We achieve ground reinforcement that supports stable factory operations through reliable support capacity calculations based on survey data.
In factory facilities, high structural safety is required to prevent differential settlement of buildings due to vibrations and heavy loads from large machinery. If the foundation is laid without sufficient ground strength, it can lead to distortion of the structure and issues with the floor surface, potentially causing production line stoppages and increased repair costs. The Σ-i method supports the establishment of a stable foundation for factories through rational allowable bearing capacity calculations based on ground investigation data. 【Application Scenarios】 - Reinforcement of floor surfaces in factories installing large machinery and heavy equipment - Foundation reinforcement in areas manufacturing precision instruments that are susceptible to vibrations - Piling into reliable support layers during the construction of new factories 【Benefits of Implementation】 - Structural design based on clear technical foundations derived from investigation data - Reduction of soil displacement and cost savings through rotary insertion methods - High transparency in construction quality through digital construction data management

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 less, 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.
