The “Achrafieh 683” building in Achrafieh consists of an 11 stories concrete building with 3 basements. The lot is surrounded by residential buildings from two sides and by roads on the other two sides. ID Number 03-519 The topsoil layer (about 4m) consists of sand material, then hard marl. The excavation needed for the new building was about 10m deep. Due to the limited time available, Int’l I.G.M. proposed and constructed vertical micropiles system coupled with a vertical concrete wall (10cm to 20cm). In the horizontal direction, two rows of active anchors, with spacing 2 to 3m were installed to retain the excavated sides and minimize any movement of the adjacent structure or infrastructures. The Micropiles were 10cm in diameter with 0.7m to 1.2m spacing c/c.
