Building Program 5 BROOKHAVEN SCIENCE

Experimental Floor Concept • Divided into 5 clusters • Service Bldg supports all services within the cluster • Six sectors/Cluster • CLOB & Service Bldgs contain all Accelerator systems • Ring, CLOB, LOB 1 & service bldgs are base scope • LOB’s 2, 3, 4 can be added as needed w/o interruption 6 BROOKHAVEN SCIENCE

Experimental Floor Arrangement 7 BROOKHAVEN SCIENCE

Experimental Floor - Ring Building Section 8 BROOKHAVEN SCIENCE

CLOB Features • Space for 190 Offices, 8 labs • Nominally 30 User Offices, 5 User labs from the total • Possible 400 seat Conference Center addition w/ vendor area and three breakout rooms • Lobby and User Reception area • 2 nd floor viewing gallery overlooking experimental floor • Bridge to electrical mezzanine and control room & RF/LINAC areas • Close Proximity to future: • JPSI Building • Guest house 9 BROOKHAVEN SCIENCE

Floor Plan – CLOB 3 rd 12 BROOKHAVEN SCIENCE

LOB Features • Modular design – can be added when needed • without interrupting operation 11, 000 SF each – Serves six sectors • 30 offices w/ conference space, interaction areas, lavs, showers • 5 labs intended for shared use • Shipping/Receiving/Storage area & chemical storage area • Potential for expansion for more offices if needed • Egress provided for personnel and large items at each LOB • Loading area with exterior roll-up door • Roll-up door from each lab onto the experimental floor 13 BROOKHAVEN SCIENCE

Lab – Office Building 14 BROOKHAVEN SCIENCE

Differential Settlement • Measures to reduce potential for differential settlement include: • Thorough geotechnical analysis of site to identify problem areas • Minimize footprint over disturbed areas • Set finished floor elevation for maximum cut and minimum fill • Early site preparation contract for maximum time to cut, fill, compact and observe settlement prior to building contract. • Monolithic slab design for tunnel and experimental floor • High slab stiffness, Tunnel 36”; Experimental Floor 18” 15 • Building loads isolated from tunnel and experimental BROOKHAVEN SCIENCE

Vibration Mitigation • Measures to be implemented in conventional design include: • “Monolithic” slab for accelerator and experimental floor • Slab thickness and section changes will be based on vibration modeling results • Possible use of polymer admixtures for enhanced damping characteristics – likely use for access corridor • Isolation of bldg structure from tunnel and slab • Inertial bases and isolation of machinery • Low flow velocity design for ducts and piping • Limited use of duct and piping isolation to avoid conversion & transmission of low frequency vibration • Commissioning of equipment and systems to include alignment, balancing & 16 vibration measurement BROOKHAVEN SCIENCE

Utility Support • Utilities run underground in center of ring and distributed to five service bldgs (one in CLOB RF/LINAC area) • Minimizes pipe runs and pipe size in bldg proper • Only needed service piping will be run in experimental area • Minimizes potential noise and vibration impacts • Services provided at each BL include: • Electric Power Panel at Ratchet Wall, 75 -95 k. W/Cell, 120/208 V • Cooling Water, HVAC Supply Air, Exhaust • Compressed Air, LN 2, GN 2 • DI Water (Copper and Aluminum) by Accelerator Group 17 BROOKHAVEN SCIENCE

Utility Support 18 BROOKHAVEN SCIENCE

Temperature Stability • Key temperature stability requirement is tunnel air @ +/- 0. 1 C at a given location with respect to time. • Requires high resolution industrial grade instruments and controls with excellent repeatability. • Space temp setpoint of 85 F is nominally equivalent to process cooling water supply setpoint to minimize temperature gradients • Should be readily achievable provided loads to accelerator components are relatively steady-state • Experimental Floor Temperature • Cooling: 75 F +/- 1 F, 50% RH +/- 10% RH • Heating: 75 F +/- 1 F, 30% RH +/- 10% RH 19 BROOKHAVEN SCIENCE

Experimental Floor Air Distribution 20 BROOKHAVEN SCIENCE

Schedule • Construction sequencing will enable • Availability of Ring Bldg for LINAC, booster and storage ring installation to begin as early as March 2010 • Beneficial Occupancy of Ring Building & LOB - June 2011 • Control/Computer room availability & CLOB BO August 2011 • Conventional Construction complete - October 2011 21 BROOKHAVEN SCIENCE
