NGAO Project: AO Budget AO Cost Estimate = $35 M $10 M • Estimation

NGAO Project: AO Budget AO Cost Estimate = $35 M $10 M • Estimation approach 1: Comparison to other systems • Gemini-S MCAO - $18 M in 03 dollars. • • Gemini-S GPI - $19 M + $6 M reserve • • Add $15 M for LGS & subtract $5 M for instrument $35 M TMT NFIRAOS - $25 for AO & $24 M for LGS • • Add $7 M for 2 additional lasers + 4% inflation $29 M Subtract $10 M for simpler system $39 M Estimation approach 2: Bottoms-up cost estimate Estimation methods agree 6

NGAO Project: Instrument Budget • Cost Estimate = $20 M $4 M for 1

NGAO Project: Instrument Budget • Cost Estimate = $20 M $4 M for 1 st three instruments Instrument ROM Cost Anchor Near-IR Imager $3 M G-S NIR imager ~ $3. 5 M + 1 vs 4 H 2 -RG Visible Imager $3 M LRIS-R upgrade ~ $1. 5 M; camera/filters $1 M; SW $0. 5 M Deployable NIR IFU $14 M TMT IRMOS ~$42 M for 10 IFU + AO; ~$1. 6 M/IFU for 6 Near-IR IFU $7 M OSIRIS ~$5. 5 M + new detector Visible IFU $4. 5 M OSIRIS without full cryo, 4 x 4 K deep depletion CCD, slicer Thermal NIR Imager $3 M Similar to NIR, smaller but more expensive detector 7

System Design: Objectives • • Establish design approach that meets the scientific & user

System Design: Objectives • • Establish design approach that meets the scientific & user requirements Establish discipline integrated engineering plan for the proposed design • • Understand technical risks, trade-offs, performance estimates, cost to completion Key deliverables • • Systems Requirements Document System Design Manual Systems Engineering Management Plan Systems Design Report 8

System Design: Project Schedule Plan based on delivery of 4 key documents Plan includes

System Design: Project Schedule Plan based on delivery of 4 key documents Plan includes schedule & person-hours 9

System Design: Project Schedule System requirements need science team effort • Budget includes 3

System Design: Project Schedule System requirements need science team effort • Budget includes 3 graduate students & 1 postdoc 10

System Design: Project Schedule System design will utilize expertise & resources at CIT, UC

System Design: Project Schedule System design will utilize expertise & resources at CIT, UC & WMKO 11

SD: Risk Assessment & Management • Detailed risk assessment spreadsheet produced • • ~40

SD: Risk Assessment & Management • Detailed risk assessment spreadsheet produced • • ~40 items identified during initial point design development Severity & probability of each item indicated along with risk mitigation plan During system design each risk area will be further addressed as either part of the planned trade studies &/or as part of risk assessment Risk management process includes balancing scientific & technical performance, cost & schedule 13

System Design: Budget Cost Estimate = $980 k • Basis: • • • 12400

System Design: Budget Cost Estimate = $980 k • Basis: • • • 12400 hrs or 6. 4 FTE eng/scientist * $120 k/yr = $770 k 5500 hrs for 3 grad students + postdoc = $150 k $40 k for travel + $20 k for procurements • Only 3% of total NGAO budget system design phase budget may be low • Believe we have properly identified path forward & have a clear idea of how to proceed A more detailed estimate will be prepared as individuals identified & next level of detail added to plan • 14

Management Status • • • Observatory Directors plan to define the NGAO management structure

Management Status • • • Observatory Directors plan to define the NGAO management structure More detailed NGAO system design phase planning awaits management structure resolution NGAO ready to become a real project 15

NGAO Project: Next Steps NGAO is ready to become a real project: • Ready

NGAO Project: Next Steps NGAO is ready to become a real project: • Ready to begin system design phase • The project needs the following key personnel: • • • NGAO Project Scientist & science team lead development & iteration of science requirements • • • Principal Investigator Project Scientist + Science Team Project Manager Systems Engineer Volunteer model unsustainable Need to take advantage of expertise & resources at CIT, UC & WMKO in system design Form NGAO Science Advisory Committee to provide high level science guidance 16
