The red areas show the current extent of excavation for SNOLAB.  Excavation for Phase I of SNOLAB has reached the Rectangular Hall.  The Ladder Labs are fully excavated and are undergoing the final installation of rock and cable bolts to secure the ground prior to application of the shotcrete liner.

Laboratory Entrance

	The laboratory entrance is the transition from the dirty mine areas to the clean room laboratory.  It includes a rail yard for unloading shipments brought underground on a narrow gauge railway, a "carwash" to clean equipment and a personnel area including change rooms and showers for personnel.
	Shotcreting of the existing drift between the new laboratory entrance and the existing SNO facility Carwash is underway.

Ladder Labs

	The Ladder Labs are a network of drifts (mining terminology for tunnels) intended to house several medium scale (several meter sized) experiments.
	The "lower rail" access drift for the Ladder Labs is fully excavated.  This drift is used for access to the ladder lab experimental areas.
	The larger rail (north side) of the Ladder Labs has been excavated.  Ground control consisting of 7m cable bolts is being installed in preparation for shotcreting.  This view is looking back towards the larger end of the Ladder Lab Excavation.  An access "ladder rung" drift leads off to the right at the end of the excavation.

Rectangular Hall

	The Rectangular Hall is a large hall located north of entry to the laboratory intended to house a large scale (10 m sized) experiment.  In addition to the experimental hall there is a staging area, control room and utility room to support activities in the hall.
	The excavation of the Utility Drift for the Rectangular Hall is nearly complete.  This drift will house support services for experiments being conducted in the Rectangular Hall.
	The furthest excavation north towards the Rectangular Hall.  A drift is now being driven to the right from the end of this space towards the location of the Rectangular Hall.  The space shown here will be used for a staging area and control room for experiments in the Rectangular Hall.

Cryopit (Phase II)

The excavation of SNOLAB is structured in two phases.  Phase I which is presently under construction is the creation of the Rectangular Hall, Ladder Labs and the new personnel facilities.  Phase II would add a second large experimental cavern called the Cryopit intended for large scale cryogenic experiments.  Phase II is not presently funded.

Utility Area

	The Utility Area contains the chiller system to cool the laboratory and the emergency diesel generator.  It is located old mine workings outside the clean room space of the laboratory.
	The "Chiller Drift" will contain a 320 Ton chiller system to cool the laboratory.

Existing SNO Facility

The SNO experiment continues to operate without significant disruption during the excavation of the new SNOLAB facilities.  SNO is scheduled to end data taking at the end of 2006 and will be decomissioned during 2007.

Surface Facility

	The SNOLAB Surface Facility.  A 34,000 sq ft facility to provide support for experiments underground as well as office and meeting room space.
	The surface facility is equiped with several class 1000 clean room laboratories for prototyping and staging for experiments being deployed underground.
	Many of the radiological assays for ultra low background experiments require chemistry to enhance the detection of radioactive trace elements.  A clean room chemistry laboratory in the surface facility provides support for the experiments.
	A Low background counting laboratory is used to measure minute quantities of radioactivity assayed from the SNO experiment.
	The surface facility has several meeting rooms including a 100 seat auditorium.
