Project Challenge

The metro excavation required continuous observation of ground movement and pore water pressure during tunnel boring operations. Manual inspection alone could not provide the reporting frequency required, especially during high-risk excavation stages near existing infrastructure.

SoilCreate Solution

SoilCreate configured an automated monitoring package combining in-place inclinometer arrays, piezometers, data loggers, and remote telemetry. The system captured deformation trends and groundwater pressure changes, then delivered structured data for engineering review.

Result

The monitoring workflow helped the project team identify movement trends earlier, reduce dependence on manual site checks, and maintain a clearer record of ground behavior throughout the excavation sequence.
