CEU à l'honneur

Spécifications complètes, compétitives et réalisables pour des solutions globales d'enveloppe de bâtiment dans un environnement de soumissions à bas prix.

L'infiltration d'eau est responsable de près de 90 % des litiges en construction. Cette intrusion concerne seulement 5 % de la surface totale de l'enveloppe. Le responsable est toujours le même : les transitions et les pénétrations. Le toit doit être relié au mur, le mur à la fondation, les ouvertures perforées au pare-air, l'isolation doit être installée sur le pare-air, et le revêtement doit être posé par-dessus... et ainsi de suite. Quel est le défi? Nous avons besoin que l'enveloppe fonctionne comme un ensemble cohérent, mais nous la spécifions, concevons, soumissionnons, réalisons une analyse de valeur, installons et inspectons par phases, ce qui implique toujours plusieurs fabricants et métiers. L’industrie se consolide clairement autour de solutions d'enveloppe totale fournies par trois à cinq grands groupes intégrés horizontalement, mais nous n’avons pas encore atteint le point de bascule : les spécifications et garanties d’enveloppe intégrée. Qu'est-ce qu'il faudra pour améliorer les choses?
