Site Investigation | Optimization Method for Housing Foundation Costs to Prevent Excessive Improvement of Embankments and Weak Ground
A solution that prevents excessive improvements by evaluating the number of years since the land was filled and selecting the optimal reinforcement method, thereby balancing the safety of custom-built homes with the reduction of foundation costs.
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.
basic information
The applicable targets are planned sites for single-family custom homes and subdivided residential properties. The survey and evaluation methods available include SWS testing, SDS testing, embankment age assessment, soil automatic classification, and wide-area ground database (GEODAS) matching. The scope of reinforcement proposals includes surface ground improvement (GL-0.5 to 2m), columnar improvement (GL-1.5 to 8m), pure piles (GL-1.5 to 10m), and small-diameter steel pipe piles (GL-2 to 20m). As deliverables, we will issue detailed ground assessment reports, comparative studies of reinforcement methods, and eco-foundation design proposals.

Applications/Examples of results
It is widely used for cost reduction of excessive reinforcement in new construction plans for custom-built and developer-built homes on filled land and soft ground, as well as for selecting and reviewing optimal ground reinforcement methods. It is ideal for reducing the generation of surplus soil and disposal costs associated with ground improvement work, verifying the feasibility of changing to direct foundations through second opinion diagnostics, and smoothly confirming compliance with major ground guarantee systems and housing performance display systems. Additionally, it can be effectively utilized for compressing total construction costs and improving gross profit margins in single-family housing development projects and custom home construction, as well as for appealing safety to potential buyers.
