Site Investigation | Precision Ground Bearing Capacity Visualization Survey to Optimize Pile Layout for New Construction on Narrow Lots
Ground investigation
Visualizing 3D ground bearing capacity for new building construction on complex ground! By suggesting optimal pile placement, we ensure structural safety while reducing unnecessary construction costs.
This solution is a high-precision ground consulting service aimed at new building construction plans in complex urban multi-layered ground and redevelopment areas. It visualizes ground bearing capacity in three dimensions to optimize pile placement and foundation design. In sites where embankments, alluvial clay layers, and sandy soil layers are intricately intertwined, traditional point investigations often fail to adequately assess local height differences and variations in ground bearing capacity, leading to unnecessary pile driving or excessive safety factor estimates to prevent unexpected settlement. Geotech integrates and analyzes extensive ground database GEODAS, multi-point continuous penetration tests, and detailed soil mechanics test data to accurately visualize the three-dimensional ground bearing capacity structure of the entire site. By directly linking the obtained continuous parameters to the axial and lateral forces in structural calculation models, it calculates the optimal pile placement and the minimum necessary accurate pile lengths according to load concentration areas. This significantly reduces unnecessary excessive piling work and material costs while providing reliable evidence that swiftly clears structural conformity assessments and application approvals, strongly guiding the project to success.

basic information
In this survey, boring investigations accompanied by standard penetration tests and fully automated penetration tests will be conducted at multiple locations to obtain the stratigraphic structure up to a maximum exploration depth of 30 meters. The impact penetration resistance and rotational torque values will be electronically recorded, and after correction calculations for side friction, continuous N-value conversion data will be derived. Additionally, laboratory soil tests will be conducted using undisturbed sample collection to identify soil constants such as the deformation coefficient of cohesive soil, cohesion, and consolidation yield stress. By correlating with our own database GEODAS, we will output a three-dimensional allowable vertical bearing capacity map and differential settlement simulation data.

Applications/Examples of results
It is used for the design of pile foundations and optimization of pile layouts for newly constructed mid-rise and high-rise buildings, reinforced concrete (RC) apartments, and mixed-use commercial facilities in areas primarily undergoing urban redevelopment or where uneven embankments and alluvial layers intersect. It is ideal for design projects that want to preemptively eliminate the risks of differential settlement and tilting due to variations in soil bearing capacity, or that seek to select rational foundation structures that accommodate uneven loads on individual columns. Additionally, it is widely adopted for clean ground surveys in densely populated urban areas with noise and water treatment constraints, as well as for structural compliance evidence for regulatory agencies.
