  1. Conventional Facilities Schedule Steve Sawch Asst. Director, Construction Management CF Advisory Committee Review of the NSLS-II Project May 8, 2008

  2. CF Schedule Outline • Schedule Parameters • Schedule Risk Reduction • Summary Schedule • Schedule Durations • Intermediate Milestone Challenge • Verification with Independent CPM Schedule • Schedule Analysis • WBS Update • Schedule Summary

  3. Schedule Parameters • Schedule for conventional facilities developed at detailed level • Needed to meet critical milestones • Needed to meet project funding • Needed to develop confidence in schedule phasing and sequencing • Needed to identify key interface points with accelerator & beamline installation • Needed to develop baseline schedule • Prepared based on input and discussions with: • LIRO/Gilbane CM scheduling group • Large local contractors • Consensus that logic, sequencing, phasing and durations are reasonable

  4. Schedule Risk Reduction • Early procurement • Site-prep reduces schedule and cost risk and overall duration • Takes risky earthwork (unforeseen existing conditions) off the critical path • Delays due to “getting out of the ground” are frequent source of claims • Perform environmental testing and remediation (if required) • Decommission/relocate existing utilities • Early procurement of chilled water equipment • Chillers • Cooling Towers • Early procurement of electrical equipment • Main substation • Switchgear

  5. Summary Schedule

  6. Schedule - Durations • Construction Activities • Site preparation contract duration – 4 months • Main bldg contract bid & award – 5 months • Ring bldg contract duration – 36 months (excluding LOBs) • Entire bldg contract duration - 48 months • Chilled Water Plant Expansion – 28 months • Electrical Utilities – 18 months • Mechanical Utilities – 22 months • LN2 system – 9 months

  7. Critical Intermediate Milestones • Key schedule objective – Enable start of accelerator installation March 2011 • CF is on or near critical path until the main bldg spaces are turned over for accelerator installation • Schedule was interfaced with Accelerator and EXP. Facilities groups to identify necessary and workable dependencies • Key dependencies: • 1st pentant ready for accelerator installation • BO of Ring Bldg for beamline installation

  8. Pentant 1 Detailed Schedule

  9. Verification with Independent Schedule BNL Schedule Duration Liro/Gilbane Schedule Duration Pentant 1 – 21 months Pentant 5 – 21 months Pentant 2 – 20 months Pentant 3 – 20 months Pentant 4 – 19 months Injection Bldg. – 18 months RF Bldg. – 16 months Overall – 41 months • Pentant 1 – 20 months • Pentant 5 – 20 months • Pentant 2 – 21 months • Pentant 3 – 24 months • Pentant 4 – 24 months • Injection Bldg. – 26 months • RF Bldg. – 21 months • Overall – 48 months

  10. Schedule Analysis • Analysis • At NSLS II site ~$180M in work over ~48 mos = $3.75M/mo • At CFN $2.4M/mo but in 50ksf building footprint • Footprint for NSLS II is ~400ksf – 8 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 today's $) • APS cost $275M over 63 mo = $4.4M/mo vs $3.75M/mo for NSLS II • APS- 960ksf/63mo = 15ksf/mo vs 400ksf/48mo = 8.3ksf/mo NSLS II

  11. WBS Update • Currently Updating WBS • Construction Phase CM Deleted • LOBs Design Deferred • LOBs Separate Contract • Chilled Water Plant and Piping Separate Contracts • Simplify and Standardize • Use CSI Codes – Divisions 1-16 – map to estimates • GC to Develop Their Own Schedule • Establish GC Interface • Evaluate Performance- EVMS

  12. Schedule Summary • Schedule provides confidence that scope can be done in scheduled time • Critical path is identified • Critical dependencies are identified • Schedule risk areas identified and mitigation underway (early procurement) • Path Forward – Additional schedule development underway: • Ongoing Scheduling Updates • Input from CM during Pre-Construction • Contractor Outreach • More detailed resource loading of activities in CSI format
