Site Investigation | Research to Balance Safety and Cost in Subdivided Built Homes on Embankment Areas

Ideal for subdivided built-for-sale houses on filled land! By using SDS testing and our unique analysis criteria, we reduce excessive ground reinforcement while preventing settlement risks.

When constructing subdivided built-for-sale houses on embankment land, the balance between the risk of differential settlement due to uneven compaction of the fill and the high costs of ground reinforcement driven by fear of that risk becomes a significant challenge. The ground investigation solution proposed by Geotech utilizes unique high-precision technology and a vast database to maximize both safety and cost-effectiveness. The investigation employs the SDS (Screw Driver Sounding) test, which can automatically identify soil types and accurately capture the characteristics of cohesive and granular soils through torque measurement. In terms of analysis, in addition to regulatory standards, a unique criterion evaluating "strength, shrinkage, and deformation" based on three items and eight elements is applied. By combining settlement simulations that cover stress propagation at depths of 2m and 5m with evaluations of the years since the embankment was created, we derive an "optimal foundation design" that eliminates excessive columnar improvements and pile work. By issuing ground assessment reports based on objective and reliable evidence, we strongly support the cost optimization and long-term safety assurance of the subdivided built-for-sale housing business.
