might have happened over time.

For a building or structure, movement may be triggered by adjacent site ground works, including excavations and drilling works, or result from natural ground movement and settlement over time. This surveying technique is also applicable in monitoring the deflection or deformation of structures due to load, such as a bridge or supporting beam.

In many cases, this type of survey is performed on a structure following the recommendation of a structural engineer upon determining that it is at a risk of moving. The survey will help you notice any early indications of movement by a building or structure to avoid escalation. Conducting a monitoring survey on a building or structure near a heavy construction site, such as basement excavation, piling, or demolition, is appropriate.
