Conventional Facilities CONSTRUCTION PROGRESS AND ESTIMATE TO COMPLETE METHODOLOGY

Conventional Facilities Project Office efforts to minimize impact of Continuing Resolution on Conventional Facilities Continued full funding of construction contracts Increased staff to support construction schedule Maintained construction schedule for Early and Beneficial Occupancy of conventional facilities

Conventional Facilities Impacts of Continuing Resolution Scope Build-out of Far Experimental Hall hutches shifted to later years Build-out of existing Lab Office space shifted to later years Staff CF Support for build-out and Technical Systems installation shifted to later years

ETC Methodology Reviewed Work Breakdown Structure Re-evaluated Resource Loaded Schedule Adjust Key Cost and Schedule Assumptions Validate Funding Profile Review Critical Path Update Risk Management Develop Cost-to-go (Estimate to Complete)

Work Remaining (from July 07 ETC) = $73M Contingency Analysis Work Remaining (from July 07 ETC) = $73M Total estimated contingency = $6.5M (9%) Estimated contingency for FY08 only = $3.7M

Critical Milestones BTH – NEH Co-Avail (20DEC07) XRT- FEH Co-Avail (21MAR08) Beneficial Occupancy Dates support CD-4 (July 2010)

Critical Path Reasonably defined thru CD4 CF Milestones support overall project Level 1 and Level 2 Milestones Critical Path through Central Utility Plant for start-up at NEH Critical Path through Far Experimental Hall for CD-4 Reflects an integrated schedule The integrated schedule includes Co-Avail and Beneficial Occupancy dates for starting technical system installation Are durations reasonable CF Baseline Schedule includes durations by the Trade contractors and approved by LCLS Consistent with Funding profile, start-up test plan, acquisition strategy, available resources Project strategy to complete conventional construction forces the funding profile to be consistent with construction demand Assess float All critical activities are zero float (latest schedule recovery plan)

CF Completed Level 3 Milestones

Schedule – Level 3 Milestones

Risk Management Protect in-place Utilities Contractor Claim $100K (Mitigate) Protection for unknown existing utilities Contractor Claim $2.4M (Mitigate) In negotiations – appears likely to settle for less than claimed amount Affholder default due to liquidation $250K (Accept) Performance Bond used to complete work Far Experimental Hall Hutches $1.0M (Mitigate) Design of hutches proceeds during FY09 Construction Stand-down $2.75M (Mitigate) Laboratory-wide stand down due to safety

Conventional Facilities Summary Minimal Impacts from Continuing Resolution Delayed build-out of Far Experimental Hall Increased Project Staff costs Overall Estimate to Complete increase = $3.9M Early and Beneficial Occupancy preserved. Outlook for meeting CD-4 is good. Risks going forward are minimal
