CD-2 ECP Preparations

As part of the CD-2 process, we aim to establish a comprehensive cost and schedule baseline. This begins with the PDR baseline and incorporates detailed cost and schedule inputs from all stakeholders. We have top-down estimates but now require more granular details. Items impacting the baseline include recommendations from PDR, PBR, EIR, and discussions with OFES regarding scope inclusion. Additional changes pertain to several WBS categories, necessitating further evaluation and analysis. Your timely feedback by this Friday is crucial for incorporating these adjustments into the revised estimate.

  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
