Outline • Review current budget status • Discuss construction budget, schedule and related items

Current Status • OSU design contract started Dec. 1, 2009 • NOAO had 3 main budget components • Initial preparatory phase (Aug until Dec. 1, 2009) • Design phase science activities (non-ReSTAR) • Design phase ReSTAR effort

Current Status • OSU will have largely spent funds by end of this month (Aug), as planned ($241K) • Final invoice after completion of design review

Current Status • NOAO expenditures recorded through June 30: • Initial preparatory phase spent $40K • Design phase science activities spent $4K out of $31K budget • Design phase ReSTAR effort spent $46K of $145K budget • Expenditures in July/Aug will be substantial (but not $100K)

Current Status • Why did NOAO over-estimate expenditures? • Science effort low because project scientist position became vacant, individuals “helping out” generally did not charge • Over-estimated required commitment for project management generally • Guess is that final expenditures will be somewhat over 50% of budget • This experience is folded into estimates that follow

KOSMOS Construction Budget & Schedule • Process: • OSU built up a master plan based on remaining design effort and experience with OSMOS I&T • NOAO did a more detailed estimate (given lack of experience with OSMOS) and verified schedule was consistent with OSU plan • Both effectively a bottom-up estimate starting at level 2 or 3 of WBS • Won’t discuss details unless requested, see references

KOSMOS Construction Budget & Schedule • Process: • OSU contingency estimated for major procurement categories and for manpower at relevant parts of schedule (hence, both budget and schedule contingency) • NOAO used “risk factor” approach (cf. ALMA, TMT, etc.) at the task level, roll up into pool. Associated schedule contingency consistent with OSU plan

Budget Summary

Contingency • Rolled up at the institutional level • Easier to manage than if done at project level • Overall just under 15% of baseline costs – plausible given nature of project • We expect to spend it – properly estimated, that’s what it’s for

Budget Summary by WBS • Some remarks: • Because of granular budgeting at OSU (and standard university policies for faculty salaries), OSU costs concentrated in a few elements • Some WBS elements are more separate than others – e.g., 6 & 10 linked

Total Cost • Including construction phase budget and anticipated expenditures for design phase, total instrument cost will be just under $2.1M

Schedule • Detailed schedule available on-line (on-wall) • Most major tasks flow independently into I&T phase • Mechanical design and fab is the main exception • Interaction between spectrograph control software and top-level software

Schedule • Schedule looked at NOAO labor loading • Mechanical fabrication and software efforts near 100% but not over for a few months • Need to coordinate with ODI • Other tasks under 100% loading for people involved • OSU schedule is built up using available staff at 100% when needed

Mechanical Design & Fab • Example of flow of work for enclosure • Instrument electronics box drawings available early and needed early; fabrication occurs Sept/Oct • Main enclosure drawings need redesign but enclosure not needed until end of March ‘11 (misc parts needed later); design and fab phased accordingly

Flow of I&T through Acceptance Note arrival of enclosure end of March, optics end of May
