Blowing up, but not as we know it…

Canadians consider inflatable tunnel to segregate site and pedestrians.

Keeping pedestrians and demolition separate is a constant challenge, even on a fixed site around which a perimeter hoarding can be erected. But imagine trying to replicate that degree of segregation on a site that gradually moves through a busy city centre.

Well, those canny Canadians have addressed just such an issue; and the solution is as unlikely as it is innovative. That solution is a giant, inflatable tunnel that will envelop construction works during part of the day.

Designed by KANVA, an architecture firm in Montreal, the 14 metre wide and 11 metre high tunnel will serve to protect pedestrian traffic from the construction and the nearby buildings from dust and debris.

The city is also ready to schedule entertainment within the $3.8 million tunnel to attract more visitors. While work beneath the road is taking place, the tunnel will be covering the construction work, but when the sidewalks are being worked on, the pedestrians will walk underneath the tunnel. No vehicles will be allowed on the road until the work is complete.
