LUMSA - ROME


Lumsa University chose Sibyl to monitor the structural integrity of four buildings in proximity to the demolition, excavation and construction of a new building on their campus.

Structural monitoring involved measuring static deformations (inclinations, deflections, lengthening, shortening) and dynamic stresses (accelerations) on pre-existing structures and on bulkhead poles along the perimeter of the excavation.

The Numbers

  • 50 sensors
    • Thermometers
    • Inclinometers
    • Accelerometers
    • Strain sensors
  • 1 km of optical fiber 50 Hertz per sensor
  • System installation time: 2 days

AUTOSTRADE PER L’ITALIA - NAPLES


Sibyl monitors a network of fans installed in the tunnel covering of the Naples autoroute.

Monitoring involves the measurement and control of static deformations (inclinations, axial deviation) of fan brackets, as well as the temperature and vibrational state of each fan.

The Numbers

  • 28 fans
  • 9 sensors per fan
    • Thermometers
    • Accelerometers
    • Strain sensors
  • 5 km of optical fiber
  • Sampling frequency: 1000 Hertz
  • Monitoring: 24/24h - 365d/year

AUTOSTRADE PER L’ITALIA - VAL DI SAMBRO


Sibyl controls the convergence and longitudinal deformations of the Val di Sambro tunnel on behalf of Autostrade.

The Numbers

  • 80 sensors - 30 km optic fiber
  • 7800 data acquired per second - 4 PLE
  • System installation time: 18 days 24/24h
  • Monitoring: 365 d/year

AUTOSTRADE PER L’ITALIA - IMOLA


Sibyl monitors the structural integrity of the A14 highway Imola overpass.

Structural monitoring involves the measurement and control of static deck inclinations, deflection measurements of bridge beams, and dynamic modal parameters.

The Numbers

  • 74 sensors
    • Thermometers
    • Inclinometers
    • Accelerometers
    • Strain sensors
  • 3700 data acquired per second
  • Sampling frequency: 50 Hertz
  • System installation time: 5 days
  • Monitoring: 24/24h- 365d/year

METROPOLITANE MILANO - MILAN


Sewer monitoring involves data acquisition of Brillouin distributed sensors installed in the sewer pipes of the city of Milan.

Sibyl measures vertical and horizontal pipeline deformations, the level, speed and flow rate of the sewage and controls anomalies due to parasitic infiltrations from outside the pipeline. All data is indexed and dashboards were created to facilitate interpretation.

The Numbers

  • 2 Brillouin loops
  • 37 Km of Brillouin distributed fiber 24/24h
  • Monitoring: 365d/year
