LAT Fabrication Project at a Glance
• Cost
– Total project cost (funding, 3/31/03): $121.7M
– Baseline (5/31/02): $100.0M budget at completion, $21.2M
contingency
– Cost status (3/31/03): $45.4M spent, $107.5M budget at completion
– $14.2M contingency available (24% of $59.4M cost-at-risk)
• Schedule
– LAT delivery scheduled for 9/22/05
• Defined by acceptance of flight-ready LAT by GLAST Project
Office for integration with spacecraft (triggers DOE CD-4)
– Critical path analysis includes 17 weeks float to ship date
• Full description of LAT project loaded into Project
Management Control System (PMCS)
– Resource-loaded schedule is under configuration control, and
being tracked

Expenditures since baseline established (5/31/03): $20.2M
Earned value since baseline: $21.0M
Cost variance: $0.7M favorable
Contingency allocated since baseline: $7.0M
Remaining contingency 24% on costs at risk
• Schedule status 3/31/03
– Development and manpower issues, delayed flight parts
procurements have contributed to $3.4M (~4 weeks) unfavorable
schedule variance since baseline schedule established
– Expect to recover variance by end of FY03
– Critical path maintains 17 weeks float to ship date (unchanged
