Challenges of Demolition Work in Residential Areas
T Construction Company was tasked with demolishing a local hospital situated in a residential area, necessitating strict adherence to noise and vibration level regulations throughout the demolition process.
For this project, the company required a cost-effective monitoring system that could continuously monitor the site and send email alerts in case of abnormal readings. Additionally, it needed to easily share data with multiple stakeholders.
Another significant constraint was the absence of Wi-Fi network at the demolition site, making it essential to use wireless equipment capable of transmitting data via mobile networks.
For these reasons, the T&D Wireless Data Logger RTR-500 Series was chosen to meet the remote noise and vibration monitoring needs for this demolition project.
Equipment Used in the Monitoring System
This system utilizes sound level meters, vibration meters, and T&D wireless data loggers to collect site data and transmit it to the cloud.
The main equipment used includes:
- Sound Level Meter
- Vibration Meter
- RTR-505-VL Remote Unit
- RTR-500MBS Base Unit
- RTR-500 Repeater
- T&D WebStorage Service for cloud data storage
Note: The RTR-500 Series has been discontinued and replaced by the RTR500B Series, an improved version.
Operation of the RTR-500 Series System
The system is configured for sound level meters and vibration meters to measure values from the demolition area. The measured values are then output as voltage data and recorded by the RTR-505-VL Remote Unit.
Data from the Remote Unit is automatically collected by the RTR-500MBS Base Unit. The Base Unit then transmits the data via a 3G mobile network to the T&D WebStorage Service, a cloud data storage service.
This allows stakeholders to remotely monitor data via mobile devices without needing to be physically present at the site.
On-Site Equipment Installation
In practice, a total of 4 monitoring sets were installed within the demolition area, with each set comprising:
- 1 Sound Level Meter
- 1 Vibration Meter
- 1 RTR-505-VL Remote Unit
Additionally, two RTR-500MBS Base Units were installed nearby to collect data from the Remote Units via the 3G network.
Due to unstable wireless communication in some distant spots, an RTR-500 Repeater was used to extend and stabilize the communication range between the Base Units and Remote Units.
Results of Use
The use of the RTR-500 Series system allowed an environmental monitoring company, located over 150 miles from the demolition site, to continuously monitor noise and vibration data remotely.
Data uploaded to the T&D WebStorage Service is accessible via mobile devices, enabling stakeholders to check the site status anytime, anywhere.
A significant advantage is that personnel do not need to be constantly present at the site, yet continuous data monitoring is still possible remotely.
Advantages of the Remote Noise and Vibration Monitoring System
This system enhances the efficiency of demolition site monitoring in terms of safety, standard control, and operational cost reduction.
Key advantages of the system include:
- Continuous monitoring of noise and vibration.
- Email alerts for abnormal readings.
- Remote data monitoring via mobile devices.
- Easy data sharing with multiple stakeholders.
- No need for on-site Wi-Fi or LAN.
- Reduces the need for on-site personnel.
- Reduces communication costs by using MVNO SIM cards and mobile packages.
- The RTR-505-VL Remote Unit has a high-capacity battery, suitable for use in construction or demolition sites.
Alerts Help Prevent Problems from Escalating
One of the system's highlights is its ability to send alerts when monitored values are abnormal. If noise or vibration levels show a tendency to exceed set limits, the system immediately sends an email notification to relevant parties.
This allows users to identify when and where problems are likely to occur on the site, enabling quick corrective action before issues escalate into major problems.
Conclusion
The RTR-500 Series is an ideal system for remote monitoring of noise and vibration, especially in construction or demolition sites without Wi-Fi or LAN.
For T Construction Company, this system allowed continuous data monitoring from the hospital demolition site, reducing the burden of on-site supervision, lowering costs, and enabling the team to respond to anomalies more quickly.
Although the RTR-500 Series has been discontinued, the currently available RTR500B Series is an improved version suitable for similar remote monitoring applications.
