6. 6 BROOKHAVEN SCIENCE ASSOCIATES RING SLAB Thickness Optimization ( to 27 ” ) Service Building Slab Elevation Effect of slab thickness in 4-50 Hz range: 39 ”  2.62 nm 33 ”  2.85 nm 30 ”  2.97 nm 27 ”  3.00 nm

7. 7 BROOKHAVEN SCIENCE ASSOCIATES Assessment on Column/Footing Interaction Explored the following Options: 1. Footing top @ 20” below mat bottom 2. Footing top @ 36” 3. Footing top @ 72” 4. Footing bottom flush with mat bottom Recommendation: DESIGN with 20-inch separation between bottom of ring slab and top of footing

8. 8 BROOKHAVEN SCIENCE ASSOCIATES Detailed Models used in optimizing column footing depth Optimization was based on: Wind Loads and Vibration Transmission

9. 9 BROOKHAVEN SCIENCE ASSOCIATES Detailed Models used in optimizing column footing depth

10. 10 BROOKHAVEN SCIENCE ASSOCIATES Detailed Models used in optimizing column footing depth

11. 11 BROOKHAVEN SCIENCE ASSOCIATES Architectural Design Revisions. LOB design program deferred to 2010 Provide Toilet cores if LOB not constructed Provide all future utility connections to LOB in Ring Building Design for possible two stories Design to accommodate future access corridor Aligned Service Buildings with center of LOB ’ s Rotated lattice 22.5 º clockwise Long Beam lines Added lowered exterior access corridor Stairs, Mechanical and ADA lifts between long beam lines

12. 12 BROOKHAVEN SCIENCE ASSOCIATES By-pass Corridor Extended Experimental Floor Std Access Corridor Stair, ADA Lift and Material Lift Ramp

13. 13 BROOKHAVEN SCIENCE ASSOCIATES Elevation Through Corridor At Beamline 2 ’ -6 ” 7 ’ -1 ”

14. 14 BROOKHAVEN SCIENCE ASSOCIATES Elevation Through Corridor Between Beamlines

15. 15 BROOKHAVEN SCIENCE ASSOCIATES Architectural Design Revisions Cont. Service Building Eliminated super doors Reconfigured entrance labyrinth to Storage Ring Provide removable shielding blocks to Storage Ring Eliminated Elevator and provided crane access to second floor Provided elevated slab on ground level to reduce vibration Operation Center Relocated control room to existing NSLS Computer Room, telephone /data and UPS rooms remain Future 3 rd floor offices relocated to near front entrance as future alternate design

16. 16 BROOKHAVEN SCIENCE ASSOCIATES Architectural Design Revisions Cont. Booster Building Provided mezzanine to accommodate HVAC units and DI Water Systems Revised labyrinth for tunnel entry Revised injection transport region RF Building Expanded one bay to accommodate future RF cavities Expanded mezzanine level to accommodate equipment/Control Room Finalizing Compressor Building, Helium yard, and Liquid Nitrogen supplementary tank

17. 17 BROOKHAVEN SCIENCE ASSOCIATES RF Compressor Building Qualitative assessment completed Quantitative assessment under study Isolation joint

18. 18 BROOKHAVEN SCIENCE ASSOCIATES Mechanical Design Revisions Cont. Fire Protection Developed Fire Protection strategy for the Experimental Hall to receive waiver of $150,000,000 max loss potential limitation Eliminated separation walls in Experimental Hall Requested waiver for two hour separation between Experimental Hall and LOB ’ s and Service Bldgs in lieu of 3hr Waiver approved but required additional redundancy for water supply, sprinklers and HSSD throughout Process Utility Loads Was a moving target however it is now finalized (final rev)

20. 20 BROOKHAVEN SCIENCE ASSOCIATES Mechanical Design Revisions Cont. Storage Ring Tunnel Added return air ductwork to assure temperature stability and meet smoke evacuation requirements Temperature Stability modeling of the tunnel relative to earth berm and Experimental hall has been performed and determined to be within design parameters Experimental Hall Relaxed temperature stability to +/- 1 C - eliminated VAV boxes Able to reduce beamline utility services by utilizing some services from storage ring tunnel (GN2, DI PCW) Distributed return air to accommodate fire smoke exhaust

21. 21 BROOKHAVEN SCIENCE ASSOCIATES Mechanical Design Revisions Cont. Process Water Systems Revised from de-centralized system to centralized system Centralized system located in Cooling Tower pump building DI water system will be primary-secondary piping arrangement

22. 22 BROOKHAVEN SCIENCE ASSOCIATES Title II Design Management Changes to design have used up available float for T-II HDR agreed to maintain design delivery date of 8/25 Required change to intermediate milestones LOB design deferred to 2010 Beamline support requirements will be better defined A/E can focus on Ring Building design Scope is frozen, only changes essential to Key Performance Parameters A/E using added resources from other offices Floor plans set, & all utility & process loads finalized (final rev)

23. 23 BROOKHAVEN SCIENCE ASSOCIATES Title II Design Management cont ’ d Additional Design Scope HDR is designing Central DI Process Cooling Water Plant Scope transferred from ASD Integrates tower water and DI PCW – long term operational savings A/E Design to Cost Clause Changes to scope/cost are being assessed and will be incorporated in revised Design to Cost Target for A/E A/E still accountable for construction budget and to perform V/E Issue is complicated by influence of volatile market and role of independent estimate provided by CM

24. 24 BROOKHAVEN SCIENCE ASSOCIATES Ring Building Package Scope Ring Bldg Package Base Bid Ring building w/ all site utilities but w/o LOBs Beamline utilities to 60% of Ring Exterior long beamline access corridor at LOB1-2 Add Alternates Extend Beamline Utilities remaining two pentants Redundant Electrical Feed.
