Non-destructive testing techniques are often employed for periodic maintenance and reparation of construction works, especially for large-scale structures. These techniques can be applied during construction or even on existing structures. Out of the non-destructive testing techniques, infrared thermography is a powerful technique to investigate structural conditions and locate the damages because of the ability to visualize unseen subsurface delamination through thermal images. The technology of infrared detectors has significantly developed with high-quality products and acceptable prices. Therefore, the applications of the technique are feasible. This article introduces current infrared thermography techniques. Case studies have been implemented using passive infrared thermography for investigating construction works, such as buildings, warehouses, and bridges. The study has elucidated the applications of the method in detecting moisture penetration, area of insulation, energy loss, and subsurface delamination. A guide to passive thermography has been recommended for site inspection. Finally, common errors during thermal surveying are discussed to help engineers reduce unnecessary mistakes. |
