UNIVERSITE LA SAGESSE

Client: ST. PAUL DE LA SAGESSE UNIVERSITY

The UNIVERSITE St. PAUL DE LA SAGESSE project is a new University to be built in the Tehouita area. The area of the project is about 7000 m2. The excavation will extend down to 10m below the street level. Hence, a retaining system is necessary to achieve this excavation. The soil is a sandy clay. On one side of the site the top soil (4m) is a gravelly river deposit. I.G.M. proposed a solution optimized by sloping the top 4 meters. The shoring system consists of a 15cm shotcrete wall retained by 2 rows of nails. The length of The Nails is 11m. Where the top gravelly layer was encountered, nails driven by percussive hammer were added
