Veidekke has delivered asphalt core competence and advisory for a major dam in western Brazil.

The 3700 Megawatt project is being developed by Energia Sustentável do Brazil and with Camargo Corrêa as contractor for all civil works. The area has a high precipitation during the rainy season, November to April. The central dam across the river was the critical part in the schedule. In order to complete this during the rainy season, an asphalt core dam was a natural choice.

The dam with a crest length of approximately 980 m has two distinct depressions in the profile. In order to complete the work in a minimum of time, it was decided to perform the asphalt works with two core paving machines and two working teams.

Camargo Corrêa supplied all personnel and standard machinery including asphalt plant, while Veidekke supplied expertise, special machinery and supervision on site.

Veidekke's work on the dam began in March 2012 and the work was completed December 2012.
