Breath of fresh air – Hurontario LRT construction crews keep an eye air quality

It’s not all about the tracks, trains and stations. While construction ramps up on the Hurontario light rail transit (LRT) project, crews must keep watch over a lot of different things. Air quality around the site is a big one. Find out how technology plays a part.

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.
