  1. CFAC Review – Title II Design Status Ove Dyling Assistant Director for Design Conventional Facilities NSLS-II Conventional Facilities Title II Design Status May 8, 2008

  2. Agenda • Design Status • Site & Utilities • Ring Bldg Structural • Ring Building Architectural • Ring Building Mechanical • Design Management Activities

  3. Site & Utilities Design Revisions • Finished Floor Elevation • CD2 Finish Floor Elevation 70’-0” • Present Finish Floor Elevation 74’-0” • Process DI Water System • Relocated Cooling Tower to inside ring • CD2 design de-centralized distribution system • Present design centralized distribution system • Enlarged Cooling Tower Pump Building • Geotechnical • CD2 exploration program • Completed 16 borings • Present exploration program • Completed 75 additional borings

  4. Overall Floor Plan

  5. Ring Building Structural Design Revisions. • Expanded Steel width from 67’-0” to 77’-0” • Optimized concrete slab thickness • Experimental Hall from 18” to 15” • Storage Ring floor from 33” to 27” • Lowered finish floor elevation in storage ring • CD2 1’-4” above Experimental Hall • Presently 8” above Experimental Hall • Finalized top of building steel footing foundation below Storage Ring slab at 20”

  6. 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. Assessment on Column/Footing Interaction Explored the following Options: Footing top @ 20” below mat bottom Footing top @ 36” Footing top @ 72” Footing bottom flush with mat bottom Recommendation: DESIGN with 20-inch separation between bottom of ring slab and top of footing

  8. Detailed Models used in optimizing column footing depthOptimization was based on: Wind Loads and Vibration Transmission

  9. Detailed Models used in optimizing column footing depth

  10. Detailed Models used in optimizing column footing depth

  11. 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. Std Access Corridor By-pass Corridor Extended Experimental Floor Stair, ADA Lift and Material Lift Ramp

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

  14. Elevation Through Corridor Between Beamlines

  15. 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 3rd floor offices relocated to near front entrance as future alternate design

  16. 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. RF Compressor Building Qualitative assessment completedQuantitative assessment under study Isolation joint

  18. 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)

Loads Al ~ 1 MW transfers with electron beam Stays in SR RF in an upset condition

  20. 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. 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. 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. 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. 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. • Shield Doors at all Ratchet Wall openings. • Clearstory windows at Ring Building. • Exterior wall panels at LOB (needed only if LOB not built) • Exterior access corridor LOB 2-3 • Exterior access corridor LOB 3-4 • LOB Package • 2 full LOBs, one shelled LOB • Lavatories and wall closure as needed for complete bldg
