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

2. 2 BROOKHAVEN SCIENCE ASSOCIATES 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. 3 BROOKHAVEN SCIENCE ASSOCIATES 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. 4 BROOKHAVEN SCIENCE ASSOCIATES 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. 5 BROOKHAVEN SCIENCE ASSOCIATES Summary Schedule

6. 6 BROOKHAVEN SCIENCE ASSOCIATES 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. 7 BROOKHAVEN SCIENCE ASSOCIATES 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: 1 st pentant ready for accelerator installation BO of Ring Bldg for beamline installation

9. 9 BROOKHAVEN SCIENCE ASSOCIATES Verification with Independent Schedule BNL Schedule Duration 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 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

10. 10 BROOKHAVEN SCIENCE ASSOCIATES 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. 11 BROOKHAVEN SCIENCE ASSOCIATES 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. 12 BROOKHAVEN SCIENCE ASSOCIATES 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
