The topsoil layer (about 5m deep) consists of a silty clay material CL, then the clay becomes interbedded with a hard cemented gravel layer down to 9m. Below 9m the soil becomes soft again and the water table appears at a depth of 11m. The excavation needed for the new building was about 9m deep. I.G.M. proposed and constructed an anchor/pile system on the building sides to retaing the excavated sides and minimize any movement of the adjacent structures. On the roadsides, sheetpiles with active anchors were utilized. The piles were 40cm in diameter with a 80cm spacing c/c and 2 rows of active anchors tensioned against a concrete waler beam
