Description
L'ancien arsenal protégé sera transformé et agrandi pour accueillir le nouveau musée d'histoire naturel. Rehaussement du bâtiment de 1 niveau.
Travaux de l'entreprise
La planification du projet comprend le renforcement de la charpente existante, la rénovation de certaines parties de la structure en place ainsi que la réalisation d’une nouvelle structure en bois destinée à une surélévation. Le projet s’est déroulé en quatre phases.
Travaux de l'entreprise
1. Renforcement de l’ensemble de la structure porteuse existante à l’aide d’assemblages par tiges filetées collées, ainsi que par la mise en place d’inserts en profilés métalliques à l’intérieur des poteaux en bois existants. Cette étape incluait également l’étayage de chacun des poteaux.
2. Création de liaisons entre les solives et les sommiers des planchers existants avec le béton, afin de former des dalles mixtes bois-béton sur l’ensemble des planchers.
3. Nouveau plancher au niveau 1 en bois massif provenant des forêts fribourgeoises, destiné à accueillir la future surélévation.
4. Construction de la surélévation en structure bois lamellé-collé d’origine suisse. La structure porteuse se distingue par ses parois composées de poteaux en W ainsi que par ses fermes en forme de losange, présentant une portée de 20 mètres. Ainsi que la réalisation de tout le complexe isolant de la surélévation.
