Microelectronics fabrication facilities vibration measurement

2 buildings consisting of a 5-story building and a 2-story building were installed with sensitive machines, which fabricate the microelectronics components such as external hard drives. Those require a free-vibration condition. Thus, 70 locations of machine vibration were measured. In each location, vibration in all three axes including two horizontal directions (X, Y) and one […]

Pile integrity test

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 […]
