Project Management for Repair Works
Blue Bridge Structure
«Maintaining infrastructure, particularly civil engineering structures, in a condition that meets user needs in satisfactory safety conditions is a major challenge for operators.»
The provincial road no. 1075 is one of the Hautes-Alpes department’s main interregional routes. Given its role as a transit route and to develop the Hautes-Alpes, a modernization program has been defined for a period from 2015 extending beyond 2035.
The Haute Alpes department renews its trust in Lombardi Ingénierie for a project management mission to refurbish and repair the Pont Bleu bridge located in Saint Julien Beauchene.
The bridge, with a deck of prestressed slabs, crosses the Buech river with two spans of 20 meters.
Lombardi conducted an inventory of available data, including the Periodic Detailed Inspection of 2015, which revealed significant deterioration and therefore suggested additional investigations to better assess the damage.
The project includes the replacement of the bridge’s superstructure:
- Waterproofing,
- Road surfaces,
- Cornices,
- Retention structures,
- Sidewalks and curbs,
- Pavement joints,
- Abutments and their bosses.
In addition, repairing the concrete damaged by corrosion and filling a scouring under the central pillar.
In designing the project, we focused on planning methods to maintain traffic flow under the best conditions and to respect the client’s initial budget.
