Industry Problem

Civil Infrastructure Structural Monitoring monitoring risks and field constraints

Monitor civil infrastructure deformation, strain, vibration, displacement, tilt, cracks, settlement, GNSS movement, cable force, seismic response, and construction-stage structural behavior.

Structural risks

  • bridge cable force redistribution
  • civil structure vibration and modal drift
  • strain accumulation on load-bearing members
  • settlement, tilt, crack, and displacement growth
  • dam, slope, and tower deformation trends

Monitoring challenges

  • distributed acquisition across large structures
  • mixed static and dynamic channels
  • GNSS displacement and strain data fusion
  • long-term trend review
  • turning structural measurements into RFQ-ready monitoring scope

Environmental conditions

  • traffic vibration
  • wind loading
  • temperature expansion
  • rain and humidity
  • reservoir level fluctuation
  • construction-stage adjustment
  • slope and geotechnical deformation
