Schedule Project Schedule includes three major phases RD

Schedule • Project Schedule includes three major phases: — R&D Phase: begins in FY 09 and continues to Q 1 -FY 11 — Construction Phase: begins in Q 2 -FY 11 (CD-0) and continues to Q 4 - FY 14 (CD-4) — Operations Phase: 6 years of instrument operations with data analysis followed by an 18 month period after telescope operations have ceased for the completion of the data analysis • 2 year R&D Phase, includes: — Telescope optics design refined and optimized — Prototype of 3 -arm spectrograph fabricated and tested — Fiber positioner prototype further tested and optimized

Cost Summary • Total Project Cost was estimated with a grass-roots estimate using quotes and labor estimates from similar systems — BOSS spectrograph upgrade — WFMOS spectrograph proposal — Vendor quotes for Detectors (e 2 v and Teledyne) • Cost breakdown in FY 09 $M, assuming current LBNL labor rates: Contingency accounts for the reserve held for the construction phase and is distributed by element, based on the maturity of the item
