  1. LCLS Schedule and ContingencyLowell Klaisner, SLACApril 24, 2002 • Civil Construction Schedule • Technical Construction Schedule • Alternate Schedules • Contingency • Plans for CD-2 Lowell Klaisner, SLAC

  2. LCLS Site Plan Lowell Klaisner, SLAC

  3. FY05 Civil Construction • Injector • Clean Room for Laser • Buildout alcove including PPS entrance module • Shield wall between injector and linac • Injector utilities • Accelerator • Reconfigure utilities • Undulator Hall • Remove FFTB beam dump to allow removal of equipment through the end then finish Undulator Hall enclosure • Research yard road work • Construct tunnel between Hall A and Hall B Lowell Klaisner, SLAC

  4. FY06/07 Civil Construction • FY06 • Construct Hall A • Install Utilities in the Undulator Hall • FY07 • Construct Hall B • Beneficial occupancy of the experimental floor by July 2007 Lowell Klaisner, SLAC

  5. FY05 Technical Construction • Injector • Install Laser • Install gun and accelerator sections with microwave plumbing • Accelerator • Install gallery equipment • Complete modifications through L1 • Construct components for bunch compressors • Fabricate supports etc. for electron beam components in the Undulator Hall • Undulator • Remove existing equipment from FFTB • Receive and measure the first article of the undulator segments Lowell Klaisner, SLAC

  6. FY06 Technical Construction • Injector • Complete installation • Begin commissioning with electron beam • Accelerator • Install beam compressors • Install all electron beam components upstream of the undulator • Undulator • Install first undulator segments in the Undulator Hall Lowell Klaisner, SLAC

  7. FY07 Technical Construction • Injector • Continue commissioning • Accelerator • Complete installation • Beam to BSY by January 2007 • Beam to the electron beam dump as soon as undulator available. • Undulator • Installation complete June 2007 • First coherent light by September 2007 • X-ray Optics • Near hall installed by June 2007 • Far hall installed by September 2007 Lowell Klaisner, SLAC

  8. Alternate Schedules • Extend Civil Construction one year • First light remains in FY07 • This could reduce the peak funding requirements • TEC increases from $216 million to $220 million • Delay Start to FY 06 • Increases cost due to “standing army” (or decrease in staffing in FY05) • Advanced procurement in FY05 • TEC increases from $216 million to $231 million Lowell Klaisner, SLAC

  9. Contingency • Top Down • Similar systems installed recently • Similar civil construction completed recently • Bottoms up • Basis of estimate at level 6 of the WBS • Assign contingency based on the risk associated with each basis of estimate Lowell Klaisner, SLAC

  10. Basis of Estimate Input Form Lowell Klaisner, SLAC

  11. Basis of Estimate Lowell Klaisner, SLAC

  12. Contingency Assignment Lowell Klaisner, SLAC

  13. Plans for CD-2 • More mature design • Refine estimates • Revisit level 6 estimates • Conduct internal cost reviews • Improve the Basis of Estimate • More quotes • More mature design • More research • Ready for an Independent Cost Estimate January 2004 • Ready for an External Independent Review in Jan 2004 Lowell Klaisner, SLAC
