  fabrication) in Sep2003 -- likely 2 awards
• Hiatus during LASTI SEI subsystem testing before
  production phase (phase 3)

  prototype testing at LASTI
• Production and procurement of long lead items
  initiated after PDR
• Final Design Review (FDR) held Nov 2005

Adv. LIGO Seismic Isolation (SEI)In-Chamber
Mechanical Fab. Costs

• In-chamber mechanical fabrication contract unit
  costs are based on an analysis of the actual ETF
  technology demonstrator costs (LIGO-M030024-02)

Should have used 436K for HAM production unit
cost in the cost book rather than the estimated
ETF production unit cost of 429K
