The scope of work consists of two subprojects: Phase I, Road Improvements and Site Preparation, has been previously approved by the Board. That project includes the upgrade of approximately 3.5 miles of existing logging road to provide all weather access to the Far Detector Building, clearing and grubbing of the building site and the rock excavation for the Detector Enclosure. The excavated rock will be crushed and sized in order to be used as road base and shielding berm.
Phase II is for construction of the 41,000 GSF Far Detector Building. The building consists of a below grade enclosure (approximately 70 feet wide by 70 feet tall and 350 feet long). The enclosure will be situated approximately 40 feet into the rock and will have cast-in-place concrete floor slab and walls. The roof of the Detector Enclosure will be a composite construction of precast concrete planks with a cast-in-place concrete topping. A 0.5 foot deep barite aggregate layer will provide cosmic ray shielding for the Detector Enclosure. Other features of the Detector Enclosure include cast-in-place concrete support spaces such as Computer Room, Control Room and Electrical Equipment Room. The Detector Enclosure will have four levels of steel access walkways on the west side that lead to exit stairs.
The adjacent, at-grade, Service Building will include a Loading Dock, Office, Toilet, Scintillator Equipment Room, Mechanical Equipment Room and Fire Protection Room. The Service Building will be a metal sided, structural steel building with a modified bitumen roof membrane. Adjacent to the Loading Dock is a tanker unloading facility sized to accommodate four (4) trailers and appropriate spill containment.
The mechanical systems for the facility include rooftop HVAC units, sump pumps,ventilation fans and related accessories. The fire protection system for the facility will be a water mist system with 20,000 gallons of onsite water storage.
