Ground Investigation | Early Identification of Ground Risks and LCC Optimization in Data Center Development
Ground investigation
Early identification of ground risks in data center development, optimizing lifecycle costs through deep boring and viscous soil consolidation analysis.
To successfully lead a large-scale data center development project, it is essential to fully identify ground risks in the early planning stages and optimize the life cycle cost (LCC) with a long-term operational perspective. Geotech's specialized ground investigation services precisely measure the depth, continuity, and layer thickness variations of deep supporting layers through deep boring surveys and standard penetration tests, ensuring that budget overruns and schedule delays due to misestimations in the early development stages are effectively prevented. Furthermore, by conducting indoor loading consolidation tests using undisturbed samples from alluvial clay layers, we accurately identify consolidation yield stress and compression indices to clarify future settlement behavior, thereby preventing the occurrence of substantial equipment renovation costs and repair expenses after facility operation. Additionally, by measuring the ground deformation coefficient through in-situ lateral loading tests (LLT) and utilizing our proprietary database "GEODAS" for multifaceted stratigraphic analysis, we ensure safety while eliminating unnecessary excessive foundation construction costs. We strongly support the reduction of business investment risks and the maximization of project profitability with reliable ground consulting technology.

basic information
We will adopt a boring machine suitable for deep excavation and standard penetration tests (N-value measurement) in accordance with JIS standards as the basic method. In cohesive soil layers, we will conduct undisturbed sample collection and measure various parameters such as consolidation yield stress Pc, compression index Cc, and consolidation coefficient Cv through the JIS A 1217 staged loading consolidation test. Furthermore, we will measure the lateral deformation coefficient of the ground in situ using in-hole lateral loading tests (LLT). The obtained data will be corrected and analyzed using our in-house ground information system GEODAS and submitted as a clearly substantiated technical report that eliminates excessive investment.

Applications/Examples of results
It is ideal for comprehensive ground risk assessment during the site selection and basic design phases of large-scale data centers and hyperscale DC development. It can be used to completely eliminate uncertainties related to deep support layers, reduce long-term maintenance costs (LCC) through settlement simulations, and avoid excessive piling work and ground improvement. Additionally, it can be utilized as a solution for developers and structural designers to quantify investment risks during business planning, provide high-precision evidence in review and structural conformity assessments, and optimize construction costs.
