SAVINGS EYED FROM LOAD TEST

Hoping to push the envelope on design, bridge engineers in Florida have measured what they believe is a record test load applied to a drilled shaft pile. A testing firm in Gainesville, Florida recorded recently a 9 ft-dia, 127 ft long reinforced concrete test pile had successfully withstood a 12,000 ton load. The tests were performed using a relatively new device called the Osterberg Cell which is an hydraulic piston installed on the base of a pile reinforcement cage before it is lowered into a drilled shaft. The idea is to ultimately be able to work with shorter shafts and thereby create considerable savings. Some consider the test flawed because loading is from the bottom up versus the top down.
