In housing reconstruction plans on sites of existing building demolitions or historically significant residential land, issues frequently arise due to the presence of leftover concrete debris, remnants of old foundations, and uneven backfill soil, which make it difficult to accurately determine the ground bearing capacity. Insufficient preemptive measures for obstacles can lead to construction delays after work has begun and unexpected additional costs for ground reinforcement, resulting in disputes and distrust with the client. This document details a "Ground Assessment System for Demolition Sites" that uses robust crushing and penetration of buried obstacle layers to measure the true deep support layer, thereby stopping excessive reinforcement. Utilizing GeoTech's high-penetration impact mechanism and multi-point measurement technology, we accurately visualize the deep soil bearing capacity directly beneath the foundation without being affected by surface debris. By capturing the uneven ground structure of areas like basement remnants in three dimensions, we derive the optimal foundation type (flat foundation, partial reinforcement, various piling methods) that eliminates unnecessary piling work. We provide convincing explanations to clients through objective data that combines numerical values and diagrams, strongly supporting the improvement of contract rates and profit margins.

In the construction plan for a steel frame building on a small site in an urban area with densely packed adjacent buildings, restrictions on the delivery of large boring machines and the narrow frontage with neighboring properties pose significant challenges to obtaining accurate ground data. This document explains a smart foundation explanation technique utilizing "self-propelled ram sounding surveys" that measures continuous ground data up to a depth of 30 meters using a self-propelled compact machine with a total width of 830 mm, optimizing the length of steel pipe piles. GeoTech's fully automated measurement system breaks through hard strata with powerful penetration capability from an automatic drop hammer, extracting high-precision data that has a strong correlation with standard penetration test N values through continuous Nd value data and torque correction processing. By measuring multiple points within the site, the inclination of the bearing layer and localized uneven ground are visualized in three dimensions, thoroughly eliminating excessive pile length designs and unnecessary impact construction. By presenting clear structural justifications, we facilitate the building confirmation review and structural conformity assessment, strongly assisting in optimizing construction costs and ensuring high accountability to project owners and clients.

In the construction plan for single-story logistics warehouses, the designation of expensive deep pile foundations or columnar improvements due to the underestimation of safety factors is a significant issue that severely pressures construction costs. This document explains a smart foundation explanation technique using "plate load tests" to measure the true bearing capacity of the shallow ground directly beneath the foundation and eliminate excessive ground reinforcement work. Geotech's plate load tests directly measure the ultimate bearing capacity and deformation coefficients at the actual pressure surface level, scientifically supporting design changes to direct foundations such as slab foundations. High-precision settlement simulations based on staged loading data prevent the risk of unevenness and settlement of the floor slab associated with forklift operations and the installation of high-rise racks. Furthermore, the eco-foundation proposal, which minimizes the generation of excavation spoil, also contributes to CO2 emission reduction. By presenting clear technical evidence, we fulfill the requirements for structural compatibility assessment and accountability to clients, strongly supporting significant cost reductions and shortened construction periods. We encourage you to utilize this document to achieve a highly satisfactory optimal foundation design.

In residential planning for sites with varying elevations, such as embankment construction areas or terraced subdivisions, addressing differential settlement caused by variations in ground strength (cut-and-fill transitions) and the presence of subsiding layers near the surface is the most critical issue. However, excessively imposing costly ground reinforcement work due to fear of risk can unjustly inflate construction costs and become a major factor leading to dissatisfaction and distrust from clients. This document explains the "smart explanation technique" to prevent excessive reinforcement in uneven embankment sites and to select and explain foundation specifications based on evidence. Geo-tech's ground surveys combine penetration data from multiple points with elevation measurements to three-dimensionally clarify the position of cut-and-fill boundaries and the thickness of subsiding layers. With a unique "three-item, eight-factor" evaluation criterion and an annual analysis record of 100,000 cases, we accurately determine the safe range for direct foundations such as slab foundations. By utilizing a visually represented evaluation report, we can clearly explain the validity of the construction to clients, achieving high trust and smooth contract agreements.

This service identifies the specific ground risks associated with demolition sites and supports the safety of buildings and the preservation of asset value. 【Usage Scenarios】 - New development on sites of demolished wooden apartments - Evaluation of differential settlement risks due to ground unevenness - Risk assessment before purchasing development land 【Benefits of Implementation】 - Early detection of differential settlement risks and planning of countermeasures - Improvement of structural safety of buildings - Maintenance and enhancement of asset value

This solution is a proposal for ground evaluation and method selection that avoids excessive reinforcement work in embankment construction sites and soft ground, optimizing the foundation costs for custom-built homes. It precisely analyzes the thickness of the embankment and backfill, the number of years since construction, and the compaction state to objectively assess future settlement and shrinkage risks. Even when reinforcement is necessary, it does not rely solely on uniform columnar improvements but suggests the best plan suitable for the site's soil quality and depth from options such as surface improvement, columnar improvement, pure piles, steel pipe piles, and eco-friendly methods. By incorporating eco-design to reduce soil disposal and waste disposal costs, the ground guarantee review is smoothly passed with annual analysis performance data of 100,000 cases and advanced considerations by qualified personnel. This achieves both improved project profit margins and high construction quality simultaneously. For businesses struggling with ground assessment in embankment construction sites, we provide evidence-based cost reduction and reliable ground measures. Furthermore, the evaluation results are presented in an easy-to-understand graphical report, making the explanation of safety to potential buyers clear and serving as an effective sales tool to enhance their sense of security and understanding.

This technical proposal is a ground investigation and analysis solution that prevents excessive ground improvement work in soft ground and optimizes the foundation costs of custom homes. By digitally measuring soil conditions that were difficult to distinguish with conventional simple sounding tests using the SDS test, we objectively identify sandy soils, clayey soils, loam, and humus based on rotational torque and penetration resistance. Furthermore, by combining depth-specific stress propagation analysis of building loads with our unique judgment criteria based on an annual track record of 100,000 cases, we accurately evaluate the inherent bearing capacity of the ground (allowable bearing capacity). This approach avoids uniform deep improvement and excessive pile work, maximizing the potential for direct foundations such as slab foundations and strip foundations. Additionally, clear reports that visualize subsurface cross-sections and settlement predictions facilitate technical explanations to clients and streamline consensus building. Through appropriate design based on evidence-based technical data, we contribute to significant reductions in construction costs and improvements in builders' gross profit margins, while also smoothly addressing the review of ground warranty systems, strongly supporting the creation of safe and secure homes.
