Construction of the 3 railway bridges – Bonneuil-sur-Marne

End of the first part of the works for the construction of the 3 railway bridges across the RN604 road, at Bonneuil sur Marne, for the French railway infrastructure organization SNCF Réseau.

After having performed successfull piling trials in 2018 to confirm the technical solution, LEDUC gathered its strengths with Maïa Sonnier, Razel Bec, and Maïa Fondations to win the final tender for this essential project.

All the personnel worked on day or night shifts to ensure a seamless progress of the very long twin HZ retaining walls, a first for this kind of structure !

We’d like to warmly thank all our teams who did a remarkable job right in time to hand-over back the rail tracks to passengers’ traffic.

Cotonou power substation – Benin

First mission in Benin completed by MOVAX mobilised at Cotonou site !

The sheet pile wall was installed at Cotonou Substation « de l’Ancien Pont » for Eiffages Energies Systèmes were achieved in March 2021.

The 45 m sheetpile wall was installed by LEDUC TP’ s MOVAX side pile driver mounted on a powerfull PC 350 KOMATSU in only few days.

The fast track mobilisation was made possible by the support of the Senegalese branch of LEDUC TP as well as Vernon’s Engineering office..


Breaking the record at Bargny site ! – Senegal

Works are progressing at a high pace at Bargny new Mineral harbour jetty site : the massive 15 m wide concrete deck has now reached 1000 m and is being installed at the impressive speed of 90 m per week !

The site works have started in 2019 with the construction within the Bargny-Sendou free trade zone of a spirally welded pile fabrication shop, together with a state-of-the-art welding shop ( including welding robots, plasma cutting bench, ..) and a reinforced concrete prefabrication yard.

The aim of the jetty will be to link the future Mineral bulk carrier berthing dock with the shore, enabling the operation of the latest generation of vessels, either for importation of bulk products but also for exporting Senegal productions such as Phosphates, Minerals, iron ore, …

Fitted with several handling conveyors and two circulation lanes, the jetty will enable the safe and efficient transport of vessel’s cargo up to the warehousing and storage facilities.

This Jetty is a key element of SMP’s (Senegal Minergy Port) harbour development strategy to tackle two major challenges : the constant mineral bulk traffic increase and the congestion of Dakar historic harbour.




KONTA Mineral Jetty – Guinea

Mission complete for LEDUC in Guinea with the delivery of the new KONTA Mineral bulk Terminal in record time and despite the restrictions imposed by the COVID-19 !

Site works started in August 2020, and finished by end October, just in time to receive the bulk mineral handling system (conveyors, loading arm).

This Terminal was designed by Marine Contracting and Infrastructure (MCI) to load barges up to 10,000 T on the coastal river next to the open ocean.

LEDUC was selected by MCI for the construction of the marine infrastructures : detailed Design, procurement and fabrication, transport and installation of a 50 m jetty and mooring/berting Dolphins.

This project is part of MCI’s development strategy in Bauxite mineral ressources in Guinea. MCI is a subsidiary of the GHANTOOT Group (UAE).



AVEON OFFSHORE Berth – Nigeria

Another success for LEDUC’s Construction teams : completion of AVEON OFFSHORE heavy berth in Port Harcourt (Nigeria), despite the restrictions imposed by the pandemic COVID-19 !

Site works started early 2020, and were finished by end of June, just in time before the rainy season.

This heavy quay was designed by IOA to support up to 450T capacity cranes, as well as multiwheel loaders used for the transfer of offshore decks from the fabrication yard up to the transport barges.

LEDUC was selected by AVEON OFFSHORE for the construction of the quaywalls (Combiwall and Pile-to-Pile) and the installation of deep foundations for the quay slab and crane tracks (H-piles and tubular piles).

This project was done in continuation of the slipway built in 2016 at the same location by LEDUC for the TOTAL EGINA oilfield SPM buoy launching, « the largest buoy in the world » (2500T).
