Congo
Brazzaville - Pointe-Noire
Client: Direction Générale des Grands Travaux
Contractor: China State Construction and Equipment Corporation
Inauguration: 1 March 2016

Project overview

535 km of newly paved, four-lane road now links Brazzaville, the capital city of the Republic of Congo, to Pointe-Noire, the second largest city and the economic capital of the country. Launched in 2007 by President Denis Sassou Nguesso, this 2 billion Euro construction works project was financed in part through a framework agreement on trade and economic cooperation between the Republic of Congo and the People's Republic of China.

The development of this strategic road, committed by the Congolese government, is a large-scope action that promotes national integration, the dynamism of trade and the country’s economy. It is also part of a regional strategy to make the Congo the gateway to the hinterland countries, and its port of Pointe-Noire a leading transhipment platform.

Our missions

As delegate project manager, Egis supervised all of the studies and construction works of this major project.

Faced with such an ambitious project, Egis deployed all of its expertise to ensure success in its role as delegate project manager, while maintaining very tight deadlines for implementation. With more than 202,000 plans examined and 1,250,000 geotechnical tests performed, Egis called on the best of its business, a monitoring team of over 170 people distributed across 535 km.

Egis decided to integrate into the project the protection and development of various noteworthy historical, geographical, geological, fauna and flora sites of interest. The most innovative technical decision made by Egis was the widespread use (12 million seeds) of a perennial grass called "Vetiver" to protect and stabilise berms in the Bateke sands area. This plant engineering solution, perfectly adapted to the environmental and socio-economic context of the country, can serve as an example for institutional or private developers in the Congo and can be regularly used to counter the erosion problems associated with the sandy soil in Africa.
