Project Schedule § Currently at a stand still § Complexity § Safety issues § Install should still be okay for originally planned September install § General Cleanup 2 -3 weeks prior to shutdown of substation § Temporary electrical power will be setup the weekend prior § It could take riggers several days to remove and install substations § Small clearances § Large weights § May be several more days if given okay to shore the floor

Issues § Substantial Weight Increase § 10, 500 lbs. vs. 17, 700 lbs. § Gallery floor has a very low load limit (350 lbs. /sq. ft. ) § This could effect everyday operations § Fork lifts, Tour groups, Removing equipment from downstairs § Could be wrong § Stevenson has no suitable indoor crane § Ceiling height is too low for carrydeck crane § 55, 000 lbs. § Shoring the floor may not be a possibility § Much of the transformer will need to be dismantled § Secondary bus bars, frame, sheet metal § Increases electrician time

Suggestions § FESS has been notified that it needs to begin looking into ways to fix this issue § Cut a hole in the ceiling § Has been done at other sites around the lab § Install outside § Requires Federal to make outdoor gear § Engineering Expense § Siemens subcontract issue § Expensive cable runs § Rigging job would be simplified § Aesthetics committee

Temporary Power Plan § “Siphon” power from panel DHP-L 2 -2 Circuit #1 § Cable will be run on temporary supports § 4 conductor 350 mcm cable is heavy (~7 lbs. /ft. ) and will need an open area to lay § Some cable will be put on the floor but will be covered by a cable bridge § Setup 2 temporary panel board(s) § Run cable to individual loads § DHP panels, MCC loads § DHP panels will be locked out and tagged out § Group lockbox § MCC loads will have configuration control locks § We will check current prior to using any MCC loads to ensure they will not trip off during operation § Power will be provided 24 hours a day

Installation Costs § 1 Crew of Riggers (4 -6 men) § Unknown Cost § Will remain unknown until a plan is put in place by FESS § 2 Week of Electricians § $100/manhour x 2 electricians x 80 hours = $16, 000 § Cable § 2/0 - $3, 500 § 2 – $3, 700 § House Power § $4, 200 for panelboard § $2, 000 for assembly § Miscellaneous Stock purchases § $2, 100 Total Cost : $31, 500 -> excluding rigging Previous Estimate: $23, 000 -> excluding rigging Increase can be attributed to increased electrician time and panelboard cost
