  • 10. SR 520 Program Schedule 10
  • 11. SR 520 Pontoon Construction Project 11
  • 12. Why is the Pontoon Project needed now? • Constructing and storing pontoons  are key elements in catastrophic  failure planning.  • If the floating bridge failed,  available detour routes would be  overwhelmed with rerouted traffic. • Recovering the bridge after a  catastrophic failure will require new  pontoons. We estimate it would  take approximately three years to  construct enough pontoons to  restore the SR 520 bridge. Existing SR 520 pontoon 12
  • 13. Advanced Construction Methods and Engineering • Support accelerated schedule,  reduce risk, and minimize costs • Field test for pontoons, i.e.,  form systems, concrete mixes,  full‐scale mockups of pontoon  sections • Advertise in Summer 2009‐‐ Posted on WSDOT Contract Ad  and Award Web site • Located in Grays Harbor
  • 14. Use existing facility at Concrete Technology Corporation • Expedite pontoon  construction to stay on  schedule • Does not have capacity to  build all the pontoons • Construction of pontoons to  begin in 2010 
  • 15. Two Sites in Grays Harbor 15
  • 16. How are pontoons built? • Prepare site – Excavate a basin, drive piles, pour concrete slab. – Stabilize sides of basin with concrete walls; seal off from open water with a gate. – Construct support facilities. • Construct pontoons – Assemble forms around steel frame. – Pour concrete into forms to create pontoon. • Launch pontoons – Fill basin with water. – Open gate and use tugboat to tow pontoon to moorage location. – Drain basin and repeat process for other pontoons.
