“TQF South has developed a monitoring process that is thorough and meticulous, utilizing 24-hour, unattended construction monitoring microphones and geophones to monitor and protect existing structures. During pile driving operations, the vibration monitors are set up adjacent to existing structures to control and reduce the vibration to allowable levels. The exact locations of seismographs are decided based on construction site clearances, the ability to protect instruments, and cellular signal reception, ensuring comprehensive coverage.
The seismographs are programmed to record maximum peak particle velocity (PPV) data every minute and collect waveform data when PPV exceeds pre-set limits. An alert will be emailed to designated personnel if the threshold levels are reached. This proactive approach enables us to identify the source of vibrations and trigger SMS alarms when vibration levels established by the district are exceeded, ensuring prompt action on potential issues.
The deployment of the monitors would include placing and securing the monitoring equipment. Setup work would also include verifying equipment function and that the included cellular modem is communicating with the host. TQF South will remove the equipment at the end of the monitoring period. Regular weekly maintenance would consist of checking the power and operation of the equipment and making any needed adjustments to the equipment setup. Data can be supplied daily via email and/or a weekly summary report. The weekly report would include a summary of the previous week’s readings and provide up-to-date information for your use.”
