  1. CD-2 ECP Preparations What is Needed

  2. Background • As part of the CD-2 process, we need to establish a fully supported and documented cost and schedule baseline • Starting point is the PDR baseline, including the detailed cost and schedule backup details you each provided • We have made tops-down estimates of each with some input from you, but now we need the details!

  3. Items Impacting Change in Baseline • PDR Recommendations • PBR Recommendations • EIR Recommendations • Discussions with OFES on what scope should be included • In several instances scope that was removed from PDR baseline re-instated

  4. Changes to WBS 12 • Evaluate impact of 350°C bakeout (special study – already in FY2004 WAFs) • Include 350°C bakeout • Other miscellaneous changes • Redesign of port extensions and use of skip welds • Re-evaluate viability of manual welding • Evaluate best method to minimize vacuum leaks

  5. Changes to WBS 14 • Conduct additional R&D program • Cold test all 18 modular coils • Install 2nd winding line • Other miscellaneous changes • Re-evaluate access through VV – more design and analysis • Re-assess tolerance budgets for assembly • Re-evaluate bolting of modular coil flanges • Re-evaluate properties of conductor without lubricant

  6. Changes to WBS 16 • Re-evaluate scope of WBS 16 – especially scope of auxiliary utility lines • Other miscellaneous changes • More design and analysis need for LN2 system • Re-evaluate coil service runs in close confines of cryostat

  7. Changes to WBS 18 • Add additional time and effort for pre-assembly operations • Add full-size mockup to plan

  8. Changes to WBS 75 • Re-evaluate time needed for final alignment of field periods • Reinstate power testing and e-beam mapping • Reinstate full cryostat installation, testing, and cooldown • Reinstate cold power testing prior to first plasma

  9. Other Changes(Do Not Require Your Input) • Schedule stretch as result of funding constraints and new scope • Escalation due to re-sequencing of tasks – BUT WE DO NEED YOUR APPROVAL OF WHAT WAS DONE! • WBS 12-18, 21, 22, 25, 31, 36, 38, 41-45,51-57, 61-64, 74, 75 • Review resource-loaded schedule • Thin black line is the PDR baseline • Thick blue line is the re-sequenced task (estimate NOT changed) • You can discuss any necessary changes with Ron

  10. What is Needed by this Friday • New detailed cost estimate backup that incorporates these changes • PDR spreadsheets provided to each of you • Resubmit as new file: • YYMMDD_CostBackup_121_PLG • We will call you to discuss if we have questions
