In the architecture of data centers that support a highly information-oriented society, a vast number of heavy server racks and uninterruptible power supplies are concentrated, resulting in ground pressures that far exceed those of typical buildings. If there are uneven layers of viscous soil or weak layers in the deep ground, minor yet serious differential settlement may occur after the facility begins operation, posing risks of equipment malfunction and structural damage. Geotechnical ground investigations clarify the properties of deep supporting layers through deep drilling and standard penetration tests. Furthermore, by conducting laboratory consolidation tests using undisturbed samples to identify consolidation yield stress and compression index, we can highly simulate future settlement amounts and convergence behavior. Additionally, by calculating deformation coefficients through in-situ horizontal loading tests and combining them with comparisons of surrounding ground using the database "GEODAS," we present a clearly substantiated long-term allowable bearing capacity. This helps prevent facility accidents and ensures robust structural safety.

This technology is an eco-ground measurement service that avoids excessive ground reinforcement in uneven ground at the site of demolished wooden apartments, achieving the suppression of drilling residual soil generation and reducing environmental impact. In sites after demolition work, high-cost pile construction or deep improvement is often selected uniformly across all points due to localized soft layers, resulting in a significant amount of industrial waste soil. This measurement method precisely identifies ground bearing capacity and soil classification using multi-point screw weight penetration tests (SWS tests) and optional SDS tests. It reflects the ground propagation characteristics of building loads (reduction effects at 2 meters and 2-5 meters below the foundation) in the analysis, leading to pinpoint reinforcement design limited to truly necessary locations and depths. This significantly reduces disposal costs for drilling residual soil and CO2 emissions associated with transportation, promoting environmentally conscious construction (ESG/SDGs). While ensuring high-level safety in uneven ground, it dramatically shortens and reduces construction costs, maximizing profitability for business owners.

This technology is a ground investigation method that precisely identifies the risk of settlement caused by uneven ground due to cut and fill in the demolition site of wooden apartments with elevation differences and terraced history. In ground conditions where hard cut soil and soft fill soil coexist, known as "cut and fill crossing," there is a risk of catastrophic differential settlement occurring after new construction due to significant differences in bearing capacity. This service integrates and analyzes screw weight penetration tests (SWS tests) at multiple points with elevation survey data to three-dimensionally grasp the position of the cut and fill boundary and changes in the thickness of the fill layer. By simulating the estimated deformation angles (tilt of the building) between measurement points from the acquired continuous data, we quantify the impact of uneven settlement on the structure. Based on the analysis results, we propose targeted measures focused only on the fill areas that require reinforcement, rather than conducting uniform and costly improvement work across the entire site. We strongly support safe and secure apartment construction while eliminating potential issues with uneven ground and optimizing reinforcement costs.

This solution is a ground consulting service that highly integrates and correlates extensive ground database and multi-point field sounding measurements for building new construction plans on soft ground. In sites where uneven soft soil layers and complex undulations of bearing layers are hidden, relying solely on single-point investigations can lead to evaluation errors of the supporting ground, directly resulting in excessive designs such as unnecessary extensions of pile lengths and increases in the number of piles. Geotech immediately cross-references accumulated surrounding boring data (GEODAS) with continuous Nd values and torque data obtained on-site. This allows for the precise identification of the three-dimensional transition of ground bearing capacity and local soft spots. By directly linking the visualized ground bearing capacity values with structural calculation models, we determine the minimal pile layout and optimized pile lengths in millimeter increments according to stress concentration under columns. This prevents rework of pile head drilling and chipping at the construction site, significantly optimizing construction budgets and timelines.

This solution targets new building construction plans in demolition sites and redevelopment areas, providing high-precision ground consulting services that accurately visualize deep soil bearing capacity while eliminating the impact of underground obstacles and optimizing pile placement. In uneven fill and backfill ground mixed with old foundations and concrete debris, traditional simple surveys often fail to penetrate, leading to concerns about unexpected settlement risks and the tendency to choose overly conservative designs with excessive pile lengths and numbers due to inflated safety factors. Geotech employs a sounding test machine with high penetration capability to safely penetrate underground debris layers and obtain true bearing layer data up to a depth of 30 meters. By using automatic torque correction to negate the effects of side friction, we accurately digitize the effective N-value strength in 200mm increments. This data is directly linked to the superstructure calculation model to pinpoint the optimal pile placement and appropriate pile lengths. This approach completely prevents rework on-site and pile eccentricity issues, achieving reliable structural safety protection and construction cost reduction.

GeoTech conducts penetration measurements at multiple points and integrated analysis of ground deformation characteristics, accurately depicting the lateral ground reaction coefficient (Kh) and allowable vertical bearing capacity as numerical data for each depth. By linking the obtained ground bearing capacity parameters to the structural calculation model, we derive the minimum number of piles and optimal pile diameter and pile head reinforcement specifications according to the axial and horizontal forces under each column. This eliminates excessive design and significantly reduces construction labor and material costs while maintaining structural safety. A report with clear calculation basis also facilitates smooth structural compatibility assessment.

In the construction of subdivided built-for-sale houses on developed embankment land and sloped areas, the risks of differential settlement due to uneven ground and the associated excessive ground reinforcement costs are challenges. Geotech captures the unique ground behavior of embankment sites and provides ground surveys and analyses that balance safety and cost. Our surveys adopt a unique evaluation standard consisting of three items and eight elements: "ground strength, shrinkage, and deformation," in addition to legal standards. The SDS test, which digitally measures torque and penetration speed, enables accurate automatic identification of soil types. By analyzing the thickness of the embankment, years elapsed, compaction level, and soil settlement characteristics, we derive an "optimal foundation design" that prevents unnecessary long piles and excessive ground improvement, thereby supporting the reduction of total costs for built-for-sale houses and ensuring long-term safety. 【Usage Scenarios】 - Construction of subdivided built-for-sale houses on embankment land - Reduction of differential settlement risks - Optimization of ground reinforcement costs 【Benefits of Implementation】 - Cost reduction by preventing excessive design - Assurance of long-term building safety - Improvement of overall project profitability

In seismic reinforcement of logistics warehouses, it is essential to ensure the stability of existing buildings while considering future safety in the foundation design. Particularly in urban areas or regions with dense existing infrastructure, the limited site space can make it difficult to bring in large machinery, which may prevent adequate ground surveys from being conducted. This can lead to challenges in accurately identifying the support layer, raising concerns about excessive pile length design. GeoTech addresses this issue by combining neighborhood data analysis from its extensive ground information database "GEODAS," accumulated mainly in the metropolitan area, with precise on-site surveys using small self-propelled machines. By analyzing surrounding ground data from multiple perspectives in advance and conducting optimal sounding tests tailored to site constraints, we can accurately identify the support layer even under complex ground conditions and calculate the optimal pile length without excess or deficiency. This ensures the necessary bearing capacity for seismic reinforcement while also contributing to cost reduction. 【Usage Scenarios】 - Logistics warehouses in urban areas or regions with dense existing infrastructure - Sites with limited space where large machinery cannot be brought in - Seismic reinforcement work for existing buildings - Cases where ground conditions are complex and identifying the support layer is difficult

In urban planning and infrastructure development, there are many situations where construction of buildings or structures is required in limited spaces. Particularly in the construction of steel frame buildings on narrow lots, there are site-specific challenges such as the influence of adjacent buildings and restrictions on road widths. When it is difficult to bring in standard large boring survey machinery, accurately understanding the slope of the supporting layer becomes challenging, which may lead to excessive pile length design. Geotech's ground survey combines the analysis of neighboring data from its extensive ground information database "GEODAS," accumulated mainly in the metropolitan area, with precise on-site surveys using small self-propelled machines, to address these challenges. By analyzing surrounding boring column diagrams and N-value distributions in advance, and conducting sounding tests tailored to site constraints on-site, we can identify the depth of the supporting layer even in complex ground conditions by correlating both sets of data, thus calculating the optimal pile length without excess or deficiency. This achieves a balance between reducing material and construction costs and ensuring the necessary bearing capacity for the structure. 【Usage Scenarios】 - Construction of steel frame buildings on narrow urban lots - Sites with narrow access roads or delivery routes - Situations where the influence of adjacent buildings needs to be considered

In the construction of steel frame buildings on narrow sites, general contractors often face challenges due to the influence of adjacent buildings and restrictions on road widths, which can make it difficult to bring in large boring survey machinery. This can lead to an inability to accurately understand the slope of the supporting layer, resulting in cases of excessive pile length settings. GeoTech addresses this issue by combining the analysis of neighboring data from its extensive geotechnical information database "GEODAS," accumulated mainly in the metropolitan area, with precise on-site surveys using small self-propelled machines. By analyzing surrounding boring column diagrams and N-value distributions, we can predict the slope trends of the supporting layer. We obtain actual data through sounding tests tailored to site constraints and cross-reference both to determine the optimal pile length, even in complex ground conditions. This approach balances the reduction of material and construction costs with the necessary support strength for the structure. 【Usage Scenarios】 - Construction of steel frame buildings on narrow urban sites - Sites where the transport of large machinery is difficult - Cases with constraints due to adjacent buildings or road widths - Situations requiring accurate understanding of the slope and depth of the supporting layer 【Benefits of Implementation】 - Prevention of excessive design and optimization of pile length - Significant reduction in material and construction costs - Reliable assurance of the allowable bearing capacity required for the structure - Balancing safety and economy
