Reliable ground reinforcement using the Σ-i method for commercial facilities | Geotech
The Σ-i method supports the structural safety of commercial facilities through calculations directly linked to survey data and digital management.
In large-scale buildings such as commercial facilities, accurate structural design based on ground investigation data is essential to prevent distortion of the structure and damage to walls caused by uneven settlement. Pouring the foundation while the ground strength is insufficient directly leads to operational risks for the facility. The Σ-i method utilizes the converted N values from SWS tests and dynamic cone penetration tests to calculate a reasonable allowable bearing capacity, ensuring reliable structural reinforcement. 【Application Scenarios】 - Ground reinforcement in the construction of new commercial facilities - Foundation design for large buildings aiming to reduce the risk of differential settlement - Reinforcement work under various ground conditions such as sandy soil and clayey soil 【Benefits of Implementation】 - Ensures design transparency through allowable bearing capacity calculations based on objective data - Improves construction quality reliability through digital construction data management - Reduces construction-generated soil through the rotary insertion method, minimizing environmental impact on the site

Applications/Examples of results
This construction method is optimal for small-scale buildings such as single-family homes, multi-family residences, and stores that are three stories or fewer, have a height of 13 meters or less, and a total floor area of 1,500 square meters or less (for single-story buildings, 3,000 square meters or less). It also accommodates foundation reinforcement for retaining wall structures with a height of 3.5 meters or less. Since it allows for design calculations directly linked to ground investigation data such as SWS tests, it is widely used at sites that aim for clear justification in building confirmation applications and structural calculations, as well as for rational and economical foundation reinforcement that minimizes excessive design.
