Attach IoT sensors to gather and analyze big data on COC Bridges

Since the construction of the first Calgary bridge in 1888, The City and its surrounding area have had built over seventy-five pedestrian, vehicle and rail bridges. Based on the wide distribution of these infrastructures throughout The City, it provides multiple opportunities to not only gather valuable data to monitor bridge health (the load on the bridge and vibrations), but also water flow forces (pressure of the water... more »
Why is this an ambitious idea?

With the load that bridges bear, the particularly tough Calgary climate due to the freeze-thaw conditions and particularly with bridges usually built over water, you will get heaving and concrete will crack more so than other concrete infrastructures. In the past structural health monitoring (SHM) was a very manual process. We have now new opportunities for our society to co-exist and interact with smart interconnected devices that are known as the Internet of Things (IoT), but unfortunately, most of the existing SHM systems are not connected to IoT. This is now an opportunity to build a digital model of the selected bridges in real time by transferring the data by longer range, lower power connectivity products like Wi-Fi HaLow locally for testing and calibration. So, not only would bridge health be monitored, but a dual opportunity to predicting and analyzing climate change impacts and quantifying natural variability are available. This additional benefit may be of greater importance since it involves more than bridges and affects a city in many other areas of concern.

How do we measure the effectiveness of this idea?

The bridge data would be sent to maintenance crews and engineer/scientists using web-based interfaces to view and analyze the collected data in real-time using evaluation algorithms. As for climate data, it could be used for detecting temporal trends; providing information that will allow for a better understanding of the relationships between biological, thermal, and hydrologic data. These would allow The City to understand how the natural system has behaved by comparing historical data with a more precise local IoT sensor readings. This data would provide The City information on how the natural systems are changing from historical trends by maintaining monitoring systems that inform locally specific climate and hydrological model outputs. Using business intelligence and analytics, The City would then be able to determine and plan for those climate impacts that has the highest probability of occurring.

How is this idea attainable through the use of technology or data?

As mentioned in this pages three previous boxes, this can be accomplished by using current technology that allows the ability to gather large amount of data by using tools such as the Internet of Things (IoT) and incorporating longer range, lower power connectivity through products incorporating IEEE 802.11ah devices. This would be then sent to maintenance crews and engineer/scientists using web-based interfaces to view and analyze the collected data in real-time using evaluation algorithms. This same data for climate change would involve more use of Business Intelligence, Analytics and Data Modelling to determine trends and impacts.
