ITEM STATUSHall A & UtilitiesFloor rise at the pivot needs survey & concrete leveling during install

Floor plates

GMn uses 10 of 15 SBS floor plates, Have 10 plates. GMn uses 9 of 16 HCAL floor plates, Catania has 7 plates on order.

Move BB rails to BL during installHRS-BR interferences - move air handler, move catwalk post at pivot, install access platform to access cryo can at pivot Modify & use Tritium platform, pre-install workLCW upgrade needs engineering check & purchase

BEAMLINEClear utilities supported along existing beamline during installMove and modify existing beamline supports during installModify existing beamline flanges doneNew beamline conical pipe doneBeamline shielding doneBeamline assembly hardware design tested, needs purchasingSupport tower doneSupport tower extension delivery Nov 30, 2018Vertical supports redesigned, needs purchasingCorrector magnets done

Summary

October 20189

Completion requires 24 mw design and 18 mw engineering

Hall A has staff of 2 engineers, 1 associate engineer and 3 designers.

Present workload and priorities, allow all SBS GMn engineering & design to be complete by mid-March 2019. This does not include fabrication. The GEn polarimeter design work is not included in this schedule.
