2. LIGO-G030289-00-M LIGO Laboratory2 Adv. LIGO Program Management (FAC) Scope Conversion of the 2km vacuum system to 4 km »Move the mid-station BSC chamber to the end station connected to the existing BSC chamber with a spool piece »Install a vacuum spool piece (pipe) in the mid-station where the BSC chamber previously resided Portable Clean Rooms »Build more HAM and BSC units to support more parallel installation activity and to support SEI and SUS clean assembly; for each observatory: –2 BSC-size clean rooms for high bay assembly area for SEI and SUS –2 BSC-size clean rooms in the corner LVEA and 1 per end-station VEA for SEI/SUS integration for “cartridge” installation into chambers –1 additional HAM-size clean room for parallel installation of input and output optics –And 2 additional BSC-size clean rooms for LHO to eliminate need for clean rooms to pass from one IFO to the other and to support parallel installation preparation Input/Output Mode Cleaner Tube Replacement & Bake-out »Larger diameter vacuum tubes are needed for the input & output sections »Tubes must be vacuum baked (perhaps stand-alone)

3. LIGO-G030289-00-M LIGO Laboratory3 Larger Diameter Mode (MC) Cleaner Tubes Larger diameter tube Possibly larger diameter tube

4. LIGO-G030289-00-M LIGO Laboratory4 Adv. LIGO Program Management (FAC) Schedule Procurement/contracting for the FAC equipment is not schedule critical (lots of float) Installation of the IO vacuum tubes occurs during installation activities

5. LIGO-G030289-00-M LIGO Laboratory5 FAC Costs All costs are in base year dollars (un-escalated) Total cost = $4,182K including 22% contingency Proposed construction cost = $4,182K – 1.7 x $198K direct labor incl. indirect = $3,845K Direct labor costs are borne by LIGO operations funds

6. LIGO-G030289-00-M LIGO Laboratory6 FAC Costs: 2km to 4km Conversion 2km to 4km conversion estimate based on initial LIGO experience Planned as a subcontract ($370K) with Lab oversight/management

7. LIGO-G030289-00-M LIGO Laboratory7 FAC Costs: Clean rooms Costs based on initial LIGO actual costs for clean rooms, escalated to base year dollars Includes estimate for in-house labor to place and oversee the clean room fabrication contract $1,032K IFO1 + $747K IFO2 = $1,779K total

8. LIGO-G030289-00-M LIGO Laboratory8 FAC Costs: I/O Tubes $651K IFO1 + $585K IFO2 + $585K IFO3 = $1,821K total
