- Markets Residential, Structural Monitoring, Geotechnical Engineering
- Services Vibration Monitoring, Settlement Monitoring, Structural Protection
Project Description
NicNevol Engineering Services performed vibration and settlement monitoring during adjacent construction activities at 454 Royal Tern Road in Jacksonville Beach, FL. Monitoring ensured that pad fill, dewatering, and compaction operations did not cause damage or measurable movement to the nearby residence.
The program utilized an Instantel vibration monitor with geophone and settlement surveying using precision leveling equipment. Vibration thresholds were established following U.S. Bureau of Mines criteria (Warning Level = 0.4 in/s PPV; Stop-Work Level = 0.5 in/s PPV). The maximum vibration measured was 0.025 in/s PPV — well below the defined limits — and no structural movement was observed.
Monitoring concluded that construction activities produced no adverse vibrations or settlements, confirming compliance with applicable structural protection standards.
NicNevol Responsibilities
- Installing and operating vibration monitoring equipment.
- Conducting settlement surveys during and after construction.
- Establishing vibration thresholds and reviewing exceedances.
- Documenting field data and preparing monitoring logs.
- Providing a final report confirming compliance with structural protection criteria.
Project Highlights
- Monitoring period: Aug 30 – Sept 23, 2021.
- Construction monitored: pad fill, dewatering, compaction by vibratory roller and bulldozer.
- Equipment: Instantel vibration monitor + geophone; survey level for settlement tracking.
- Maximum vibration recorded: 0.025 in/s PPV (<< 0.4 in/s limit).
- No structural settlement or movement observed.
- Result: Activities did not produce damaging vibrations or settlements at the residence.
