5. LBNF Topics covered 08.19.15Mike Headley | Logistics Workshop Summary5 Infrastructure overview Surface and underground tours Presentations by SURF operations, LUX/LZ, Majorana, CASPAR, BHSU Underground Campus (low background counting) LBNF/DUNE presentations by CF, cryostat, cryogenic systems, FD Risk identification / analysis of items related to logistics Arup led discussion of the topics outlined in the logistics scope Presentation of information captured in excel-based toolset to track SURF infrastructure usage over time

6. LBNF Key items reviewed in evaluating infrastructure usage 08.19.15Mike Headley | Logistics Workshop Summary6 Each group provided a detailed presentation on schedule and infrastructure needs and a resource usage spreadsheet Key constraints  Shaft access  Big X  Governor’s Corner Shaft options for LBNF+DUNE  Ross only  Ross + Yates “as-is”  Ross + Yates “upgraded” (assume not feasible for now) We looked at Ross Shaft for ALL work on LBNF+DUNE only

7. LBNF Planning outputs - Assumes Ross Shaft only for LBNF/DUNE (draft) 08.19.15Mike Headley | Logistics Workshop Summary7

8. LBNF Draft schedule and Ross Shaft utilization (Excavation, BSI, and Cryostat phasing needs to be addressed) 08.19.15Mike Headley | Logistics Workshop Summary8

9. LBNF Top 15 risks identified – pre-mitigation scoring 08.19.15Mike Headley | Logistics Workshop Summary9

10. LBNF Mitigations to be considered 08.19.15Mike Headley | Logistics Workshop Summary10 Install concrete slick line borehole from surface to 4850L to remove concrete/shotcrete transport from the Ross Shaft Install boreholes for nitrogen and argon gas delivery to 4850L Assuming LBNF/DUNE utilize Ross Shaft for transport of long loads (up to 17m), modify Ross Headframe accordingly and/or evaluate shortening of cryostat steel beams to ease installation Utilize Yates Shaft as is – do not modify for long loads and avoid impacts to Davis Campus experiments Plan and conduct controlled blasting test program to evaluate impacts for LBNF excavation on other 4850L inhabitants Evaluate acceleration of phase 1 excavation to speed cryostat 1 installation and thus FD installation. Adjust EXC, BSI, and cryostat schedules to fix phasing of CF to cryostat installation
