  1. CFAC Review Marty Fallier NSLS-IIConventional Facilities Schedule Review December 13, 2006

  2. 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. 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: • 1st pentant ready for accelerator installation • Control room ready for installation • BO of Ring Bldg for beamline installation

  4. 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

  6. Integrated Summary Schedule (Constrained Profile)

  7. Detail Schedule Sample

  8. 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. 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. 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. 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
