Selon diff\u00e9rentes \u00e9tudes internationales men\u00e9es sur les infrastructures de transport, les co\u00fbts de neuf projets sur dix sont sous-estim\u00e9s. Ainsi, les co\u00fbts finaux sont en moyenne 30 % plus \u00e9lev\u00e9s que les co\u00fbts estim\u00e9s lors de l\u2019approbation des projets. Cette sous-estimation syst\u00e9matique des co\u00fbts concerne tout type de projet. Dans le domaine des infrastructures, la construction d\u2019ouvrages souterrains est particuli\u00e8rement co\u00fbteuse et complexe, notamment du point de vue de la gestion des risques et des incertitudes. Et pour ce type sp\u00e9cifique d\u2019ouvrage, le risque de d\u00e9passement des co\u00fbts est encore plus fort et s\u2019\u00e9l\u00e8ve en moyenne \u00e0 35 %.<\/p>\n","protected":false},"featured_media":0,"menu_order":0,"template":"","audit_category":[47],"audit_type":[100],"class_list":["post-6255","audit","type-audit","status-publish","hentry","audit_category-transports-et-environnement","audit_type-evaluation"],"acf":{"audit_lang":[{"lang":"f"}],"audit_numbers":[{"audit_number":"7367"}],"audit_office":[7959],"audit_office_text":"","audit_date":"20091201","bgo":false,"keywords":"\u00e9tudes internationales, les co\u00fbts de neuf projets, les infrastructures de transport, les co\u00fbts finaux, l\u2019approbation des projets, sous-estimation syst\u00e9matique des co\u00fbts, la construction d\u2019ouvrages souterrains, le risque de d\u00e9passement des co\u00fbts","audit_office_local":""},"yoast_head":"\nConstruction de tunnels autoroutiers: l'\u00e9volution des co\u00fbts est-elle sous contr\u00f4le?
