Choosing the right moment to clear snow from roofs of industrial, commercial or institutional buildings often depends on subjective observations or the experience of its occupants. Because snow removal operations are costly and can be logistically complex, it’s best to have reliable data on which to base your decision.
How much weight can the roof really support, and what are the risks associated with snow accumulation or snow removal? Bring building management into the 4.0 era with smart sensors.
Each building operator usually has their own methods of assessing snow and ice build-up on roofs. These include climbing on the roof to get a first-hand look (and getting covered in snow), installing rulers and looking for signs of bowed joists or rubbing doors. Unfortunately, these unscientific techniques are prone to human error!
Alternatively, a specialized firm can be hired to ascertain the roof’s load capacity and evaluate the actual weight of the snow. However, this weight calculation must be carried out repeatedly since it’s only valid for that specific precipitation event.
This is where Tensio’s intelligent sensors come into play: installed on certain steel components (such as beams or joists), they measure the weight of the snow supported by these load-bearing structural components in real time.
The collected data is sent to Tensio servers using IoT technology and compiled in a Web application. The average load percentage based on roof capacity is then displayed, and the snow must be cleared once it reaches 100%.
But that’s not all! To avoid unpleasant surprises, this technology also takes into account the weather forecast for the next seven days based on the building’s location. A model of the anticipated snow is then created to help plan removal operations. If snow clearing is required, building operators receive email alerts before critical thresholds are reached.
While snow accumulation may ultimately cause a roof to collapse, there are many other benefits to removing snow before its weight interferes with the structure’s load-bearing capacity.
Having access to data allows you to adapt and thus optimize your operations while targeting areas with greater snow accumulation. The sensors also provide access to centralized load data of all buildings belonging to the same company.
It also eliminates the need for roof inspection rounds, thereby optimizing the time spent on these evaluations and reducing the costs associated with building maintenance.
This also provides another benefit: it increases your roof’s service life by minimizing access and thus potential damage. As we know, the roof is at risk of being damaged every time someone goes on it and plows it.
With Tensio’s sensors, your buildings adapt to environmental challenges, allowing you to deal with such changes safely and efficiently.
The maintenance of a warehouse or factory roof and removal of snow no longer has to depend on senior personnel who “knew” the building (and took their knowledge with them when they left)!
Gone are the days of roof damage, accidents and injuries related to snow removal, and, in extreme cases, roof collapse. Smart sensors allow you to ensure the safety of the building’s occupants and people with access to the roof. Everyone wins!
Choosing Canam means benefiting from in-depth expertise and peace of mind. By adding Tensio’s intelligent sensors, you extend this peace of mind to infrastructure management.
Such innovation is in line with the design-build approach favoured by our teams: for this reason, all our prefabricated buildings built with Murox can be equipped with Tensio’s intelligent sensors, an option that’s been available since the beginning of 2022. Innovation that meets your needs!
