Why test? The purpose of testing is to identify and characterize soil and site conditions that may present limitations for home sites or small commercial buildings. These limitations may include seasonal wetness and ponding or disturbance as a result of cutting and/or filling. Knowing the nature and scope of any limitation will aid the client in determining the costs of overcoming the limitation. How large an area needs to be tested? The test area typically consists of the envelope of the proposed building or building addition. How many samples are needed? Generally, a minimum of 2 samples are obtained and examined within the building envelope. One sample is taken at the higher elevation and one at the lower elevation. Sampling depth typically is 1 to 2 feet below the anticipated footing depth. Additional sampling may be required if the soil conditions are extremely variable or the building envelope exceeds 4000 to 5000 square feet. How is the sampling done? William R. Kreznor & Associates, Inc. conducts testing using a truck-mounted hydraulic sampling rig. The rig pushes a tube into the ground to the required depth and extracts a core sample ranging from 1 to 3 inches in diameter. Sampling may also be conducted by augering if the soil materials are hard or contain rock fragments. If the soil contains a substantial amount of rocks, is shallow to bedrock, has been disturbed by filling, or the site is inaccessible to the truck because of slope or dense woody vegetation, the soil may need to be examined from pits excavated by backhoe.
