Project Status Update

• John N. Galayda
• Director, Strategic Projects Division
• Director, LCLS Construction
• June 25, 2009

2
Construction gt93 complete
3
TEC (Line Item) Progress

  FY09 procurements

4

DOE (Level 2) Milestone Performance
29 June 09
Projected CD-4 date is driven by a planned
shutdown in early 2010
7
Risk Assessment

• Happily, many technical risks to the project may
  be retired
• Civil construction generic risks are pretty
  invariant right up to the end of the project.
• While less cost-to-go means less budget risk, the
  approach of CD-4 milestone means schedule risk
  becomes more significant

8
Alternate Strategy for Office Space

• Requires allocation of 3M contingency
• 22,000 GSF pre-engineered building
• Some technician set-up space on ground floor
• 25 enclosed offices
• LEEDS Gold certified
• Guaranteed Maximum Price (GMAX) contract
• Performance specification defines the deliverable
• Beneficial Occupancy mid-April 2010

Assessment Safety

• SLAC, ANL, LLNL had excellent safety performance
  from their workers
• Contractors managed by SLAC did well
• Difficulty communicating expectations to
  subcontractors through GC
• Situation improved as a result of contract
  enforcement and engagement of GC upper management
• Total Project Hours
• 2.14 M Hours worked
• DART Rate 1.03
• Subcontractors
• 594 K Hours worked
• DART Rate 3.03 (9 Incidents)
• TRC Rate 4.04 (3 Incidents)
• LCLS Collaboration
• 1,546 K Hours worked
• DART Rate 0.26 (2 Incidents)

DART Rate
Injury rates based on 200 K hours (100 man years)
of effort. DOE/SC Goal is a Reportable Case (TRC)
rate of lt 0.25 and a Days Away, Restricted, or
Transferred (DART) rate lt 0.65 per 100 FTEs.
No DARTs in past 15 months
