Construction (Underground) Project Management: by Acres (now Hatch Energy) – Satish Bhan

Project Manager.

Engineering: Design – Hatch Energy; Geotechnical – Itasca; Excavation - Macintosh.

Excavation: Contracted to J.S.Redpath Ltd.

Phase I: Began Nov 2004, completed May 2007

Phase II: Began Jun 2007, completed Jun 2008

Total excavation 6000 m2 / 39,000 m3.

Outfitting: Contracted to Comstock Canada Ltd with sub contracting for specialties.

Began Jun 2007

Done: Refuge station, Lab entrance

To Do: Completion of Utility Area (chillers, stp, fire water system); Ventilation in Ladder Labs, Cube Hall and Cryopit

Next Steps Contractors

Finish Utility Area: Finish chiller assembly; piping to waste water plant; fire water lines to 6600L; commission chillers, STP.

Finish work in Experimental Areas: running water lines to Cube Hall and Cryopit; hook up electrics; Building Automation System; Fire Alarm.

SNOLAB Fine cleaning of Personnel Area (showers, change

rooms, lunch room, meeting room). Fine cleaning of laboratory entrance (carwash, junction,

access drift to SNO facilities). Services including network Infrastructure, water

pretreatment (relocation), up size 13kV power feed, ...


Finish Line Day 1

Support Facilities: Enlarged personnel area and material handling facilities.

Experimental Spaces: Existing SNO Cavern, Cube Hall, Ladder Labs all operated as Clean Rooms. Cube Hall and Ladder Labs will be “bare rooms” but with nearby services.

Day 2 Cryopit: Paint and fine clean. South Drift: Remove old carwash and personnel

facilities. Recover as experimental space. Underground “clean room” machine shop. Underground chemistry lab.


Day 1 Infrastructure Power Distribution

2000 kVA capacity at 600V. 400A/600V services to the experimental areas except the Cryopit (deferred). Able to accommodate a future backup generator.


Future

Day 1 Infrastructure Power Distribution


Day 1 Infrastructure Cooling

300 T (1MW) Chiller; Chilled Water Loop: 250 PSIG, 5C. Distribution to SNO Utility, Cube Hall and Cryopit.


CHILLER

Day 1 Infrastructure Ventilation

Main ventilation hard ducted. Distribution into Experimental areas with soft duct. 5-10 air changes per hour. HEPA filtered.


Day 1 Infrastructure Communications

Multimode 200 Mb/s capacity between surface and underground. 1 Gb/s off site.

Will complete a Gb/s single mode fibre link between underground and surface in the near future.


Day 1 Infrastructure

Other Services

Industrial water, fire water, forced drain, compressed air.

Ultrapure water from the SNO water purification plant.

LN2 supplied by transport dewar from surface.

Low Background Counting

1 existing HPGe Gamma Counter. Requesting funds for 2 additional counters.

Rn/Ra Emanation (Electrostatic Counters, Radon emanation.


Staff

Staff of ~40 Operations: Cleaning, material handling, maintenance,

lab supervision. Technical Support: Plant operations, chemistry, electrical,

electronics, instrumentation. Design: Primarily mechanical and process systems

expertise. Design work, reviews. Construction: Small construction group with expertise in

the SNOLAB related issues. Assists with experiment installation.

IT: Networking, system administration. Admin: Procurement, shipping and receiving, training.


Experimental Program The experimental program has concentrated on

astroparticle physics but has also had submissions from other fields such as seismology and fundamental constants.

Requests for space are reviewed by the Experiment Advisory Committee (EAC) which makes recommendations to the Director. To date 25 Letters of Interest or proposals have been

submitted, 13 of which have been recommended by the EAC as appropriate for pursing for siting at SNOLAB. Of these 8 have developed mature plans to come to SNOLAB.

Beyond Construction With the laboratory almost complete, construction

emphasis is shifting to facilitating the siting of experiments.

Cube Hall: Begin steel work for DEAP/CLEAN and MiniCLEAN.

SNO Cavern: Repair of liner floor and install of hold downs for SNO+.

SNO Utility Rm: Excavation of pit for SNO+ scintillator plant.

Renovation of South Drift, old Carwash, ...

Summary

Construction is almost complete! Ready to begin the installation of the Day 1

experiments. Civil work can being any time in the new laboratory areas. We plan to install steel in the Cube Hall at the

beginning of 2009. Some space has been allocated for

experiments but there is still significant room available.

SNOLAB is open for business.
