Bridges and structures
Fugro Aperio has the capability and engineering expertise to apply a wide range of non-destructive techniques supported by targeted intrusive testing. Relevant investigative methods include, visual inspection, half cell potential, resistivity, thermal imaging, ultrasonics, radiography and GPR.
Surveying a masonry arch bridge with ground penetrating radar to determine construction and condition
Compared to 'traditional' inspection and investigation methods such as exposure of the structure and material sampling, non destructive investigation methods are typically quicker to establish on site, require less complicated access arrangements and are therefore less disruptive to the user. Increasing use is being made, for example, of rope access methods to work on tall structures and the underside of bridges without expensive mechanical plant.

Reporting bridge and structures information
Reporting formats vary with different applications and tests. In some cases, instant results are required, for example in mapping duct positions to enable targeted drilling as part of intrusive post-tensioned bridge investigations. In most cases all data is removed from site for computer-based analysis and processing with findings presented on CAD drawings with a factual or interpretative report including annotated samples of data.
