While there is a succession of new dam construction projects in emerging countries, renovating and upgrading existing facilities is also a growing market in developed countries, whether in the United States or France. Capitalising on their expertise, notably specialist civil engineering, VINCI Construction companies are very active in these segments.

The market for the construction of large dams has been extremely buoyant in emerging countries over the past few years, driven by the combined effect of energy and water supply needs. 

There are an increasing number of projects in Africa, where just 7% of the hydropower potential is harnessed. The Group is doing very well on this competitive market. At the end of 2011 in Egypt, VINCI Construction Grands Projets won the contract for the construction of the new Assiut Dam worth €266 million. It includes the installation of two weirs on the Nile, a 32-megawatt hydroelectric plant, two locks and a four-lane bridge. 

“Following construction of the Naga Hammadi Dam in 2008, near Luxor, this structure proves that we have the capacity to return to the African continent on projects for which the proposal assessment method is more conducive to promoting our technical expertise,” says Jean-Pierre Dauban, Sector Manager at VINCI Construction Grands Projets. 

Two other hydroelectric projects are currently on the drawing board. One is in Uganda and the other is in Oman, where VINCI Construction Grands Projets already built the Wadi Dayqah Dam (main dam in roller-compacted concrete and a secondary embankment dam). Soletanche Bachy is equally active. Given the strength of the international market, the company is committed to strengthening its positions in Africa in the areas of dam foundations and waterproofing, relying in particular on its subsidiaries Dura Soletanche Bachy in southern Africa and Solsif in Morocco.

Key figures :
$370 million is the value of the contract won by Soletanche Bachy for the Wolf Creek Dam Seepage Rehabilitation Project in the United States. The largest contract won so far by this soil consolidation specialist.

66% of French dams were built between 1950 and 1990. Almost 200 of them require renovation work.

€108 million: the contract won by Dodin Campenon Bernard to build the Gavet underground structures is one of the largest recently signed in France for the renewal of hydraulic facilities.

"We are returning to Africa on projects for which the proposal assessment method is more conducive to promoting our technical expertise.” Jean-Pierre Dauban, Sector Manager at VINCI Construction Grands Projets.
