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

LCLS is ~23% complete on PED 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

LCLS Revised Cost Estimate (Oct04) Revised cost estimate in response to Aug 2004 DOE Review $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

“Old” vs “New” Cost Estimate at L2

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

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%

“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

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).

Details of Revisions-2 Revisions to the OPC Revisions to the Schedule 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

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)

Summary We are ready for CD-2b 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!
