The problem

Pipe-to-soil readings near an LRT line swung with train traffic.

The owner needed to know which crossings were affected, by how much, and what to fix first.

Our approach

  1. 01

    Plan

    Nine crossings and a reference site chosen with the owner.

  2. 02

    Log

    72 hours of synchronized logging across all sites.

  3. 03

    Analyse

    Interference correlated with traction current; two sources isolated.

  4. 04

    Recommend

    A ranked mitigation plan with costs for each step.
