Canals help Singapore mitigate floods during stormy weather. Situated in the eastern part of Singapore, the Bedok Canal was due to be expanded for a greater holding capacity along a 1km stretch. To hold the newly constructed canal banks in place, the contractor deployed metal I-beams in three sections of the canal.
In accordance with Singapore regulations, a total of 14 vibrating wire strain gauges and 6 vibrating wire load cells were installed to monitor 20% of the newly deployed I-beams.
As these I-beams and their sensors were distributed sparsely across the 1km development area, deploying a cable-based monitoring system for the sensors was too costly. Instead, the option was to take manual readings using handheld readers a few times a week. As the expansion work progressed, the main contractor required more frequent readings, rendering the manual method impractical and inefficient.
At this point, the switch was made to Ackcio Beam to automate monitoring processes. Ackcio supplied 1 Ackcio Gateway and 6 Ackcio Vibrating Wire 8-Sensor Nodes to assist with this project. The Nodes were mounted close to the I-beams and wired to their load cells and strain gauges. The Gateway was placed near the site office and powered using a solar panel and rechargeable battery.
Using Ackcio Cloud data readings from the Nodes could be analysed, processed, and reported every 15 minutes.
As a result, Ackcio Beam provided our client with an efficient and reliable wireless monitoring solution with real-time manageability for a 70% lower cost compared to taking manual readings.
