LBNF Construction Logistics Planning Parallel nature of construction and installation plans at Far Site over the next 15 years requires close coordination and planning Logistics workshop held Aug at Sanford Lab. Included Sanford Lab Operations, LBNF/DUNE, M AJORANA, LUX/LZ, CASPAR, BHSU UG Campus, and Arup A/E team.  Developed an understanding of Sanford Lab infrastructure & resources  Reviewed plans across all planned activities through 2030  Documented requirements for site infrastructure, resources, interfaces  Developed recommendations to mitigate conflicts & documented risks. Comprehensive Logistics Plan completed that confirms the Ross Shaft will support LBNF/DUNE activities. Yates Shaft provides additional capacity when gas piping is installed in the Ross Shaft. CM/GC will lead logistics planning starting in final design Headley | LBNC: Far Site Update and Planning13

LBNF Planning Outputs: Personnel Underground & Ross Shaft Utilization Key Sanford Lab infrastructure will handle all planned activities At peak, 100 on days 85 on nights 76% utilization at peak including planned maintenance Yates provides margin 14 PERSONNEL HOURS PER DAY

LBNF Construction Logistics Planning: Test Blast Program Excavation design includes a model for vibration & blast air overpressure  Based on industry experience and geotechnical site investigation  Potential risks to other 4850L experiments discussed during Logistics Workshop Headley | LBNC: Far Site Update and Planning15 3 test blasts planned (8’x8’x8’) at intersection of Central Access Drift and the South Drift  Test will confirm model, inform final design  18 instruments were deployed on 4850L  Experiment data collected by LBCs, LUX, MJD  Seismic data will be collected by DUGL, Transparent Earth, GEOXTM First test blast attempted on December 11  Electronic detonators did not perform as expected  Gained valuable vibration and air pressure data  Adjusting blast design and detonator selection  Additional blasts planned for February drill hole / charge layout

LBNF Other recent design changes Removed enlargement of the Yates Shaft brow. The 4850L Ross Shaft station will be enlarged to address transport of long loads. Chambers 3 and 4 will be excavated concurrently Facility adjustments for the detector cavern grounding requirements Monorail crane capacity increased to 15 metric tons. Central Monorails extended 3m into both ends of each detector cavern with laydown space. Transverse beam design included for bridge crane-like flexibility. Pillar between detector chambers reduced in width to 14.4m (each chamber pit gets 0.3m longer to support side installation). Underground power requirements increased (225 kVA transformers now 500 kVA) Temperature requirements in detector caverns changed to F Headley | LBNC: Far Site Update and Planning24
