Ground investigation | Ground investigation to identify the support layer in a narrow steel building with delivery restrictions.

Ideal for constructing steel frame buildings in narrow urban areas where large machinery cannot enter! The ram sounding test automatically measures the depth of the supporting layer with high precision.

In urban areas with limited space for construction, there is a challenge where large boring machines cannot access the site due to restrictions on the site frontage and the front road. The automatic ram-sounding test provided by Geotech uses an ultra-compact self-propelled machine with a total width of only 830 mm, allowing for smooth delivery and installation even in densely packed site environments. With a fully automated striking mechanism using a 63.5 kg hammer, it can penetrate hard layers with an N value exceeding 30 and gravel layers that are impossible to penetrate with conventional SWS tests, enabling investigations up to a depth of around 30 m. Additionally, by automatically measuring the number of strikes and rotational torque simultaneously for every 200 mm of penetration, it reliably corrects for the effects of surrounding friction resistance, producing reliable ground data that has a high correlation with the N value from standard penetration tests. This minimizes the setup effort and investigation period of the equipment, allowing for low-cost and rapid confirmation of reaching a reliable bearing layer, thus significantly streamlining the design and construction process of safe pile foundations for steel frame buildings in urban areas with limited space.

Ground investigation | Ground investigation to identify the supporting layer in a narrow steel building with delivery restrictions.

Prevent excessive pile length design in narrow steel frame buildings! Accurately determine the depth of deep supporting layers with automatic continuous penetration tests using ultra-compact machines.

In mid-rise steel buildings planned on small plots, there are often cases where unnecessary long piles are designed due to excessive safety factor estimates and ambiguous ground data, leading to skyrocketing construction costs. GeoTech's "Automatic Ram Sounding Test" utilizes an ultra-compact self-propelled crawler machine with a width of just 830 mm, enabling high-precision deep investigations even under construction conditions where large machinery cannot enter. The automatic striking mechanism allows for the crushing and excavation of hard layers with an N value exceeding 30, which is difficult in SWS tests, and collects continuous ground resistance data up to a depth of 30 meters. Additionally, by electronically measuring the penetration strike count and simultaneously measuring the rotational torque, the influence of side friction resistance is accurately and automatically eliminated, allowing for the precise derivation of only the tip resistance that strongly correlates with the N value of standard penetration tests. The results are instantly visualized as digital data, improving the accuracy of structural calculations and foundation design. By optimizing pile lengths based on clear numerical evidence, significant reductions in pile construction costs and budget optimization are achieved while maintaining safety and robustness.

Ground investigation | Ground investigation to confirm the bearing layer in a narrow steel building with transportation restrictions.

Perfect for alternatives to boring! We reliably confirm deep support layers through automatic ram sounding tests in steel frame buildings with limited access on narrow sites.

When constructing a steel frame building on a small site in an urban area, traditional boring standard penetration tests often face challenges such as securing installation space, high investigation costs, and long temporary periods, making their implementation difficult in many cases. GeoTech's "Automatic Ram Sounding Test" utilizes a super compact self-propelled crawler machine with a width of only 830 mm, allowing for easy self-propelled entry and setup even in sites with limited access routes and working space. Equipped with a fully automatic striking mechanism using a 63.5 kg hammer, it can penetrate hard layers with an N value exceeding 30, which cannot be reached by SWS tests, allowing for excavation up to around 30 meters deep. By measuring the number of strikes and simultaneously measuring the rotational torque to accurately correct for the effects of surface friction, it calculates highly precise ground strength data with correlation equivalent to that of boring tests. The use of dry construction without water and the reduction of the need for large scaffolding assembly minimizes the effort for temporary setup and removal, enabling verification of the bearing layer with overwhelming short construction periods and low costs compared to boring investigations. This effectively mitigates delays in the construction process and budget overruns for steel frame buildings in small urban sites.

Site Investigation | High-Precision Support Layer Penetration Survey Supporting Structural Calculations for Small-Site Steel Buildings

A ram sounding survey to accurately obtain deep support layer data essential for structural calculations in a narrow steel building where large heavy machinery is not permitted.

In the construction of steel frame buildings on small plots in urban areas, accurately understanding the bearing layer is essential for designing foundations that can withstand high loads; however, the limitations of large boring machines pose a technical obstacle. This service employs a small crawler-type automatic ram sounding testing machine, providing a solution to complete high-precision deep bearing layer investigations even in densely populated urban areas. The fully automatic striking device allows a 63.5 kg hammer to free fall from 500 mm, automatically recording the Nd value for every 200 mm penetration, thereby continuously visualizing the bearing layer equivalent to an N value of 50 and the stratigraphic composition up to a maximum depth of 30 m. By applying friction correction through torque measurement, we provide high-precision data that can be directly compared to the N values from standard penetration tests, ensuring robust ground evidence necessary for structural calculations. Continuous measurements at multiple locations capture the inclination and thickness variations of the bearing layer, enabling the design of optimal pile lengths on a unit basis, achieving safe and economical foundation quality, and guaranteeing the long-term safety of the building.

Site Investigation | Research to Balance Safety and Cost in Landfill Development for Pre-Sold Houses

Eliminate excessive ground improvement that pressures profit margins in the sale of residential houses on filled land to zero. An optimal foundation design solution that accurately assesses settlement risks.

In developed embankment areas on hilly or sloped land in urban suburbs, the unevenness of ground compaction raises concerns about the risk of differential settlement in subdivided built homes. As a result, excessive ground reinforcement work, based on an unnecessarily high safety factor, has become the norm, putting pressure on builders' profits. Geotech provides ground investigation services that accurately assess the unique risks of embankment areas and support "optimal foundation design" to prevent excessive reinforcement. Our analysis goes beyond mere N-value measurements to comprehensively evaluate shrinkage risks based on the years of embankment construction and thickness, as well as the consolidation settlement characteristics of different soil types. Based on data from multiple points, we calculate the maximum settlement within the site and the deformation angle (tilt) of the building, comparing these with the standards set by regulations (such as the presence or absence of self-settlement layers at 2m and 5m below the foundation). By calculating precise allowable stress considering load distribution according to depth, we minimize the scale of reinforcement work without compromising safety, achieving a rational foundation design that directly improves the cost performance of the built home business.

Site Investigation | Visualization Survey of Ground Bearing Capacity to Optimize Pile Layout for New Building Construction on Soft Ground

3D visualization of ground bearing capacity for new building construction on weak ground! It simultaneously achieves the maintenance of structural safety and optimization of construction costs by preventing excessive piling.

This technical solution is a high-level ground investigation service aimed at new construction plans for mid-rise and heavy-load buildings on soft ground, optimizing pile layout and foundation structure by visualizing ground bearing capacity from multiple perspectives. In construction sites where uneven soft layers or complex inclined supporting layers exist, relying solely on conventional single-point investigations for design can lead to excessive design, overestimating pile lengths and numbers to avoid settlement risks. Geotech conducts high-precision N-value acquisition through standard penetration tests and multi-point integrated analysis of deep penetration data, accurately visualizing the long-term and short-term allowable vertical bearing capacity of the ground and layer thickness changes in 3D images. By directly linking the obtained structural strength parameters to the architectural structural calculation model, it is possible to accurately determine the optimal pile layout and shortest pile length according to the actual load under each column. This eliminates unnecessary pile driving work and head cutting processes at the construction site, significantly reducing overall construction costs and timelines while perfectly ensuring structural safety. Furthermore, our qualified specialists prepare judgment documents that clearly outline the basis for analysis, allowing for a swift progression of structural conformity assessments and building confirmation reviews.

Site Investigation | Optimize Pile Layout for New Buildings on Soft Ground! Detailed Ground Bearing Capacity Evaluation Survey

Clarifying settlement behavior in new building construction on soft, cohesive soil! Achieving a high level of both pile placement and structural safety through precise visualization of ground bearing capacity to prevent differential settlement.

This technical solution is a ground consulting service that eliminates the risk of uneven settlement, which is likely to occur in new building construction plans on soft, cohesive ground. It ensures the long-term safety of buildings through precise evaluation of ground bearing capacity and optimization of pile placement. In sites where alluvial clay and soft soil layers are deeply distributed, concerns arise about uneven slopes and structural cracks due to eccentric loads from superstructures and long-term consolidation settlement. Geotech combines standard penetration tests, laboratory soil tests, and multi-point ground bearing capacity measurements to accurately visualize the consolidation yield stress and deformation angles of cohesive soils through numerical simulations. By linking the obtained quantitative data with the axial and lateral forces under the columns of the superstructure, we establish an optimal pile placement design that focuses on areas with high settlement risk. This prevents excessive piling due to overly conservative safety factor estimates while providing reliable ground evidence that smoothly passes rigorous structural compatibility assessments and building confirmation reviews. We support the asset value and preservation of buildings throughout their lifecycle.

Site Investigation | Precision Ground Bearing Capacity Visualization Survey to Optimize Pile Layout for New Construction on Narrow Lots

Visualizing continuous ground bearing capacity in the construction of new buildings on narrow plots with moving-in restrictions! By conducting space-saving high-precision surveys, we prevent excessive pile length design and optimize pile placement.

This technical solution is a high-precision ground investigation service aimed at new building sites in urban areas where large machinery cannot easily access. It visualizes soil bearing capacity and optimizes pile placement through space-saving automatic continuous measurement. In densely populated urban areas or construction sites facing narrow streets, it has been difficult to set up conventional large boring machines, often leading to designs that assume excessive safety factors without obtaining sufficient data on the supporting layers, resulting in overly long and numerous piles. GeoTech employs a compact self-propelled automatic penetration device, approximately 830mm wide, allowing for smooth equipment transport even in tight spaces, and automatically obtains Nd values and rotational torque up to a maximum depth of 30m with high precision in 200mm increments. By clearly capturing the inclination of supporting layers and changes in soil bearing capacity from continuous data collected at multiple points within the site, we derive a rational pile placement design that eliminates unnecessary pile driving and excessive lengths, in conjunction with structural calculations. The speedy investigation procedure, which eliminates mud water treatment and large-scale temporary works on site, contributes to significant reductions in construction time and costs while considering the surrounding environment.

Visualizing 3D ground bearing capacity for new building construction on complex ground! By suggesting optimal pile placement, we ensure structural safety while reducing unnecessary construction costs.

This solution is a high-precision ground consulting service aimed at new building construction plans in complex urban multi-layered ground and redevelopment areas. It visualizes ground bearing capacity in three dimensions to optimize pile placement and foundation design. In sites where embankments, alluvial clay layers, and sandy soil layers are intricately intertwined, traditional point investigations often fail to adequately assess local height differences and variations in ground bearing capacity, leading to unnecessary pile driving or excessive safety factor estimates to prevent unexpected settlement. Geotech integrates and analyzes extensive ground database GEODAS, multi-point continuous penetration tests, and detailed soil mechanics test data to accurately visualize the three-dimensional ground bearing capacity structure of the entire site. By directly linking the obtained continuous parameters to the axial and lateral forces in structural calculation models, it calculates the optimal pile placement and the minimum necessary accurate pile lengths according to load concentration areas. This significantly reduces unnecessary excessive piling work and material costs while providing reliable evidence that swiftly clears structural conformity assessments and application approvals, strongly guiding the project to success.

Site Investigation | Visualization Survey of Bearing Capacity to Optimize Pile Layout for New Building Construction on Soft Ground

Visualizing horizontal load capacity in new building construction on weak ground! By analyzing ground reaction forces, we prevent excessive pile diameter and reinforcement, achieving optimal pile placement.

This solution is a ground consulting service that accurately visualizes the horizontal bearing capacity and lateral ground reaction coefficient during earthquakes in building construction plans on soft ground, optimizing pile layout and foundation structure. In sites where thick soft layers are distributed, there has been a challenge of selecting excessively thick pile diameters and excessive pile driving to suppress the bending moment at the pile head and horizontal displacement during earthquakes. 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.
