Agenda

• Design Status• Site & Utilities• Ring Bldg Structural • Ring Building Architectural• Ring Building Mechanical

• Design Management Activities


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


Overall Floor Plan


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”


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


Assessment on Column/Footing Interaction

Explored the following Options:

1. Footing top @ 20” below mat bottom2. 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


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

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

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


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


RF Compressor Building Qualitative assessment completed

Quantitative assessment under study

Isolation joint


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)

• 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



• 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


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)


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


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
