Over the last few days I have been doing further work and research on the parameters for the roofscape and carried on with design work.
Whilst working on the roofscape, I was trying to figure out how each peak would be formed and how many moving elements I would need to show the percentage gains/losses of the stock. Originally, I looked at the overall gains and losses, but these are done per day, not per 5 minutes. From this, I found the raw data from tuesday’s stock market, and extracted the information I needed for both the Dow Jones and the 30 ‘blue chip’ companies that make up the Dow. This raw data was the previous close value, and from graphs I extracted the highest value (from a 5 min interval) and the lowest value. I then used these to find the difference between the value and the close value and then turned it into a percentage, which gave me the highest and lowest percentage differences which I could then use as an index and parameter for calculating the movements of the roof peaks (can you tell I did A-Level Statistics and actually enjoyed it!?)
My findings showed that the percentage values were not as high as I originally thought they would be (the daily percentage increases are around 2%-5% from that same day) with the highest %increase of 1.486% and the lowest at -3.277%. Using this, I have rethought the measurement of the peak and set the limits as 5% and -5%. I am hoping to calculate another days stock just to see if there are any higher values, but if not, I will use these parameters.
I havent had time to draw this out, so will state instead. I intend to have 10 sections for each peak (5min interval) which allows each section to represent 0.5% (which should give a good variation in peak size, even at the smaller values). As many of the values are between 0 and 2, this still allows for at least 4 blocks to move.
Setting the size of the peaks at 400mmx400mm, my conversation with Charles allowed me to confirm that 10mm thick edges for each section is strong enough for a person to stand on, so the smallest section (no.10) would be 220mm. I would have the cut off for standing on them at section 6, 300mm as this also starts to become quite high and the sections become further apart. I will work on a technical drawing of this to understand it easier, in addition to how the system works with the water from the river.
I have done some further design work, which has allowed me to think about the shape and how to combat the rigidness of the project. I wanted the building to seem quite imposing from the front with no real obvious entrance and using perforated metal to hide windows and the front facade. The steps leading down to the columns run the length of the building which I think give it a nice linearity and also reminds me of some of the other imaportant NYC public buildings that have large steps at the front, such as the Met and the NY Public Library. The positioning of the steps allow people to interact better with the piers but also allow them to look back at the city skyline (you can see the empire state from the location) At high tide, the steps lead down to the waterfont:
And at low tide the water receeds and the piers become more exposed so you can walk among some of them:
Having explored further with the shape of the building in plan, I’ve looked at a staggered plan which also mimics the erosion of the piers at the end, further into the hudson.
Adding a metal facade also gives the illusion that the higher floors overhang the lower floors, but it also guides people into areas. The main server room will lie directly below the roofscpae, giving the largest block private spaces for the traders, but also giving me more space for the public space to get people onto the roof. I decided to put back in a small arboretum which mainly houses the stairs to gain entrance to the roof, but creates a nice public space for people to walk though and gives another visual represntation of the server power. The metal facade will create light patterns in the space and almost be a sort of secret garden.
I am still trying to figure out the back view as I think it does look a bit messy, but just wanted to quickly show the roof going into the server space at the back. Im also not sure about the higher level at the front of the building. This does divide up the roof level and provide almost a viewing platform over the moving roofscape, and also gives the building height at the front, but not sure if it obscures the roof too much and makes the back view look messy, and also not too sure about where or when to staop the metal wrap around facade. Any comments would be great.
I have also been thinking about ‘The Bell’ aspect- I wonder if the resetting of the roofscape could provide a theatrical element to the bell that people could see? Similar to the ball drop on NYE, the facade would reset itself with a countdown to the opening of the NYSE and all the elements would slowly drop back into position. This could add another dimension to the timetable of the new NYSE.
For tuesday, as its a portfolio review, I am going to work on the layout and editing of my portfolio and print out final pages for review (in the A3 format the porfolio will be submitted in). I’m also hoping to come with some binding ideas in addition to furthering the design proposal with maybe some card models and plans sections etc.
Also, a friend saw this proposal and brought it to my attention. There are currently plans to build an extended garden on the hudson at pier 55 (mine’s 58) by Heatherwick Studios, which is a nice concept and interesting landscape support system
