Demolition

Demolition activities can generate significant ground vibrations that may affect nearby homes, buildings, sewer systems, and other infrastructure. The use of explosives can also produce air overpressure, creating a powerful pressure wave. Under certain meteorological conditions—such as low cloud cover—this shock wave may travel horizontally and extend farther than expected, potentially increasing its impact.  Even when demolition is carefully planned and executed under optimal conditions, it can raise concerns among neighboring property owners and occupants. In addition, post-demolition cleanup typically involves intensive operations with heavy equipment and fully loaded trucks removing debris, which can further contribute to vibration, noise, and community disruption.

Using monitoring equipment from Instantel, vibration, air overpressure, and/or noise levels can be recorded and monitored simultaneously, as they occur during the demolition activities.  Since recorded data can be viewed almost immediately, project teams can make informed adjustments in real time — before regulatory limits are exceeded or before community concerns arise.   Pre-configured warning and alarm thresholds can be established based on project-specific requirements, regulatory limits, or site conditions. These trigger levels can vary from one job to another and are customizable by sensor. When thresholds are approached or exceeded, automated notifications can be sent to designated recipients — whether that includes site personnel, project managers, consultants, or regulatory authorities. Events, devices, and project management can be accessed on computers, laptops, tablets, or smartphones, ensuring visibility wherever you are.  In addition, a secure historical record of monitoring data is maintained. This documented evidence can be invaluable in addressing complaints, demonstrating compliance, and protecting against future claims or liability.

Our equipment is designed to withstand long-term installations and extended exposure to the conditions of a demolition site.  With Vision II software, events are automatically synchronized and can be viewed on any internet-connected device.

The Micromate Plus system integrates a vibration monitoring unit with a triaxial geophone, sound level, and linear microphone to simultaneously measure ground vibration levels, noise, and air overpressure, providing a complete picture of generated impacts. Devices can be configured to record in Histogram-Combo mode continuously, capturing background vibration levels while still generating detailed waveform reports for events that exceed defined trigger thresholds. The histogram event reports deliver peak particle velocity (PPV) values at set intervals, ensuring comprehensive vibration profiling throughout the monitoring period.  

With Vision II, event reports can be automatically scheduled for delivery at a specified time or at the end of each day.  For projects requiring continuous updates, Vision II supports 24/7 automated data sharing. Users can control stakeholder notifications and access permissions, for example, granting project owners access to events, projects, and scheduling, while limiting regulatory bodies to viewing compliance reports only.  With Vision II and its Live Data capability, recorded measurements can be viewed in real time, allowing you to evaluate conditions as activities occur. This immediate access to data enables proactive adjustments to operations before regulatory limits are exceeded or community concerns arise.
