Evaluation of Uneven Load and Optimal Foundation for Factory Energy Storage Containers for Semiconductor Factories
Evaluation and optimization of uneven load settlement affecting precision equipment installation through plate load testing.
In semiconductor factories, the stability of the ground at the installation site is required for the stable operation of precision equipment. Container-type storage batteries installed within the factory premises are prone to uneven loading due to the non-uniform arrangement of internal equipment, which can lead to localized ground subsidence and equipment tilting. This may affect the performance of precision instruments. The ground bearing capacity evaluation solution provided by Geotech accurately measures the original allowable bearing capacity and ground reaction coefficient of shallow ground by conducting plate load tests at the actual foundation pressure surface level. Simple sounding surveys visualize ground strength, which tends to be biased towards safety, as objective numerical data, allowing for a scientific determination of the feasibility of adopting optimal direct foundations while avoiding excessive deep piles or ground improvement work. With strict multi-stage loading data and settlement analysis simulations compliant with the standards of the Japanese Geotechnical Society, the review process for building confirmation applications and structural suitability assessments can also proceed smoothly. Utilizing our highly qualified staff with extensive practical experience and our proprietary database "GEODAS," we provide comprehensive support for the installation plan of storage battery containers, achieving both safety assurance and significant reductions in construction costs.

Applications/Examples of results
It is optimal for evaluating the foundation ground when installing container-type storage batteries (industrial stationary storage systems) on the premises of factories and business sites. It can be utilized for addressing uneven load issues associated with battery expansion, determining the allowable ground pressure for floor slabs and direct foundations, and pre-verifying the risk of differential settlement. Additionally, it is effective as a second opinion investigation aimed at reducing construction costs and shortening construction periods by avoiding excessive piling and deep ground improvement. It broadly supports ground diagnosis when repurposing outdoor vacant spaces or parking lots within existing factory sites, as well as submitting structural calculation evidence to designated inspection agencies, ensuring the safe construction of industrial energy facilities.
