[vc_row][vc_column][vc_column_text]\n

Transportation infrastructure is an essential part of our economic, cultural and historical heritage. Engineering structures (bridges, viaducts, tunnels, retaining walls, dykes, quays, booms, footbridges, etc.), which are an integral part of these infrastructures, are indispensable to our daily lives and to the attractiveness of our regions. They also represent a high symbolic value of our collective engineering capacity.<\/h3>\n

As with all constructions, the lifespan of engineering structures is limited by their ageing, whether natural or accelerated by their environment and operating conditions. Their ruin, always spectacular, is often tragic. Genoa in 2018, Mirepoix in 2019 and Aulla in 2020 are all reminders that the monitoring and maintenance of engineering structures are essential to ensure our safety and the full exploitation of their potential.<\/p>\n

On this page, you’ll first discover the challenges of surveillance, then a panorama of the skills and solutions deployed by SITES.

Bridges, viaducts, footbridges, tunnels… Engineering structures that require increased surveillance<\/span><\/h6>\n

Whether old or new, road, rail, river, port and airport infrastructures are the backbone of the mobility of people and goods. Over time, their structures, subjected to a rapidly changing environment and sometimes to overuse, develop various pathologies more or less rapidly. Increased surveillance is therefore essential to monitor their evolution with the utmost care. Safety, sustainability, optimized operation, maintenance and upkeep costs are the current challenges facing managers, owners and operators of these infrastructures.<\/p>\n

The collapse of the Morandi bridge in Genoa on August 14, 2018, sparked strong emotions around the world and rekindled debates on the state of France’s engineering structures heritage. In order to reassess how they are monitored and maintained, at the end of 2018 the French Senate set up a fact-finding mission dedicated to bridge safety. The Senate committee’s findings are clear-cut.[\/vc_column_text][vc_message message_box_style=”solid” style=”square” message_box_color=”white” icon_fontawesome=”fa fa-commenting-o” css=”.vc_custom_1588599442135{margin-top: 30px !important;margin-bottom: 30px !important;padding-top: 20px !important;padding-bottom: 20px !important;background-color: #fcfcfc !important;}”]\n

\u00ab At the end of its work, the fact-finding mission has made a number of worrying observations about bridge management in France:<\/span><\/p>\n

– The exact number of road bridges in France is not known;<\/strong><\/span><\/p>\n

– At least 25,000 bridges are in poor structural condition, posing safety and availability problems for users;<\/strong><\/span><\/p>\n

– The deterioration of the bridges is due to the ageing of the assets and chronic underinvestment in the maintenance of these structures;<\/strong><\/span><\/p>\n

– The problem is even more worrying when it comes to communes and inter-communal bodies, some of which are unaware of the condition of their bridges, and sometimes even of their number, are not equipped to manage them, and face major financial difficulties in maintaining them.. \u00bb<\/strong><\/span><\/p>\n

Guidelines and methodology for monitoring engineering structures<\/span><\/h6>\n

The collapse of the Wilson Bridge in Tours in 1979 triggered the introduction of a technical reference specifically dedicated to the monitoring and maintenance of engineering structures: ITSEOA (Technical Instruction for the Supervision and Maintenance of Engineering Structures).
\nFrom a technical point of view, there is currently a documentary database listing and describing precisely, for each type of structure, the majority of known pathologies in terms of causes and severity. This database is regularly updated to incorporate feedback and innovations in terms of construction techniques, methods and materials.
\nMonitoring methods and organization evolve regularly to take account of economic realities, innovations and the wide diversity of managers, operators and owners in terms of responsibility and asset size.
\nAs a player in these developments, SITES is involved in a number of professional associations and training organizations.

SITES and infrastructure monitoring<\/span><\/h6>\n

Since 1984, SITES has been providing solutions to monitoring issues. We offer all stakeholders in exceptional and current structural assets (owners, builders, managers, operators and insurers) studies, methods and solutions to assess and monitor the state of health of their structures over time, with several aims in mind: to guarantee the safety and durability of their use, to avoid any unexpected interruption of use and any costly unanticipated repairs.<\/p>\n

Over the years, SITES and its teams have developed a range of tools and skills to optimize the expertise, surveillance, follow-up and real-time monitoring of structures.

Example of a structural assessment of a cable-stayed bridge<\/span><\/h6>\n

When carrying out a structural assessment of a cable-stayed bridge, SITES applies a wide range of skills: detailed inspection, measurement of support settlement and cable-stay tension.<\/p>\n

This assessment is accompanied by recommendations that enable the operator to ensure the safety and durability of his engineering structures.

During the shutdowns, SITES implemented a system to thoroughly inspect 2325m of tunnel, including two traffic levels, air extraction\/blowing ducts in the lower and upper sections, i.e. almost 9300 prefabricated reinforced concrete voussoirs and 2900 support devices.

ScanTubes\u00ae: 3D surveying and photogrammetric inspection of tubular structures<\/span><\/h6>\n

The ScanTubes\u00ae tool developed by SITES scans horizontal or vertical tubular structures, automatically taking high-resolution 360\u00b0 photos and capturing the structure’s 3D geometry via photogrammetric processing.<\/p>\n

The tool is pushed onto a road or rail cart, or suspended from the end of a cable. It dynamically captures images from 12 calibrated digital industrial cameras.<\/p>\n

The data acquired can be used to produce digital twins of the structures, enabling precise mapping of defects, giving an opinion on the condition of the structures and monitoring their ageing over time.

Drones to overcome constraints<\/span><\/h6>\n

For over 30 years, SITES has been developing special remote inspection equipment to make it easier to observe structures, while limiting the need for special equipment (scaffolding, rope access, gondolas, etc.). In this context, the drone makes it possible to overcome these difficulties, limit masked areas and get close enough to the structure to detect any disorders.<\/p>\n

SITES has a fleet of drones that can be adapted to suit the needs, structures and environments investigated. Specially developed by SITES for the inspection of large structures (dams, viaducts, chimneys, cooling towers, etc.), these drones carry high-definition photographic sensors. In addition to all the systems required for stable, safe flight, they are fitted with servo-controlled rangefinders to maintain a constant distance from the structure and ensure consistent survey quality.

Example of a drone inspection<\/span><\/h6>\n

On behalf of the Conseil D\u00e9partemental de la C\u00f4te d’Or, SITES’ civil engineering experts carried out a Periodic Detailed Inspection of masonry viaducts. Exhaustive HD mapping to scale enabled the current condition of the structure to be assessed, and any repairs to be accurately dimensioned for the immediate benefit of the project owner.<\/p>\n

Field surveys carried out by drone improve worker safety by limiting the use of special access equipment (cherry pickers or rope access) and the time required to mobilize the structure, thereby reducing inconvenience to users. In the future, this digital archive will unequivocally support the study of structural evolution kinetics, enabling us to anticipate and plan maintenance operations at lower cost.
