BC PLACE – $458 MILLION NEW RETRACTABLE ROOF – COMING 2011 – VIDEO

THE $458 MILLION RETRACTABLE ROOF – SLOWLY TAKING SHAPE, PIECE BY PIECE.

The $563-million construction at BC Place Stadium is more than halfway through. Revealing over 7500 square metres of clear blue sky, the new $458-million retractable roof will turn BC Place into a year-round, open-air facility and a new architectural signature for our province. The cable-supported roof is the biggest of its kind in the world and will allow for tailoring the atmosphere for any event, the transformation will take just 20 minutes.

However, the roof will have some limitations, it will not be able to open or close in the rain or in winds of 60 kilometers an hour or more. BC Place general manager, Howard Crosley stated that our stadium wasn’t set up to handle the very significant weight of a metal retractable roof of the type you see in other stadiums. Therefore, the roof’s limitations in wet weather are a result of the building’s structure. The architects were forced to choose a fabric rather than a metal retractable roof. The 55,000 seats in the stadium will always be covered.

ROOF FACTS
•  the blue-sky opening is 100 metres by 85 metres, same size as the field below
•  the fabric roof section retracts into the centre of the opening, where it’s hidden inside of a pod above the videoboard
•  each of the support masts is 47 metres tall. All together, the structure is like 18 suspension bridges, each around 200 metres long
•  the new roof is much more energy efficient than the original roof, saving 25% on energy costs (or about $350,000 per year)
