Geodaq provides complete noise and vibration monitoring services to automatically measure sound levels and ground/structural motions and help you manage your construction activity and remain within a safe range and within project limits. A comprehensive monitoring system will help you avoid damage claims to existing structures, disturbance to people, damage to sensitive machinery or degraded performance of precision instrumentation and motion sensitive equipment.

Monitoring Stations
Our remote monitoring systems are designed to operate year-round and continuously record noise or vibration parameters and provide instant notification when project threshold limits are exceeded. We can provide vibration monitoring stations with one or multiple tri-axial geophone sensors. Each remote station is portable, robust and waterproof and designed to operate in harsh conditions commonly encountered at construction sites. We rent our stations with automated monitoring service. Each vibration and/or noise monitoring station includes 24-bit resolution high-speed data converters, 1GHZ controller, wireless Internet modem with service, one or more tri-axial geophones or SS6 Modules, and a high-capacity lithium battery with solar panel. Our remote stations operate autonomously in the field and continuously send data results to our dedicated cloud server.
Monitoring Service
Automated monitoring services come with every monitoring station we rent. Our web application provides real-time results in a password protected portal. View maps showing each station location, get station health status reports and view vibration and noise monitoring results with plots showing allowable threshold levels. Generate daily, weekly, monthly or multi-monthly monitoring reports with our automatic customizable pdf report generator. Each dynamically generated report has up to the minute results. Vibration results can be filtered with specific time intervals and user selectable highpass and lowpass filters to view datasets relevant to the geophone response characteristics as well as project specific requirements.
