Hurontario LRT construction crews keep an eye air quality

While construction ramps up on the Hurontario LRT, crews must keep watch over air quality.

Mar 26, 2021

Building new rapid transit lines can kick up a lot of dust. Literally.

While, the Hurontario LRT will help get cars off the road and reduce overall greenhouse gas emissions – construction can be messy.

Construction vehicles and other related activities can lead to a temporary increase in emissions and particulate matter in the air.

That’s why the construction team at Mobilinx, builder of the Hurontario LRT, is using state-of-the-art air quality sensors to keep a high-tech eye, and nose on things.

The devices monitor Particulate Matter, which consists of a mixture of solid and liquid droplets found in the air made up of dust, dirt, soot or smoke, and other particles that can’t be seen.

Air quality is one of the most important conditions to monitor on an active construction site.

By monitoring the air, crews can assess air quality changes as soon as they occur and act quickly to identify and implement mitigation measures to address the change in conditions as required.
