As a collection of the useful elements for projects preparation & implementation and buildings markets in France, the Reef (which stands for Recueil des Eléments utiles à l’Etablissement et l’exécution des projets et marchés de bâtiments en France) is the technical/regulatory reference database for all players in the construction sector.
