The execution of soil investigation mainly contains two parts: field exploration and laboratory testing.

The minimum diameter of the boreholes will be 100 mm when undisturbed samples are scheduled to be taken. Every effort should be made to locate and record the datum elevation at which any change in stratification occurs. Work Procedure3.1 Soil Boring Soil borings are made to determine the thickness, texture and order of occurrence of the soil strata as they exist in the ground.

OD split-barrel sampler, a 3-in. Borings shall be the following type and sizes: uncased borings of sufficient size to accommodate a 2-in. Each sample as it is removed from the ground should be packed so that it will reach the laboratory (or place of storage) in the condition without loss of water or damage by freezing, heating, breakage of containers or other disturbances in transit.

The dimensions of the sampler shall conform to those shown in the Method for Penetration Test and Split-Barrel Sampling of Soils, ASTM Designation D1586, the latest revision. A sample shall always be taken in the first 1.5 meters of each boring.3.2.1 Sampler The sampler shall be a two -inch outside diameter split-barrel sampler, with an inside diameter of one and three-eighth (1-3/8) inches. The walls of uncased borings shall be adequately supported by a suitable suspension of drilling mud.Standard Penetration Test and Sampling Standard Penetration Tests shall be conducted at every change of strata and within a continuous stratum at intervals not exceeding 1.5 meters.

The record shall clearly show the number of blows for each six inches of penetration. Shall be counted and recorded. The number of blows required to drive the sampler each six inches for a total depth of 18 in. The hammer or ram used to drive the two -inch outside diameter sampler shall weigh 140Pounds and shall fall freely through a height of 30 -in.

The project identification and date of sampling shall be clearly shown on the label. The jar shall be properly labeled as to boring number, depth of sample, number of sample, and number of blows for each six inches of penetration, or as otherwise stipulated above. The containers shall be securely sealed to prevent evaporation of the soil moisture. The depth of the change shall be recorded.
