The second phase of the project is the complete redevelopment of the LookOut floor which begins in October. The CN Tower will again be partnering with PCL on the project.
"It's in early stages but the redevelopment will be the entire floor, updating HVAC and things like that as well, but again it's about the view...and really just making it a world class observation," said Jones. "We're competing with other towers around the world that are popping up in New York, London, Chicago and we want to stay modern and of value to the people that are visiting Toronto."
Improved energy efficiency was another goal of the project. The new glass units contain Thermochromic film as part of the structure, which is a technology that allows the glass to adjust its darkness based on sunlight and external temperature to improve energy efficiency and make it easier to take photos.
The first phase of the project involved replacing two out of the 12 column bays on the LookOut level with new floor-to-ceiling glazing overlooking the city and the waterfront. The column bays consist of seven sections each. Each glazing unit measures 1.61 metres wide by 2.62 metres high, with a thickness of 2.74 inches. Each panel of glass weighs 1,000 pounds.
