Ground Investigation | Uneven Ground Settlement Asset Preservation Analysis at the Site of a Demolished Wooden Apartment Building
Thoroughly analyze the settlement risk due to the uneven ground of the demolition site, firmly achieving the longevity of wooden apartments and the preservation of future asset value.
This technology is a high-precision ground diagnosis service that analyzes the risk of uneven ground settlement at the site of demolished wooden apartment buildings from multiple perspectives, ensuring the long-term structural safety and preservation of asset value of the buildings. At the site of the demolished old building, differences in the compaction of backfill soil and stratification can lead to differential settlement after new construction, posing risks of damage that can compromise asset value, such as distortion of the structure and unevenness of fittings. This method involves conducting screw weight penetration tests (SWS tests) at multiple points to precisely obtain and digitize penetration resistance values at various depths. By estimating the deformation angle (tilt of the building) from the strength differences between adjacent measurement points, we can predict the settlement behavior specific to uneven ground from multiple angles. Through rational reinforcement design based on the calculated data, we ensure the necessary load-bearing capacity for wooden apartments while preventing excessive improvements. By preemptively blocking future settlement accident risks and providing unwavering quality evidence to building owners and investors, we significantly contribute to the longevity of apartments and the maximization of business value.
basic information
This diagnostic system is based on the Swedish Weight Sounding (SWS) test and acquires high-precision penetration data in accordance with JIS A 1221 standards. It digitally records penetration loads and half rotations within a depth range of 10 meters, and precisely calculates the equivalent N values for cohesive and granular soils based on the Inada formula. Furthermore, under our internal ISO 9001 management system, qualified staff such as residential foundation engineers apply unique evaluation criteria based on three items and eight elements (strength, shrinkage, deformation, etc.). A detailed report including data on deformation angles between measurement points will be produced and bound.

Applications/Examples of results
It is utilized in situations where there is a desire to maintain long-term structural safety and asset value in newly constructed rental apartments and collective housing primarily built on the sites of demolished old wooden apartments. It is ideal for investors, clients, and real estate developers who want to thoroughly prevent future differential settlement accidents and structural cracks, thereby enhancing the durability and asset value of the apartments. It serves as solid technical evidence for determining the suitability of slab foundations and strip foundations, as well as for assessing the necessity of surface improvement and pile reinforcement. It is widely used for fulfilling accountability to clients and as reliable examination materials for ground guarantee organizations.
