Demolition
Hydraulic hammers, wrecking balls, and explosives detonations are all key contributors of demolition work that create intense ground vibrations, air overpressure and noise levels that can easily exceed regulatory standards.
Why Monitor Your Demolition Project?
Demolition activities are known to create strong vibrations that can potentially damage nearby homes, buildings, sewer lines and other structures. Explosives detonations can also cause air overpressure which produces a force of air. Depending on meteorological conditions such as a low cloud ceiling, the shock wave can spread out horizontally and have a greater destructive impact than anticipated. Even when these activities are performed under best-case scenarios, they can cause concern to neighboring buildings and homeowners. The cleanup operations are often extensive with heavy machinery and fully loaded trucks hauling away the rubble.
How Instantel Can Help
Using monitoring equipment from Instantel, you can record and monitor vibration, air overpressure and/or noise levels on and around your demolition site. As recorded data can be viewed almost immediately, you can adjust your demolition activities before regulatory limits are exceeded or before concerns develop. Warnings and alarms can be triggered based on pre-configured trigger levels that you set, and these can be different for each job. Notifications can be sent to you, or to any party you select, and these can be viewed on computers, laptops, tablets or smartphones. An historical record of data can be maintained to protect you from future claims and liability.
How A Micromate Monitoring System Connects Using THOR and Vision Software Systems
Our equipment is designed to withstand long-term installations and extended exposure to the conditions of a demolition site. You can install Instantel monitoring equipment permanently for the length of your project. Using Instantel’s Auto Call Home technology and a modem connected to the monitoring unit, event reports can automatically be sent to your computer so you can analyze the data using THOR, our desktop software, or they can be sent to our cloud-based data hosting site; Vision.
THOR
Our proprietary Histogram Combo recording mode ensures that you never miss an event. With Histogram Combo mode you can monitor the job site using a work shift scheduler or even 24 hours a day and still get reports when levels are exceeded. Your report will show you the peak vibration levels at set intervals throughout the day, but it will also give you a waveform report if there are any exceedances. If your equipment is connected to a modem, the waveform events will automatically be sent using Auto Call Home, then at the end of the day your histogram events will be sent. This allows you to quickly analyze the waveform events and determine if the activities are causing the exceedance or if there is an alternative reason. Histogram Combo mode is ideal when monitoring activities that produce repetitive vibrations throughout the day such as demolitions from wrecking balls, hydraulic hammers and heavy removal equipment.
Vision
Some project requirements stipulate that project owners, regulatory authorities or other stakeholders must be informed of the monitoring activity and all exceedances. Instantel’s cloud-based data hosting solution, Vision, can provide 24/7 access to event data. Data recorded by your Instantel monitoring equipment can be automatically sent to Vision when the system is connected to a modem. With Vision, you can control stakeholder preferences. For example, you could limit project owners to view events and reports without download access, while a regulatory body could view the events and reports with download access. Vision also lets you create custom reports. You can add event data from other sensors, such as temperature or strain gauges, and show your data over the day, week or even over the entire duration of the project.
