A large building is to be built on a thick layer of normally consolidated clay shown in the figure below. The building is to be placed at the bottom of a 4 m deep excavation, which will correspond to 1 level of parking garages. The water table remains 4 m below the ground surface during the entire process. Find the OCR in the middle of the clay layer at Point A, a long time after excavation and before construction of the building. (Answer tolerance = 2%).
