Current World Record O-cell Tests

The image at left is an artist's rendering of the New Mississippi River Bridge in St. Louis, Missouri, scheduled for completion in 2014. The bottom-up static load test, performed June 2010, applied over 321MN (bi-directional) to the pile, resulting in about 4mm of upward movement of the shaft and about the same magnitude of downward displacement at the base. The rock socket was about 7m deep and 3350mm diameter in very hard limestone. Four 870mm O-cells placed at the base of the shaft were loaded to 150% of their rated capacity to achieve the record load.
2005 WORLD RECORD 279 MN (31,350 TON) LOAD TEST
In March 2005, a new world record for deep foundation load testing of 279 MN was set in Incheon, Korea on the Incheon 2nd Link Bridge - Causeway project. This mega-structure links the new Incheon International Airport with the new Songdo City, over 10 km away. This test exceeded Loadtest's 2003 world record by 114 MN.
LOADTEST conducted the record setting load test utilizing five (5) 870 mm diameter 60 MN capacity O-cells on a single plane in the 3m diameter pile. The general contractor for the project was AMEC and the foundation contractor was Samsung.
