Site Investigation | Deep Soil Bearing Capacity Assessment to Facilitate Structural Review of Data Center Construction
Boring survey
To facilitate the structural suitability assessment of data centers, establish clear evidence of bearing capacity through deep boring and viscous soil consolidation analysis.
In the new construction project of a data center, the smooth and reliable passage of building confirmation applications and structural conformity assessments is an extremely important issue from the perspective of adhering to the project schedule and controlling development costs. GeoTech's dedicated ground investigation service rigorously obtains data on the depth and continuity of the supporting layers present in the deep strata through deep borehole surveys and standard penetration tests. Furthermore, by conducting laboratory consolidation tests using undisturbed samples from alluvial clay layers, we establish a solid objective basis for long-term consolidation settlement simulations, which are strictly required by third-party review organizations, by accurately determining physical constants such as consolidation yield stress and compression index. In addition, by visualizing the ground deformation coefficient through in-situ horizontal loading tests and conducting multifaceted stratum verification using our proprietary database "GEODAS," we create detailed ground analysis reports that do not generate points of concern or technical inquiries during the review process. We strongly support the elimination of unnecessary delays in the review process, ensuring reliable approval acquisition and shortening the construction schedule.

basic information
We will conduct drilling using a deep boring machine and perform standard penetration tests (continuous N-value measurement) in accordance with JIS standards. Undisturbed samples will be collected from the cohesive soil layer using a triple tube sampler, and the consolidation yield stress, compression index, and overconsolidation ratio will be accurately determined through the JIS A 1217 staged loading consolidation test. Additionally, the lateral deformation coefficient (E value) of the ground will be directly measured in the field through in-situ lateral loading tests (LLT). All data will be integrated with our in-house ground information system GEODAS and delivered as an advanced analysis report for review and structural assessment.

Applications/Examples of results
It is ideal for obtaining data for building confirmation applications and structural conformity assessments in new construction and expansion plans for data centers and large-scale IT infrastructure facilities. It can be used as clear measured evidence in vertical and horizontal load calculations conducted by structural designers, as well as in structural checks of long-term settlement considering over-consolidation ratios. Additionally, it can be widely utilized for rapid response preparation to advanced technical verifications from third-party review organizations, facilitating foundation design change procedures under complex geological conditions, and avoiding delays in the overall project's commencement.
