Bouygues Travaux Publics, Quille Construction and DTP  handled the civil engineering for EDF's EPR reactor in Flamanville, a third-generation European nuclear reactor. The site comprises 12 industrial buildings, including the machine room and the containment structure in the reactor building. With 400,000 m³ of concrete poured and 50,000 tonnes of supporting elements assembled (yielding a weight seven times greater than that of the Eiffel Tower), this is a site of extraordinary proportions. The reactor dome installed in July 2013 weighs 240 tonnes on its own!
