1. T. Kirk’s 4 Dec 04 letter to DOE Construction Cost - $11M+ –Beam line g-2 ring upgrades etc - $11M –Cost sharing with RSVP of AGS/Booster rehab – discussed but not specified Operations Cost - $9-10M+ –25 week single year cost - $9-10M –3 week engineering run costs – discussed but not specified

2. Variance with T. Kirk’s 4 Dec 04 letter to DOE Construction Cost: $26M today ($9M + $2M Inflector, Kirks letter) –Scope changes: +$4.1M Beam Line – fwd decay (was back decay w/1X FODO) with 4X FODO (-$2M) Contingency for new cryo plant + $2M New Kicker, EQuad Rebuild, Bldg 919 AC + $1M Equipment testing (some with beam) + $1M Project Office + $0.7M Universities (detectors/DAQ) + $1.4M –Revised cost estimates, inflation: (-$1M inflector, + $1M other) –Cost of AGS/Booster rehab: +$11.7M (no cost sharing) Operations Cost: $17M, 2 year base plan –Engineering/data run, one 12 week year - $6M (3 weeks in Kirk’s letter – no costs specified) –Data Runs, one 29 week year – $12M (Kirk’s letter $9-10M for 25 weeks) –Variance ~ consistent with Kirk’s letter

3. What is needed to baseline the costs (not included in construction cost estimate) 1.0 g-2 Ring/Building maintenance –1 man month to engineer an air conditioning system for bldg 919 1.1 V/V1 Beam Lines –1 man-months engineering –1 man-months physicist 1.2 Inflector (see Meng talk) –A quote from the Furukawa Company for superconductor 1.3 E Quads –Nothing new, defendable 1.8 Kicker –Nothing new, defendable 1.11 Cryogenics (to determine scope) –2 man-months engineering –1 man-month tech 1.12 Vacuum System –1 man-month engineering 1.14 Booster/AGS –0.5 man month engineering –0.5 man month physicist ES&H – review operation within present guidelines –1 man-month physicist –1 man month engineer Preparation of Cost Books, Resource Loaded Schedules, CD0-1 documents etc –4 man-months engineering –4 man--months physicist Summary –11 man-month engineering – 7 man-month physicist – 1 man-month tech Required Budget ~ $360K Calendar Time Required ~ 6-8 months
