CN Tower Turns 28 And Innovative Glass Floor Turns 10 Canada NewsWire
It took three months to engineer and test the floor to ensure its safety and durability. In keeping with the CN Tower's high safety standards, the Floor continues to undergo safety and durability tests on a regular basis. To provide the clearest view possible, a protective surface panel is changed every year.
Three workmen spent 10 days installing the floor piece by piece framed within a steel grid. Installation was conducted without a false floor underneath because there would be no way of removing it later. Thus the installation team was suspended in mid air by safety ropes where they could feel the winds whipping around them and see the 342 m (1,122 ft) distance down to the ground.
