  1. San Francisco-Oakland Bay BridgeEast Span Seismic Safety Project

  2. Self-Anchored Suspension Span consists of a 160-meter single steel tower with a main cable and inclined suspenders supporting two steel orthotropic decks of a 385-meter main span and a 180-meter back span. The workshop will concentrate onidentification of Constructability issues for the tower and orthotropic boxes. SAS Constructability Workshop 04-012064

  3. Contractors that plan to bid 04-012064 SAS/YBI contract steel, fabrication firms that plan to submit estimates steel plate suppliers, and Caltrans Project Manager Participants

  4. the capacity of the domestic steel market to produce plate steel for orthotropic boxes and tower what is fabricators ability to fabricate and transport pieces what affects contractors ability to bid the project due to the above issues Purpose is to identify

  5. contractors Constructability concerns concerns with the tower “pick” Purpose is to identify

  6. a noun Constructibility? Constructability?

  7. public and construction safety improvements cost reductions and enhanced quality improved and shortened project schedule What can Constructability achieve?

  8. Construction planning and Constructability analysis which integrates the diverse and quite often conflicting criteria into a coherent solution Constructability

  9. optimum use of construction knowledge and experience in planning, design, procurement & field operations to achieve overall project objectives (Caltrans Project Engineer Academy) Constructability

  10. bid process design - bid - build considered throughout project delivery up to award Constructability

  11. no bidders risk financing no materials or cost prohibitive materials environmental permitting Constructability is consideration and resolution of barriers to bids open

  12. are there responsible bidders is there a competitive bidding process bid process design - bid - build what do we do to make our PS&E package attractive to the bidder? Constructability is consideration and resolution of barriers to bids open

  13. SAS Constructability Workshop 04-012064bids open January 2003 , advertises September 2002, and open for westbound traffic in 2006

  14. where are we on May 13, 2002?

  15. Tower Saddle (Upper Portion) S-Wire Cable Wrapping MacAlloy Bars BUY AMERICA WAIVER APPROVED BY FHWA

  16. What are the necessary production rates for delivery of plate steel, fabrication, erection?

  17. lessons learned on other projects that might relate to Constructability of the tower and orthotropic boxes?

  18. use the roster to keep in touch keep up to date by webpages, dbe, tollbridge, office engineer bullets and power point presentations on toll web page BID IT, BUILD IT What next
