Structural Monitoring

The ultra precise measurement of fixed points over time to calculate deformation.

With precise survey equipment and stringent control measures, sub millimetre movement by can be confidently detected in the data. With well presented charts, graphs and drawings, the data is effectively communicated to engineers for further analysis.

Surface analysis or flatness surveys of floor and ceiling slabs isolate and quantify problem areas. A 3D scanner is used to survey the soffit or floor area. The data is compared with the design surface to produce an elevation colour ramp and +/- deviation data.

The same principle is used to analyse vertical walls or any structure. The as measured point cloud is compared to the 3D model in Autodesk Revit with FARO As-Built.

Block wall study for potential wall tie failure – Lancaster

On this project the temporary prop is holding up a portal frame which presented significant deflection under its own weight during construction. The scanner was able to reveal how much each roof member had deformed.
