Exploration of Raw Data

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!?)

Percentage Averages

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.

Plan view

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


One thought on “Exploration of Raw Data

  1. I like all your mathematical studies and the precision they imply in terms of how they determine the limits of your roofscape – I would make sure to include all your calculations and draw the design process through diagrams showing the daily fluctuations, how you determined the heights of the roofscape, the design of the hydraulic, telescoping elements etc. Remember to draw rather than write big chunks of test so that the complex information becomes easily digestible and visually appealing.
    I like the idea about playing with the time through the tide and exposing the piers through this but how do you intervene in this field of piers? Do you have low-level walkways between the piers that only reveal themselves at low tide? Would be nice to see more of you in this scenario rather than just the piers.
    I’m a bit confused about the changes in the design – Is the complex of blocks that you had previously being replaced by this single block as seen in these new drawings? I think the raised back end of the building might obscure the roofscape from being viewed from the city so not sure if thats the right way to go – instead perhaps the roofscape end should be raised to make the fluctuations of the stock exchange more apparent/ theatrical?
    I like the idea of integrating the public activity of ringing the bell onto this roofdeck – it could be an interesting moment to merge the public roofscape with the private interior for the traders – where would this pocket of space have to exist in your design to merge these parallel worlds briefly?
    Some of the views you have generated today remind me of this project by Diller, Scofidio and Renfro for the ICA in Boston: http://www.arcspace.com/features/diller-scofidio–renfro/ica-boston/ – perhaps to break up the blockiness of your project you could think about cantilevers – or their signature move of a dropped down amphitheatre to get views out into the water, similar to the one we saw on the Highline that hovers above the road – yours could be hovering above the roofscape as a pod for the bell to ring? or could be a theatre looking back at the city? or looking into the activity of the traders?
    I think it would be interesting to really think about bringing the public spectacle of the stock exchange in closer proximity to the private world of the traders while still keeping them largely separate as a way to increase the tension between these two often parallel worlds.
    At the moment the approach from Chelsea towards the building doesn’t feel inviting or dramatic enough – I think we need to see the dynamic shifts of the roofscape and the pathways needs to express the piers a bit more as well as feel more designed?
    Perhaps you can play with the timeline of the area (and of your project) by inscribing the landscape with the story of the site? It could be a nice way to incorporate your research into the Berengaria, changes in industry etc into the project?
    In the Pier 55 reference, the first image in the carousel is a nice overview of the piers in context as seen from above the water, it would be nice to construct a version of this image with your project included – I like how in the Heatherwick version the piers appear as a texture almost level with the water but in yours its even better since you integrate them into your design.
    Lots of good developments but you can still take it further and push the design more! Looking forward to seeing the portfolio on Tuesday and how you reorder all the material to tell the story of your project!
