Two of Cape Town's icons in one shot

The Green Point Stadium and Table Mountain
Just after the rain stopped
Upper Green Point suburb
and Table Mountain in the back ground
Lions Head peeping over Signal Hill

This is what the North and the South side of the 2010 Green Point Stadium looks like on Aug 21

The North side
To me this is the back side of the stadium since I can only see this side when I drive passed the Radisson Blu Hotel
North West side, I had left my new cam with the wide angle lens, in my car along the beach road, so these are all with my old Canon Powershot s5 IS

It took them 3 days to do the middle part of the lightweight aluminium frame, compare this shot with this one

Clear glass on the cantilever trusses of the 2010 Green Point Stadium

It was a few minutes before the six o'clock "end of the day" blaring of the siren, heralding the end of a day's work for the day shift This was a dreary sunset the sun didn't come out much but I wanted to show the progress they had made on installing the clear glass on the 16m wide inner tension ring which will incorporate the pitch lighting

Once the roof is finished the roof will be a ‘ring of fire’ similar as in Berlin’s Olympic Stadium in Germany.

Near midnight on August 19 2009 Construction work on the facade of the 2010 Green Point Stadium in Cape Town

The Green Point stadium has one primary façade system, which is a cable-suspended ETFE
membrane similar, to the lower skin of the roof structure.

The membrane forms a continuous, taut but flexible skin, clipped into a lightweight
aluminium frame. The frame is stiffened against the massive concrete structure of the stadium by means of round hollow steel sections. Vibrations occurring in the façade itself,
either from emitted noise or from wind vibrations imposed on the structure, are absorbed through the stiffening rods into the building’s massive structure.

Less than 15% of the bowl’s inside surface lets through sound waves directly to the outer walls of the building. In addition, only about 70% of the stadium façade is covered only by the vertical mesh membrane Some of the areas that are directly under the roof edge will have a more carefully detailed double façade skin application, which will perform better than the average outer façade

This is what the 2010 Green Point Stadium and the Green Point Common looks like when a storm hits Cape Town

Wet cold and plenty of rain several highways were closed as well as roads in town due to floods Rough sea conditions, with swells of more than 5m and gales of speeds of more than 65km/h in some areas.
I haven't really experienced the gales today but certainly saw and felt plenty of rain

Even in the worst of weathers this beast is still a beauty

Click photos to see large
The Green Point Common was and is one big mud bath

World Cup 2010, Green Point Stadium, a work in progress on August 17

Just 2 random images of today
I was out this evening and just drove past the back of the stadium, there is allot still to be done before december 14, I am glad I am not in the shoes of the construction manager, it even makes me nervous when I see how much there is still to be done, yet the promise is still "finished by December 14 2009 "

Yes ! The Laminated glass roof on the 2010 World Cup Green Point Stadium in Cape Town is complete ! ) On August 16 2009

Click on the photo and take note of 2 things
They have started installing the clear glass (on the left) for the inner ring of the roof and also
notice the pattern of the laminated glass panels in the middle, they had to cut it and like a jigsaw make it fit.
They are not working on the outside tonight but have been every night this last week
The roof
Is located above the highest level of seats, and contains an accessible roof includingthe ‘Ring of Fire’ lighting and media zone, with catwalk access into and through theroof structure.The roof is a critical component of the interior architecture. As a suspended roof plane, it focuses attention downwards onto the playing field. At the same time, the underside of the roof surface, hovering above the spectators, operates in a way similar to the façade. The translucent mesh skin under thesteel cable and truss structure will act as a luminous disc during days of sunlight and will transmit the colour and atmosphere of the day into the stadium interior. The double skin design of the roof further makes it possible to accommodate (unsightly) services therein and, for example, avoid the use of pylons for the floodlighting. It fulfils an important function as far as noise attenuation is concerned. The roof structure is designed as an acoustic "body” with its own internal volume. The principle of utilising the air space inside the body of the roof as a noise buffer is one of the compelling simple and active design principles applied to the stadium. The key to this principle is the requirement that the “inner” (lower) and “outer” (upper) surface of the roof structure must have different densities and therefore display different acoustic performance characteristics.
