The Workers’ Compensation Board of British Columbia is monitoring a collapse at a Coquitlam construction site that left a gaping hole in its shoring wall on Thursday.

Video posted to social media shows a crack growing in a shoring retention wall at the excavation site near Foster Avenue and North Road. Soil begins to pour out of holes at the centre of the crack, just above a row of anchor plates.

Within a minute, a massive section gives way to tonnes of soil, forming a gaping hole. As dirt piles up at the base of the site, the anchors can be seen sticking out.
