  1. LCLS CD-2B Evaluation Details supporting the increase to the LCLS TPC 05 Jan 05

  2. LCLS Project Cost Estimate (Apr04)Presented to B&R at EIR in June 2004 LCLS Cost Estimate $273M AY TEC $315M AY TPC ~29% on work remaining LCLS is ~23% complete on PED

  3. LCLS Revised Cost Estimate (Oct04)Revised cost estimate in response to Aug 2004 DOE Review LCLS Revised Cost Estimate $315MAY TEC $379MAY TPC Mar09 CD-4 addresses FY05 CR and adds schedule float ~35.2% (was 29.5%) contingency on work remaining LCLS is ~37% complete on PED

  4. “Old” vs “New” Cost Estimate at L2

  5. Revised Contingency Assessment (Nov04) Increased Contingency in PM (staffing-startup uncertainties), Injector (drive laser) and Conventional Facilities (safety, tunneling, commodity prices)

  6. Revised LCLS Summary Schedule – Oct04 Critical Path Increased float to 214 days (10.5 mos.) from 140 days (7 mos.) Through Linac and B.O. for e-beam dump Increased explicit float on all CF B.O. dates from 2 mos. to 3 mos. Softened 1Q-05 for continuing resolution Extended CD-4 to March 2009 from Sept 2008 Improved schedule + later CD-4 increased schedule contingency from 16% to 24%

  7. “New” LCLS Organization • Increase senior level expertise • Chief Scientist will oversee project physicists • Construction Safety professional • Dedicated procurement group • The E-Beam systems and X-Ray systems Oversight staff will add a management layer between the system managers and the project office • Laser Group Manager to provide expertise to the entire project

  8. SLAC-LCLS Procurement Organization • Dedicated Procurement Cell (co-located) • LCLS Procurement Manager (TBD) • Dual reporting to LCLS PD (Galayda) & BIS AD (Jobe) • Signature Authority up to $2M is proposed • Technical Lead (Jamison) • Conv. Fac. Lead (Patten) • Administrative Aide (TBD) • LCLS Procurement Consultant • Desaulniers (experience from TJNAL, APS-ANL) • Executing PMCS Award & Laser RFP • Executed A/E Award & Co-author CM SOW • LCLS Procurement Team; • Provides input to procurement schedule, • Signs off and executes APP’s, • Evaluation team member

  9. Details of Revisions-1 • Revisions to the LCLS Scope of Work • No Additions to the LCLS scope. • Revisions to the TEC • Added Chief Scientist in FY05 and beyond • Added Construction ES&H Professional in FY05 and beyond • Added Construction Consulting Support • Added Construction Procurement Support in FY05 and beyond • Added Construction Procurement Consulting • Revised CM model such that CM acts as SLAC’s principal agent to initiate and manage general contractor and/or subcontractor procurements • Added 2 Independent Cost Estimates (ICE) for Conventional Facilities construction costs • Added $5.1M TEC funds to the Title I construction cost estimate upon recommendation from the A/E (Jacobs Engineering).

  10. Details of Revisions-2 • Revisions to the OPC • Added $600K in FY08 to address legacy issues in SLAC Linac Sectors 20-30 • Added start-up teams of physicists and engineers and additional start-up funds to address uncertainties in legacy issues and electric power costs. • Increased Management Reserve from $500K to $5M • Added Laser Group Leader in FY05 and beyond • Added RF Gun Physicist in FY05 and beyond • Revisions to the Schedule • 60-day explicit float in Beneficial Occupancy dates • Minimum critical path of ~214 working days of float wrt CD-4

  11. Details of Revisions-3 • Revisions to the Contingency • Increase contingency guidance in the Injector Drive Laser • Increase contingency guidance in Conventional Facilities to address the uncertainties with the T1 cost estimate provided by the A/E and the recent independent (Wightman) cost estimate. • Explicit schedule contingency of 60 days added to each Beneficial Occupancy (BO) milestone. • Revisions to the Proposed Funding • FY05 – No Changes • FY06 – No Changes • FY07 - From $106M (90M TEC, 16M OPC) to $121.5M (105.5M TEC, 16M OPC) • FY08 - From $49M ($34M TEC, $15M OPC) to $66.0M ($50.5M TEC, 15.5M OPC) • FY09 – From $0M to $31.5M ($10M TEC, 21.5M OPC)

  12. Summary • A revised cost and schedule estimate for the LCLS project based upon the recommendations of the Aug04 Lehman Committee has been developed. • LCLS technical scope is unchanged • Base Cost increased to add PO staff and CF estimate • from $213M to $236M • Schedule softened and extended • Increase schedule contingency from 14% to 24%. • Current schedule takes into account FY05 CR. • Base Cost contingency was increased. • from 29.5% to 35.2% on remaining work • Increased management staff. Dedicated procurement organization. • CF Construction Management model is in focus. SOW in draft. • We are ready for CD-2b • Areas to work on in next 6 months; • With full FY05 funding, hire key personnel • Prepare FY05 long-lead procurements (LLP’s). APP’s are ready for most LLP’s • Continue to add management, procurement and construction staff. • Construction start is March 2006!
