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, ...
Fraser Duncan SNOLAB Workshop 4-5 Oct 2008
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.
Fraser Duncan SNOLAB Workshop 4-5 Oct 2008
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.

Day 1 Infrastructure Power Distribution
Fraser Duncan SNOLAB Workshop 4-5 Oct 2008
Day 1 Infrastructure Cooling
300 T (1MW) Chiller; Chilled Water Loop: 250 PSIG, 5C. Distribution to SNO Utility, Cube Hall and Cryopit.
Fraser Duncan SNOLAB Workshop 4-5 Oct 2008
CHILLER
Day 1 Infrastructure Ventilation
Main ventilation hard ducted. Distribution into Experimental areas with soft duct. 5-10 air changes per hour. HEPA filtered.
Fraser Duncan SNOLAB Workshop 4-5 Oct 2008
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.
Fraser Duncan SNOLAB Workshop 4-5 Oct 2008
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.
Fraser Duncan SNOLAB Workshop 4-5 Oct 2008
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.

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.
