LIGO-G M LIGO Laboratory9 Adv. LIGO Seismic Isolation (SEI) Costs All costs are in base year dollars (un-escalated) Production cost = $37,952K including 26% contingency Proposed construction cost = $37,952K – 1.7 x $667K direct labor incl. Indirect = $36,819 Labor costs are borne by LIGO operations funds Average hardware cost = $36,819/30 units = $1,227K each chamber

LIGO-G M LIGO Laboratory10 Adv. LIGO Seismic Isolation (SEI) Costs 98.6%

LIGO-G M LIGO Laboratory11 Adv. LIGO Seismic Isolation (SEI) Costs In-chamber mechanical fabrication50.3% Instruments19.5% Electronics14.7% Mechanics11.8% Assembly, align, calibrate, test3.1% Controls1.8%

LIGO-G M LIGO Laboratory12 Adv. LIGO Seismic Isolation (SEI) Costs 3 Interferometers (IFOs) x $6,363K = $19,089K for in- chamber Mechanical Fab Contracts

LIGO-G M LIGO Laboratory13 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-M ) * * Should have used $436K for HAM production unit cost in the cost book rather than the estimated ETF production unit cost of $429K
