At a newly constructed school in Phuket, which consists of two building blocks, it was suspected that the strength of both the 1stfloor and the 2ndfloor precast slabs was not sufficient as it may have been shown in the design. Thus, a load test was requested to determine whether the structure was safe given the current load condition. Three slab panels were selected for the test. Panel 1 was located on the 1st floor of Building Block 2 while Panels 2 and 3 were on the 2ndfloor of Building Block 1. Water ponding was used as the applied load with the maximum of 560 kg/m2.
