The total counterweight should be at least 10% greater than the anticipated maximum test load. Counterweight such as box or platform with heavy material such as concrete, steel, etc.The apparatus required for carrying out a plate load test are A factor of safety is applied to give the safe bearing capacity of soil. The total value of the load on the plate divided by the area of the steel plate gives the value of the ultimate bearing capacity of soil. The load-settlement curve is plotted from which the settlement and bearing capacity of the soil can be determined. The test load is gradually increased till the plate starts to settle at a rapid rate. The gauges should be placed separately at 120° or 90° respectively. The settlement corresponding to each load increment is recorded using at least two or three dial gauges with a least count of 0.02 mm. It basically consists of loading a rigid plate at the foundation level and increasing the load in arbitrary increments.
