Introduction<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Les travaux faisant l\u2019objet de ce contrat consistaient principalement en l\u2019am\u00e9nagement d\u2019un site de disposition des neiges us\u00e9es. Ceux-ci comprenaient notamment des travaux d\u2019excavation, de remblayage, de compaction, de terrassement, d\u2019isolation, de g\u00e9nie civil ainsi que la mise en place d\u2019ouvrages de gestion et d\u2019\u00e9vacuation des eaux pluviales.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

1. D\u00e9broussaillage, enl\u00e8vement des souches et mise en forme initiale\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

La premi\u00e8re phase a consist\u00e9 \u00e0 pr\u00e9parer le terrain pour la construction. Les \u00e9quipes ont d\u00e9broussaill\u00e9, enlev\u00e9 les souches et d\u00e9cap\u00e9 la terre v\u00e9g\u00e9tale avant d\u2019entamer les travaux de terrassement qui d\u00e9finissent l\u2019emprise du bassin. Une planification rigoureuse \u00e0 cette \u00e9tape est essentielle : la bonne r\u00e9alisation des d\u00e9blais, des pentes et des voies d\u2019acc\u00e8s d\u00e8s le d\u00e9part \u00e9vite aux diff\u00e9rents corps de m\u00e9tier d\u2019avoir \u00e0 effectuer des travaux suppl\u00e9mentaires co\u00fbteux.<\/p>

2. Installation des conduites d\u2019\u00e9gout pluvial et de BNQ\n\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Une fois la dalle de fondation r\u00e9alis\u00e9e, nous avons proc\u00e9d\u00e9 \u00e0 l\u2019installation du r\u00e9seau d\u2019eaux pluviales. Des conduites de grand diam\u00e8tre, certifi\u00e9es BNQ, ont \u00e9t\u00e9 install\u00e9es dans des tranch\u00e9es afin de capter les eaux de fonte et de les acheminer vers un syst\u00e8me de rejet contr\u00f4l\u00e9. Chaque joint a \u00e9t\u00e9 inspect\u00e9 et scell\u00e9 conform\u00e9ment aux sp\u00e9cifications pour garantir une performance durable malgr\u00e9 les cycles de gel-d\u00e9gel du Qu\u00e9bec.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t\t\t\t\t\t

Une fois le r\u00e9seau souterrain en place, l\u2019\u00e9quipe de terrassement est revenue pour peaufiner la g\u00e9om\u00e9trie du bassin. Le nivellement, le compactage et la v\u00e9rification des pentes ont \u00e9t\u00e9 effectu\u00e9s en plusieurs \u00e9tapes successives afin d\u2019atteindre les profils pr\u00e9vus. L\u2019obtention d\u2019un compactage homog\u00e8ne \u00e0 cette \u00e9tape influe directement sur la bonne mise en place de la g\u00e9omembrane lors de l\u2019\u00e9tape suivante.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t\t\t\t\t\t

Une g\u00e9omembrane soud\u00e9e a \u00e9t\u00e9 d\u00e9ploy\u00e9e sur l\u2019ensemble du bassin afin de contenir int\u00e9gralement les eaux de fonte et les s\u00e9diments qu\u2019elles transportent. Les panneaux ont \u00e9t\u00e9 soud\u00e9s \u00e0 chaud sur place, leur \u00e9tanch\u00e9it\u00e9 a \u00e9t\u00e9 v\u00e9rifi\u00e9e, puis ils ont \u00e9t\u00e9 recouverts d\u2019une couche protectrice de mat\u00e9riau granulaire. Cette couche de confinement garantit la conformit\u00e9 environnementale de l\u2019installation ; elle emp\u00eache la migration des contaminants vers le sol et le bassin versant environnants.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t\t\t\t\t\t

Une digue ext\u00e9rieure, con\u00e7ue sp\u00e9cifiquement pour cet usage, a \u00e9t\u00e9 construite autour du bassin afin de servir \u00e0 la fois de barri\u00e8re de confinement et de support stable pour la cl\u00f4ture p\u00e9riph\u00e9rique en grillage. La digue a \u00e9t\u00e9 model\u00e9e, compact\u00e9e et finie pour offrir aux \u00e9quipes une surface propre et plane facilitant la pose des poteaux ; un d\u00e9tail qui s\u2019av\u00e8re crucial pour l\u2019alignement durable de la cl\u00f4ture.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Des projets comme le site de disposition des neiges us\u00e9es de Stanstead d\u00e9montrent toute l\u2019importance de faire appel \u00e0 un entrepreneur en g\u00e9nie civil exp\u00e9riment\u00e9 pour la r\u00e9alisation d\u2019infrastructures publiques. Chaque \u00e9tape du projet, de l\u2019essouchement initial jusqu\u2019\u00e0 l\u2019installation des derni\u00e8res sections de cl\u00f4ture, doit \u00eatre soigneusement coordonn\u00e9e afin d\u2019assurer la performance et la durabilit\u00e9 de l\u2019ensemble des ouvrages.<\/span><\/p>

Pr\u00e9fontaine & Associ\u00e9s a livr\u00e9 une installation con\u00e7ue pour r\u00e9pondre aux besoins de la municipalit\u00e9 pendant de nombreuses ann\u00e9es.

L\u2019ensemble des travaux a \u00e9t\u00e9 r\u00e9alis\u00e9 dans un \u00e9ch\u00e9ancier serr\u00e9, tout en respectant scrupuleusement les exigences en mati\u00e8re de sant\u00e9 et s\u00e9curit\u00e9 au travail, les normes environnementales applicables ainsi que les plus hauts standards de qualit\u00e9. Gr\u00e2ce \u00e0 l\u2019expertise de notre \u00e9quipe et \u00e0 une gestion efficace du chantier, le projet a \u00e9t\u00e9 livr\u00e9 conform\u00e9ment aux attentes du client, aux exigences contractuelles et aux objectifs de performance \u00e9tablis.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
