The London Olympic Stadium

Welcome to the London Olympic Stadium!

I have now been in the London Olympic Stadium four times. Even though we are sitting high in the second deck, the sight lines are great. We can see all the action. My only minor complaints are that the scoreboard is hard to read (it’s not my fault I have bad eyesight, the London Olympic Committee should be taking care of my needs!) and that when the UK fans cheer loudly (which they do a lot), I can’t hear what the announcer is saying. Pretty minor things to be fussing about, huh?

We’re lucky, we can see the Olympic flame from our seat inside the Stadium.

There have been some complaints regarding the Olympic flame. The only people who can see the flame burning inside the cauldron are people who have tickets to attend an event (i.e. track & field or athletics as they call it here) in the Olympic Stadium. Since I am one of the lucky ones who has tickets to the Olympic Stadium, this has not been a complaint of mine.

On the flight over to London, Virgin Atlantic offered a documentary about the construction of the stadium. It was very insightful and easier to understand than the technical article my dad showed me from Civil Engineering magazine.

The London Olympic stadium seats 80,000 people and was built in east London at a cost of 486 million pounds. One of the cornerstones of the London Olympic bid was the eco-friendly and flexible nature of the Olympic Stadium. The stadium was built in such a way that it can be partially dismantled after the Games leaving the lower bowl, comprised of the track and 25,000 seats.

There were many challenges the architects and engineers faced when designing and constructing the stadium. Over two hundred building were demolished in east London to create space for the stadium. Some of these buildings produced toxic waste so the soil needed to be decontaminated. In the end some of the soil was re-used for landscaping and another 800,000 tons of soil were removed from the area. There was believed to be over two hundred un-exploded bombs from World War II buried in the ground that had to be considered during the construction  to prevent an unplanned explosion. The land allotted for the stadium is surrounded by rivers on three sides and the area was not large enough for the traditional footprint of an 80,000 stadium. Designers got around this by “pulling” out food preparation areas and moving them to outside the stadium.

Some of the steel girders that support the upper bowl.

The upper bowl of the stadium is comprised of steel components that are bolted together and can be un-bolted and removed after the Olympics. The roof, too, is a stand-alone feature of the stadium, weighing 450 tons. The roof is not connected to the lower bowl of the stadium. The roof has four components: an outer ring, an inner ring, 12,000 meters of cable, and 25,000 square meters of fabric. The roof is designed to shelter the fans as well as block wind for the athletes so that any marks run are not wind-aided or wind-hindered.

There are fourteen light towers, weighing 500 tons, attached to the roof. Each tower provides 14,000 watts. The lights are all angled properly to illuminate the track but to not create any shadows or glare for the spectators.

You can see the light towers attached to the roof from this shot inside the Stadium.

The grass on the field was grown off-site and then cut into rolls and brought to the stadium. Three hundred and sixty rolls of the turf were brought in. The transfer of the grass from its off-site location into the stadium needed to be done in less than twenty-four hours for the grass to stay alive.

Throughout the construction, workers had to deal with typical London weather issues. In the winter of 2010, work stopped for two weeks during a freeze. High winds were often a concern when working with the cranes and lifting heavy steel components into the air.

In the end, over 5,000 workers helped to build the stadium. The circumference around the outside of the stadium is one kilometer (anyone for 5 X 1000 meter intervals?). There are 338 kilometers of cable, twelve kilometers of ventilation ducts, and eleven kilometers of drainage.

Number of days to build the London Olympic Stadium: 1,000

Number of toilets in the London Olympic Stadium: 1,387

Number of memories for the athletes and spectators inside the London Olympic Stadium: infinite

There is something about being inside an Olympic Stadium and seeing the Olympic flame burning that is indescribably special. Knowing a little more about the construction of said stadium adds to the experience. Thanks, London! I’ll consider my poor vision and hearing to be my own problem and give you an A for your stadium!

The London Olympic Stadium gets an A from me.
