In the construction sector, all structures are very critical assets. Even a minor failure can present a risk to people and to the environment and additionally can cause a substantial loss of money. Consequently, construction structures need to be monitored continuously.

In order to ensure the best quality and safe and durable operation of the BP-1413 highway’s viaduct over Can Fatjó (Cerdanyola del Vallès - Barcelona) in Spain, the project owner sought a reliable third-party inspection, verification, testing, and certification company.

In 2010, SGS Industrial Services in Spain was awarded a contract to provide comprehensive monitoring services of the viaduct due to its first-rate competence and expertise in projects of this kind.

A team of highly skilled SGS experts monitors the main stretch of the BP-1413 highway’s viaduct via two 25-meter long optic fibers and 50-meter transverse optic fiber located along and across the soffit of the prefabricated voussoirs, respectively. This system supplies real-time data needed to manage and control the viaduct to assure its safety and reliability. Furthermore, this technology can be applied as a detection warning system to prevent fissures in concrete structures and for research regarding their evolution and behavior.

Due to the precision and spatial high resolution of the optical fiber sensors, SGS Industrial Services obtains very reliable results. The SGS measurement of strains throughout the fiber allows for obtaining not only the strains in all points but also for the deflection at the interest points. With its extensive monitoring services, SGS controls the passing load of the highway’s viaduct and compares the resulting data with that obtained in the previous load test.

The analysis of the data gathered allows SGS’s experts to learn the viaduct’s behavior and take possible corrective actions to optimize the viaduct’s maintenance, repair, or replacement operations.

With SGS’s help, the quality, safety and reliability of the BP-1413 highway’s viaduct in Spain is guaranteed through continuous monitoring and to the client’s full satisfaction.
