How the Skydance Bridge Was Built How the Skydance Bridge Was Built Presentation Transcript

  • Oklahoma City SkyDance Bridge: for Sooner Spaces
  • HISTORY OF THE SITE AND PROJECT
  • 2005-2006 Downtown to the River Studio
  • The letter from the mayor which has invited team SXL as only one of five to compete …team SXL is the underdog against internationally recognized larger firms..each team receives a $10,000 stipend to prepare their concept
  • OUTPUT TEAM
  • Most of us had not designed a bridge ..what we lacked in experience we made up with passion
  • PART ONE OUTPUT TEAM
  • THE PURSUIT OF INSPIRATION
  • Oklahoma…where the wind comes sweeping down the plain…..
  • A history of aeronautics..from Wiley Post to modern defense weapons
  • Power from the wind: vertical structures are bold markers on the horizontal plane
  • Route 66 icons
  • PROCESS: DESIGN THINKING
  • May 2008
  • May 2008
  • May 2008
  • Single Truss – Twist June 2008
  • Wall Cloud July 2008
  • Wind July 2008
  • Single Truss Knife July 2008
  • The male scissortail courts the female by performing acrobatic maneuvers which involves diving recklessly towards the ground..this is known as the “skydance”
  • Oil rig structures, which have led to the state’s booms and busts, are analogous to the spirit of hardworking Oklahomans and the scissortail ..they achieve a lot with a little…bridges must also do the same
  • The first crude model
  • Gathering frequently and often very early in the morning the team shares and debates ideas
  • July 2008
  • July 2008
  • Scissor July 2008
  • Aug 2008
  • After collectively spending over 1,400 hours…without any real pay (the $10,000 stipend was mostly spent on the model, coffee and donuts)… the passionate team proudly presents their concept..which wins..a victory for the underdog
  • THE COMMISSION
  • INPUT PLAYERS City of Oklahoma City Mayor Public Works Community SHPO ODOT WIND TUNNEL TESTING OUTSIDE CONSULTING ENGINEERS (Modjeski and Masters) FABRICATORS PRODUCT MANUFACTURERS FHWA FEDERAL AVIATION
  • PART ONE OUTPUT TEAM DUKING IT OUT
  • July 2010: Working towards 90% Submittal Long story short… $5M Budget expands to $12.8M due to forces beyond the team’s control such as changing codes, added requirements and scope by Client. At this point the Client informs the team that they must redesign the bridge to meet the new budget of $6.8M ..and by the way still meet the same deadline and provide an iconic presence. A challenging task to say the least.. …..However the team comes up with a new structural approach of using a truss bridge with the “bird” as an independent sculpture which is architecturally much closer to the original concepts and the budget goals are met. Success!
  • Engineering Issues Another long story told even shorter. Amidst working on the project codes were changed which required an unprecedented increase in minimum performance of the structure to withstand loads from wind from multiple directions, seismic, ice, a vehicle driving over the bridge..ALL at the same time….Our engineers saved the day and made it work..On time and budget
  • How Stan Carroll made it all work in 3d…..a screen shot of how he programmed the model…magical
  • The Creative Process within Fabrication
  • Oklahoma City SkyDance Bridge: Bridge to Design Thinking
