1. Cost Estimate • New Cost Estimate • Manpower Costs (Op. SWF) • Equipment Costs (Eq. M&S) • Contingency • Conclusions Mike Tuts DOE Review June 6, 2000

2. Re-evaluating Cost Estimate • Elements of the cost estimate • Manpower • Technical manpower costs are those assigned to D0 • We estimate contingency of ~50% on our estimates for FY00-01 • Equipment • Accepted the prior year costs (<FY00) in lab books • Concentrated on bottoms up estimate to complete • Contingency • Based on present experience, assigned larger than “normal” contingencies to assure fiscal success

3. Manpower • Track actual manpower by effort reporting at WBS level 2 (data available from 1/98) • by type, eg MT, ME, ET, EE • by subsystem • Extract manpower profiles from MS Project • Based on schedule as of end 99 • Have observed that effort reported manpower larger than from schedule • Schedule delays => greatly underestimated in the outyears relative to baseline • Use effort reported manpower to estimate Operating SWF costs

4. Manpower (Op SWF) • Effort reported Fermilab FTE by type • Converted to then yr k$ using average salaries (Op SWF) • Change request submitted & approved by Lab 3/20/00 * Estimated + Including contingency

5. Equipment (M&S) Cost Estimate • Performed new bottoms-up cost estimate to complete in Feb-March 2000 • Provided by subsystem managers • Clear we would exceed the baseline cost • Recall “uncomfortably” low contingency at last review • Change request to Lab • Include FY99 and before as in lab books • Accept Lab figures for 92-93 (+$479k) • Review of ETC by John Cooper + 20 reviewers! March 15,16,21 • Reduce cost by $130k, raise contingency by $675k • D0 response to further raise contingency by $200k for management contingency based on recent experience to further assure success • Change request approved by Lab and submitted to DOE • Approved by DOE on 4/24/00

6. M&S Cost Estimate • Estimate to complete through April 2000 • provided by Level 3 managers • M&S only, then year k$, incl. $70k contingency • EAC= estimate at completion, ETC = estimate to complete (based on obligations through April)

7. Cost Variance • Variances from Nov 99 DOE review (then yr k$) • PMP 6/98 baseline for reference (*=FY95 x 1.06)

8. Contingency Analysis • Risk based analysis (Then Yr $) • Initial subsystem & project managers estimate • $528k + $200k (management) • Cooper committee adjusted • +$715k • Project managers adjusted for management contingency • +$200k • Used $71k of this contingency to date

9. M&S Cost Change Request • Based on prior obligations, new ETC, contingency analysis, and review (Then Yr $) – as of March 2000 • Change request (1-032400-01) approved by DOE on 4/24/00 • Did not realize $1.5M of non-DOE funds originally anticipated • Cost increased by $1.5M (-$250k Plant) • Estimate $1.6M of contingency Actual: $282k

10. Contingency use • Contingency now held by Lab (Deputy Director) & DOE Project manager • Have implemented change control to request contingency • Total $71k to date • Near future: • Silicon ~$100k • Shop charges, mechanical infrastructure, installation • Muon trigger ~$50k • Additional cards, engineering

11. Funding Summary • Based on Lab spreadsheet • In Then Yr k$, and FY95 k$ • Includes all contingency in FY2001 • Includes: all approved changes (M&S, Op SWF, G&A)

12. Obligation Profile • Based on input from subsystem managers • No contingency included • Forward funding • $1M Stony Brook -in place • $0.8M Michigan State – in process

13. FY00 Funding • Given profile, do we have sufficient obligation authority this FY to move ahead? • Obligated the present (FY00) budget amount $2.8M • Conclude that we may need $0.5-1M in additional forward funding (have prospects) • We can defer some of the obligations (~$300k)

14. Conclusions • Costs and contingency recently reviewed • Change to TEC implemented through DOE change control • Contingency use monitored & controlled more closely • Will need additional forward funding this FY (~$500k-$1M) • We believe that the funding (with contingency) is adequate to complete the project
