The Olympic Stadium is shortlisted for the Stirling Prize, a prestigious architecture award, for its innovative design. The Stirling Prize winner will be announced on October 13, 2012. “As with the other London 2012 Olympic Games buildings, Populous’s Olympic Stadium had to be designed to be used post-games. So the 80,000-seat stadium will shrink down to a 20,000-seat stadium after this summer. In order to be able to achieve this, Populous designed the stadium as a sort of kit of parts, said principal Phillip Johnson in a video on RIBA’s site. ‘The roof itself is separate from the upper tier so that in theory you could take down the tier without taking down the roof, or vice-versa.’ The stadium will be the lightest one ever built, with 11,023 tons of steel.” -Lindsay M. Roberts, Architect Magazine The Stirling Prize is the highest prize of the Royal Institute of British Architects (RIBA). Read why the Stadium was chosen on the Stirling Prize website here.

We suggested Dow go an open tender to wrap the to Cooley Group to find a stadium as part of their fabric that would work. That Olympic sponsorship. A was the team: Dow, Rainier, mutual friend (who had and Cooley.

Cooley would start in 1896. engineer and produce the fabric. Dow’s initial conversation with Rainier was about the And then the question was – feasibility of such a big project – with such special How do we take constraints. what’s essentially a What would it take to wrap a very cool picture and stadium of this size? Could it make it into reality in be done using polyethylene less than a year? materials, so that the process and materials would be sustainable? Could the results be repurposed?
  8. 8. Getting Down to Work Dow is an international leader in A very over-simplified explanation of Elastomers. Rainier is an fabric: pellets are pushed through an international manufacturer of extruder, resulting in material that’s innovative fabric and display thin, wide, and flexible. Extruders like products. Cooley Group is an fabric that’s roughly 90% liquid and industry leader of engineered fabrics, 10% solid. But in order to meet the focused on using sustainable British Standards, the fabric had to chemistry. be about 10% liquid and 90% solid. That’s approximately the make-up of All three companies provide roofing membranes. solutions. And it’s a good thing, because wrapping the Olympic Our first challenge and the hardest Stadium was one big exercise in one we faced: to take technology problem-solving. used for horizontal surfaces (roofs) and apply it to vertical textiles The panels had to be strong, flexible, (banners rising in helixes over 80 feet beautiful – they were an integral part high, from the ground concourse to of the architects’ vision for the the upper tier of the stadium, stadium. They weren’t an “add-on” or supported by tensioning cables). a “decoration.” It was like pushing mud through the They were an architectural element, extruder. The material was too stiff, it a crucial part of the aesthetic and didn’t spread, it wouldn’t print. functional design. Rainier doesn’t engineer the chemical composition of fabric – we What Rainier, Dow, and Cooley make things with fabric – so we quickly found after starting to work listened in while Dow and Cooley together was that the existing fabric tackled the hard science. we’d planned to use wouldn’t work – it meets the USA fire standards, but They went back to the design board – not the British Standards. That and created an entirely new eliminated the initial material – then formulation of infrastructure several others. membranes.
  9. 9. Producing the Fabric Cooley Group produced the fabric for the Olympic Stadium Wrap. When a sample of new material would arrive at the Rainier facilities, we’d test it on our printers. We lost 3 printer heads in the process, and several valuable months. When we thought we were close, Rainier’s Display Division Manager Charlie Rueb flew down to Cooley’s plant in South Carolina. As the fabric rolled off the extruder, Charlie deemed it fit to try – again – on our printers. A look at the process:  To make fabric, you have to run a minimum of 1,000 yards.  The process takes 8 hours - if there are no problems. And you don’t know anything about the quality of the material until you’re done.  Plus, the fabric passes through the extruder three times, multiplying the potential for failure: This is what the raw material of polyethylene looks like before it’s o Pass 1. Apply the black-out layer. melted & run through the extruder – o Pass 2. 1st coating of white. it comes in pellets. o Pass 3. Flip it, 2nd coating of white.

  12. 12. Making the Panels How the Olympic Wrap panels were made in 9 steps Keep in mind that this was And it is representative of an unusual project, with Rainier. Because everything unusual requirements – and we make here is custom, this an untested, unproven is operations as usual – in fabric. that nothing is usual! This is the process of We call ourselves solution Rainier making the Olympic providers, because we solve Stadium panels, including problems. retries and final successes. STEP ONE: Color tests and print trials We run the fabric through our printer to see how it does with color.
  13. 13. At this time, we have 6 monthsMaking the Panels STEP TWO: Testing a mock-up panel to test it, print it, cut it, sew it, pack it, ship it, and install it. We print a panel, cut it, and hang it. The fabric doesn’t work. See all that texture across the red (right)? The fabric is puckering. Because the fabric is puckering, we have to raise the printer head. As a result, we end up with another problem: banding, those vertical streaks of lighter and darker ink. The gap between the head and the media is too large – so the ink is too spread out. We redesign the fabric (which means going back through that entire fabric production process) and try again. Until it works.
  14. 14. Making the Panels When we finally get the fabric right… rolls of it arrive on the Rainier production floor. Once we have new fabric, we mock up a new panel. Look at that smooth expanse of blue. That’s what we are after, and now that we have it, production can begin in earnest.
  15. 15. Making the Panels STEP THREE: Printing the panels Working with this new fabric was like working with cardboard. Every single step of the process – from printing to installation – presented new challenges. The Rainier team came up with new solutions and solved each problem as it arose.
  16. 16. Making the Panels STEP FOUR: Cutting the panels Rainier uses state-of-the-art automated cutting machines. As with every other step of this project, cutting the fabric presented unique challenges. Because of its stiff, thick composition, we cut all 306 panels by hand– extremely unusual on our shop floor. We get the job done, no matter what it takes. Rainier owner Scott Campbell takes a turn at cutting the panels while VP of Sales Bruce Dickinson gives him a (rather far-off) helping hand.
  17. 17. Making the Panels STEP FIVE: Sewing the pockets Employees work their way along the length of the panel to sew the second layer of the pockets. Every pocket is given double layers of fabric to protect against abrasion from the cable. Every panel has “pockets” running their lengths – like seams on garments. The pockets hold the cables that eventually twist to create the helixes. Remember, every panel is over 80 feet long!
  18. 18. Making the Panels STEP SIX: Laying out the panels for finishing touches The rope you see here is a drawstring, used to pull the cable up the length of the pocket. What look like white dots at the bottom of the panel are essentially punched holes. In the installation, the panels are bolted to a clamp bar at the bottom and top.

Because of the fabric stiffness and the In this picture, you can see the before (left) – thickness of the double-layer pockets, the white rolls of fabric – and the after (right) – fabric is folded and wrapped around bolts, bolts of finished panels packed away in rather than “rolled.” individual cubbyholes.

  21. 21. Installing the Wrap To install the panels, Rainier partnered with FabriTec, a division of ShadeUSA based in Dallas, Texas. The original plan allowed three months for installation, starting in December 2011 – but that was before all the challenges making the fabric. In the first week of April 2012, FabriTec did their test install of a set of panels. The results were not good – it took 5 days to do 3 panels. At that rate, it was a 2 year installation job to put up 306 panels. Changes were made to the templates to allow for faster installation – and install methods were re-engineered to meet the condensed timeframe. Installation of all 306 panels began on June 11, 2012. It was finished July 20 – the last day any work was allowed on the stadium. That’s right – FabriTec installed all 306 panels, each 80 feet long, in just over a month. Instead of 12 weeks, they did the installation in 5.
