Civil Projects

Civil Project Monitoring

Civil engineering projects include the construction of roads, bridges, airports, schools, hospitals, dams and other municipal buildings. The activities used throughout these projects, such as excavation or pile driving, are known to create vibrations that could potentially damage surrounding structures. Other activities such as blasting or demolition, can also generate a force of air, known as air overpressure, which can set off car alarms or even break windows. While there are many municipal, state and federal regulations that govern the vibration, air overpressure or even noise levels, it can also be a best case practice for the engineering firm or project owner to keep a monitoring record.

Monitoring equipment from Instantel lets you record vibration, air overpressure and/or noise. Using the recorded data, you can compare transient levels to real-time levels throughout the duration of the project. Recorded data can be viewed almost immediately. Warnings and alarms can be triggered based on pre-configured trigger levels that you set, and these can different for each job. If for example, you are pile driving in close proximity to a subway tunnel, bridge or other structure, real-time data allows you to adjust those activities before you exceed regulatory limits or concerns develop. When you connect a siren or lights to the Instantel monitoring equipment using a remote alarm controller, you can receive on-site visual or audible notification of the warning or alarm. Notifications can also be sent to you, or any party you choose. These notifications can be viewed on computers, laptops, tablets or smartphones and an historical record of data can be maintained to protect you from claims and liability.


Micromate Monitoring System

Micromate

Micromate

Monitoring unit with 4 available channels: three channels for recording vibration on three planes and one channel for air overpressure or noise data.

SmartGeo

Triaxial SmartGeo

Records ground vibration in three planes: transverse, vertical and longitudinal. Does not have to be leveled when installed.

Linear Microphone

Linear Microphone

Records air overpressure data on a linear scale from 2 to 250 Hz with a range of 100 to 148 dB(L) (2 to 500 Pa).

Sound Microphone

Sound Level Microphone

Class 1 Sound Level Microphone records noise (or sound) levels. The Sound Microphones meets the IEC 61672-1 standards.


Borehole GeophoneThe Instantel system combines a Micromate monitoring unit with a variety of sensors. Our system is scalable, as your monitoring needs change, sensors can be added or removed. If today’s job requires vibration monitoring but tomorrow’s job requires vibration and noise, simply add a noise microphone. Add on the SmartGeo™ from Instantel and you can monitor vibration at the base of a building today and then on the pillar of a bridge tomorrow – without needing to adjust any internal sensors and without using any specialized mounting equipment.

Instantel also offers the Minimate Pro6. It has six available channels and a wide array of sensors. With the Minimate Pro6 you can record vibration data from two geophones on one monitoring unit. The Minimate Pro can record at up to 65,536 samples per second. When monitoring at this sample rate, the Minimate Pro6 can record and even play back sound clips.

Whether you are using the Micromate or the Minimate Pro monitoring unit, if you need to monitor a nearby sewer line or tunnel you can record with a borehole geophone. Resistant to the natural elements found in a borehole, such as water, the triaxial borehole geophone measures vibration on three planes: transverse vertical and longitudinal. It is designed to be lowered into a borehole to the depth of a nearby sewer or tunnel so that you can monitor the effects of vibration at the source.


Minimate Pro Monitoring System

Minimate Pro4

Minimate Pro4

Monitoring unit with 4 available channels: 3 channels for recording vibration on 3 planes and 1 channel for air overpressure or noise data.

SmartGeo

Smart Geophone

Records high frequency vibrations in 3 planes: transverse, vertical and longitudinal.

Linear Microphone

Linear Microphone

Records air overpressure data on a linear scale from 2 to 250 Hz with a range of 100 to 148 dB(L) (2 to 500 Pa).

Sound Microphone

Sound Level Microphone

Class 1 Sound Level Microphone records noise (or sound) levels. The Sound Microphones meets the IEC 61672-1 standards.


Instantel’s equipment can be installed in short-term or long-term projects. Our equipment is designed to withstand extended exposure to the conditions of a jobsite and can be installed permanently for the length of your project. When you connect an Instantel monitoring unit, you can automatically send recorded event data to your local computer or server using Instantel’s Auto Call Home™ technology. Event data can then be analyzed using THOR™, our desktop software, or they can be sent to our cloud-based data hosting site, Vision™.

Histogram ReportOur proprietary Histogram Combo™ recording mode ensures that you never miss an event. With Histogram Combo mode you can monitor the job site 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 you are monitoring activities that induce repetitive vibrations, like pile driving or dynamic compaction.

Some regulatory bodies and project requirements state that the event reports need to be hosted online. With Vision by Instantel, you can provide 24/7 access to your project’s stake holders. Data recorded by an Instantel monitoring unit that is connected to a modem can automatically be sent to Vision. With Vision, you can create customized reports and display data from other sensors that may be installed on your jobsite, like tilt, wind or crack gauges. Vision’s custom reporting options can be used to give an overview of all the information you stakeholders need to see. You can also create reports so that you can see your event data over the week, month, or even over the duration of the project.

Each piece of the Instantel system is designed, manufactured and calibrated by Instantel. Every part of the system is easy to use and can be quickly configured. With Instantel you can guarantee that you’ll never miss an event.
