A consortium led by VINCI Construction signed a contract with the Gambia River Basin Development Organisation to build Sambangalou dam in southeast of Senegal, close to the Guinean border.
The €388 million (US$471.3 million) contract follows on from an initial phase conducting studies and preparatory work, which took place over a period of 18 months.
The 91-m-high dam will impound a reservoir that will provide water for renewable energy generation, irrigation of farmland and drinking water for surrounding districts. The powerhouse will have a capacity of 128 MW.
The work will begin in the first half of 2021 and is scheduled to last 48 months. At its peak, the project will employ 1,000 people recruited and trained locally.
Once the project has been delivered, the drinking water treatment station set up for the project will be remain in operation. The worksite buildings will be donated to schools. And engineers from the consortium will be involved in classes at the Kédougou technical high school.
The electricity generated by the dam will be supplied to of the four countries of the Gambia River Basin Development Organisation (The Gambia, Guinea, Guinea-Bissau and Senegal), where VINCI Energies is installing several hundred kilometers of high-voltage lines.
The consortium is composed of VINCI Construction Grands Projets (lead company) and VINCI Construction Terrassement, subsidiaries of VINCI Construction (75% of the consortium), and Andritz, an Austrian turbine manufacturer (25% of the consortium).
VINCI Construction is active on five continents, with more than 72,000 employees and 830 companies. The company has the capacity to intervene over the entire life cycle of a structure (finance, design, construction, maintenance) in eight sectors: buildings, functional structures, transport infrastructure, hydraulic engineering, renewable and nuclear energy, the environment, oil and gas sector, and mines.
