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

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
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
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
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)
Next Steps • Award of Construction Contract • Safe Construction Project
