Site Investigation | Precision Ground Bearing Capacity Visualization Survey to Optimize Pile Layout for New Construction on Narrow Lots

Visualizing continuous ground bearing capacity in the construction of new buildings on narrow plots with moving-in restrictions! By conducting space-saving high-precision surveys, we prevent excessive pile length design and optimize pile placement.

This technical solution is a high-precision ground investigation service aimed at new building sites in urban areas where large machinery cannot easily access. It visualizes soil bearing capacity and optimizes pile placement through space-saving automatic continuous measurement. In densely populated urban areas or construction sites facing narrow streets, it has been difficult to set up conventional large boring machines, often leading to designs that assume excessive safety factors without obtaining sufficient data on the supporting layers, resulting in overly long and numerous piles. GeoTech employs a compact self-propelled automatic penetration device, approximately 830mm wide, allowing for smooth equipment transport even in tight spaces, and automatically obtains Nd values and rotational torque up to a maximum depth of 30m with high precision in 200mm increments. By clearly capturing the inclination of supporting layers and changes in soil bearing capacity from continuous data collected at multiple points within the site, we derive a rational pile placement design that eliminates unnecessary pile driving and excessive lengths, in conjunction with structural calculations. The speedy investigation procedure, which eliminates mud water treatment and large-scale temporary works on site, contributes to significant reductions in construction time and costs while considering the surrounding environment.
