SWS + Hand Auger Survey to Capture Soil Quality and Improve the Accuracy of Foundation Design
This is a ground survey targeting small-scale buildings, combining hand auger boring with the Swedish Weight Sounding (SWS) test. In addition to measurements from the SWS, the soil conditions directly beneath the foundation base are actually verified. By combining soil information such as clay, sandy soil, humus soil, and loam with SWS data, the accuracy of predicting ground subsidence is significantly improved, enabling the determination of appropriate foundation specifications and the reliable design of ground reinforcement works in soft ground.

basic information
This is a specification provided by a geological survey company registered with the Minister of Land, Infrastructure, Transport and Tourism. In addition to obtaining data such as the converted N value by SWS, soil will be directly collected using a hand auger to a depth of approximately 2 meters. The survey report submitted as a deliverable will include a ground assessment report and specialized considerations by a residential ground survey chief technician. Furthermore, detailed data covering soil quality, color tone, water content ratio, and columnar diagrams at each depth will be clearly stated, ensuring high technical reliability.

Applications/Examples of results
It is used in response to the stricter building confirmation review due to the revision of the Building Standards Act, as well as for determining the foundation specifications of small-scale buildings and designing ground reinforcement work. As an example of achievements, during ground surveys for single-family house construction, the presence of fill up to GL-0.8m, the composition of the loam and clay layers beneath it, and the water content ratio (135%, 60%, etc.) were accurately identified, and based on the assessment of stable ground trends, optimal direct foundation specifications such as slab foundations were determined.
