1. 1 BROOKHAVEN SCIENCE ASSOCIATES CFAC Review Marty Fallier NSLS-II Conventional Facilities Schedule Review December 13, 2006

2. 2 BROOKHAVEN SCIENCE ASSOCIATES Schedule Schedule for conventional facilities developed at detailed level for conceptual design Needed to develop confidence in schedule phasing and sequencing Needed to identify key interface points with accelerator & beamline installation Prepared based on input and discussions with: LIRO CM scheduling group Major national CM firm (Gilbane) Large local contractor (EW Howell) Consensus that logic, sequencing, phasing and durations are reasonable

3. 3 BROOKHAVEN SCIENCE ASSOCIATES Schedule cont ’ d Key schedule objective – Enable start of accelerator installation as early as possible CF is critical path until the main bldg spaces are turned over for accelerator installation Schedule is reviewed weekly with Project Ctrls, XFD & ASD groups as part of Schedule Task Force Mtgs Key dependencies: 1 st pentant ready for accelerator installation Control room ready for installation BO of Ring Bldg for beamline installation

4. 4 BROOKHAVEN SCIENCE ASSOCIATES Schedule Modifications Underway Recent funding profile guidance differs from the basis used for CDR schedule development Currently iterating different schedule scenarios based on revised funding profile Trying to minimize impact to overall schedule Trying to minimize cost impact due to stretch-out Evaluating which activities can be deferred with least impact We are not quite there yet but hope to have confidence in revised schedule impacts in mid-May

7. 7 BROOKHAVEN SCIENCE ASSOCIATES Detail Schedule Sample

8. 8 BROOKHAVEN SCIENCE ASSOCIATES Schedule - Design Design Activity duration Title I Design – 8 months (ACD + T-I duration) Title II Design – 11 months Not a generous length but is reasonable given the following: Title I A/E is the CDR A/E – they have a running start Substantial portion of Title II design is a duplication effort Pentant 1 &5 (BLOC/LINAC/RF) are unique design-will take focused effort! Pentants 2, 3 & 4 are nearly identical – design one right and duplicate Chilled water expansion is duplication of existing CCWF Phase I design Early confirmation and configuration management of technical design parameters affecting CF is key! Interface managers have been designated to assure this is done Accelerator lattice design frozen May 2nd

9. 9 BROOKHAVEN SCIENCE ASSOCIATES Schedule - Construction Construction Activities (CDR Funding Profile) Site Preparation early procurement – 6 months Main bldg contract bid & award – 6 months Main bldg contract duration - 39 months Chilled Water Plant Expansion – 24 months Electrical Utilities – 18 months Mechanical Utilities – 17 months LN2 system – 9 months

10. 10 BROOKHAVEN SCIENCE ASSOCIATES Schedule – Construction cont ’ d Analysis – Hi level view ( in FY06 $) At NSLS II site ~$120M in work over ~40 mos = $3M/mo At CFN $2.4M/mo but in 50ksf building footprint Footprint for NSLS II is ~300ksf – 6 times the space! As long as sequencing is correct, there is ample time to get this work done The space available and layout enables great flexibility in sequencing work so all trades are continuously productive APS Comparison – (escalated to 06 $) APS cost $260M over 63 mo = $4.1M/mo vs $3M/mo for NSLS II APS- 960ksf/63mo = 15ksf/mo vs 361ksf/40mo = 9ksf/mo NSLS II

11. 11 BROOKHAVEN SCIENCE ASSOCIATES Schedule Summary Current schedule provides confidence that scope can be done in scheduled time Critical path is identified Critical dependencies & Milestone List are identified Schedule risk areas identified and mitigation underway (LLP) Path Forward – Additional schedule development underway: Analysis of impacts due to funding profile changes Early assessment is 3-6 month impact but must verify Weekly Schedule Task Force meetings to maintain up-to-date dependency status and work toward optimization Will solicit input in schedule development from CM as part of constructability review
