Scope
Systems Description remain unchanged
Sector 20 Injector Facility – completed in May 2006
Magnetic Measurement Facility – completed in April 2006
Linac Improvements – to be completed in 07 shutdown
Beam Transport Hall – in process ~ 15% complete
Undulator Hall – in process ~ 5% complete
Front End Enclosure – in process 5% complete
Electron Beam Dump – in process ~ 5% complete
Near Experimental Hall – in process ~ 35% complete
X-Ray Transport & Diagnostics Tunnel – in process ~ 5% complete
Far Experimental Hall – in process ~ 10% complete
Lab infrastructure - design is imminent
Any changes made to the CF scope resulting from VE adjustments have
no impact the technical systems
Modifications to the scope are coordinated with the Integration
Management Team (CF direct liaison)
Scope is well defined and understood by LCLS and the CMGC

Beam Transport Hall –
227m long above grade
facility to transport the
electron beam through the
existing RSY
Undulator Hall – 170m long
underground tunnel housing
undulators and ancillary
equipment
Near Experimental Hall –
underground facility whose
primary function is to house 3
experimental hutches, prep
and shops
Far Experimental Hall –
underground single 46’
cavern to house 3
experimental hutches and
prep space
Electron Beam Dump –
40m long underground
facility used to separate the
electron and x-ray beams
Front End Enclosure – 40m
long underground facility to
house various diagnostic
equipment in support of the
photon beam
~100’ location of
tunneling to date in
access tunnel
X-Ray Transport &
Diagnostics Tunnel – 200m
long underground tunnel

Schedule
Original LCLS CF schedule indicated 28 months for the
entire scope (including the CLOC)
Approved schedule (Jan 07) from CMGC for Beam-Path
construction presented by TCCo and approved by LCLS
(Aug 06 – June 08) indicates 22 months plus 2-3 months
for close-out (as-builts, O&M manuals, etc)
Concerns have developed with significant negative float
being reported against Co-Occupancy milestones in
monthly schedules within the initial 90 days of approved
Baseline Schedule
LCLS has made several requests for recovery plan schedule
CMGC has suggested recovery options that are currently being
reviewed and analyzed
Beneficial Occupancy milestones are threatened

Summary
Scope and schedule for CF WBS is well
understood
Budget is closer to being fully defined
Construction activities in the field are
demonstrating activities in parallel, slight
gain to schedule
Overall construction schedule requires
immediate attention!!
