Since the 2006 collapse of the De la Concorde overpass in Québec (Canada) and that of a bridge across the Mississippi River in Minneapolis (U.S.A.) in 2007, the exclusive use of visual inspection and coring as NDT techniques is of concern to managers, who now more than ever, value the importance of safety and objectivity in the decision-making process.
NDT techniques are objective, precise, and enable the proactive, efficient and safe management of civil engineering structures.
There are many reasons to seek the use of these techniques:
- On a new or healthy structure, the goal may be to estimate, verify or evaluate construction characteristics. The goal could also be to question its capacity to function adequately in a new environment (in cases where operating conditions or functional requirements have been modified, etc.).
- On a structure presumed to be damaged, NDT techniques can be used to confirm and evaluate
the extent of the damage.
- On a structure that is visibly damaged, NDT techniques can be used to characterize the damage (nature, extent, severity, etc.) and to evaluate the quality of repair work (eg. quality of an injection, adherence between two concretes).
According to our clients’ needs, AusculTech determines the most appropriate NDT programme, organizes and conducts the work required and analyzes the information collected and reformulates it into data that are useful for the decision-making process.
