Our projects

Our know-how in the maritime construction industry allows intervening for the maintenance, extension, or creation of maritime infrastructure. Since the 2000s, we have been operating around the Mediterranean as well as in Africa on commercial ports and quays, military ports, mineral or oil terminals, marinas, and shipyards.

Alone or in partnership, we work on major projects in France and abroad. We are involved in projects ranging from 1 to 100 million euros.

The quality of the projects we design and built, as well as the quality of the relationship we maintain with our clients, lead to a close and trusting collaboration.

Cofferdams are temporary watertight structures that encircle the construction site so that dry construction work can be carried out. Temporary booms are a kind of temporary bridge that allow the construction of permanent structures without the use of maritime means. Negri intervenes right from the design phase to optimize the construction of these temporary structures.
