Site Investigation | Optimization of Foundation Costs for Custom Homes to Prevent Excessive Improvement on Weak Ground
An optimization method that prevents excessive improvement through soil quality assessment and soil strength evaluation using the SDS test, significantly reducing foundation costs while maintaining the safety of custom-built homes.
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.
