## Conventional Facilities WBS

## Building Program

## Ring Building Concept

**Ring Building 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

- Area of initial Operations

## Ring Building Section

## Experimental Floor Arrangement

## Tunnel Design 

- Roof and wall thicknesses generally driven by shielding criteria except inner wall in area of berm (just structural)
- Outer wall (ratchet wall) is HD concrete
- During T-I will study whether precast or poured in place provides best balance of technical and cost performance
- Tunnel floor thickness driven primarily by vibration criteria
- Will do modeling  to arrive at optimal thickness and section shape
- Rigidly connected to exp. floor to create monolithic floor
- Penetrations from above for power and cooling water
- Penetrations from sidewall for HVAC  Supply and Return

## Tunnel Access

- Egress for life safety achieved by exits at each service building location
- Large shielded doors for equipment access provided at Service buildings for tunnel entry
- Mandoors and labyrinth provided at each Service building
- Vehicle ramp to roll-up door at 2nd floor of each Service Bldg provides equipment access to electrical mezzanine at top of tunnel
- RF & LINAC areas integrated with CLOB structure have similar access as Service Bldgs

## Service Bldgs

## 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
- 2nd floor viewing gallery overlooking experimental floor
- Bridge to electrical mezzanine and control room & RF/LINAC areas
- Close Proximity to future:
- JPSI Building
- Guest house

## 1st Floor Plan – CLOB

## 2nd Floor Plan - CLOB

## 3rd Floor Plan – CLOB

## Section at CLOB

## CLOB & Ring Building

**CLOB & Ring Building**

## 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

## Lab – Office Building

## Lab-Office Building

**Lab-Office Building**

## 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 Beamline include:
- Electric Power Panel at Ratchet Wall, 75-95kW/Cell, 120/208V
- Cooling Water, HVAC Supply Air, Exhaust
- Compressed Air, LN2, GN2
- DI Water (Copper and Aluminum systems) by Accelerator Group

## 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
- Minimizes potential noise and vibration impacts
- Mechanical Utilities include:
- Chilled water from expansion of Central CHW Plant
- Tower water from process cooling water tower
- Steam & condensate from Central Steam System
- Potable water, compressed air, sanitary to existing mains
- Electrical Utilities distributed via substation and load center at each services bldg
- Communication/Data via underground BNL F/O network

## Schedule

- Key schedule objective – Enable start of accelerator installation  March 2010
- CF is critical path until the main bldg spaces are  turned over for accelerator installation
- Cluster areas of Ring bldg to be released for BO in phases
- Key durations:
- Title I Design – 9 months
- Title II Design – 10 months
- Site preparation – 6 months
- Main bldg contract bid & award – 6 months
- Main bldg contract duration 34 months

## Risks & Challenges

- Technical Challenges
- Constructing massive concrete tunnel with reasonable economy
- Achieving structural stability
- Minimizing differential settlement
- Vibration mitigation
- Achieving thermal stability –
- Tight temperature constraints for tunnel
- Assuring interior/exterior thermal gradients don’t affect beam
- Making tunnel available for accelerator installation in phases
- Risks
- Cost sensitivity of achieving all of the above
- Volatile material/construction markets
