  2. Linac Status and ScheduleInstallation Coordination • Review 2007 installation issues • Component status • Installation status • Safety • Schedule • Summary

  3. Linac-Issues From Last Review • Concerns of completing 2007 installation (Linac/BC2) • Not getting final RP approval to turn on the beam • There were issues with BC2 shielding and engineer redesigned shielding to accommodate RP requirements • Not receiving repair coils for BX24 on time • BX24 coil was repaired and delivered to SLAC in December 2007. Magnet was measured and installed in January • Not having repair opportunity days, ROD, available to complete BC2 installation • RODs were made available to install BX24 magnet, remaining BC2 earthquake supports and BL22

  4. Linac- 2007 Installation

  5. LTU & E-Dump Components Status • LTU and E-Dump design complete except: • Spot shielding in LTU • Most components are available for installation with few exceptions of • LTU vacuum chambers expected complete deliveries from vendor by 6/15/08 • Spot shielding for LTU not approved by RP yet, however some parts are being fabricated • Single Beam Dump in fabrication completed by the end of June • TDUN in fabrication • Supplier delivered two BYD magnet: one measured and second BYD magnet is being prep for magnetic measurements. The third and last magnet is expected to be delivered by June 20th.

  6. Components Status

  8. LTU and Dump Installation Status • LTU and Dump installation are managed by Kathleen Ratcliffe • Using lessons learned from last two installations and following the same ISMES • All LTU stands are installed in LTU and vacuum components installation have started. Open vacuum installations have just granted under co-occupancy (i.e. interconnect vacuum chambers to the components) • Cable installations has begun • Completed all pre-assemblies in building 26 and are staged in “End Station A” for installation

  9. LTU and Dump Installation Status • Awarded two Davis Bacon contract for LTU: installation of support stands and installation of magnets (80% complete) • Awarded one Davis Bacon contract for E-Dump: installation of support stands, e-dump steel and e-dump components installation (not fully available for installation) • Submitted purchase requisitions for TDUND, Single Beam Dump and Zero Degree Shielding

  10. LTU and Dump Installation Status • Mechanical Fabrication department has started component installation in BTH and BTH west • Critical issues that could delay completion of installation: • LTU drifts not available in time for beam line vacuum pump down • Availability of Single Beam Dump and TDUND from MFD • Spot shielding design approval from RP • Ion Pump power suppliers not ready in time for vacuum (plans to use local power supplies) • Wire cards for Wire Scanners are not yet in fabrication • Potential problem between dump supports stands and dump housing, this issue is being resolved by the installation integration engineer • Installation of pit steel is on hold until Crane is available. Crane is certified but has not been transferred to SLAC because it is not on permanent power

  11. Installation Assurance & Safety • Tailgate meetings before every shift to discuss daily activities and any safety related issues • Job walk with contractors before start of each job • Installation weekly meetings • Instituted Quality Control check list sign off for both components and post installation • Safe Performance Observation walk (minimum once a week for managers)

  12. Safety Approval Documents • Statement of Work (SOW) – These documents are written by installation manager for Davis Bacon contractor and are submitted to Building Inspection Office, BIO, for approval. BIO requires 11 signatures for approval • Davis Bacon contractors are required to submit and approval of following documents: • Industrial Injury and Illness Prevention Plan (3 approval signatures) • Site Specific Safety Plan (4 approval signatures) • Job Safety Analysis (3 approval signatures signatures) • Rigging Plans (3 approval signatures) • Work Authorization Form (WAF) – this is approval for SLAC employee to work in installation site (8 approval signatures)

  14. Planning and Scheduling Daily tailgate meetings – reporting daily installation work activities Weekly integration meetings – intergroup status reporting Weekly installation meetings – integration engineers and MFD supervisors discussing technical installation issues Weekly MFD parts status meetings – discussing status and cost on open work orders Weekly procurement meetings – discuss open and future purchase orders Weekly meeting with Turner – planning six weeks look ahead schedule with Turner

  15. Integrated Schedule

  16. Schedule • LTU complete date • Magnet installation @95% (Davis Bacon) 6/24/08 • Install Vacuum components (SLAC-MFD) 9/15/08 • TDUND, Single Beam Dump & Zero Degree Shielding (Davis Bacon) 9/15/08 • Cable Installation (Davis Bacon) 9/09/08 • Check Out 10/30/08 • E-Dump • Complete stand installation (Davis Bacon) 7/07/08 • Complete magnet installation (Davis Bacon) 8/01/08 • Install Dump Shielding (Davis Bacon) 7/15/08 • Install Vacuum components/drifts (SLAC-MFD) 8/15/08 • Cable Installation (Davis Bacon) 11/5/08 • Check Out 12/31/08

  20. Summary • Progress towards completion of 2008 installation is going well in a safe working conditions • While waiting for beneficial occupancy we pre assembled components to the alignment stages and moved to staging area for installation • We are following the integrated schedule from Richard M. Boyce • There are still some installations challenges: • Co-occupancy with Turner constructions • Some components late into fabrication due to approval from RP • High rejection rates of copper plated drift tubes from supplier • E-Dump not yet fully accessible for installation
