17. 17 BROOKHAVEN SCIENCE ASSOCIATES Schedule Status Concrete Cylinder Break Test Results

18. 18 BROOKHAVEN SCIENCE ASSOCIATES Schedule Status Overall Project Status –16% complete (per cost basis) –Concrete Work on Schedule, recovered rain impacts in June & September –Underground Utility Work lagging due to Coordination Effort (required to resolve interferences See Drawing) –Fabrication of Structural Steel slightly behind early finish projections, but ahead of baseline.

19. 19 BROOKHAVEN SCIENCE ASSOCIATES Schedule Status Underground Utility Plan C – 600 Substantial Utility Installation Extensive coordination

20. 20 BROOKHAVEN SCIENCE ASSOCIATES Schedule Status Intermediate Project Milestones thru’ March 2010

21. 21 BROOKHAVEN SCIENCE ASSOCIATES Schedule Status Mandatory Project Milestone Report

22. 22 BROOKHAVEN SCIENCE ASSOCIATES Issues & Risks Potential Problems Winter Concrete Work –Winter Mix Design, Placement & Protection Plan Utility Installation in Inner Courtyard –Resolve Interferences (all resolved to date) –Coordination / Staging of Trades for Utility Work Potential for Construction Outpacing Design by ASD & XFD Groups –Could necessitate revision to installed work Coordination between LOB & Ring Building Contractors

23. 23 BROOKHAVEN SCIENCE ASSOCIATES Look Ahead Place Storage Ring Tunnel Floor Slab at Utility & Vehicle Tunnels –Allows backfill & continuity of Ring Storage Tunnel construction Construction of Underground Electric ductbanks Installation of Steam Main to Project Site Construct Selected Roadways & Parking Areas –Control site drainage, –Facilitates better soil erosion control

24. 24 BROOKHAVEN SCIENCE ASSOCIATES Conclusion Continue to encourage pace of construction At a safe rate Continue diligence of Inspections Advance Construction Operations with an eye to Minimizing Risks and Mitigating delays
