The “Chambre de commerce” building in Tripoli consists of a 12 storey concrete building with 3 basements. The lot is surrounded by residential building from one side, an empty lot at the opposite side and by major roads on the other two sides. The topsoil layer (about 4m) consists of clay & silty sand material, then the clay becomes silty with gravel down to 12m. Below 12m the soil becomes silty sand with gravel. The excavation needed for the new building was about 7m deep Int’l I.G.M. proposed and constructed an anchor/pile system on the building & roads sides to retain the excavated side and minimize any movement of the adjacent structure or infrastructures. The piles were 60cm in diameter with 1.6m spacing c/c and one or two rows of active anchors tensioned against a concrete waler beam.
