Island. The 402 acre Artificial Island was build by engineers from 1936 to 1937 on the neighboring buena island. 300,000 tons of rock was used to build a seawall around an existing sand ball then followed by filling the interior with dredge material from the bay which was consistent of modern sand. The federal government paid for construction ask three permanent buildings which would serve as a potential future airport. Treasure island was constructed at the same time as the bay bridge and it was a project of Works Progress administration to construct this island, which was initially used to host the Golden Gate International exposition. Carnival gone big. It was busy. It was going to become an airport after the exposition but it was turned over to the navy and turned over to a military base for the next 50 ....
Constructed at that site. So this is causing bay mud that underlies island to consolidate over time and we can monitor that and as that consolidation primarily consolidation is complete, then this soil will be removed to the intended finished Floor Elevation of the new structures. [ music ] in the 1989 loma earthquake, the ground level of this island dropped by four inches. Pretty much uniform across the island. Loose sand material used to build the island, whether it gets hit by a seismic forces, the sand moves and consolidated. One of the processes to further stabilize the loose granular ground, a dynamic rate is used to densify the soil by High Frequency mechanical vibrations. The rig in the background has four hpiles that goes down through the upper 50 feet of sandy material and as they vibrate, they vibrate causing that san material to consolidate and settle so as we do ....
