Construction Sites

Construction sites should be completely closed to the public whenever possible.

Install barricades that are detectable to long cane users in a colour that contrasts with the surroundings. Ensure all construction equipment is safely placed behind the barricades.

Construction barricades should be at least 1,070 mm high. Snow fencing is not an effective barricade because it’s not solid and it can entangle long canes.

When chain-link fencing is used, construction grade tarpaulin fabric should be used on the walkway side of the fence, to a height of 500 mm. This will prevent canes from getting stuck in the chain-link fencing.

Scaffolding along a sidewalk adjacent to a construction site.

Walkways adjacent to a construction site must be free of debris. Use a minimum walkway width of 1,200 mm to allow for the passage of guide dogs and their handlers.

When scaffolding is used, overhead clearance should be at least 2,030 mm, measured from the walkway surface to the underside of the lowest part of the scaffold frame.

Define a clear path of travel by placing light fixtures underneath scaffolding at regular intervals and at a uniform height. Maintain consistency of lighting levels along the pathway.

Scaffolding should be detectable by long cane users. This can be achieved by installing a rail on the sides of the scaffolding, along its entire length, to a height of at least 300 mm above the walkway surface.

Signage for construction sites should follow the guidelines presented in the Signage section.
