Build to Cost Meeting: Goals, Agenda & New Directions Peter Wizinowich NGAO Team Meeting September 11-12, 2008

2 Presentation Sequence Goals of Meeting 1.First step in design to cost –Identify core science & Observatory requirements –Identify base NGAO system 2. Planning for Internal Review of Build to Cost concept –Identify concept review success criteria –Identify tasks & schedule leading up to review Agenda Build to Cost (B2C) –Directions & Guidelines from Directors –Implications –Concept review success criteria –Plan

3 New Directions & Guidelines $60M cost cap in then-year dollars –From start of system design through completion –Includes science instruments –Must include realistic contingency –Cap of $17.1M in Federal + Observatory funds ($4.7M committed) Reviews –NFIRAOS cost comparison report at Nov/08 SSC meeting To better understand the fidelity of the SDR costing –Internal review of build to cost concept –Report on internal review no later than Apr/08 SSC meeting

4 Implications of New Directions & Guidelines New work required to reduce costs to fit in $60M cap –NGAO estimate at SDR, plus SD phase, ~ $53M (then-year $) –Science instrument estimate at proposal ~ $27M (then-year $) –Need to provide a major breakthrough in science capability for $ Need Science Advisory Team New work required on science instruments –Cost cap requires NGAO project to integrate all costs & planning including instruments During PD phase, instrument program management will continue for instruments, but integrated with NGAO (moved under NGAO project management at the same level as WMKO, COO and UCO project management; see Fig. 1 of NGAO PD phase SEMP) This will be re-evaluated for future phases during PD phase –Need to develop at least system designs, preferably preliminary designs, & costs during the NGAO PD –Need to identify funds & people for this (none in WMKO FY09 plan) & determine impact on NGAO PD plan

5 Implications of New Directions & Guidelines Report/Reviews –NFIRAOS cost comparison already planned –Cancel phased implementation & descopes review Need something for PDR, but not for build to cost concept review –Need success criteria, & plan to prepare, for build to cost review Budget –Cost cap does not need to include funding contingency –Team expected to raise up to $12.4M through government proposals, plus support proposals to private foundations –Do we charge indirect costs to government funding? Could reduce cost cap unless indirect costs not included in cost cap or we can use this infrastructure money –Can we place long lead procurements after PDR? Impacts schedule & then-year dollars

6 Build to Cost Concept Review Success Criteria –We have a believable approach to producing an NGAO facility within the cost cap –We have dealt with contingency properly –We have made the proper science benefit choices Assumptions –We will use our SD cost estimate refined by the NFIRAOS cost comparison –Better cost estimates will be produced for the PDR

7 Draft B2C / Cost Comparison Schedule

8 Science Instruments “Management Path Forward” Need to identify: minimum NGAO facility including science instruments science instrument success criteria for PDR resources needed for PD phase funds to support PD phase instrument work personnel to support PD phase instrument work near-term instrument project plan PD phase instrument project plan Will need to include: supporting B2C process further development of cost estimates

9 Science Instruments “Path Forward” Priorities –Support PDR success Design and build to cost objectives Systems engineering goals Interface definitions –Move instrument designs forward Address most challenging design aspects Develop firm interface definitions with AO system Support other design activities Develop full plans for design and fabrication Initial Plan –Limited in scope due to funding uncertainty –Focused on “minimum” needs to support AO system design –Pragmatic, based on heritage designs and proven concepts –Takes advantage of design overlaps between imagers –Seeks to develop synergy for probe arms between TT and d-IFS

10 Summary Further discussion of meeting goals? 1.First step in design to cost –Identify core science & Observatory requirements –Identify base NGAO system 2. Planning for Internal Review of Build to Cost concept –Identify concept review success criteria –Identify tasks & schedule leading up to review Further discussion of cost guidelines or path forward? Let’s take this opportunity to brainstorm & identify a successful path forward. Agenda
