Aquamarine Park is a water resort located on Serangan Island, South Denpasar, Bali. The function of this area is as a place of recreation, conservation, and education of marine biota. This water resort has total area of 5,7 Ha, one of the main building is marine aquarium with 4726 m2 area. This building consists of 3 floors containing marine aquarium, conservation ponds of biota marine, and water tanks. <br /> <br /> <br /> <br /> Final project focused on designing the foundation of the building and soil improvement. Idealization of soil profile around the site shows there are 2 main layers of land. First is loose sand layer at the top, then clay layer with type varies between soft clay and medium stiff clay located below of the top soil. That conditions may generate liquefaction potential for the sand layer and consolidated the soft clay layer. The soil improvement used to overcome this is by using a combination of Preloading with Prefabricated Vertical Drain (PVD). Preloading is constucted by loading a load of heavily equivalent structures on it, it aims to keep the elevation according to plan at the end of consolidation. Then PVD is installed to speed up the consolidation process on clay soil. This soil improvement also increases the soil shear strength parameter. <br /> <br /> <br /> The type of foundation used in the aquarium building structure is bored pile foundation with a diameter of 0.8 m. Bored pile is designed to reach a hard soil depth with a span of 20-22 m. The asymmetric shape of the building causes the magnitude of the torque load and lateral force that work on the foudation is high, for which it is planned to configure 9 piles in a pile group.
