5 BROOKHAVEN SCIENCE ASSOCIATES Building Program

6 BROOKHAVEN SCIENCE ASSOCIATES 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

7 BROOKHAVEN SCIENCE ASSOCIATES Experimental Floor Arrangement

8 BROOKHAVEN SCIENCE ASSOCIATES Experimental Floor - Ring Building Section

9 BROOKHAVEN SCIENCE ASSOCIATES 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

10 BROOKHAVEN SCIENCE ASSOCIATES Floor Plan – CLOB 1st

11 BROOKHAVEN SCIENCE ASSOCIATES Floor Plan - CLOB 2 nd

12 BROOKHAVEN SCIENCE ASSOCIATES Floor Plan – CLOB 3rd

13 BROOKHAVEN SCIENCE ASSOCIATES 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 Designed to minimize impacts to future long beamlines

14 BROOKHAVEN SCIENCE ASSOCIATES Lab – Office Building

15 BROOKHAVEN SCIENCE ASSOCIATES 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 ” Building loads isolated from tunnel and experimental floor slab Access corridor isolated from experimental floor slab

16 BROOKHAVEN SCIENCE ASSOCIATES 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 & vibration measurement

17 BROOKHAVEN SCIENCE ASSOCIATES 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, 75-95kW/Cell, 120/208V Cooling Water, HVAC Supply Air, Exhaust Compressed Air, LN 2, GN 2 DI Water (Copper and Aluminum) by Accelerator Group

19 BROOKHAVEN SCIENCE ASSOCIATES Temperature Stability Key temperature stability requirement is tunnel +/- 0.1C 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 +/- 1F, 30% RH +/- 10% RH
