STEEL AND BUILDING STRUCTURES

Examination of various structures focuses on the condition of steel frames both during the construction stage and in operation. The owner/operator is responsible for technical condition of the structures that include among other stairways, stepping grates, safety elements such as rails etc. Documentation is often missing for older structures, sufficient anti-corrosion protection does not exist, coupling is missing, welded joints are damaged etc.

Basic inspection method is the direct examination. The examination focuses on the condition of structural elements, including concrete feet, coupling materials and anti-corrosion protection. Besides other things the coating layer and structural element thickness can be measured, non-destructive inspections of welded joints done using ultrasound, magnetic particles, irradiation, capillary or electromagnetic methods, such as array probes.
