Here's a few more pictures of demolition. I don't have any perspective as to how long deconstruction should take, but it seems like they're doing it pretty quickly with the main structure.

This is another video of demolition like before from the SSC page.

Can you trigger an earthquake like that?! Seems unlikely!

Don't know but I wouldn't risk it either way!

I would think they're not imploding it because its kinda really close to homes and businesses...

If done correctly this should not be an issue. How else do you think you get rid of older buildings in downtown business centers of major cities? The only risk that would face is the dust cloud.

TOKYO (AP) -- Demolition of Tokyo's old National Stadium will be completed by September and construction of the new main stadium for the Tokyo 2020 Olympics will start in October, the venue's management group said Thursday.

Demolition was supposed to begin last July but was delayed by irregularities in the bid process and missteps by the Japan Sports Council, which manages the stadium.

The new 80,000-seat stadium is slated to host the opening and final of the Rugby World Cup in 2019.

Plans for the stadium, designed by award-winning British-Iraqi architect Zaha Hadid, have been plagued by problems, including complaints from some prominent architects, who say the design is too big and expensive.

The old National Stadium was the centerpiece of the 1964 Olympic Games.

I think it is quite close in symbolic importance to "the first capital building" given its place in the success of Japan's 1964 bid, and the significance of that success.

Yeah, but it was just an open bowl -- much like Rome's before it, and Mexico after it. I mean there were other LANDMARK venues of 1964. This one wasn't particularly memorable (to me).

It's (rather, it was) certainly not the most startling of stadium designs- but nor was Athens' until they stuck an imaginative roof on it.

I read somewhere (don't have a source right now) that the engineers are having a bit of trouble figuring out how to construct the new stadium.

To begin, the large arches that will support the roof and all are flattened in such a way that they are not as self supportive as most arches are. Because of this, they have to have foundations that go deep into the ground, which costs a lot of money (like that matters anymore)

Also, the arches are actually huge, and getting them through downtown Tokyo to the building site is no walk in the park. There are no nearby canals so they really only have the options of building them in very small parts or somehow flying in all the large parts.

In any case this is a very difficult project but they can't back down now. They have to one up China!

It's a very stupid, UGLY, non-Japanese design they chose!! The unforeseen problems are their own doing. Serves them right for picking that ridiculous, impossible design of a megalomaniac architect.

It'll be fascinating seeing this one go up and seeing how the engineers work through these issues. Our Aquatic Centre by the same architect was definitely the most intruinging build in the run up to 2012; because they built the roof first, then lowered it onto its supporting walls at either end, then built everything else underneath it.

Some of the shapes are so similar to that structure that you'd think they may have to do the same thing again, but this is an order of magnitude bigger so I can't see how that will happen. And speaking of the Birds Nest, the Japan National Stadium seems far more complex since the Chinese Stadium was basically a big bowl stadium with the lattice-work around it. Hadid's huge shapes are part of the stadium strcuture itself! It's going to be a crazy thing to construct.

Anyone know if they're putting webcams on this? I hope they do.

I don't understand why cities keep going to starchitects for these projects rather than modest local firms which will produce something more feasible. Especially for a city like Tokyo which has lots of good architects. Then again, it is the Olympics, so prestige > reason.

The need to have the most modern stadium to showcase the most modern nation was definitely a factor in choosing Hadid's design. I'm not saying the other designs were not modern, they all were. It seems like the JSC wanted to choose a design that would allow the nation to showcase it's engineering capabilities while remaining functional in all situations (hence the requirement for the retractable roof), so when you look at the other options it does make sense why they chose Hadid.

Not to be critical, but this was the entry from one of the Japanese architects (turned stadium preservationist after he lost, weirdly enough) and I'm not too sure it's anything close to the modernity and style the JSC was looking for, even if it was more feasible and functional.

In practice, though, very few people are going to be looking from the stadium from that angle. What matters is what people see from the stands and from the streets. And that design, though "boring", preserves the plaza and the trees around the stadium. That will be more appealing to fans than massive steel arches.

Japan is going to spend three times as much money building a next generation stadium that will end up looking worse than an elegant, understated design. It's this kind of ridiculous decision making (building something even bigger than Beijing's white elephant) that causes the Olympics to be so ruinously expensive.

Olympics: Teardown of National Stadium finally done

TOKYO, May 12, Kyodo

The demolition job of the National Stadium, the main stadium used for Tokyo's previous Olympics in 1964, is finally complete, according to the Japan Sport Council on Tuesday.

The JSC, which governs the stadium, said the wreckage will be completely removed from the premises by the end of September with the construction of the new National Stadium set to start in October.

The main stadium for the 2020 Tokyo Olympics is expected to be finished in March 2019, and will also be used for the Rugby World Cup in September and October that year.

I have some sad but at the same time happy news. After a meeting with the Governer of Tokyo, the JSC has announced that the New National Olympic Stadium will be constructed without the retractable roof. As an additional cost saving measures, some seats will become temporary. There is no mention of removing the retractable seating, so I assume that will stay as planned. However, fear not my retractable roof lovers! Since the stadium will be a concert venue many times after the games, the retractable roof will most likely be built after the games for that purpose.

The best thing out of this is not the money saved, but the fact that spectators wont have to look up at the sky through a wiry mesh anymore!
