4. LBNF Control Room Requirements: Minimum 400 GSF for 10 occupants Data connection and fire alarm system connection All data systems provided by experiment HVAC to maintain personnel comfort and control data rack temperature Design: Utilize existing room within Ross Dry Building Make ADA compliant (this is the only scope with this requirement) Lead AHJ has formally approved this 07.15.15Joshua Willhite | FSCF Scope4

5. LBNF Power Supply Existing Ross Substation has 20 MVA capacity, using ~5 (plenty of capacity) Surface Power Requirement: ~5.3 MW Underground Power Requirement: ~2.9 MW Add additional switchgear in substation for new feeders Utilize existing utility bridge to connect to existing steam tunnel Protect new cables by embedding conduits within new concrete floor in the steam tunnel Split power at shaft, one cable set feeding the underground, one feeding the surface compressor building and control room 07.15.15Joshua Willhite | FSCF Scope5

7. LBNF Cryogenic Compressor Building Interfaces and Requirements Cryogenics group responsible for dewars, purity monitoring system, vaporizers, compressors, and gas piping inside the building CF responsible for building, civil works, cooling towers, coolant recirculation, power supply (normal, emergency, standby), and gas piping from building to the underground. Cryogenics group defined building footprint by providing drawings and compressor specifications. (DocDB 9965)DocDB 9965 Compressor sizing and pipe sizing is based on desired filling rate of the detectors. Once full, fewer compressors will operate to circulate nitrogen to the underground. 07.15.15Joshua Willhite | FSCF Scope7

11. LBNF Other Surface Scope (early work managed by SURF) SURF has identified several surface projects that are believed to pose risks to the facility and should be addressed prior to LBNF construction as follows: Near-surface adit repairs (Tramway, 300L) Crusher building roofs at both shafts Hoist upgrades (motor rebuilds) Headframe reinforcement at both shafts Administrative Building Parking lot/roadway Oro Hondo Fan 07.15.15Joshua Willhite | FSCF Scope11

12. LBNF Shaft Scope Utilities in the shaft include: Power Fiberoptics for data separate from fire alarm Nitrogen (three 12”, two 8”) and argon (one 8”) gas pipes Concrete slick line for construction in 6 winze Fire water pipe from 4100L to 4850L Existing 4” water line will feed a sump at the 4100L and continue past to service other water needs. 6” fire line from 4100L sump to 4850L Other shaft scope (early work managed by SURF): LBNF paying for 2016/2017 rehab New cage and skips 07.15.15Joshua Willhite | FSCF Scope12 Changing for 100% (2) 16” N2 pipes rather than (3) 12”

13. LBNF Yates Shaft Scope For the 100% design, Arup is including the following work for the Yates Shaft: Removal of bracing in the headframe to accommodate 17m long beams Replacement of timber within shaft from just above the 4850L to the bottom with steel Raising the brow at Yates to accommodate 17m long beams Enlarging the 4850L station to allow beams to come out of skip compartment Mike Johnson is working on special conveyance designs to expedite beam delivery. This is not in Arup’s scope. The corner beams are an unsolved problem at this time. 07.15.15Joshua Willhite | FSCF Scope13

LBNF Monorails 07.15.15Joshua Willhite | FSCF Scope18 For 100%, two monorails located 1.5m from side walls, one centered on cavern No known height requirement, so placed as close to back as possible 10 metric ton capacity meeting deflection criteria of L/1000 5 m gap between detector caverns to allow room for utilities to cross caverns Beams do NOT extend into east or west access drifts – only to cavern end (see next slide) Unclear interface with clean room

26. LBNF Controlling Impacts to other Facilities The Davis Campus is ~1 km upwind of LBNF, so controlling impacts to this campus during construction is relatively straightforward. The Ross Campus is fairly close - ~100m from the nearest extent of the campus to the nearest excavation. CF proposed a limit of 0.5 in/sec vibration and 134 dBL air blast overpressure, both derived from standard mining criteria. The two primary users of the Ross Campus (CASPAR and BHUC) accepted these recommendations. 07.15.15Joshua Willhite | FSCF Scope26

27. LBNF Vibration Control (load size vs. vibration) 07.15.15Joshua Willhite | FSCF Scope27

28. LBNF Air Blast Control Most extreme situation is when building a cryostat in cavern 1 while blasting the second pit due to proximity and cross section – draft concept shown at right (under development) Control at Ross Campus is most challenged by retaining ventilation 07.15.15Joshua Willhite | FSCF Scope28

29. LBNF Life Safety Life safety analysis has defined compartmentation layouts and fire rated egress pathways in each phase. Note that ODH analysis and control is the responsibility of the cryo group, who have defined minimum air flow. Compartmentation for fire events also provides for ODH, but is not designed specifically for it. An existing refuge chamber is currently outfitted for 72 persons, 96 hours occupancy. One SURF Operations project is planning to upgrade this room to support as much as 150 occupants. Any refuge needs beyond this upgraded chamber during construction will be the responsibility of the construction contractor. A logistics study will be completed later this year to understand potential occupancy for all stakeholder. A draft life safety assessment has been posted to DocDB 4395 evaluating the current scope and offering suggestions for improvement.4395 07.15.15Joshua Willhite | FSCF Scope29

36. LBNF Plumbing and Fire Suppression The cryogenic gas pipes that come through the shaft are taken to the west entrance of the central utility chamber – then responsibility transfers to the cryo group. Water is only required for the HVAC system (spray chamber makeup, cooling) and fire protection. Both will use industrial water supply. Potable water is provided via UV treatment (identical to Davis and Ross Campus systems) for miscellaneous use (no actual requirement exists). Fire suppression systems (sprinklers) are provided in all areas (except mucking ramp) created for LBNF. Hose stations are provided every 200 feet as well. 07.15.15Joshua Willhite | FSCF Scope36

LBNF Controlling EMI To control electrical interference between facility and experiment electronics, separate shielded transformers are provided, and the experiment ground is isolated using inductors and insulators. Additional requirements have been stipulated to avoid ground paths through detector caverns and provide minimum cable lengths to dampen EMI frequencies. 07.15.15Joshua Willhite | FSCF Scope40

45. LBNF Waste Rock Handling - Surface The surface waste rock handling included in this design was developed during the 60% preliminary design for DUSEL. No updates were made beyond updating costs based on escalation. A design-build contract is planned to capture all waste rock handling scope from the skip discharge to a truck loading system as shown on the following slides. 07.15.15Joshua Willhite | FSCF Scope45
