8. Near Detector - Requirements 16SEP14S. Dixon | Conventional Facilities Update8 From D. Montanari 129m3 Version 231m3 Version

9. Design/Cost Estimate Process – Target: $3.5m July 2014 Design Refined – 2 designs at 2 locations August 2014 - External Estimate –129m3 Version - $4.3m (total project cost) –231m3 Version - $5.1m (total project cost) Scope Reductions – focused on 129m3 version –Eliminated additional loading dock bay –Removed toilets/utilities –Removed cryostat concrete –Reduced siding cost –Onsite disposal of excess spoils –Moved overhead crane from Base Scope to Scope Contingency August 2014 - External Estimate - $3.5m (total project cost) 16SEP14S.

14. Near Detector Building – Potential Changes 16SEP14S. Dixon | Conventional Facilities Update14 Overhead Crane Base scope does not include the crane, only the structure capable of supporting a crane; Recognize that a crane is needed for installation; Cost for 10 ton crane is ~$140k Project Plan (section 2.1 on page 12) identifies the crane as one of the highest priorities;

15. Near Detector Building – Potential Changes Reduced Size of Lower Level 16SEP14S. Dixon | Conventional Facilities Update15

16. Near Detector Building – Potential Changes 16SEP14S. Dixon | Conventional Facilities Update16 Shielding - #1 Move enclosure north of SciBoone by ~10 feet;

17. Near Detector Building – Potential Changes 16SEP14S. Dixon | Conventional Facilities Update17 Shielding - #2 Be able to accommodate 9 feet of shielding above the detector; Current Span (30’-8”) is longer than standard shield blocks 24’ “G” Block = 22’ clear * 30’ “N” Block = 28’ clear ** Revised Ledge Raise ground level Larger crane * Standard Fermilab Block, but availability uncertain/unlikely (7.7 tons) ** Non-standard Fermilab Block (9.7 tons)

18. What’s Next Project Plan (SBN-doc-72) Issued for Comment and Compliance Review Revise document based on comments Ready to submit for FY15 funding in October 2014 Subsurface Investigation Soil boring to confirm the soil conditions Final Design Develop an request for proposal for an AE firm Start Final Design in Spring 2015 (based on construction funding in FY2016 – October 2015) 16SEP14S.
