  1. Sector 20 Project Overview • Sector 20 Site Plan • Description • Schedule • Cost Estimate • Organizational Chart • Challenges • ES&H Issues • Progress to Date • Next Steps

  2. Site Plan Contractor Parking along gallery road (~10 vehicles) Traffic detour Sector 21 Klystron Gallery N

  3. Description • Demolition of existing 1700 ft2 Alcove Bldg. • Construction of new 2250 ft2 Bldg. in ~ same location with 10’ extensions on ends. • Laser Room to be Class 100,000 equivalent cleanroom, with certain materials (ceiling tiles, finishes) to be typical of Class 10,000 cleanrooms. • Construction of new 300 ft2 “RF Hut” in Klystron Gallery with Temperature Control ± ½ degree F • Some cable trays and supports (to support 35 lbs/linear foot). Surface mounted electrical distribution in injector alcove area. • Electrical Equipment – New Substation K-10B, 1500 KVA, 12.47K V to 480 V, 3 phase delta/wye (separate subcontract,) • Feed from Substation K-10B (separate subcontract) • New 2000 Amp Motor Control Center (purchased by SLAC as LLP, installed by S20 general subcontractor) • Service for LCLS Sector 20 equipment only (not Sectors 21-30) • 5T crane to injector area below

  4. Excluded from S20 Conventional Facilities Project • No experimental equipment included in scope of this project. • No PPS, laser safety or radiation shielding in scope of this project. Cabling to be designed by SLAC and installed by subcontractors as separate project. • Some cable trays (which will be supported by future racks) will be designed by SLAC installed with cabling mentioned above.

  5. Sector 20 Installation (future) Klystron Gallery Elev 0’-0” North Linac tunnel Elev -35’-0” Sector 20 Laser Facility

  6. Floor Plan Load/ Lock HVAC Laser Bay Local control Klystron Gallery RF Hut

  7. RF Hut Layout Wave guide supports by others Racks to be reoriented for proper access (typ) Fan coil unit

  8. Schedule • Title 2 Construction Package Completed Feb. 22, 2005 • Bid and contract with general contractor • RFP issued March 22, 2005 • Bids due April 14, 2005 • Award May 9, 2005 • Construction • Kickoff onsite June 1, 2005 • Beneficial Occupancy April, 2006 • Electrical service not available until after accelerator downtime – fall 2005 (not yet scheduled)

  9. Current P3 Schedule

  10. Cost Estimate – 1.09.03.01 • Estimated Construction Cost - $1.495M • $1,095,000 construction this subcontract • $300,000 electrical equipment LLP separate subcontracts • $100,000 prep, including relocation of CEF pump facility • Contingency of 30% has been allocated to construction costs, 40% to SLAC in-house preparation tasks $1.495M Construction Cost Breakdown

  11. Organizational Chart • Sector 20 Facility • Eric Bong – Injector and Linac Systems Manager • David Dowell – System Physicist • Sasha Gilevich – Optical Engineer • Ron Akre – RF Systems Manager • Conventional Facilities • David Saenz – Conventional Facilities Manager • Jo Beth Folger – CF Project Engineer / CAM • Jim Welch – CF Systems Physicist • Jesse Saldivar – CF Technical Assistance • Anita Malahowski – Cost/Schedule • Richard Hislop – Construction Safety Manager • Bruce Patten – Purchasing Officer

  12. Challenges • Management • SLAC policy changes in the wake of 10/11/04 electrical accident are still being developed. • Cost/Schedule Risk • Cost estimate based on Jacobs estimate 2/23/05 – confirmation when bids are received from subcontractors. Bids due 4/14/05. • Schedule verification during bid process. We will specify desired schedule, but may receive comments. • Technical • Electrical Design • Plans Review process at various stages of design • Arc-Flash hazard analysis to be performed by SLAC Configuration Management Electrical Working Group

  13. ES&H Issues • Demolition activities • Asbestos sampling and analysis by SLAC ES&H– none detected. • Lead paint sampling and analysis by SLAC ES&H – low (non-hazardous) levels detected. No danger to workers, but debris will be handled by EH&S Waste Management. • BAAQMD permit process to be initiated after selection of contractor (ES&H in conjunction with project) • Construction activity hazards • Managed by SLAC trained UTR. Includes preparation of Pre-work Hazard Analysis and Job Hazard Analysis and Mitigation (JHAM). • Subcontractor will be required to staff project with a Construction Safety Professional • Radiation • Review of plans by Stan Mao, RPD, and his requests incorporated in design. • Hoisting/Rigging • Citizens’ Committee and/or Hoisting/Rigging inspector will review the Subcontractor’s Rigging Plan prior to work, and inspect equipment used by Subcontractor at SLAC

  14. Progress to Date • Title 2 Design package completed 2/22/05 • SLAC Reviews • 3/3/04 Plan Review – Initial Draft Drawings • 8/25/04 Plan Review – 50% Drawings and Basis of Design (BOD). Comments received and incorporated. • 11/04/04 Structural Peer Review. Comments received and incorporated. • 11/12/04 Plan Review – 100% Drawings, Specs and BOD. • 12/3/04 Earthquake Seismic Safety Committee Presentation – Approval Granted • 12/15/2004 Safety Overview Committee Presentation • 2/1/2005 Fire Safety Committee Presentation • 2/15/2005 Electrical Safety Committee Presentation • Request for Bids issued 3/22/05 • Pre-bid job walks held 3/24/05 and 3/31/05 (4 general contractors and over 55 subcontractor personnel attended job walk)

  15. Next Steps • Award of Construction Contract • Safe Construction Project
